Autumn and winter is a good season for flu and is prone to cold or sick. But have you noticed that some people seem to have little or no impression of having a cold? How exactly did they do that? Learn the following health care skills, develop good immunity from colds!

Regular movement

According to medical journals, regular exercise habits (e.g. 3 jogging per week) can prevent inflammation and chronic diseases, reduce stress and release stress-related hormones. In addition, exercise improves lymph and blood circulation, enhances immune function and prevents colds, specially during flu season.

Adequate sleep

According to studies, adequate sleep is important for immunity. Studies have found that people who sleep less than 6 hours a night are four times more likely to be infected by the virus than those who sleep seven hours. Studies show that while sleeping, the body releases a protein called cytohormones, which can stimulate the immune system and help the body resist foreign viruses.

Drink less.

Studies have confirmed that drinking can destroy dendritic cells in the human body, which are important cells of the nervous system. After drinking, the body inhibits leukocyte hyperplaemia and also inhibits the transmission of messages on immune system activation, resulting in a decrease in resistance.


Cortisol is a stress hormone that reduces the number of lymphocytes in the immune system and reduces resistance. According to the National Academy of Sciences (NAS), practice yoga or meditation is an effective way to regulate stress and improve overall health.

Vitamin intake

Different colors of fruits and vegetables supplement a variety of nutrients to maintain health and enhance immunity. Vitamin C helps protect against colds or flu, vitamin D also benefits bone health, reduces cardiovascular disease and improves immunity. You can eat egg yolks, mushrooms, salmon, tuna, etc., or add them with nutrients. Choosing D3 can increase the content of vitamin D in the blood, and more sun, so that vitamins can be absorbed twice.

Drink green tea

Green tea is rich in flavonoids and has an antioxidant effect. According to a study published in the journal of the American Nutrition Society (ASN), drinking fresh green tea every day can reduce the risk of blood pressure and cardiovascular disease.

Interact with people

The American Psychological Society has published research that shows that socially isolated people can reduce the body’s immune and healing ability. Experimental studies have also found that non-psychotic patients with loneliness have higher levels of cortisol in their urine than those who are supported or accompanied, and that high levels of cortisol weaken their immunity.

Influenza vaccination

The Disease Control Department of the Ministry of Health and Welfare said that the protective effect of the vaccine will gradually decrease after about six months and recommended regular influenza vaccination. Some populations may be severely allergic to influenza vaccines. It is recommended to confirm the vaccine type before vaccination.

Stay hygienic

Be hygienic in both personal and home environments. Wash your hands diligently and preferably up to 20 seconds. Make sure your hands are clean before dining or touching your nose and nose, preferably with a dry hand when you go out. This is because during the flu season, the influenza virus  can specifically survive for hours in cold and low humidity environments, it is highly likely to be contagious by touch. Although there is only one person in the room, there may be a risk of contagion, so it is recommended to store personal items in your home, such as toothbrushes, towels, cutlery, cups, etc.
