Stroke, which leads to death by clogging or bursting blood vessels that supply blood to the brain, is the fourth leading cause of death in Korea, and it is known that it often comes with cold winds.

If you get out of a warm blanket and get cold air, your blood vessels contract and your blood pressure rises, which can be more dangerous.

In fact, the number of people who died from cerebrovascular disease increased by 24% from 1,800 in July last year to 2,200 in December.

In addition, a 1 degree increase in daily temperature increases the risk of stroke by 2.4%,

The rapid temperature change is considered to be the main factor, as it is large at 2.7% for those over 65 years of age, and there is also a diagnostic study.

If you have paralysis of one limb, sudden speech and visual impairment, dizziness, and severe headaches, you should suspect a stroke.

In particular, even if these symptoms appear and disappear for a while, don't worry and make sure to get a hospital check-up.

The golden time for treatment after stroke is 3-4 hours, and rapid response is paramount, but

don't notice symptoms and can cause more damage.

Moreover, even if you are lucky enough to overcome the crisis, it can cause severe aftereffects such as hemiplegia or speech impairment, causing great pain.
