What Causes Winter Headaches and How Can You Prevent Them
From cluster headaches to winter migraines and even sinus headaches, it may feel like the frequency of all kinds of headaches reaches a new peak during the winter season. We’re often told by elders to keep our head and neck covered during this harsh season – but does this practice have more benefits than just keeping us warm and cosy?
The link between headaches and winters
Research shows that headaches become more common in the winter season as cold temperatures and short sunshine duration can alter the atmospheric (barometric) pressure. This change in pressure can cause haemodynamic (internal blood pressure mechanism) changes in the body, leading to headaches or migraines. Also, the chilly winter winds can constrict the nerves and blood vessels in the brain, which can also lead to headaches.
The sinuses are cavities present on the front side of the skull. They are filled with air and they are in equilibrium with the atmosphere. Any big changes in the atmospheric pressure can disrupt this equilibrium, leading to headaches.
Experts also say that change in the length of the days can be a possible reason behind these seasonal headaches. In the winter season, the duration of nights gets longer and days shorter. That may alter the body’s sleep-wake cycle, giving a rise to headaches.
