“My body feels heavy for some reason when a typhoon approaches”—that feeling isn’t just in your head
When typhoon season rolls around, more people report “severe headaches” or “feeling sluggish.”
In fact, this phenomenon is caused by the effects of changes in atmospheric pressure on the brain and the autonomic nervous system.
This guide explains the true nature of these pre-typhoon physical discomforts and share practical measures you can take in your daily life.
The Mechanism Behind Typhoons and Air Pressure
Typhoons have low air pressure at their center and move while drawing in the surrounding air.
As a typhoon approaches, air pressure drops rapidly, causing the body to react to this change.
- The inner ear detects changes in atmospheric pressure
- It sends signals to the brain’s autonomic nervous system
- This leads to changes in blood vessel constriction and dilation, as well as hormone secretion
- As a result, headaches, dizziness, and fatigue are more likely to occur
Main Reasons for Headaches and Fatigue
1. Pressure on the Brain Due to Vasodilation
When oxygen levels become slightly lower due to low atmospheric pressure, the brain dilates blood vessels to take in more oxygen.
This vasodilation stimulates nerves, causing migraine-like pain.
2. Disruption of the Autonomic Nervous System Balance
When the switch between the sympathetic and parasympathetic nervous systems doesn’t function properly,
it becomes easier to experience fatigue, drowsiness, and difficulty concentrating.
3. Changes in Brain Hormones
Fluctuations in serotonin levels can lead to low mood and lethargy.
Everyday Precautions to Take Before a Typhoon
- Stay hydrated: This promotes smooth blood flow and helps supply oxygen to the brain
- Consume caffeine in moderation: Its vasoconstrictive effect can help relieve headaches
- Ear massage: Stimulates blood flow to the inner ear and helps alleviate reactions to changes in atmospheric pressure
- Light stretching: Improves blood circulation around the shoulders and neck
- Check weather apps in advance: Monitor the approach of low-pressure systems and adjust your schedule accordingly
Conclusion
Headaches and fatigue before a typhoon are not just “all in your head”—they are
scientifically explainable physical reactions.
Simply knowing about changes in atmospheric pressure in advance and making slight adjustments to your daily routine
may help alleviate these symptoms.
