Cold and dizzy.

Zhao Hanyingzi fell down when attending the red carpet event. The cold weather will make people dizzy. First of all, because the human body is stimulated by low temperature, the peripheral blood vessels will contract and the blood pressure will fluctuate greatly. Then there is staying up late for a long time, overworking, decreased physical resistance, and dizziness when the weather is cold.

Zhao Hanyingzi wore a suspender skirt to attend the beautiful ceremony. She looks thin. When she walked on the red carpet, something was wrong with her. Say that finish, zhao from lips pale, seems to be very uncomfortable. Then she fainted to the ground. Some netizens said that he was faking it. In fact, too cold weather can really make people dizzy.

First of all, when the weather gets cold, because the human body is stimulated by low temperature, some people's bodies can't adapt to the changes of the environment, which will lead to the sympathetic nerve excitement and vasoconstriction of patients, and finally the blood is mainly concentrated in large blood vessels, which is easy to cause the blood pressure fluctuation of patients, so some people will have symptoms of dizziness and head swelling. This situation is actually very common in clinic, especially in many patients with hypertension. If their blood pressure is not well controlled in winter, this symptom will appear. If the patient already has cerebral arteriosclerosis, cerebral blood supply insufficiency, cerebral vascular stenosis and other problems, vasoconstriction will also aggravate the phenomenon of cerebral blood supply insufficiency.

Secondly, there is also a situation of dizziness or even fainting when staying up late for a long time, overworking and the environment is getting worse! Because the body's resistance drops, when the weather is cold, it increases the lack of blood supply to the brain and is easy to faint! In this respect, everyone should pay attention not to stay up late at ordinary times, and must rest well, so that the mental state will be good!

In cold weather, when you feel dizzy or faint, you must do ECG, color Doppler echocardiography, head magnetic resonance imaging and brain Doppler examination in time. Everyone should pay attention to keep warm at ordinary times and try not to challenge the limits of their bodies! Especially people with poor physical fitness!
