2. Don't go to bed late and get up early. Winter morning is also considered as the coldest time. If the elderly go outdoors at this time and just run from a warm environment to a cold environment, it will easily lead to colds, and some frail elderly people will easily induce cardiovascular and cerebrovascular diseases such as coronary heart disease.
3. The sunlight exposure time should not be too long. But sometimes you can bask in the sun properly, and it can also promote the body's absorption of calcium and make the body's skin better, which is of great benefit not only to the elderly but also to the young. However, if you are exposed to the sun for too long, there will be negative conditions for a period of time, which will cause harm to the human body, thus making it easier for harmful substances in the air to invade the body and cause trauma or infection. If this continues for a long time, it will also lead to decreased vision and insomnia.
Don't smoke and drink too much. It's very cold in winter. Old people like smoking, chatting and watching TV. As we all know, if smoke is not easy to spread out, it will do great harm to human body. There are also some old people who are addicted to alcohol and get as drunk as a fiddler. Drunk and weak, cold easily invades the body, damaging the heart, lungs and brain.
5. Supplement iron in winter. Heme synthesizes heme in the body to improve the oxygen carrying capacity of blood. Therefore, the oxygen supply to the peripheral tissues of people with iron deficiency will be reduced, and the energy metabolism of human tissues will also be hindered. Insufficient heat production will naturally make people feel cold. Old people should supplement iron in daily life, such as lean meat, fish, animal liver, egg yolk, beans, celery, mushrooms, fungus and so on.
6. Don't take a bath every day. In winter, it is best for the elderly to take a bath every 5-6 days, preferably 5-6 days, and the water temperature should not be too hot. Don't rub your skin hard when taking a bath. It is best to use boric acid soap when taking a bath to reduce skin dehydration. Drink a cup of hot water after taking a bath.
7. Eat more iodine-containing foods. When hypothyroidism occurs in the elderly, it will cause poor local and systemic blood circulation, especially in limbs, which will lead to chills in hands and feet. The synthesis of thyroxine can promote the basic metabolism of human body and also play a role in heat conduction.
8. Don't do strenuous exercise. Physical exercise is a way to promote human health, but the elderly are weak and not suitable for strenuous exercise, so Tai Ji Chuan and other simple exercises are given priority to.
