Unlike countries that experiences 4 seasons, tropical countries have relatively constant hot temperature, rising as high as 34-degrees Celsius. People living in such climate tend to adapt better in hot climate, and are rarely expose to temperature below 24-degrees Celsius. But what if there is a sudden abnormal drop in temperature?

Such phenomenon is due to the monsoon surge in the South China Sea, which result in constant rain and cold air gushing into the country. In Singapore, temperature has fallen, from its typical 27-degree Celsius temperature, to its lowest at 21-degree Celsius, all within days in the beginning of 2018.

What are the health risk in having such sudden drop in temperature?

Rain can indeed help to cool the body down, but an abrupt change in temperature will bring more harm to those living in tropical climate. This is because the body that has been exposed to the same temperature for a long time is now experience fluctuating temperature. This causes the immune system to drop, making them vulnerable to bacteria and viruses. Furthermore, in monsoon periods, such microbes are apparently more active, and they thrive better in contaminated environment (e.g. stagnant water). Together with its contagious nature and the declined in immunity, more people tend to fall ill during the monsoon period. In Singapore, up to 80% of patients in Mount Elizabeth Novena Hospital are experiencing cold-like symptoms. Some common illnesses during the monsoon period includes bacterial infections (E.g. diarrhoea and cholera) and respiratory infections (flu),

How to adapt to the sudden cold weather?

The key to preventing yourself from falling ill when experiencing a sudden drop in temperature is to strengthen your immune system. There are various ways to increase your immunity, such as adopting a healthier lifestyle. Another way to increase your immunity is to consume Vitamin C. Although Vitamin C does not help to cure your cold immediately, it helps to lower the severity of the cold and shorten the time needed for your body to recover. Vitamin C is a powerful antioxidant that builds up the body defense mechanism. When down with a cold, Vitamin C level in our blood is reduced as cell activity increases to fight off infecting organism. Since our body does not produce Vitamin C; it is important to consume it to prevent immune deficiency during abnormal cold temperature. The recommended Vitamin C dosage per day would be at least 70mg (For adults).
