Positive and Negative Effects of UV Rays

Many of us enjoy the sun’s warm rays, especially in the summertime. We like to sit outside by the pool and soak up the sunshine, and enjoy it in the morning when it streams in through the blinds. However, we also know that the UV rays can be damaging, especially to our skin. Window tinting in Birmingham, AL can help mitigate some of the damages that UV rays can do, even through your windows. However, there are some positive effects as well. Read on to learn more about the good and the bad of UV rays.

Benefits of UV rays

You’ve probably felt the mood boost that comes along with the sunshine of spring and summer. Sunlight stimulates the pineal gland in the brain, which produces chemicals called tryptamines. These chemicals improve our mood substantially. Plus, our bodies use UV light from the sun to produce vitamin D, which helps strengthen bones, muscles and the immune system. It can also help lower the risk of some types of cancer, such as colon cancer, which is ironic since UV rays are also known to be the leading cause of skin cancer. However, the skin can gain some benefits from UV rays as well. In the case of psoriasis, exposure to UV rays will slow the growth of skin cells that shed too quickly and help relieve symptoms.

In addition to our bodies, UV rays have benefits for the rest of the planet. It helps many animals’ vision and navigation. For instance, birds and bees can see into the near UV light to locate ripe fruits and flowers. These ripe fruits and flowers stand out more strongly from the background and appear differently from how we see them. There are different line markings visible in UV light that can help direct bees to nectar. Plus, insects use UV emissions from celestial objects to help with navigation in flight. Additionally, UV can be used to kill microorganisms such as viruses and bacteria, and has disinfectant qualities, which is why hanging clothes on a clothesline is a great way to ensure they’re clean.

Negative effects of UV rays

The most obvious negative consequence of UV exposure is skin cancer. In fact, UV rays are the most prominent carcinogen in the environment. It also causes sunburn and damage to skin cells when they absorb too much energy from UV rays. Plus, it can damage the immune system. In fact, a sunburn can change the distribution and function of the white blood cells for up to 24 hours after exposure. When the eyes are exposed, UV rays can burn their surface, causing snow blindness and prolonged damage like cataracts. It speeds up skin aging, causing sun spots and wrinkles. In your home, it may fade your furniture and other belongings due to dyes absorbing UV light and changing colors.

Like many things in life, it’s best to mitigate sun exposure and find a balance between good and bad effects. Since the bad effects can be so serious, it’s especially important to be protected where you spend the bulk of your time: indoors.
