Five misunderstandings of cooling and relieving summer heat in summer

Summer, cooling off the heat? It is the topic that people are most concerned about. Here I will introduce five misunderstandings about cooling in summer, and welcome everyone to read.

Five misunderstandings of cooling and relieving summer heat in summer 1. It is unscientific to bathe in cold water.

In hot summer, the surface temperature reaches 40-50 degrees. If you can take a cold bath, it is undoubtedly the most comfortable for those who exercise outside, but you don't want to. This way is not desirable. Taking a cold bath can cool the body and relieve the heat, but it is very harmful to the body. Taking a cold bath is very easy to hurt blood vessels and cervical vertebrae.

Because in summer, blood flows much faster than at other times. At this time, the blood vessels of the body are constantly relaxed. If you stimulate them with cold water and water them with cold water, the blood vessels in the body will contract immediately, and the blood in this blood is still flowing rapidly, which will increase the pressure on the blood vessels. When the blood vessel contracts too much and cannot fully support the pressure of this blood vessel, there will be the danger of blood vessel rupture and even life-threatening.

For people in poor health, after taking a cold shower, there may be limited neck movement and numbness in hands and feet. On the other hand, when they first get home, it is best not to face the air conditioner, which will also affect the blood flow in the body. Therefore, it is suggested that those friends who exercise a lot in summer and want to cool down with cold water in summer should never take a bath with a whole basin of water. If they like taking cold showers too much, the best way is to wipe their bodies with wet towels to completely cool them down, so as to achieve the effect of slow blood flow.

Second, it is unacceptable to sleep on the floor.

Summer nights are often too hot to sleep. At this time, if you can make a floor, spread a mat and sleep on the ground, it is undoubtedly the coolest, but you don't want to. This way of cooling off summer heat is absolutely unacceptable.

When enjoying the cool in summer, it is best not to lay the floor under the eaves or in the aisles, but to stay away from the gaps in the wind windows. The purpose of this is to prevent the wind from invading the human body through the gap, thus causing yin-summer syndrome. Moreover, it is not good to sleep and gluttony at this time, which will have a yin-damaging effect on the body and greatly damage the yang in the body.

Therefore, if the weather is too hot to sleep in summer, you can open the window for ventilation after getting up every morning and close the window before going to work. In this way, the bad indoor air is discharged at night, and the fresh air outside is supplemented. On the other hand, it is to prevent direct sunlight and turn the room into a stove. Therefore, before going to bed at night, you can try to adjust the air conditioner to about 27 degrees, open the doors of all rooms in your home, and ventilate each other to create a cool environment, which is conducive to sleep.

Third, drinking tea on an empty stomach hurts the stomach.

Drinking a cup of cold boiled water in summer is undoubtedly the most comfortable, and it is even better for those office workers to drink a cup of herbal tea. Actually, it's not. Drinking tea in summer is really a very good way to relieve summer heat, and for those office workers, tea can play a refreshing role.

However, when drinking tea and water in summer, we should pay attention to several points. First, try not to drink tea water on an empty stomach, because at this time, the active substances in tea will be mixed with protein in the stomach, which will cause certain harm to the human stomach. On the other hand, drinking tea on an empty stomach will dilute the digestive juice of the body and affect the digestive function of the body; Secondly, when drinking tea water on an empty stomach, some substances in tea will be absorbed by the human body, such as caffeine in tea. Excessive intake is not good for the body, which will cause palpitation, dizziness, weakness of hands and feet and so on. This phenomenon is also called? Tea? .

Fourth, eat less cold drinks in summer.

In summer, it is undoubtedly the most comfortable if you can eat cold drinks. The cool feeling makes you feel what is the real summer artifact in this hot summer, but you don't want to eat less cold drinks and other foods.

First of all, eating a lot of cold drinks will make the gastrointestinal function unable to work normally. A large number of cold drinks will interfere with the normal peristalsis of the stomach, directly affect the digestive function of the body, cause indigestion, affect the slow blood supply of the stomach, and greatly reduce the self-repair function of the stomach.

Drinking cold drinks for a long time can induce abdominal pain, especially for friends with coronary heart disease and angina pectoris. Eating a lot of cold drinks will lead to vasoconstriction in the body, which will lead to the increase of blood pressure and the acceleration of arterial contraction, which will lead to angina pectoris. In severe cases, coma will occur, which is harmful to health.

Although light food is good, it is more effective to eat it comprehensively.

When eating in summer, we usually choose to eat some light food, which is very good for our health and can also prevent getting angry. However, because of the high consumption of body calories in summer, we don't want to make a comprehensive supplement in our diet.

For those friends who do a lot of exercise, it is essential to eat some high-calorie food in summer, and enough calories can supplement enough energy for the human body. But for some friends who are weak, it is very easy to get heatstroke in summer. At this time, we should eat more light food. Of course, every meal can't be light vegetarian. In due course, you can eat some fish and aquatic products, and supplement eggs and milk from protein.

Therefore, it is not appropriate to blindly eat light food in summer, but blindly eating high-calorie food is not good for your health. Therefore, in summer, we will eat more light food and some meat food with high nutritional value, which is very helpful for the supplement of body nutrition and the supply of comprehensive nutrition.
