    As colder autumn weather arrives, finding ways of keeping ithe immune system strong has become even more important in a time of coronavirus.

    When the seasons change, the temperature fluctuates considerably from night to day, and the body must try harder to adapt and change apace.

    "The human body always tries to maintain homeostasis, keeping a stable internal environment," said Prof. Choi Cheon-woong at Kyunghee University Hospital at Gangdong. "This requires more energy to allow the organs including the autonomic nervous system to work properly," he added.

    While the body is doing that, the immune system has trouble keeping up. Tests on mice have proved that a lower temperature weakened the immune system and activated tumor cells, according to Prof. Lee Duk-chul at Yonsei University's Severance Hospital.

    Every one degree Celsius increase in the diurnal temperature range was associated with a 0.58-percent increase in mortality, according to a study at Seoul National University Hospital.

    The study showed that the over-65s suffered had a higher mortality rate due to daily temperature fluctuations.

    The body becomes susceptible to infection and disease as cold weather weakens respiratory functions.
