Can you remember your Dream !

People often say that they can't remember what they dreamed about last night except some situations when the dream is either too joyful or a scary nightmare. Even if you can remember a dream just after waking up then most probably you will forget it within a few hours. Chances of remembering dream are more when you get awake in middle of it. Those who study sleep and dreams know the reason why you can't remember all your dreams.

Dreams are meant to be forgotten

On an average we sleep for one-third part of our life. 20% of that time is REM (Rapid Eye Movement) Sleep during which we dream. Everyday we dream at least 5 different dreams. If our brain remembers all those dreams then it will take a lot of memory. Remembering all those dreams can also make it harder for us to distinguish between real memory and dream memory, as sometime dreams revolve around real subjects and circumstances. We are meant to forget dreams only to make our life easier. Sometimes the dreams are either too joyful or too scary and remembering them for long duration can take us away from reality in actual life. Usually we remember only the last dream that we had last night and the chances of forgetting that dream within a few hours are quiet high. The probability of remembering a dream increases if we wake up in middle of it.

Science behind Sleep and Dreams

If you study a little about sleep cycle the then you will come to know that sleep can be put into two main stages: REM (Rapid Eye Movement) Sleep and Non-REM Sleep. Non-REM Sleep can be further partitioned into four different stages. Out of these stages "Stage 4" is the deepest sleep during which we never dream and our body repairs broken tissues and builds bones and muscles. We dream during REM phase and the duration of REM phase increases as the sleep cycle increases and so does the duration of your dreams. So most probably your last dream will be lengthier than other dreams and may take up to 1 hour of your sleep. If you try to remember your last dream within 45 seconds after waking up then most probably you will remember that.
50% sleep time of babies is dedicated to REM sleep, while this duration decreases to 20% in adults. It means that kids dream more than adults. You may notice the kids dreaming by noticing the movement of their eyeball inside their closed eyes, which is easily visible (that is why they call it REM, Rapid Eye Movement). Due to more REM sleep in kids, the probability of remembering a dream increases in them.

The more time we take after REM phase to wake up, the lesser are the chances of remembering that dream. So now you know why we remember some dreams while some we don't. And the dream that we remember is usually the last dream of that sleep.
Creative people do remember their dreams more often. A number of extra ordinary scientists have have accidentally made some discoveries through their dreams.

Strongest Muscles in Human Body

Muscles are something that makes us feel stronger. But which muscle in human body is strongest ? But reality is that definition of strength is different for different conditions. Some muscles are strongest in terms of working continuously for longer duration while some muscles are best in giving huge amount of pressure within a few seconds. So based on these different definitions of strength, you will come to know about different powerful muscles in human body in this article. If we declare any one muscle of body as the strongest muscle then it would be injustice to more than 800 other muscles.

We collected a list of different muscles whom we can call as strongest muscles of our body. Out of these muscles we can't give the status of number one to a single muscle, as all of them do exceptionally were at their respective places in our body. We can't even think about surviving without any one of them.

Cardiac Muscles: These muscles make the wall of the heart and contract to pump the blood to the whole body. These muscles never rest and stop only when a person dies. They do the hardest work in body and never get tired. 2 ounces (71 grams) of blood is pumped in every heart beat. It means daily 2,500 gallons (9,450 liters) of blood is pumped. Cardiac muscles are involuntary and can't be controlled at will.
Masseter Muscle: This  facial muscle helps us in chewing food by exerting pressure on food through our jaw. These muscles help us put pressure of 200 pounds (90.7 kilograms) on the molars and 55 pounds (25 kilograms) on the incisors. This pressure is sufficient to chew any solid food and get the best taste out of it.
External Muscles of Eye: These muscles are best in terms of coordination with our body. We can't see an object properly without these muscles. They help us in maintaining a focus any object either it is still or moving. They even help us in not losing the focus even when your own head moving or shaking. 10,000 coordinated movements are made by these muscles within an hour while reading a book. So you can easily imagine how much stress they bear when you are running or driving. These muscles get tired and need rest in the form of sleep.
Gluteus Maximus: These muscles are inside our hips and the largest muscle in our body. It help us in keeping our posture erect. Without this muscle we can't even think of standing straight and walking upstairs.
Uterus Muscles: These muscles work at the time of delivery of a baby by contracting the muscles of Uterus to push the baby out. Pituitary Gland secrets oxytocin hormone to stimulate contraction of these muscles.
Soleus: This muscle is responsible for walking, running, standing, dancing and making balance. It is also known as the anti-gravity muscle of human body as it works against the force of gravity. It is present in our leg just below the calf muscles(gastrocnemius).
Tongue Muscles: There are many muscles inside our tongue working at different levels. It has got one of the toughest job to do, i.e.pushing the saliva into our digestive system. It also helps in mixing the food while the food is being chewed by our teeth. It works with great coordination with our teeth and never get cut.
Rectus Femoris: This muscle helps in kicking or sprinting. This muscle connects our hips to knees and helps in extending or raising the knee. Injury in this muscle is mostly found only in soccer players due to its over usage.

All of the above muscles are strongest in one or other way. Their sequence in this article has nothing to do with their ranking. You will never want to get any of these muscles hurt in any way in your lifetime.

Whose muscles are better: Athlete or Bodybuilder ?

Health conscious people often compare the body/muscles of an athlete with bodybuilders. The truth is that even professional bodybuilders can't beat the strength of muscles of a professional athlete. The looks of a bodybuilder's muscles might be more fascinating compared to an athlete, but not the strength. Even the best bodybuilder in the world with best leg muscles can't beat Usain Bolt on a racing track.

What makes muscles of an athlete work better than a bodybuilder ?
Muscles of an athlete are trained for strength, while muscles of a bodybuilder are made to look bigger in size. There is a major difference between their body types. More strength in the body of an athlete is a result of better nervous system. Bigger muscles are not a proof of better nervous system functioning behind. More power generated by athlete's muscles is done by both muscles and nerves connected to brain. It would not be wrong to say that real strength lies in your brain. Practice is necessary in both cases, but exercises of a bodybuilder are totally different from athletes. Training programs of an athlete train their nervous system equally with their muscles.

Science behind improving nervous system for more strength

Intense physical activity causes motor unit recruitment to increase the strength. Motor Units (motor neurons connected to muscle fibers) make our muscles contract by bringing the electrical signal sent by brain from spinal cord to muscle fiber. Motor Unit Recruitment is activation of more motor units. Intense physical activity activates more motor units and thus increases the strength of contraction of muscles.

Our brain fires electrical impulses to motor units to contract a muscle. The strength of contraction depends on two factors.
  • How many muscle fibers are connected to each motor unit.
  • How fast is the firing rate of electrical impulse sent fro brain to motor unit.

Regular intense physical activity increases both of these factors. It increases the strength of contraction by 2 to 4 times. 
When we exercise regularly our brain get used to increased blood supply and adapts the ability to turning some genes ON and OFF as per need of body at that time. When we exercise our body take that moment as a moment of stress, due to increase of blood pressure and breathing (as if we are fighting or fleeing from some enemy). To protect our brain from this stress a protein called BDNF (Brain-Derived Neurotrophic Factor) is released, which empowers our memory neurons.
So in more easy terms you can say that exercise or intense physical activity not only increases your muscle size but also improves your memory and ability of your nervous system to contract your existing muscles with more power.

Athlete versus Bodybuilder

After reading all of the above content you will believe it if we say that size has nothing to do with actual strength.
  • Body of a professional sportsperson is trained to use its muscles with speed and strength. While the body of a bodybuilder is trained to show how much it can pump .
  • No matter how big are muscles of bodybuilder, they can't push the body to attain the speed of an athlete. It is due to lesser motor unit recruitment, which empowers the nerves behind the muscles to show more strength at a certain time.
  • The coordination between different body muscles is better in athletes/sportsperson. Even eye's coordination with other body parts is better in them.
  • Muscles of a bodybuilder may be bigger but their flexibility is lesser that a sportsman. 
  • Muscles of an athlete can bear more burden for a longer duration. Again it is due to better nervous system functioning behind.
If you understand the difference between exercises of Athlete and Bodybuilder, then you will be better able to know why athlete's muscles work better in certain sports while the bodybuilder's bigger muscles can't do that.

Do you think that Bodybuilding makes you stronger ?

If you use to think that bodybuilding makes you stronger, then you might be wrong. A recent research which compared the muscles and power of bodybuilders with some physically active men, found that both have same amount of power in their muscles. However the size of muscles of bodybuilders is larger comparatively but it has nothing to do with actual strength. Sometimes a physically active person with lesser muscle size may be more powerful than a body builder who just looks more powerful.

Bodybuilding increases Size not Strength

If you understand the science behind bodybuilding you will understand that it is an art to make your muscles bigger and make them look better in a desired shape. But the real strength lies behind muscles, i.e. you nervous system. The mechanism of strength lies in your brain and nervous system. Improving this mechanism is not an objective of bodybuilding. However some strength increases in bodybuilding but that improvement is not as much as it appears.

Science behind increasing Muscles Size

There are three types of muscles: cardiac, smooth, and skeletal. Cardiac muscles are located at heart and they are involuntary muscles (that we can't control at will). Smooth muscles are located in walls of hollow visceral organs. Skeletal Muscles are connected to out skeleton and allow us to move different body parts. Skeletal muscles are the main muscles that we target in body building. If we keep these muscles under tension for longer duration then their size increases with time. Some strength also increases with it. But real strength lies in the our nervous system and there are different ways to improve and strengthen your nervous system.

How does muscles size increase by body building ?
When we exercise our muscles consume instant energy called ATP and demand more energy/glucose from body. To provide that energy and oxygen, our breathing and pulse rate increases. But still due to insufficient oxygen, lactic acid is released in muscles which makes tiny tears in muscles and we start feeling pain. These small tears in muscles are repaired by body during resting phase and they grow bigger and stronger. The key to growing muscles bigger lies in keeping your muscles under tension for longer duration, which can done by using lesser weight with more repetition. The weight should go up and come down in a controlled way to fulfill this objective. Proper amount of rest is also necessary to give adequate amount of time to let the muscles heal and grow. 

The motive of this article is not to demotivate you from body building. Body building makes you look better than before and it is better than sitting idle and being overweight. It is a good way to burn calories and living a healthy life. It can make you look like a superhero but in reality it doesn't mean that you will be able to lift weight like power lifters. Body building and weight lifting are two different things and its better to understand them if you want to make anyone of them your career.

Kidney Disease Stages and Symptoms with Life Expectancy

Kidney Disease is a condition when one or both kidneys face certain lack of efficiency in filtering the blood. Kidney Disease is also know by names such as CKD (Chronic Kidney Disease) or Chronic Renal Failure. It can happen due to various other medical conditions over a large period of time. Sometime some medicine meant to treat other diseases can put harm to kidney function as a side effect. The damage to kidneys can be put into 5 different stages. Different stages of Kidney disease have different symptoms and stage 5 is considered as worst where life expectancy is greatly reduced.

Usually Kidney Failure doesn't happen at once. It happens in different stages as the condition worsens. Symptoms of different stages are different and symptoms worsens as the stage of Kidney Disease increase.

Kidney Disease Stage 1 and 2 Symptoms

Stage 1 and 2 of Kidney Disease are generally considered as early stages, hence the symptoms are generally mild and not noticed as something serious. People often take them as symptom of some other disease. During first 2 stages of Kidney Disease, the efficiency of Kidneys may get reduced to just 50%. Some symptoms of Kidney Disease Stage 1 and 2 are:
  • There are no physical symptoms in these stages.
  • Heavy Proteinuria: It means proteins from blood leak into urine due to damaged filters in kidney. It makes the urine more foamy. However this symptoms can also occur due to some other diseases and drugs as well.
  • Blood in Urine: This symptom can also occur in some other diseases like UTI.
  • In some cases blood pressure may also rise due to Kidney Disease.
  • Anemia may also occur in some rare cases. 

Kidney Disease Stage 3 and 4 Symptoms

During Stage 3 and 4 the efficiency of kidneys get reduced to just 30%. 
  • Tiredness and fatigue are common in these stages.
  • Physical symptoms like puffiness around eyes, swelling in hands, feet and ankles.
  • Back pain can be felt in lower back on either side.
  • Color, amount and frequency of urination will change.
  • Eating pattern changes naturally and food starts tasting funny.
  • Blood Pressure remains elevated.
  • Serum creatinine will be higher in these stages, which can be found by blood tests.

Kidney Disease Stage 5 Symptoms

Stage 5 of Kidney Disease is End-Stage and also known as Kidney Failure or Renal Failure. In this stage the kidney function is reduced to just 10 to 15%. Symptoms become severe and doctors often recommend dialysis and kidney transplant. Symptoms of Stage 5 of Kidney Disease include symptoms of all previous stages and some more symptoms listed here:
  • Headache
  • Lower mental alertness / Confusion
  • Difficulty in breathing
  • Decreased urine output. However in some cases urine output increase, but that urine is more like plain water and no body wastes are expelled through it.
  • Itching in Skin and Eyes
  • Skin color changes to grayish or yellowish complexion.
  • Swelling and puffiness increases more than previous stages.

Kidney Disease and Life Expectancy

Life expectancy is not an issue in first 4 stages of Kidney Disease, if proper treatment and lifestyle changes are adopted by the patient. But if the patient has entered stage 5 of Kidney Disease then life span may get reduced. As stated earlier that stage 5 is considered as end stage in which both kidneys have almost failed and the only option left is either dialysis or transplant. Life Expectancy of those who undergo dialysis also depends on other medical conditions they are suffering from. The average life expectancy of patients on dialysis is 5 to 10 years, if they continue to have dialysis as suggested by their specialist. However some patients have lived for 20 to 30 years on dialysis. If a person decides to not to undergo dialysis then life expectancy reduces to just a few weeks.

What causes Kidney Disease and How to Prevent it

Kidney Disease is a medical condition in which the patient faces gradual loss of kidney function. Symptoms of this disease are often not understood and the person keeps living the same life without any treatment. He/she knows that only when Kidney Failure has happened in the final stages of this disease. At that moment doctors either recommend dialysis or kidney transplant. To prevent such things from happening it is better to take care of your health and get some knowledge about the causes of Kidney Disease and how you can prevent it from happening.

What causes Kidney Disease ?

  • High Blood Pressure and Diabetes are themselves responsible for more than 60% cases of Kidney Disease.
  • High Blood Pressure against the arterial walls affect the functioning of Kidney. Blood Pressure is a factor that helps kidneys in filtration of blood. Excess pressure of blood in kidneys reduces their working capability.
  • High Blood Sugar level in Diabetes damages different organs including Kidneys due to neuropathy and atherosclerosis. Neuropathy is damage of nerves due to high blood sugar, which can affect most of the organs but kidney and eyes are most prone to it. Atherosclerosis is damage to arteries due to blood sugar, which can affect kidneys very badly if the sugar level remains high for long duration.
  • Some medicines used to treat other diseases like hypertension, cancer and AIDS can cause Kidney Disease especially when you ignore the side effects of these medicines. 25% of all kidney failure cases can be attributed to such medicines.
  • Stones in kidney can also damage the filtering units of kidney, which is a major reason of Kidney Disease in kidney stone patients.
  • Repeated Urinary Track Infections can sometimes lead the bacteria to Kidneys which can damage the and cause Kidney Disease.
  • In some babies urinary track is not wide enough, which exerts pressure on kidneys and cause kidney damage.
  • Polycystic kidney disease is an inherited disease in which large cysts are formed in kidneys which damages the surrounding tissues.
  • Enlarged prostate gland in men can obstruct the urinary track and cause kidney disease.
  • Inflammation can occur in kidney due to Glomerulonephritis (a group of diseases). It injures glomeruli, which is a part of kidney that filters the blood. It is the third most popular cause of kidney damage.

How to prevent Kidney Disease ?

Living with a healthy lifestyle can prevent Kidney Disease. All the preventive measures mentioned below are part of a living a healthy life. Just adopting them in life can save you from Kidney Disease.
  • Keep your blood sugar in check. If you have diabetes then you should plan your diet chart accordingly.
  • Always try to keep your resting blood pressure near 120/80 . Low salt and low fat diet can help you with that.
  • Make exercise a regular habit. Spare at least 30 minutes daily for that.
  • Keep your weight according to your height. Being overweight increases your risk of kidney disease.
  • Do not smoke / use tobacco.
  • Limit your alcohol intake.

Note: Kidney Disease can result in Kidney Failure, where both kidneys stop functioning, if you don't treat it on time. Kidney Disease can be undone with lifestyle changes and proper treatment. 

Ibuprofen causing Infertility in Men !

Ibuprofen, which is an over-the-counter medicine and commonly used as pain killer around the globe, is recently described as male fertility killer. Decreasing fertility in humans is becoming a topic of concern for scientific community. The latest research was conducted in University of Copenhagen, which suggested that long term usage of Ibuprofen can result in decreased production of male hormone Testosterone. Ibuprofen can reversibly hinder the production of testosterone at both tissue and cellular levels by testicular cells.

An earlier research suggested that aspirin, acetaminophen (also known as paracetamol) and ibuprofen affects the testicles of male babies inside the mother's womb if she is taking them while pregnant. Ibuprofen has the strongest effect, out the above mentioned three medicines. This research inspired researchers in University of Copenhagen to target their research on effect of Ibuprofen on adults. Testicles are not only responsible for sperm production but also for testosterone hormone production. Testosterone is responsible for all manly things in man like muscles and fertility. Ibuprofen is not only used by common man. Athletes and sportsperson also use it as a pain killer, for whom testosterone means a lot.

Shall i totally stop taking Ibuprofen ?
No, the negative effect is only if you take it continuously for longer duration. So if you need to take it for more than three days then you must consult your doctor. A number of other researches will be conducted on the same topic to cross check the results. But still if you have any fear in using it then you may ask your doctor to prescribe some alternate pain killer.

The younger participants in the research who took Ibuprofen for a shorter period, the negative effect can be reversed. But those who are above 40 and taking Ibuprofen for a long time should worry.

Some facts to open your eyes about increasing infertility in human race.

  • 15% of all couples around the globe in 2010 were infertile.
  • Sperm counts of men in North America, Europe, Australia and New Zealand declined by 59% from 1971 to 2011.

Nobody know the exact cause of this increasing infertility. But there is something wrong either with what we eat or what we use to protect ourselves from some diseases. Drugs are often known for their side-effects, which is never mentioned when they are prescribed. Even the manufacturers of these drugs don't print anything about the side effects. Usually medicines are not tested for their effect on the reproductive system of humans. But now the time has come to make some changes. Increasing user awareness can make the difference.
The results of this research has opened the eyes of a number of people as Ibuprofen is the most widely used pain killer around the world.

Record for Highest Blood Pressure

Sometimes some blood pressure machines show such high readings which are not meant to believe. People often recheck their BP again on the same machine to verify it. But the best way is to get it checked on some other machine or get it checked at a medical clinic. Sometimes the BP Machines at home show incorrect readings either due to fault in equipment or incorrect measuring technique. We all know that blood pressure rises whenever we do some physical work. But there is always a limit, up to which your blood pressure will rise. Have you ever wondered about the the highest ever recorded blood pressure of a man or woman.

If you are going to find the record for highest blood pressure then it can be put into two categories.

  • While the subject is in resting position for sometime.
  • While the subject is doing extreme physical work.

Usually the blood pressure is measured in resting position except when you are going through cardio. If you measure the BP of a healthy man, who is running on a treadmill then the readings will be much higher. Usually the upper reading (systolic blood pressure) is affected by exercise. Diastolic BP is usually not affected as it is the pressure on arterial walls when heart is not beating. During exercise systolic BP readings may increase from 120 mmHg to 200 mmHg, and still it is considered normal. Holding your breath during heavy lifting (which is often done by heavy weight lifters) may increase your blood pressure to dangerous levels of 480/350, which can sometimes be life threatening. Regular exercise and endurance training can decrease your resting blood pressure and it may remain lower than normal in daily life.

Maximum Heart Rate (MHR)
MHR = 220 - Age
It means that a 35 year old person can achieve a heart rate of 185 (220-35) while exercising. It is recommended that you should stay between 55% to 85% of your MHR to get best from your exercises. Targeting for your 100% MHR can result is too high blood pressure, which might be risky.

Record for Highest ever Blood Pressure recorded

Resting blood pressure rises only during medical conditions. Rising of diastolic blood pressure is considered more harmful than systolic. Blood pressure level of 180/110 while resting is considered dangerous and medical attention is necessary in such condition. While searching for a record of highest ever blood pressure recorded, we found nothing like that as it is nothing to be proud of. Instead it is a serious medical condition which should be treated as soon as possible with proper medical care. We came across a number of comments on different websites where users told that their BP rose to readings like 234/136. Record levels of blood pressure are often found in patients of stroke and heart attack.
If you ever found any high blood pressure readings, then you may write about it in the comments section below.

Some Medicines cause Acute Kidney Failure

Yes, you heard it right. Some medicines which are used to treat other medical conditions may result in Acute Kidney Failure. If correct treatment is provided at right time then such Acute Kidney Failure is reversible. Some antibiotics, blood pressure medicines, cancer treatment medicines, medical dyes (used in contrast imaging), HIV medicines, nonsteroidal anti-inflammatory drugs, ulcer medicines and some illegal drugs (such as heroin) can cause acute kidney failure.

Some common Acute Kidney Failure symptoms are:
  • Decreased Urine Output
  • Fluid retention, that can cause swelling your legs,ankle and feet.
  • Other symptoms like drowsiness, shortness of breath, fatigue, confusion, nausea and chest pain are also common in some other diseases.
  • Sometimes there are no visible symptoms but only lab tests can detect kidney failure.

25% of Acute Kidney Failure are attributed to medicines used to treat some other disease. If you ever feel some symptoms of mild kidney failure while taking some medication, then you should discuss it with your doctor.
Some common medicines that are known to cause Acute Kidney Failure are:
  • NSAIDS (Nonsteroidal Anti-Inflammatory Drugs) such as ibuprofen, naproxen, Motrin, Aleve, and Advil. They reduce blood flow to kidneys which can cause Acute Kidney Failure.
  • Diuretics, also known as water pills, changes water balance in body and thus interferes with kidney function. Jardiance (empagliflozin) is a diabetes medicine which also have diuretic effect and may cause kidney failure.
  • ACE Inhibitors (such as Lisinopril, Enalaril, and Ramipril) are usually used to treat high blood pressure and heart failure. Names of these medicines usually end with "-il".
  • Chemotherapy medicines used for cancer treatment such as cisplatin, carboplatin, and methotrexate.
  • Some antibiotics cause swelling in kidney and cause kidney failure.
  • Apart from the above mentioned medicines there are numerous others that can cause kidney damage. Some are them are used in treatment of AIDS, cancer, osteoporosis, ulcers and numerous other diseases.

The motive of this article is not mean that you should not take the above listed medicines. Most of the above listed medicines are life saving drugs. But proper usage of these drugs and taking them only on doctor's prescription is necessary if you want to save yourself from any such side effect. Almost all medicines have some side effects associated with them. To save yourself from those side effects it is necessary to take them as prescribed by doctor. You should also keep yourself educated about the medicines you are taking on prescription. Even if you take some vitamin and mineral supplement to keep yourself fit, then you make sure that you know all possible outcomes of that medicine.

How Does Cold Weather affect your Blood Pressure and Heart

There was always a relation between heart diseases and cold weather. Older people often complained about high blood pressure and heart related problems during cold weather. Now new researches have found the reason behind connection between winters and hear diseases. Lower temperature not only chills our body but also make some internal changes in our body, which can be easily overcome by a young healthy adult, but an overweight or older person will find difficulty in coping with that. You will understand the factors responsible for that by the time you reach end of this article.

Effect of cold weather on Blood Pressure

  • Lower temperature narrows the blood vessels and thus blood pressure in increased. It can slightly increase the blood pressure even in healthy human being. 
  • Rise is blood pressure during winters is more common in people above 60. Old age people are more prone to this increase in blood pressure because the elasticity of their blood vessels is very reduced compared to a young person. Narrowing blood vessels during winters and the lower elasticity due to old age results in more increased blood pressure. It puts extra work load on heart.
  • Weight Gain is also common in winters due to reduced physical activity, which can also increase the blood pressure. Not only older people but even young don't want to go outside or doing some physical activity during winters. But our diet is usually increased in winters, which results in increased weight. Increased weight means more body fat, which can also give rise to blood pressure.
  • Those who are already a patient of hypertension, winter brings a more add-on to their blood pressure. So they need to take extra care of their diet and physical activity.
  • Diseases like heart attack and stroke are directly related to blood pressure and heart health. Cases of heart attack and stroke suddenly increase during end of winters. It is because their hearts and blood vessels has taken enough load during winters due to continuous high blood pressure and body weight has also increased during that time.

Precautions necessary to save yourself
To save yourself from the above mentioned negative impacts of cold weather on your blood pressure and heart, you must take some precautionary measures. These measures are must if you are above 60.

  • Wear warm clothes as per the intensity of cold. Proper warmth can save your blood vessels from narrowing.
  • Keep your physical activity  to an optimum level. Heavy weight lifting is also not recommended during extreme winters. Completely abstaining from any regular exercise will also result in increased weight.
  • Balanced diet is also necessary. Keep in mind that your body needs extra food to keep itself warm during winters, but your activity level is also reduced which mean that you will lesser amount of food. So keep these points in mind and decide right amount of food to give you sufficient energy and not letting you increase your weight.
