Morning exercises are most afraid of getting up early.

Dawn breaks early in summer, and many people go to the park for morning exercises early. However, the air pollutants are the most in summer, and they have not completely spread before 6 am.

In addition, before sunrise, because there is no photosynthesis, there is not much fresh oxygen near the green plants, but a lot of carbon dioxide is accumulated, which is not good for health. Therefore, the morning exercise time in summer should not be earlier than 6 o'clock.

Cervical vertebra is most afraid of blowing

When the cervical vertebra blows against the air conditioner, the surrounding soft tissues will become pathological, leading to chronic inflammation of muscles and subcutaneous tissues, resulting in persistent neck spasm, back pain and other consequences.

Drinking water is the most afraid of being fast.

Because of the high temperature, the speed of water shortage will also accelerate, and many people are used to drinking water in big gulps. If you drink water too fast, the water will quickly enter the blood, be absorbed in the intestine, dilute the blood, increase the blood volume, and have a bad heart. Especially people with coronary heart disease will have chest tightness, shortness of breath and other symptoms, which may seriously lead to myocardial infarction.

My family is most afraid of gray.

Summer is sultry and humid, and dust is more likely to attach to the air and enter people's skin and body. Because it is difficult to be found by naked eyes, people often neglect to clean them up. They float in the air for a long time and attach to the surface of objects in large quantities, becoming the habitat of dust mites and mold spores in the air. These dirty things will take the opportunity to enter the respiratory system, leading to asthma, rhinitis and other diseases.

The stomach is most afraid of cold.

Suggestion: In order to warm the stomach in time, when eating raw and cold food, add ginger or mustard to warm the stomach for sterilization.

These eight habits must be changed in summer.

1. It is unwise to sit on the wood.

As the saying goes, "Don't sit on a stone in winter and a tree in summer." The temperature is high and the humidity is high in summer. Wood, especially wood, chairs and stools placed in the open air for a long time, is exposed to rain and contains more water. When the sun shines and the temperature rises, it will emit damp heat, which makes people susceptible to skin diseases, rheumatism and arthritis.

2. It is not advisable to eat more cold food

In hot summer, if the gastrointestinal tract is stimulated by a large number of cold foods, it will accelerate peristalsis, shorten the residence time of food in the small intestine, and affect the absorption of food nutrition by the human body. At the same time, due to the high temperature in summer, the heat in the body is not easy to dissipate, and the temperature of the gastrointestinal tract is also high. If you are suddenly stimulated by cold, it will lead to gastrointestinal spasm and abdominal pain.

It is not advisable to sleep at night.

In midsummer, sweat glands on the body constantly secrete sweat to radiate heat in the body. After falling asleep, the body is in a relaxed state, and the resistance temporarily drops. At this time, if it is night, the temperature drops and the cold wind strikes again, the body will replenish dew, which will easily lead to headache, abdominal pain, joint discomfort, indigestion and diarrhea.

Lack of siesta is not advisable.

In summer, the days are long and the nights are short, the temperature is high, people's metabolism is vigorous, the consumption is also large, and they are prone to fatigue. Coupled with the hot night, sleep instability, resulting in insufficient sleep. Therefore, taking a nap for an hour or two at noon is good for your health. It can rest various systems of the body and is also a good measure to prevent heatstroke.

5. Don't blow the electric fan for too long.

Blowing the electric fan for too long will destroy the balance of sweating, make people feel headache, dizziness, leg pain, general discomfort, and even induce other diseases in severe cases. It is easier to catch a cold when sleeping with an electric fan on midsummer night. Especially the elderly and children should pay more attention.

6. "rapid cooling"

In hot summer, people often like to take a cold bath to "cool down quickly" in order to sweat and dissipate heat as soon as possible. However, because people absorb a lot of heat in the sun, "rapid cooling" makes the pores of the whole body close quickly, so that the heat cannot be distributed and stays in the body, causing high fever, and it will also cause insufficient blood supply due to the rapid contraction of brain capillaries, which will make people dizzy and even cause shock. At this time, the human body's resistance is reduced, and the cold will "enjoy the cold." So the best way is to dry the sweat on your body first, or wash it after the sweat dissipates.

7. Don't drink in a hurry

Sweating a lot in summer, some people drink a lot of water at once, which will increase the burden on the heart, reduce the blood concentration, and even cause palpitation, shortness of breath and sweating. If you are very thirsty, you should drink a small amount of water first and then drink it later.

8. Do not use drinks instead of boiled water.

Soft drinks, fruit juice, cola and other drinks contain more saccharin and electrolyte. These substances will cause bad stimulation to the stomach, affect digestion and appetite, and if ingested in large quantities, it will also increase the burden of renal filtration and affect renal function. Moreover, excessive intake of sugar will increase human calories and make people obese. Therefore, it is not advisable to drink more drinks in summer. It is best to drink boiled water, especially for children and the elderly. Drink less drinks and drink more water.
