What do you need to pay attention to in the middle of the dog days?

1, middle cervical vertebra is most afraid of blowing.

The weather is hot and natural. Many families leave the air conditioner on for a long time, and the cervical vertebra blows against the air conditioner, which will cause pathological changes in the surrounding soft tissues, forming chronic inflammation of muscles and subcutaneous tissues, resulting in persistent neck spasm, back pain and other consequences. It is suggested that the indoor air conditioning temperature should not be lower than 25 degrees Celsius, and the shoulder and back should not be directly facing the air conditioning. If the temperature cannot be adjusted by itself, you can put a shawl on your shoulder and take a hot bath at night.

2, drinking water in the middle 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, water will quickly enter the blood and be absorbed in the intestine, which will dilute the blood, increase the blood volume and make the heart bad. Especially people with coronary heart disease will have chest tightness, shortness of breath and other symptoms, which may seriously lead to myocardial infarction. Therefore, drinking water in summer should not be too fast, but should be done in small quantities many times. Drink only 100~ 150 ml each time, and your body will absorb it better, and you can't be greedy for cold. Warm water above 10 degree is the best for your body.

3, the eyes in the middle are most afraid of sun exposure
