How high humidity causes ‘damp’ illnesses, plus TCM experts’ tips to safeguard your health


Hong Kong is steeling itself for the muggy weather that typically envelops the city as summer approaches, with April and May usually the most humid months in the city.

Traditional Chinese medicine (TCM) holds that high humidity gives rise to “external dampness”, which can invade the body, putting strain on certain organs.

This may cause ailments including diarrhoea, headaches and dizziness. It can also trigger sore muscles and bones, and joint pain.

People with chronic diseases such as eczema and rheumatism should bear in mind that these conditions can worsen in humid weather.

According to TCM, the spleen and stomach are responsible for processing and discharging “dampness” from the body. Accordingly, humid weather can lead to poor digestion.
