Sunlight exposure

A balanced amount of sun exposure is seen as important to general health[6][7]. A lack of vitamin D, which is typical for lack of sun exposure, is linked to rickets[11], osteomalacia[12], thyroid issues[13], depression[14], seasonal affective disorder[3], breast and other cancers[1][2], obesity[15], Multiple sclerosis (MS)[5] and more. Too much sun exposure can lead to skin cancer[9], reduced immune system functioning[8]. High lifetime cumulative UV exposure is responsible for significant age-associated dryness, wrinkling, elastin and collagen damage, freckling, age spots and other cosmetic changes[10]. Long-term sunlight exposure is known to be associated with skin aging, immune suppression, and eye diseases such as cataracts and macular degeneration[4]. Short-term over-exposure is the cause of sunburn, snow blindness, and solar retinopathy.

I do not agree with this statement. I somewhat agree. This may sometimes be representative. I agree with this statement. It describes my situation very well.
I am familiar with UV types and what SPF levels for sunscreen to use.
Before travelling to a new sunny place I check the UV index there.
I wear proper clothing, use protective sunscreen when the sun is strong.
I get healthy doses of sun throughout the year.
I avoid sunbeds.
I go outside most days and get a little sun (or have D-vitamin supplements)
I make sure I never get sun burns.
Before going to a place with stronger sun I gradually adjust my exposure.
