Adapt to climate change and increase or decrease clothes in time. Underwear should be soft, moisture-absorbing and breathable, which is conducive to heat preservation and drying, and the outermost clothes should be windproof. Keep shoes and socks warm and dry, and clean them regularly. It is not advisable to sit indoors for a long time, but to do more activities to promote blood circulation in the feet. After scalding your feet with hot water before going to bed, massage your feet with your palm for 10 minutes, which can play a health care role. Modern families should install more heating equipment, and should be properly ventilated to maintain air circulation.

Second, proper exercise.

For patients with coronary heart disease, it is recommended to insist on physical exercise in the afternoon or evening. Outdoor walking, Tai Ji Chuan, Qigong and other aerobic exercises are preferred, and strenuous activities are not allowed. Avoid morning exercises, because early morning is often a high incidence of heart disease events, especially in the cold morning with low temperature, which can cause coronary artery spasm, angina pectoris or myocardial infarction.

Third, a reasonable diet.

In winter, patients with coronary heart disease should advocate a balanced diet, appropriately increase the intake of fruits and vegetables, and reduce the intake of animal oil, sugar, cream and high-fat foods to prevent thrombosis and vascular lumen blockage caused by slow blood flow. In addition, it is not advisable to drink alcohol to keep warm in winter. The fever after drinking is only a temporary illusion. After losing calories, the body is colder, and drinking too much is harmful to the body. Drink in moderation.

Fourth, insist on taking medicine.

In order to prevent the acute attack of coronary heart disease, patients who usually take related drugs must insist on taking them. It is particularly important to prevent thrombosis, lower blood pressure, lower blood lipid and protect cardiovascular system in winter. Many patients do not pay attention to treatment and prevention, such as angina pectoris or heart discomfort, and stop taking medicine as soon as the symptoms are relieved, which is extremely undesirable. In addition, for patients with cardiovascular diseases or risk factors, once they have persistent symptoms such as chest tightness, chest pain or palpitation, they should see a doctor in time.
