There is sunshine and healing too
There is sunshine and healing too,
Astrophysics experts say that sunlight travels about 93 million miles to reach Earth, which is essential for us, like food, air, and water, while it is estimated that the ozone layer in the Earth’s atmosphere. The sun absorbs about 98% of the radioactive rays, followed by only 2% of the sun’s radiation to the earth’s ultraviolet radiation.
According to a report from the Voice of America, clinicians attribute sun exposure to prolonged cancer prevention, but on the other hand, sunshine is a food for human health and healing too.
Scientists have found that proper sunlight can not only keep high blood pressure moderate but also prevent the risk of heart attacks and stroke.
Researchers at the University of South Hampton have discovered that sunlight changes the level of nitric oxide (gas molecule), a compound in the skin and blood vessels.
Martin Fleish, a researcher, said that a mixture of nitric oxide (NO) is naturally present in our skin in a sufficient quantity to help regulate blood pressure.
Scientists say that the sun causes the skin to release nitric oxide in addition to its broken molecules, with small amounts added to the blood circulation. The NO molecule performs messaging between cells, but one of its important functions is to open the blood vessels, which reduces blood vessels pressure, improves blood circulation and reduces blood pressure and At the same time, the risk of stroke and stroke is reduced.
Regarding cardiovascular disease, Professor Fleish said that high blood pressure and cardiovascular diseases vary depending on the season and latitude, especially in the winter as the disease extends to countries that are far away from the equator and where As the sun’s radiation rays get lower, the number of such cases increases during the winter.
The 24 volunteers included in the study underwent two different experiments of 20 min duration. In the first session, they were exposed to ultraviolet radiation rays and tanning lamps. In the second experiment, participants were only limited to the heat of the lamp.
According to the Journal of Investigation Dermatology, the results showed that sunshine causes the spread of blood vessels, which causes a significant decrease in high blood pressure and changes in the level of NO in blood circulation but vitamin D There is no change in the level of
The levels of NO stored in the upper layers of the skin play a mediator in opening the blood vessels, he said.
Prof. Fleisch said, “Adopting a specific lifestyle in the fear of avoiding sunlight to prevent cancer can increase the risk of heart diseases, while the skin-containing NO is very important for cardiovascular health. Can not be ignored. “
