We discuss a lot about how UV light works to eliminate viruses. Our UVC air sanitising units are the latest, cutting edge technology when it comes to home and work safety.
However, today we are going to look into UV light, the sun, and how it affects us.
Small amounts of UV radiation are essential for vitamin D production, so it is important not to be out of the sun for prolonged periods of time.
Too much sun exposure however, can have serious effects on the skin and eyes, and you should learn more about the positive and negative effects of ultraviolet (UV) radiation on the human body.
In order to prevent sunburn, for example, use the forecast to plan your day, keep yourself covered, wear hats and sunglasses, spend time in the shade and use sunscreen with high UVA protection to protect yourself.
It should not be forgotten that UV rays from the winter sun are more harmful because they are absorbed by the diffused sun and reflected by the snow cover.
Sunburn occurs when your skin is exposed to a high level of ultraviolet (UVA) radiation, such as those on sunbeds, and it can have serious long-term health effects.
At first, most people experience mild symptoms such as hot, red skin, but extreme sunburn can be very serious.
Protecting yourself from sunburn is very important because excessive UV radiation directly damages the DNA of skin cells. Not all sun damage is repaired by the body’s immune system, so gradual skin aging and skin cancer can occur over the years.
The incidence of skin cancer in the UK has increased by half (50%) in the last decade and is one of the most common cancers in the UK.
Most skin cancers are caused by UV radiation from the sun or sunbeds, so check the latest information from UV forecasts and see how you can protect yourself from sunburn with NHS advice.
UV radiation has garnered so much attention that there are now talks of using LED wands to increase vitamin D production during winter.
Sunbeds are a Huge Cause of Skin Cancer
UV radiation from sun beds and sunbeds can damage eyes, skin, hair, eyes and other parts of the body and cause cancer.
UV radiation can have positive and negative effects on skin cancer rates in the UK. It is often protected by sunscreen and protective clothing, but we rarely think about what it can do to our eyes.
UV can burn the eye surface, similar to sunburn on the skin, and cause damage to the retina.
When the body is exposed to the sun’s UV radiation, it produces vitamin D, but long-term UV radiation can be more serious. Wear high-quality sunglasses to protect your eyes from UV radiation, and wear sunscreen and protective clothing.
Vitamin D Generation
Vitamin D helps regulate the amount of calcium phosphate in the body that is necessary to keep bones and teeth healthy.
The amount of time you need to spend in the sun and outside to produce enough vitamin D varies from person to person however. People can produce more or less enough vitamin D by spending only a short time in the sun, studies show that it doesn’t take long, about an hour in many cases.
This means that people can take the necessary precautions to protect themselves from burns and reduce their risk of developing skin cancer, while still enjoying the health benefits of sunlight.
It’s Still Dangerous in Winter and Cloudy Days
Even if it is cloudy, it is important to protect yourself, 80% of the UV radiation from the sun penetrates through bright clouds. This can be reflected back and forth between clouds and snow, but at some altitudes there is less atmosphere to filter out the UV rays. The snow can also reflect back into the atmosphere, which can also cause sunburn and skin cancer.
The diffused UV rays reflected by the snow can cause you to be exposed to the same amount of UV light during winter sports. Therefore, it is important to wear polarized sunglasses to reduce the amount of UV light that reaches and damages the eyes by reflecting snow.
UV Impact During Covid 19
COVID-19 is a respiratory disease caused by the SARS-CoV-2 virus and has caused outbreaks worldwide. According to Fisher (2020), SARS-CoV 2 is a new variant of the betacoronavirus family.
Most of these infections are transmitted through direct contact with the infected person’s blood, saliva or other bodily fluids.
The SARS-CoV-2 virus has been specifically tested for its ability to be killed by UV light and hundreds of laboratory studies have shown that ultraviolet light is capable of destroying viruses, bacteria, and fungi.
UV light can be useful for decontaminating surfaces that may be contaminated with the Sars CoV-2 virus by inducing photodimers in the genome of microorganisms.
Some related coronaviruses, including SARS VIRUS, have been shown to be very susceptible to inactivation by UV light.
Several journalistic reports have looked into these studies and provided an assessment of the UV sensitivity and potential impact of ultraviolet (UV) radiation on human health and the environment.
It is estimated that the SARS-CoV-2 virus can survive on the surface for up to 9 days and that it can lead to serious infection in humans within 14 days of exposure.
COVID-19 is highly contagious and residual contamination poses a threat to health care workers and patients as well as the general public.
UV light is used to disinfect surfaces and equipment, but can lead to problems with prolonged exposure to humans.
Staying safe in the sun is incredibly important, but creating enough vitamin d for optimal health is just as serious.
