The so-called optimal time refers to the most suitable and beneficial time to do certain activities for health. Did you know that there’s an optimal time for everyday activities?
The best time for rinsing and brushing teeth is 3 minutes after meals. This is because oral bacteria begin to break down food residues at this time, producing acidic substances that can corrode and dissolve tooth enamel, causing damage to the teeth.
The best time for drinking tea is 1 hour after meals. Many people like to drink hot tea immediately after meals, which is not very scientific. This is because tannic acid in tea can combine with iron in food to form insoluble iron salts, interfering with the absorption of iron by the body. Prolonged consumption can lead to anemia.
The best time for drinking milk is before bedtime, especially for middle-aged and elderly people. It can compensate for the low blood calcium level during the night and protect the bones. Additionally, milk has a sedative effect.
The best time for eating fruit is 1 hour before meals. Since fruits are considered raw food, eating them before cooked food prevents an increase in white blood cells in the body, which is beneficial for protecting the immune system.
The best time for sun exposure is from 8 am to 10 am and from 4 pm to 7 pm. During these times, sunlight primarily consists of beneficial UV-A rays, which can stimulate the production of vitamin D in the body, thereby enhancing the immune system’s ability to fight tuberculosis and prevent osteoporosis, as well as reducing the incidence of arteriosclerosis.
