Got caught in the crossfire! You must be doing the most harmful things in the dog days of summer

This year's dog days begin on July 17, 2016, the fourteenth day of the sixth lunar month in the year of Bingshen.

Starting from yesterday, we officially entered the dog days of summer.

The first dog days of summer is the beginning of the real summer. The first dog days are fixed to be 10 days, starting from the third Geng day after the summer solstice (called the beginning of the dog days).

This year's first dog days of summer are from July 17, 2016 to July 26, 2016.

A folk proverb goes: "The heat is in the dog days, and the cold is in the coldest days." "Fu" means "the heat lurks in the ground," marking the hottest period of the year.

The period of Fu is divided into the first, middle and last period of Fu, which are called the three periods of Fu.

6 things your body fears most during the dog days of summer!

1. The cervical vertebra is most afraid of blowing

The weather is hot and naturally many families turn on the air conditioner for a long time. The cervical spine is exposed to the air conditioner, which will cause diseases in the surrounding soft tissues.

Especially when sleeping at night, the human body is relaxed and the pores all over the body are open. At this time, turning on the air conditioner will cause cold and damp air to enter directly, which is very harmful to our health. It is recommended to turn on the air conditioner about an hour before going to bed to lower the indoor temperature, and turn off the air conditioner when people enter the room to sleep. Repeat this if you wake up due to heat at night. If you really need to sleep with air conditioning, the indoor temperature should not be lower than 25 degrees Celsius, and your shoulders and back should not be facing the air conditioner directly. If the temperature cannot be adjusted by yourself, you can put a shawl on your shoulders.

2. Drinking water too fast

Due to the high temperature, the body will become dehydrated faster, and many people are accustomed to drinking water in large gulps. If you drink water too quickly, the water will quickly enter the blood and be absorbed in the intestines, making the blood thinner and increasing the blood volume. This can cause heart problems, especially for people with coronary heart disease, who will experience symptoms such as chest tightness and shortness of breath. Severe cases may lead to myocardial infarction.

Therefore, you should not drink water too fast in summer, but in small amounts and multiple times. Drink only 100 to 150 ml each time so that the body can absorb it better. Don't drink too much cold water. Warm water above 10 degrees is best for the body.

3 Eyes are most afraid of the sun

Under the scorching sun, eyes are the most vulnerable organs. Experts warn that eyes prefer coolness and fear heat. If you do not pay attention to sun protection, they can easily age prematurely and develop various eye diseases. If you are going out between 10 am and 4 pm, it is best to wear sunglasses, a hat or a parasol. Sunglasses in brown or light green are best for UV protection. You can eat more eye-pleasing foods, such as longan, yam, carrot, red dates, etc. Bacteria multiply quickly in summer, so try to avoid rubbing your eyes with your hands. Washing your face with running water can reduce eye diseases.

The six most harmful things to your health during the dog days of summer! Most people get caught with the first one!

4. The most fearful thing about morning exercise is early

In summer, the sun rises early, and many people go to the park for morning exercises. In the early morning, plants absorb oxygen and exhale large amounts of carbon dioxide after a night of metabolism, which increases the concentration of carbon dioxide in places with many trees, flowers and plants. Studies have shown that in the summer, before 6 a.m., various harmful substances such as nitrogen oxides and hydrocarbons produced by burning coal and automobile exhaust emissions accumulate in the air. This is the peak period of pollution, and breathing this polluted air will have a harmful effect on the human body.

In addition, before sunrise, because there is no photosynthesis, there is not much fresh oxygen near the green plants. Instead, a large amount of carbon dioxide accumulates, which is not good for health. Therefore, morning exercises in summer should not be done earlier than 6 o'clock.

5. The most feared thing at home is dust

The summer is hot and humid, making it easier for dust to attach to the air and enter people's skin and bodies. Because they are difficult to detect with the naked eye, people often neglect to clean them. They float in the air for a long time and attach to the surface of objects in large quantities, becoming a habitat for dust mites and mold spores in the air. These dirt will take the opportunity to enter the respiratory system, causing asthma, rhinitis and other diseases. It is recommended to increase the frequency of cleaning in summer, cleaning every two or three days.

6. The stomach is most afraid of cold

Ice cream, cold drinks and frozen fruits taste so good in summer! However, summer is also the peak season for intestinal diseases. Experts recommend eating less of the above-mentioned cold foods during this season, especially when getting up in the morning and before going to bed at night. In order to keep the "stomach and intestines" warm in time, you may want to add some ginger or mustard when eating cold foods, which can warm the stomach and kill bacteria.
