Medical Video: What Exactly Does The Sun Do To Your Skin?
Behind the myriad of benefits of sunlight for health, it turns out that this blinding glow of the eyes can also have an adverse effect on your body. Eits, but not just cause sunburned skin (sunburn) Just like that! There are still various other sun hazards that you should know. Anything, huh?
Various sun rays for the health of the body
Who, who doesn't like to travel or vacation when the sun is bright? But you should still limit exposure to excessive sunlight, especially if it is not accompanied by a protector, which can lurk your health.
1. Reddened skin
Jason Reichenberg, MD, as a lecturer at the University of Texas-Austin's Dell Medical School, explained that spending too much time in the sun without protective clothing or sunscreen can cause redness in some areas of the skin, maybe even permanently or difficult to cure.
Because, as you get older, the sun's rays can subconsciously thin the skin while relaxing the skin structure around your blood vessels. Gradually, the blood vessels will widen to give rise to a reddish brown area in several parts of the body.
This process can also cause collagen in the skin to spread which makes blood vessels appear visible on the surface of the skin.
2. Vision deteriorates
Visual impairment has become a consequence that must be faced by everyone as we get older. But in addition to age, a study found that exposure to sunlight for a long time turned out to aggravate this condition - especially for men and women over 40 years old.
According to a study from Fordham University in 2011, ultraviolet (UV) light has a bad effect on the eyes because it increases the chance of developing cataracts which can lead to blindness.
Not only that, the danger of direct sunlight can also interfere with the function of the retina which will reduce vision for a long time. Impaired retinal function is triggered by glaucoma and macular degeneration, reported by Health.
3. Skin aging
It is undeniable that UV rays can cause the skin to age faster. This is because sunlight can penetrate directly into the middle layer of the skin (dermis) which causes elastin cells in the skin to accumulate abnormally.
When the number of elastin cells is sufficient, a type of enzyme will break down collagen and elastin, which then changes in the structure of the skin. Exposed to sunlight will then accelerate the aging process which leads to wrinkles, spots, and other skin damage.
4. A severe rash arises
There are several medical conditions that easily cause a rash on the skin. For example for people who have a sun allergy, it is very easy for him to experience reddish skin even though only a few minutes under the sun.
More severe allergic reactions can even cause porphyria disease, a condition that makes a person afraid of excessive sunlight. The danger of sunlight caused will make the skin instantly flushed until it blisters when exposed to sunlight.
5. Lower the immune system
The body is equipped with an immune system that is tasked with fighting the arrival of various infections and abnormal cell growth. This immune system defense involves the work of white blood cells or lymphocytes (T cells) and langerhans cells.
Well, skin exposed to sunlight too often will trigger the release of active chemicals that will disrupt the body's immune system. As a result, the ability of the immune system to block the entry of the infection weakens.
