Everything about sun protection.

Since most of us don’t work outside these days, it actually takes effort to get daily sun, rather than to avoid it.

To protect yourself from the sun, which gives you vitamin D, in order to fill yourself with vitamin D in pills. To protect yourself from the sun, which may cause a skin cancer, in order to be deficient in vitamin D, which helps to protect against many types of cancer. At the same time using creams that interfere with hormones and contain toxins, upsetting the balance again. And so on.

Every time I’m told that something is vital to me, I involuntarily wary. I’m also not a fan of the idea that one size fits all. If you need to protect yourself from the sun, take a sunscreen and apply it, isn’t that it? No, not so simple. So shall we apply that cream or not?

Introduction to ultraviolet light

Ultraviolet types:

Ultraviolet radiation is classified into three types, depending on the wavelength: UVA, UVB, UVC. The shorter the wave, the more harmful it is and at the same time penetrates the skin less. The atmosphere completely protects us from the most harmful UVC.

The atmosphere also filters most UVB, but some part is still able to penetrate the upper layers of the skin, and this is a much larger part than the nature intended, due to chemical damage of the ozone layer by humans. UVB is responsible for long-term tanning and exactly burning, promotes skin aging and skin cancer. And provides us with the so-called vitamin D.

The longest wave, UVA, is about 95% of all ultraviolet light that reaches the earth’s surface. It can penetrate into the deeper layers of the skin and are responsible for the immediate tanning effect, promote skin aging and wrinkles. It can also penetrate the glass. Recent studies have found that UVA can contribute to the development of skin cancer as well.

What affects the radiation power:


The more sunburns we get in a lifetime, the higher the risk of skin cancer. Children’s skin is especially sensitive, and sunburn should be avoided completely. How many burns an individual can safely survive is very individual: it depends on genetics (family history of the disease and skin color), time spent in the sun, the level of each skin burn, and so on. The easier your skin burns, the higher the risk.

Introduction to suncreen


The first thing we pay attention to when looking at a sunscreen bottle is the abbreviation SPF (sun protection factor), which indicates the level of protection of the skin from burning, more precisely from UVB rays, but doesn’t measure the level of protection from no less dangerous UVA rays. Therefore, dermatologists also recommend looking for the words “broad spectrum”, which denote protection from both types of rays. It is recommended to choose a product with at least SPF 30. If you are dealing with water and sweat, you should also choose a waterproof product that should protect for about 40 minutes in water or a very waterproof – 80 minutes.

In order for a sunscreen to be really effective, it’s necessary to use a proportion of 2 mg per 2 cm2 of the body and apply it every 2 hours. Most people use a quarter to a half of the required amount and do not renew protection in time, if they do that at all.

The SPF scale is not linear:

Sunscreen vs sunblock

Some products protect the skin through chemical processes, and some block or reflect the sun, creating a physical barrier. The second type usually contains particles of titanium and/or zinc.

Sunscreens contain elements that require proof of safety. The long-term effect of the use of sunscreen is unknown to science.


Skin cancer

There are three main types of skin cancer: 2 types of carcinoma and melanoma. If detected in time, each of them is treated, and control of sunlight can reduce the risk of cancer. This includes the fact that a healthy amount of sunlight promotes good health and, in fact, reduces the risk of melanoma.

When you spend much of your day treating patients with terrible melanomas, it’s natural to focus on preventing them, but you need to keep the big picture in mind. Orthopedic surgeons, after all, don’t advise their patients to avoid exercise in order to reduce the risk of knee injuries.

In the course of evolution, humans have learned to naturally protect themselves from solar radiation by producing melanin. While migrating further away from the tropics and resting from the sun in winter, organisms learned to produce less melanin to get what they needed from the sun, and began to produce much more protein, which retains vitamin D for later use. In the spring, as the sun grew stronger, they gradually accumulated sunlight. Sunburn was probably a rarity until modern times, when we closed our offices and began to burn ourselves on the beaches once a year. Such a sharp drop really sounds dangerous.

The best long-term research available shows that sunscreens have very little effect on melanoma, the most dangerous of skin cancers, and some components of sunscreen can even cause other forms of cancer.

Dangers and potential dangers

Vitamin D

Most likely, sunscreens also do not block vitamin D, because people mostly do not use them properly (often enough and in sufficient quantities), and therefore, hurray, they still get their vitamin D… and do not receive protection from ultraviolet light, and studies claim that the higher the SPF in the sunscreen, the more one tends to relax and ignore the rules of application.

However, what we are advised is the constant use of sunscreen, regardless of a place of the residence and a season (and people protect themselves, from head to toe, some even at home, including “protection” from the ‘blue light’, i mean with sunscreen; where did you take all thatvmoney from? ?) and supplementation with artificial vitamin D, which, however, shows a minimum to zero result. As I btw suspected.

The Australians realized that something was wrong already in 2005, their dermatologists officially stated that ultraviolet light has both beneficial and harmful effects on health, and you need to keep a balance so that the beneficial doesn’t turn into harmful. And the benefit is not only in obtaining vitamin D.

And that’s how, having common sense, we approach the question number 1.

How to protect yourself from the sun?

Sunlight triggers the release of a number of other important compounds in the body, not only nitric oxide but also serotonin and endorphins. It reduces the risk of prostate, breast, colorectal, and pancreatic cancers. It improves circadian rhythms. It reduces inflammation and dampens autoimmune responses. It improves virtually every mental condition you can think of. And it’s free.
