Why Are Strokes More Common in Winter?

Oct 01, 2022

Incidences of strokes show a slight spike and worse outcomes in winter than in the warmer months. The reason for the spike in stroke incidences in winter is not entirely apparent to the medical fraternity. However, some researchers mention some potential factors that might explain the reasons for the spike.

Seasonal Stroke

Research from countries like the US, Australia, Germany, Finland, and Iran all report stroke incidences increase during colder months than in warm climates. However, seasonal strokes showed a marked absence in India, showing no changes in any weather or season. The difference in stroke incidences in India is related to warmer winters and more consistent temperatures throughout the other months than patients having a seasonal stroke spike.

Causes for Seasonal Strokes

The causes of seasonal incidences of strokes are largely preventable. However, the reasons for the higher number of strokes in winter are the increased frequency of infections, lack of sunlight, depression, indoor lifestyle, and insufficient exercise.

Strokes from arterial defibrillation also increase stroke risks during the winter, although the association’s reasons are unknown.


Research reveals that some severe infections can increase the risk of a stroke to need prompt attention from the emergency room near me to prevent severe complications. The emergency room might suggest infection prevention to help decrease your risk of strokes. An excellent way to reduce your chances of strokes is to receive the recommended immunizations for infections like the flu that help minimize hospitalization.

Indoor Lifestyle and Insufficient Exercise

Lake Jackson emergency room recommends getting outdoors out of cooped places as beneficial to protect you from germs contributing to infections. Taking a brisk walk is recommended in moderately cold weather because it is helpful for the heart. In reality, exercise is excellent for boosting your immune system.

When you exercise and increase physical activity during the winter, it functions as valuable to stay healthy. Exercising also helps reduce high blood pressure and LDL cholesterol while increasing HDL cholesterol.


The lack of exposure to sunlight, physical activity, and inability to get outdoors all contribute to seasonal depression in winter, which increases the risk factor of strokes in winter with worse outcomes. Recognizing you have depression is essential to receive treatment from a freestanding ER to ensure you don’t become a victim of a stroke. Some people might benefit from cognitive strategies to help reduce winter depression. However, others might need intervention from counselors or medication for this condition.

Lack of Sunlight

The possibility of a stroke increases significantly from the lack of sunlight and depression. During winter, vitamin D deficiency is common and is associated with depression and seasonal affective disorder. Depending on the weather circumstances in your geographical location, you can consider going on a vacation to get more sunlight or alternatively invest in seasonal affective disorder emit light that helps reduce symptoms of winter depression if vacations are not an option.

Reports also claim that the higher incidences of strokes in winter result from constricted blood vessels that increase blood pressure. However, researchers have also discovered that blood thickens during extreme cold, making it easier to clot. Strokes occur due to blood clotting blocking tiny blood vessels in the brain. In addition, the body reacts to cold weather by putting additional stress on the heart as people clamp down for heat and energy preservation.

In addition, humidity also plays a role in the risk of strokes. High atmospheric humidity causes people to become dehydrated to increase the risk of blood clot formation. Therefore while strokes in winter show a spike, temporary incidences have also been observed in July.

If you are at risk of a stroke and living in an area with a colder climate, you must ensure you remain healthy by getting sufficient exercise and preventing issues like seasonal depression, infections, or the lack of sunlight. In addition, you can evaluate yourself for the risks by visiting your physician or the nearest urgent care, where you receive prompt attention from medical professionals working round-the-clock to help you determine how to reduce your chances of strokes in winter.
