Take stock of the Four Misunderstandings in summer

In summer, most people take it for granted that everything depends on low temperature. For example, drink ice beer, eat popsicle, blow air conditioner, wear miniskirt, take a cold bath and so on. To do these things, it must be cool for the time being, but there are also many follow-up problems. As a matter of fact, it is not advisable to be greedy for coolness, because often the body breaks down before the summer heat goes away. Follow Sihai Xiaobian.

Misunderstanding 1: short shirts and shorts blowing air conditioning

In summer, when the temperature is high, beauties wear cool clothes. Wearing less clothes outside can reduce sweating, but it is not recommended in air-conditioned rooms.

Many companies have central air conditioning, which is warm in winter and cool in summer. The air conditioning is frozen to goose bumps. They wear shorts and short sleeves to work. They must be equipped with a small coat or blanket in case of emergency.

Without any measures to keep warm, if you wear shorts and short sleeves to blow the air conditioner for a day, the cold will invade your joints and you will easily suffer from "air conditioning legs".

The common symptoms of air-conditioned legs are knee joint pain, knee joint movement inconvenience, joint stiffness after standing or sitting for a long time, squatting difficulty, upper step leg soft, and so on.

If you can't control the temperature of the company's air conditioner, you should keep warm and protect your knees. And timely let the body "escape" air conditioning, people always have to bask in the sun, sweating.

Mistake 2: drink ice beer and eat popsicles

Ice beer is cool, but it doesn't quench thirst! Don't quench your thirst! Don't quench your thirst!

On the contrary, drinking beer will make you feel thirsty. Because the water in beer is not enough to support the oxidation of alcohol, it needs the water in the body to participate in the absorption of water, so it will feel thirsty.

As for popsicles and ice cream, the raw materials are all fats and additives. Eating too much at one time is not only easy to damage the intestines and stomach, causing abdominal pain; it may also stimulate the head nerve, causing headache; moreover, the damage to the teeth is not small.

Myth 3: the fan blows to one part

The most taboo blowing fan to a body part for a long time, especially the head.

If you don't listen, there are two possible consequences--

migraine. I believe many people have this kind of experience.

Stroke. For the elderly with cardiovascular and cerebrovascular diseases, the problem will be more serious, which may induce stroke.

These serious consequences are due to the fact that the electric fan can lower the scalp temperature and cause cerebral vasoconstriction. The lack of cerebral blood flow will lead to a variety of brain diseases.

Myth 4: shower with "100% cold water"

If people who insist on doing exercise every day and have good physical fitness often take cold baths, there may not be any adverse consequences.

Unfortunately, many people are lack of exercise and their physical fitness is not high. If they take a bath with unheated tap water, even in summer, they are likely to catch a cold or damage their muscles and nerves.

Take a cold bath is more particular, the temperature is between 5 ~ 20 ℃, and it is best to take a step-by-step. That is, if the water temperature is high first and then low, and the body is given a time to adapt, it will not cause adverse consequences due to sudden cold stimulation.
