American study: strong light can promote heart health

The integrated care model of heart failure has become a new bright spot of medical care in Taiwan Province Province. The side effects of the new generation of chemotherapy are very low. 90-year-old lung cancer patients have been struggling for half a year. British research: more interaction with people can reduce the risk of dementia. Don't talk at the age of three? These three types of children should pay attention in hot summer. Most people like to stay in air-conditioned rooms and avoid the hot sun outside. But you know what? The heart is not afraid of the sun, I am afraid that you will not bask! Recently, American research pointed out that "strong light" is actually related to heart health, and exposure to strong light can also promote heart health! Although the sunshine in summer is really poisonous, for the sake of health, it is necessary to bask in the sun moderately. Let's see what the study says.

Mouse experiments tell us that sunbathing can repair heart damage.

The editor believes that everyone graduated from Xiamen University and is not afraid of cardiovascular disease at all. They eat delicious food seriously, and they are all obese. However, the Fu Wei Department tells us that about 20,000 people die of heart disease every year in Taiwan Province Province, which is second only to malignant tumor (cancer) among the top ten causes of death, which is frightening. Recently, a study in the United States pointed out that intense light therapy may help reduce tissue damage during heart attack. In this study, mice were tested, and laboratory mice were exposed to strong light for a long time to observe their heart condition. It is found that it can improve the damage of heart tissue and reduce the damage of heart function after heart attack.

Strong light uses two tricks to protect the heart, promote PER2 gene and increase cardiac adenosine

In this study, the researchers found that strong light will affect the function of PER2 gene, and the expression of this gene will be enhanced by strong light treatment. In the experiment, it is found that when the heart tissue of mice encounters hypoxia (such as heart attack), the heart will get extra protection because of PER2 gene strengthening blood vessels, which makes the heart function less damaged.

In addition, strong light can also increase cardiac adenosine, both of which help to protect the health of the heart. In addition, it was determined that the heart condition of mice was affected by strong light, because the researchers found blind mice in the control group to do experiments, and they also worked under strong light, but strong light had no effect on them.

PER2 gene -PER 2 gene originally expressed cardiac adenosine from the brain, which controls the circadian rhythm-a special chemical that helps to regulate blood flow. Blind mouse-a mouse whose eyes can't perceive light. Thanks to the sun, even triglycerides will drop in the sun.

After the mouse experiment, the researchers want to see if it can produce the same effect in human body. The study found healthy participants and exposed them to bright light for five consecutive mornings. After blood drawing, it was found that the content of PER2 in the blood of participants exposed to strong light was higher than the general value. In addition, blood data show that even the triglycerides in the blood have decreased! Therefore, light plays an important role in human health, which can not only regulate the circadian rhythm, but also promote cardiovascular health and metabolism. It turns out that we need sunshine as much as plants.

Strong light can illuminate heart health and is expected to be used in medical treatment in the future.

It used to be "the stars know my heart", but now it is "sunlight illuminates health". This study points out that "light", which seems to have nothing to do with heart health, has an unexpected protective effect and has a positive impact on the treatment of heart disease patients in the future. Researchers say that if phototherapy is performed before high-risk surgery, myocardial injury can be prevented, which also highlights the importance of medical research; In addition, it is also expected to use this research to develop drugs and treatments that can provide similar protection, and further analyze the role of strong light in heart protection.
