When the cold dew comes, don't show your legs, keep warm and obey God's will.

After seven o'clock, don't eat, drink more water to prevent cerebral infarction.

It is not appropriate to "freeze in autumn" after cold dew, especially pay attention to the warmth of shoulders, neck, back and feet.

Warm neck: the neck is the main part of cold invasion, which can lead to cough, cold and throat inflammation.

Warm waist: the yang of the elderly is gradually decreasing, which is easy to aggravate the symptoms such as lumbar muscle strain due to cold stimulation. Old people might as well wear a vest when they go out in the morning and evening.

Warm feet: as the saying goes, "cold dew does not show your feet." After the cold dew solar term, you should pay attention to the warmth of your feet, and sandals can basically be put away to prevent "cold from starting from your feet".

Because the foot is farthest from the heart, the blood supply is less, and because the fat layer of the foot is thin, it is particularly vulnerable to cold stimulation. When the feet catch cold, it is particularly easy to cause the capillary contraction of the upper respiratory tract mucosa, which leads to the decline of human resistance. The respiratory tract is extremely sensitive to the stimulation of cold air. Sudden cooling will reduce the resistance of respiratory organs, and pathogenic factors will take advantage of it. It can cause exogenous cough, bronchitis, asthma and other respiratory diseases.

The researchers found that those who ate after 7 pm or within two hours before going to bed were 2.8 times more likely to keep their blood pressure high at night than those who didn't eat.

So after a cold day, try not to eat anything after 7 pm. In addition, patients with hypertension have a high risk of heart disease. If their blood pressure does not drop at night, the risk of heart attack or stroke will be much higher.
