    Light exposure increases androsterone by 200% in males

    This is one of these good, old studies from the 30ies. They applied light to different body parts of depressed individuals and measured androsterone output afterwards. The light contained UV- and infrared light, similarly to sunlight: "...the spectrum of this lamp consists of 52% infrared...

    People who sunbathe often have much higher exposure to environmental toxins -> skin cancer

    Our species evolved for hundreds of thousands of years in Africa, spending most of our lives under direct sunlight. At times, there was much more UV radiation reaching Earth than today (magnetic field fluctuations, changes in solar activity...) Nowadays, air is full of garbage ranging from...

    PUFA/Statins Promote UV Damage & Skin Cancer (melanoma), Cholesterol Is Protective

    Several people asked Peat over email about the dangers of sun exposure. He responded by saying that the main danger is the lipid (PUFA) perodixation caused by the UV lights and that taking some aspirin, vitamin E, or niacinamide greatly reduces the damage. The study below confirms that PUFA may...

    Sunlight And Aspirin Can Treat Multiple Sclerosis (MS)

    The link between sunlight exposure and incidence of MS is well-known and strongly pointed to a metabolic origin of the disease as early as the 1960s. It led to a few underpowered trials with low dose vitamin D, which did not find much benefit. However, a recent trial with a higher dose (10,000...

    Ketotifen Prevents Skin Aging/wrinkles Due To UV Light

    Meet your new beauty ingredient - ketotifen. UV light exposure is one of the main triggers of visible signs of skin aging and contributes to lipofuscin formation as well. It looks like ketotifen may be able to prevent that damage and given its leukotriene and histamine antagonism it may be a...

    Sun Exposure At The "Safe Hours" Is Worse

    This is just what I believe. Authorities advice to get sun exposure after 4 p.m. If you sunbathe after 4 p.m., I believe you're more likely to get skin damage. What happens is that the damage from UVA rays is less noticeable. UVA tans you, but it doesn't produce sunburn. So you don't notice all...
