As late autumn deepens and temperatures gradually drop, this brings less than welcome news for migraine sufferers. The cold weather can easily trigger migraine attacks. Migraine, a common recurrent condition, is highly sensitive to weather changes, and patients should take this seriously.
When cold fronts arrive, the body's response to cold stimuli triggers reflexive cerebral vasospasm, causing blood vessels to constrict. Once constriction reaches a certain threshold, it shifts to passive dilation. This leads to vasodilation, increased blood flow, and enhanced pulsation. The resulting blood flow impacts the pain-sensitive nerve endings on the walls of dilated arteries, ultimately triggering a migraine episode.
To prevent migraine attacks, patients should take the following precautions:
1. Stay warm, especially keeping the head covered. Minimize outdoor time during early morning and evening when temperatures are low. If going out is necessary, wear a hat to maintain head warmth.
2. Avoid prolonged computer or television use.As weather turns colder, many prefer staying indoors, often staring at screens all day. Prolonged screen exposure exposes you to electromagnetic radiation and strains the optic nerves, increasing migraine risk.
3. Maintain a regular schedule, avoid overexertion, sleep on time, and skip late nights. Relaxing activities like hot springs or yoga help reduce migraine frequency.
