Dizziness in hot and cold weather.

Analysis of illness: The symptoms of dizziness appear when the weather is a little cold, mainly because the body can't adapt well to the changes in the environment. When it is cold, the sympathetic nerves of the body will get excited and contract blood vessels. When atherosclerosis occurs in the blood vessels of the brain, there will be insufficient blood supply to the brain and dizziness.

In addition, blood pressure needs to be measured. When the weather is cold and the communication nerve is excited, the blood pressure will rise, so it is ruled out whether dizziness is caused by the increase of blood pressure.
