The rays of the sun are not as harsh as most people have come to label them. In fact, UV rays can improve health in many ways. They produce vitamin D in the body. They also improve the health of the bones, heart, and the brain. A new study also suggests that UV light can kill off damage-causing bacteria.
Research Shows That UV Light Can Kill Off Harmful Bacteria
Researchers from the University of Oregon conducted an experiment for 90 days to judge the impacts of ultraviolent rays on bacteria. They constructed a miniature model of 11 rooms and planted dust in them to mimic the atmosphere in typical office and house rooms.
When this doll-house was left in open sunlight for approximately three months, the rooms that had no light had 12% of bacteria living and viable whereas those which were exposed to the rays of the sun had almost half that amount of bacteria alive and viable.
The Role Sunlight Plays In Health
The sun’s rays don’t only keep one warm in the colder months of the year. Apart from allowing one to feel cozy, they also promote blood circulation. Certain UV rays are necessary for encouraging the production of vitamin D.
This vitamin is essential for the development of bones, formation of blood cells, strengthening the immune system, and the absorption of phosphorus and calcium. It is said that vitamin D can also cut down the risks of cancer. What’s more UV radiation can help prevent several diseases as well.
These include rickets, eczema, psoriasis, and even jaundice. In old times, sunlight was used for the treatment of the patients of tuberculosis as well. Science says that UV light can help people lead healthier and happier lives. It can also increase one’s lifespan.
UV Light And Bacteria
Did you know that UV light is an anti-infective? Blue light, in particular, can disinfect the environment. UV rays can even disinfect water sans the use of chemicals components. UV light can kill off bacteria, this is a previously established fact as well.
UV light stimulates the production of vitamin D on skin. This vitamin D also has anti-microbial properties. Vitamin D created as a result of sun exposure pushes the production of anti-microbial peptides that can take down the walls of bacteria and viruses.
Over and above that, exposure to the UV rays of the sun can also increase the levels of white blood cells that can destroy infections.
Make sure that you let sunlight inside your rooms by opening the blinds or installing glass walls. Not only will this serve aesthetic purposes, but it will be good for your health as well. It’s obvious that letting bad bacteria thrive does not work in the favor of your health.
Also, avoiding holing up in under the blanket with the curtains closed in winter months. Cover up but allow sunlight in.
