WEATHER HAPPENS TO INCREASE RISK GROWTH RISKS IN ELDERLY FAMILIES

Stroke occurs when blood supply to a part of the brain is suddenly blocked or when a blood vessel in the brain ruptures, causing the blood to overflow into the space surrounding the brain cells.

Observing recent cold weather and statistics at US hospitals, scientists have suggested that there is a connection between weather and the risk of stroke. Cold weather and high humidity increase the risk of stroke

Cold weather, high humidity - factors affecting stroke.

Cold weather, high humidity and large fluctuations in temperature during the day can cause many stroke sufferers to be hospitalized. As the weather gets warmer, particularly if 5-7 degrees increase, the risk of stroke decreases. Judith Lichtman of Yale University and colleagues from many prestigious American universities, including Harvard and Duke, published their study on Feb. 12, 2014, and this is considered to be the most detailed study. Historically, stroke and weather have been linked.

 

Each year about 800,000 American stroke, mostly due to causes of cerebral vascular occlusion and high blood pressure. Previous studies have also found that the rate of stroke tends to be seasonal, and is thought to be related to biological causes. Blood vessels contract when it is cold to raise blood pressure.

 

Extremely cold weather can stimulate the body to release substances that regulate body stress, which force the heart to work harder but make the blood more dense, thus making it easier for the blood to clot. blood vessel.

 

High humidity - increased blood clots and increased pressure on the body.

In addition, high humidity can cause dehydration, which can also increase blood clots and increase the pressure on the body.

 

A number of studies published in 2014 also reported deaths from stroke between 1999 and 2006 and found that deaths in winter were higher during the summer. And one study compared stroke hospitalizations in general (not to mention deaths) and compared them to the daily weather table in some states that detected cold weather, temperature differences During the day and high humidity are related to the number of hospitalizations due to stroke.

 

Every 5 degrees increase in daily temperature fluctuations (taking the highest temperature minus the lowest temperature), the rate of hospitalization due to stroke increased by 6%. And with every 5 degrees increase in the moisture scale, the risk increased by 2%.

 

Heavenly (high humidity) - chronic chronic diseases of the elderly have the opportunity to rise

For the elderly, the weather in Hanoi in the past days is the cause of fatigue, drowsiness, insomnia ... causes headaches, rheumatism, cardiovascular diseases, asthma, pneumonia, dermatitis and radicals. Chronic chronic diseases of the elderly have the opportunity to rise. Not only that, the disease on the skin is leaking out of the sebaceous secretion of non-evaporative sebum produced rash itch, rashes and sores ... Doctor Nguyen Thanh, Central Dermatology Hospital, said when Sun, skin cells outside the skin will dry to reveal layers of young cells so the skin is susceptible to sores, cracks, allergies.

While waiting for the scientists to add new knowledge on this issue, advice to readers is to pay attention to those who are at risk of stroke in the cold, most are elderly, must be careful in eating. Drink and salt intake.

With the sun, many families find the house is wet open the door or open fans to dry. However, according to doctors, this concept is very wrong. The more open the door, the more humid the outside air, the more condensed the water evaporates. The best way to cope is to limit openings, regularly clean the house with a dry towel; Can turn the air conditioner dry. When you see the mold must be cleaned immediately because they grow very fast, easy to cause disease.
