World Stroke Day 2022: When a blood artery in the brain bursts and bleeds or the blood supply to the brain is cut off, it can result in a dangerous health condition called a brain stroke. This blockage obstructs the flow of blood and oxygen to the brain tissue. Due to lack of oxygen, brain tissue and cells are damaged and die every minute. A stroke can cause permanent brain damage or death if it is not recognized in time.
Stroke has emerged as a major global health concern. Acute ischemic stroke, commonly known as a “brain attack”, is a medical emergency that requires immediate attention to prevent disability and death.
What role does weather play during a stroke?
Evidence suggests that the risk of stroke is increased in cold weather. Cold weather causes blood vessels to constrict, which can increase blood pressure and increase the risk of stroke.
However, experts have also established that during extremely low temperatures, blood thickens and becomes viscous, making it easier to clot. A blood clot that blocks a blood vessel to the brain is the most common cause of stroke. When we are “comfortable” in cold weather to conserve heat and energy, our body’s response often puts the heart under additional stress.
seasonal change
Humidity also plays a role in our stroke risk. Some individuals can become dehydrated due to the high humidity of the environment, which increases the chances of blood clots forming. Overall, it has been found that there is a seasonal trend in stroke rates—strokes are higher in winter and less in summer, with a slight increase in July.
Common stroke symptoms are:
– severe headache
– Numbness in one part/side of the body, especially in the face, legs and body.
– paralysis
– Trouble speaking or understanding speech
– loss of vision, and sometimes the vision is dark and blurry
– Nausea and vomiting Unsteady in maintaining body balance Difficulty walking
– dizzy
