After people enter old age, the functions of various parts of the body gradually decline, so we must pay attention to health preservation at this age, so there are four golden periods of health preservation, which should not be missed.

The first golden period of health care is to brush your teeth about half an hour after meals, because the teeth of the elderly will become loose because of calcium deficiency, so you can brush your teeth 30 minutes after meals. For example, if you eat some acidic food while eating, your enamel will be softer.

If you are not careful, it is easy to corrode your teeth. After a long time, it will cause gum allergy and teeth will be sour when eating. But you must choose a soft toothbrush and use fluoride toothpaste, so as to make your teeth strong.

The second golden period of health preservation is an hour's walk after meals. Walking after meals can promote the digestive function of the stomach and improve the blood circulation of the body, which is very important for the elderly. But when you walk, you should control the time, and it will take about half an hour. Don't be too anxious when you walk. You can walk slowly and choose a smooth road.

The third golden period of health care is to soak your feet at 9 pm, which can relax your body and relieve the pressure in your later years. The fourth golden period of health preservation is to take a hot bath about 90 minutes before going to bed, which can improve the anxiety symptoms of the elderly when they sleep and prevent cardiovascular diseases.
