CCTV News: In extreme cold weather, especially when snowstorms occur, we especially remind you to minimize going out and pay attention to prevent cardiovascular and cerebrovascular diseases, respiratory diseases, falls, fractures and other accidental injuries when you go out.

　　Under the stimulation of cold air, blood vessels constrict and blood pressure rises within a short period of time, which causes blood vessels to rupture and cause cerebral hemorrhage.

In winter, there is less drinking water and less exercise, and the blood viscosity increases, which causes cerebral infarction.

Patients with coronary heart disease are prone to angina pectoris and even cause acute myocardial infarction.

People with cardiovascular disease should closely monitor their blood pressure in winter and keep emergency medicine. Patients with high blood pressure should not stop taking antihypertensive drugs at will, and avoid strenuous exercise and mood swings.

　　The elderly have poor lung resistance to cold and are prone to colds and coughs, which can cause severe respiratory diseases.

In winter, the body's heat is mainly lost from the head. According to tests, when the ambient temperature is 15°C, the heat lost from the head accounts for 30% of the body's total heat dissipation.

As the saying goes, "cold grows from under the feet". After the feet are cold, the blood circulation of the whole body will be slowed down, leading to the decline of disease resistance.

For the elderly, the focus is on their heads and feet.

　　Some elderly people with osteoporosis are prone to fractures in winter.

Due to the cold weather, people's limbs are relatively stiff, their joints have poor flexibility, and they are prone to falls.

Elderly people can properly supplement calcium after osteoporosis occurs, usually get up and walk without excessive force, wear non-slip shoes in winter, ensure that the toilet and shower floor are dry, and it is best to turn on a small light after falling asleep at night.

　　When the temperature is low, the warm bath water suddenly arrives from the head, the body will be “unprepared”, causing the head and the whole body skin blood vessels to expand suddenly, a large amount of blood is concentrated on the skin surface, causing the heart, brain and other important organs to become acutely ischemic Dizziness, chest tightness and even angina.

Rinse your feet with hot water before taking a bath, and then slowly pour water on your body after your feet are warm, so that your body has a gradual adaptation process.
