New study findings Night-time ‘light pollution’ may increase the risk of Stroke is on the rise and up to 80% of people will suffer from it.
- Research has found that people exposed to “artificial light“it’s too bright. Being outdoors at night increases the risk by 43%.Hit Stroke and other conditions that affect blood flow to the brain Compared to people exposed to low light
- Studies indicate that approximately 80% of the world’s population lives in environments with light pollution. It also inhibits production.Melatonin affect sleep
- Those who come into contact with “air pollution“Burning petrol, diesel or wood increases the risk of having a stroke by 41%. Those exposed to dust or smoke had a 50% increased risk.

Night lights help humans travel safely at night. But nowadays there are many different types of lights outside buildings at night. In addition to lighting There are also lights that decorate the building. traffic light Including the lights of various advertising signs. which has become more and more common until it becomes “light pollution” which poses many health risks. One of them is Risk of having a stroke
The study, published in the American Heart Association’s journal Stroke, looked at people living in the city of Ningbo. industrial port city in China, home to 28,302 people, researchers found
Those who come into contact with “artificial light“it’s too bright. Being outdoors at night increases the risk of stroke and other conditions that affect blood flow to the brain by 43 percent. Compared to people exposed to little light
The researchers say so. Their study is one of the first. which explores the relationship between nighttime light and brain health
“Our study suggests that exposure to higher levels of outdoor artificial light at night may be a risk factor for stroke,” said Dr. Wang Jiangbing, a researcher at the Department of Public Health. and endocrinology at the Children’s Hospital School of Medicine of Zhejiang University said one of the study’s co-authors.
80% of people live in environments where “Light pollution”
Previously, scientists around the world were worried about “light pollution” more because of the light coming from buildings at night. It began to affect the visibility of stars in the sky. It also affects health.Biological clock in humansThis new study supports this fact.
Studies indicate that approximately 80% of the world’s population lives in environments with light pollution. Through continuous exposure to artificial light at night, such as LED bulbs or fluorescent bulbs. It can inhibit productionMelatonin which is a hormone that promotes sleep
The hormone melatonin is normally released by the body at night. make you feel sleepy But at night there is artificial light as bright as daylight. The result will be that the body will not secrete melatonin. The body is easily alert. Furthermore, when the body lacks red light, obesity occurs. And there has been a significant increase in people with diabetes.
Research also shows that people with problemschronic sleep Greater likelihood of developing cardiovascular disease over time. The study found that there were 1,278 cases of stroke, 777 cases of ischemic stroke, which is the most common type of stroke. He has a blood clot that is blocking blood flow to his brain.
Dr Wang said people living in urban areas should reduce their exposure to light pollution. to protect yourself at least Refrain from using your smartphone Or try the LED light for half an hour before going to bed.
Relative content
Air pollution increases the risk of stroke.
The study also looked at air pollution levels, finding that people exposed to “air pollution“Burning petrol, diesel or wood increases the risk of having a stroke by 41%.
while those exposed to the highest levels of air pollution From inhaling PM10 dust, coarse dust particles Those exposed to the highest levels of nitrogen oxide from vehicles and power plants had a 31% higher risk of stroke than those exposed to the highest levels of nitrogen oxide from vehicles and power plants.
“Even today we manage to reduce the risk of heart disease. and cardiovascular health, such as smoking, obesity and type 2 diabetes, but it is also important to consider environmental factors to reduce the global burden of cardiovascular disease,” Wang said.
However, this study was based on a single city population. Therefore, these findings may not be applicable to people from other communities. The author said Other limitations include a lack of information on indoor lighting products or light-blocking measures such as blackout curtains.
“We need to develop more effective prevention policies and strategies. Reduce the burden of disease resulting from environmental factors such as light and air pollution. Especially for those who live in the area. densely populated AND there is pollution all over the world,” Wang said.
