Seasonal-Change Immunity — Get Ahead of It with Korean Medicine
Table of Contents
Why do we get sick more easily during seasonal changes?
In spring and autumn, the swing between daytime and nighttime temperatures often exceeds 10°C. The autonomic nervous system gets overloaded trying to adapt to these rapid temperature shifts, and immunity drops sharply during this process. That is why colds, rhinitis, and sore throats — upper respiratory infections in general — cluster in these seasons.
How Korean medicine views immunity
In Korean traditional medicine, immunity is called wi-gi (衛氣). It is the defensive energy that circulates over the body's surface and blocks the invasion of external pathogens (邪氣). When wi-gi is weak, even a passing breeze brings on chills, and the smallest trigger sets off a runny nose and sneezing. Korean medicine treatment focuses on strengthening this wi-gi to build a robust immune foundation.
Managing immunity during seasonal change
- Tonic prescriptions: Astragalus, ginseng, and Atractylodes are used to reinforce qi and strengthen wi-gi.
- Acupuncture: Stimulating immunity-related points such as Zusanli (ST36) and Hegu (LI4) enhances natural healing capacity.
- Lifestyle care: Keep the neck and back warm, cut down on cold foods, and get enough sleep.
- Seasonal tonic herbal medicine: Starting 2–3 weeks before the seasonal change gives the strongest preventive benefit.
Immunity is something to prepare in advance
Immunity isn't built up after you fall sick — the key is preparing before illness arrives. If you tend to catch frequent colds or feel run down at every change of season, Korean medicine immune care can help you transition into the new season in good health.
