Precautions for elderly people living alone:

1, the best time to bask in the sun

8 am to 10, and 4 pm to 7 pm is the best time to bask in the sun. At this time, the sunlight is mainly the beneficial ultraviolet A beam, which can make the human body produce vitamin D, thus enhancing the anti-tuberculosis and osteoporosis prevention ability of the human immune system and reducing the incidence of arteriosclerosis.

2, the best time for beauty

The skin's metabolism is the most vigorous from 24: 00 to 6: 00 the next morning, so it is best to use beauty and skin care cosmetics before going to bed at night, which can promote metabolism and protect skin health.

3. The best time to brush your teeth

Three minutes after a meal is the best time to rinse your mouth and brush your teeth. Because oral bacteria begin to decompose food residues at this time, the acidic substances produced by them are easy to corrode and dissolve enamel and damage teeth.

4. The best time to drink tea

The best time to drink tea is after eating 1 hour. Many people like to drink hot tea immediately after meals, which is very unscientific. Because tannic acid in tea can combine with iron in food to form insoluble iron salt, which interferes with the absorption of iron by human body and can induce anemia over time.
