The Hypothalamus and Seasonal Patterns

A large proportion of cluster headache patients report that their cluster periods begin during the spring or autumn transition, or around the times when daylight is at its longest or shortest. The hypothalamus regulates the secretion of melatonin and serotonin according to the amount of daylight, and when this rhythm is disturbed, repeated over-activation of the trigeminal nerve can occur.

Korean Medicine Clinic Perspective — Climate Change and Liver-Qi Stagnation

At Dongjedang, we observe that Liver-Qi stagnation (gangi-ulgyeol) tends to worsen during seasonal transitions. As climate change increases the burden of the body's adaptation, the liver's free-coursing function becomes further suppressed, making it easy for fire (hwa) to accumulate. This is why we recommend pre-emptive treatment before a cluster period begins.
