People who don t exercise and have cold skin is what is the disease

Blood circulation is too slow, resulting in cold hands and feet.

It is the largest heat dissipation organ, and it takes away some of the heat after sweating, so it will feel very cool, which is a normal physiological phenomenon.

Precautions for summer sports.

a.Definitely drink plenty of water.

During exercise, it is recommended to supplement 100C-200C of water every half an hour, but in the face of summer like a powerful dehydrator, it is recommended to increase the hydration, and drink more water. Don't worry about drinking too much water and getting too heavy to run, because your body digests water faster. Moreover, in terms of health, drinking too much water is much healthier than being dehydrated.

b.Vaseline should be applied firmly.

In summer, oily Vaseline will gradually lose its lubricating effect with sweat, and soon, runners' armpits, groins, toes, etc. will begin to rub. When you run long distances, you will find bright white sun-dried salt particles on your arms, and the friction of those tiny particles around the rest of your body is much worse than you think.

c.Don't train every day.

Unless your main event is a hot Badwater Marathon or a Sahara Marathon, don't practice long distances or energy-burning interval speed training in the middle of the day. First, excessive physical exertion may lead to irreversible damage; Second, the high temperature will slow down the running speed, so that the effect of speed training is half the effort.

d.Take sun protection measures.

Wear sunscreen and try to wear light-colored clothing. SPF recommends 30 or more to effectively block UV rays. Dark-colored clothes absorb heat quickly, while light-colored clothes absorb heat slowly, so you may have completed your summer training before the heat has even attached to your clothes.

Also, remember to wear a hat or sunglasses. In addition to **, also remember to protect your eyes.

First of all, most of this situation is because when people are hot, blood vessels dilate, sweat gland secretion increases, sweating more, and a large amount of sweat evaporates, taking away the heat.

Secondly, there are two ways to sweat to cool down, one is to sweat a lot to take away the heat; One is to cool down by evaporating sweat.

Evaporation of sweat is the most effective way to cool down, and when sweat evaporates, the temperature is sometimes slightly lower than body temperature, so that people will feel cold.

On the other hand, if you exercise a little, you will sweat profusely. Traditional Chinese medicine believes that it is caused by "insufficient lung qi and weak Weiyang". **It should be based on the principle of "nourishing the lungs and invigorating qi, consolidating the surface and nourishing yin".

You can choose to take Buzhong Yiqi Pills, Shengmai Drink to cultivate Tusheng Jin, invigorate Qi and sweat, or chew American ginseng, ginseng, etc., and you can also choose to add or subtract Shengmaisan and Yuping Pills.
