Surprising Health Benefits of Sunlight Exposure

Your quickest pick-me-up and health booster may not always come from a bottle. If you live in the part of the world where sunlight is available year round, you are already getting it for free. Aside from enabling people to generate their Sun and your skinown vitamin D, here are daytime exposure’s leading health benefits, some of which you may not have heard of yet.

Lowers Blood Pressure Level

Each year, 30 percent of deaths worldwide can be attributed to cardiovascular disease, which is usually linked to high blood pressure. The good news is that blood pressure may be reduced and risk for heart disease may be lowered when skin is exposed to sunlight, according to researchers from the University of Southampton and University of Edinburgh. In a study published in the Journal of Investigative Dermatology, it is shown that when nitric oxide (NO) and its byproducts–which are present in human skin and are known to be associated with regulating blood pressure–are exposed to the sun, some of the NO on the skin gets into the circulatory system, thus effectively dilating the blood vessels and lowering blood pressure. And even as the blood pressure is significantly reduced through NO’s impact on the blood vessels, vitamin D levels generated via sun exposure are not changed.

Helps the Immune System

GeorgetownUniversityMedicalCenter researchers found out that sunlight plays an important role in the human immune system. In a paper entitled “Intrinsic Photosensitivity Enhances Motility of T Lymphocytes” and published in a 2016 issue of the journal Scientific Reports, it is demonstrated that sunlight invigorates T cells to fight numerous infections. Sun rays contain low levels of high-frequency blue light, which can penetrate deep into the dermis, the skin’s second layer. This then energizes and speeds up the movement of the body’s T cells, thereby directly impacting how fast the body responds to the intrusion of pathogens and other infectious elements. This is probably why many people become more susceptible to common illnesses like the common colds during inclement weather.

Boosts Mood

People, who have to endure long winters in northern climates, can lift their mood with daily intake of synthetic vitamin D, according to researchers in the Loyola University Chicago Marcella Niehoff School of Nursing. Meanwhile, bright-light therapy in the morning remains the treatment of choice for sufferers of seasonal depression (SAD). Some bipolar depression patients even benefit from bright-light therapy to ease their symptoms, according to researchers from the University of Pittsburgh School of Medicine’s Western Psychiatric Institute and Clinic.

So, next time you need a fast daytime pick-me-up or stave off a looming panic attack, just walk around the block, where you can breathe in fresh air and savor the energizing sunlight. Just keep in mind that excessive exposure to sunlight is never the ultimate goal because doing so may lead to skin cancer for some susceptible individuals.

The Dos and Don’ts of Tanning!

The summer days are thriving and you should be soaking up every bit, literally. We’re not talking about running through the sprinklers at your local park or divingMan Sun Tanning into a welcoming pool in the sweltering heat. We’re talking about tanning! You should be soaking up some sun and getting the best of it before the winter comes to terrorize you with dry skin. Tanning is a welcomed practice, however, we at Rao Dermatology believe everything should be done in a safe and moderate way. The sun, as lovely as it is, is packed with UV Rays that can cause skin cancer and other skin diseases. These tips below will help you practice safe tanning so you can feel comfortable and look radiant while you enjoy your summer.

Always wear Sunscreen

Whether you’re a naturalist or you subscribe to using pre-packaged store-bought brands, using sunscreen is a must. Protection from UVA and UVB radiation is imperative due to the stammering and grave harm, primarily skin cancer, which can result from exposure. Use sunscreen that is combative and states explicitly that it contains UVA/UVB protection, and most importantly, ensure it contains other health benefits such as replenishing and nourishing your skin.

Use other skin products with UVA/UVB protection

It’s easy to think that you have the ultimate protection once you have drowned your body in sunscreen. However, other parts of your body also need adequate coverage. If you are wearing make-up, it should be able to defend you from the sun. Skinceuticals has a highly effective line of sunscreen-based lip and eye protection to give you maximum coverage for your tanning excursions.

Limit your “Face time”

Your face is much more sensitive than the rest of your body. At no point should they both be exposed to the sun for equal amounts of time.  Dermatologists recommend a maximum of 10 minutes face-tanning time. Anything longer than the allotted time can result in premature aging, dark spots, wrinkles, and discolouration. Also aim to exfoliate prior to sun tanning; it will kill dead cells and cleanse your pores.

 Don’t Bake Your Skin

First –time tanners can tan for about 20 minutes and increase each time by five to ten minutes. However, monitor your skin. Do not stay in the sun for more than 1.5 – 2 hours.
