For those who think darker skins need sunscreen as much as others to protect against the nasty UV and skin cancer, this is wrong. Darker skins shouldn't use traditional sunscreen, even less daily. Let us explain.
A growing number of experts support the positive health effects of sunlight itself, with the implication that perhaps current sun exposure guidelines may be too rigid or even harmful. When sunlight as a whole is demonized, we at Skinergies believe in photoadaptation and narrow down to incidental sun exposure, that we should worry about.
Because symptoms are similar, telling the difference between windburn and sunburn can be difficult. Skin-damaging UV rays cause sunburn, while cold and windy weather causes windburn. Sunburn poses a long-term health risk, and may even cause skin cancer. While windburn is harmless in the long-term, but still leaves your skin red and irritated after a day of hiking, skiing, or even just walking in the park.
Somewhere in the ballpark of 10 million Americans suffer from Seasonal Affective Disorder (S.A.D.), also commonly called winter blues. Those who experience S.A.D. are. . . well. . . sad. And you can paint the sadness on a spectrum — from mild malaise to severe depression. For those who live north of a virtual line going from DC to San Jose, winter blues is a real thing.
Our daily passive exposure to sunlight year-round – even on seemingly sunless and chilly days, combined with the blue light radiations coming from our electronic devices, is where most of our photoaging - the premature aging of our skin due to sunlight and UV radiation - is happening.
