Winter work out is better than summer sweat

According to personal trainers and exercise physiologists, the body's primary goal is to maintain stasis, or stability, and that includes keeping a steady temperature. In the cold, the body needs to burn extra fat, to produce energy to heat it back up to the ideal temperature.

Working out in the cold weather can shake off some extra calories. During the winter, the body ramps up its production of a chemical called ATLPL, which helps it to store up fat for the evolutionary scarce season, so staying active in the winter is important to counteracting that.

Working out in the cold makes it difficult for the body to stay warm and burn a ton of calories, the cold acts as a 'thermal stressor,' forcing the body's temperature regulation out of work. To keep the core, vital organs at the right temperature, blood flow to the extremities is reduced, and kept concentrated closer to the heart and internal organs.

The heart rate and metabolism slow, trying to save up energy and keep the warm blood in place. That's when the shivering starts. Those shakes are a series of fast muscle contractions and releases, a way for the body to produce some extra warmth by burning energy stored in fat.

When you get into a relatively consistent, high intensity workout - though you'll feel like you're working harder at first, against your slower heart rate and metabolism - the body begins warming up from more robust fat burning. As your heart rate rises, blood and warmth return to your hands, feet and other extremities, and shivering is no longer necessary.

Once you hit that point, you're burning calories as you would during exercise at any temperature. During the winter, the body crave extra simple carbohydrates found in sugary foods like baked goods and get vitamin D deficient spending too much time indoors. Getting some winter sun will boost your vitamin D to break those sweet indulgences.

Walking in moderately warm clothing on a cold day will keep the heart rate from getting high enough to cancel out the shivers, but enough activity is require for burning some fat for energy. Body temperature will be  lower when you are closer to the cold while playing in the snow, making the body ready to fight to stay warm.

Cold weather increases heart failure

Hospitalization and death in elderly patients with heart failure could be associated with changes in temperature and atmospheric pressure. Elderly with heart failure should avoid fog and low cloud in the winter to prevent heart failure. Weather changes can affect the health of vulnerable people; heat waves and cold spells have been shown to increase disease and even lead to death in some people.

Researchers assessed some people aged 65 years and older that had been diagnosed with heart failure. The participants were followed for two years. During this time, the researchers measured the mean temperature, relative humidity, atmospheric pressure and air pollutants in the surrounding environment and studied the data to see if there was an association.

The results showed a higher risk of hospitalization or death in the winter period of the year compared to the summer period, they also found that the risk of heart failure incident increased with increase in atmospheric pressure.
A drop of 10°C in the average temperature over seven days, which is common in several countries because of seasonal variations, is associated with an increased risk in being hospitalized or dying of heart failure of about 7 percent in people aged over 65 diagnosed with the disease.

 The study suggests that exposure to cold or high-pressure weather could trigger events leading to hospitalization or death in heart failure patients. This means that they should avoid exposure to fog and low cloud weather in winter as they often accompany high pressure.
The study reveals the impact of changes in temperature and air pressure on heart failure patients. Exposure to cold or high-pressure weather could trigger events leading to hospitalization or death in heart failure patients.

Common cold cure

Common colds are mild viral infections of the nose, throat, sinuses and upper airways. Researchers from the University of Helsinki have revealed zinc acetate lozenges could increase the rate of recovery from a cold.

Colds often strike in winter, main symptoms are sore throat, a blocked or
runny nose, sneezing and a cough.
There is no immediate cure for the condition, but the NHS recommends staying home and resting, drinking plenty of fluids and eating healthily as the top ways to treat it.

The scientists analysed three patient trials with in which 80 to 91 mg/day of elemental zinc were administered as zinc acetate lozenges to 199 common cold patients.

The results found patients who were given the lozenges recovered faster.
Experts said the effect was not modified by age, sex, race, allergy, smoking or severity of the common cold.

The researchers said: “On the fifth day, 70 per cent of the zinc patients had recovered compared with 27 per cent of the placebo patients.

Colds spread by touching an object or surface contaminated by infected droplets and then touching your mouth, nose or eyes, touching the skin of someone who has the infected droplets on their skin and then touching your mouth, nose or eyes.

Warm planet may increase diabetes

Global warming is increase in temperature of the earth surface, warm temperature will deactivate the use of brown fat in the body.

Diabetes occurs when the amount of sugar in the blood is too much because the body cannot use it properly.

If the global warming continues it may increase diabetes by making brown cell inactive for a long period of time.

Brown fat is very active in winter, when the temperature is cold. People with type 2 diabetes can be expose to cold regularly to improve the use of insulin. It can also leads to production of new brown fat cells in the body.
