Cold exposure and dizziness

If you’re exposed to cold weather or intense cold, you may experience dizziness, low blood pressure, and even fainting.

Cold exposure can cause your blood vessels to constrict. This can result in a decrease in blood flow to your extremities.

According to the American College of Cardiology (ACC), it’s likely that these effects are caused by reduced blood supply to your muscles and heart.

You can prevent cold exposure from negatively affecting your health by wearing shoes and socks that are made from a material that’s naturally breathable.

You should also try to avoid direct exposure to cold air, such as on a plane or in a car.
