Sunlight Benefits For Health

Sunlight Benefits For Health

Dr. Robert S. Stern, chair of the Department of Dermatology at Harvard-affiliated Beth Israel 

Deaconess Medical Center, calls them "Solar-phobes" people so concerned about getting skin 

cancer that they stay inside or cover bit of skin. "They cover up like they were going out into the

Arabian Desert" he says. The marketing  of ultrablocking sunscreens and special sun-protective 

clothing plays into these fears.

There's no getting around the fact that sunlight is hard on your skin. Age gets blamed for 

wrinkles and rough, dry skin. But the real culprit is a combination of age and sun that dermatologists 

call photoaging. The short UVB wavelengths that cause sunburn can also damage DNA and 

suppress the skin's immune system. The longer, more penetrating UVA wavelengths may create

highly reactive oxygen molecules capable of damaging skin cell membranes and DNA inside.

Here we listed the benefits of the Sunlight for the health.

(1)   Start with the obvious.Sunlight is the initiator of Vitamin D3 creation in our bodies. 

Sunshine's UVB rays interact with the cholesterol in our skin that ignites a process to create Vitamin D

from our kidneys and liver. This doesn't happen without sunlight.

Exposing more bare skin to sunlight is necessary for 20 to 30 minutes at least three or four times weekly.

Glass windows and windshields block UVB rays while letting in UVA rays, which can be harmful.

One irony is that most sunscreens block only UVB rays, thus inhibiting vitamin D3 production. As a

pre-hormone, Vitamin D3 has many internal health function.

 Vitamin D3 production from sunlight has  its own shut-down mechanism, safeguarding you from

overdosing  Vitamin D. But if you wash exposed skin with soap too soon, you wash away

the skin's oils that have just begun the Vitamin D process.

(2). Dr .Johanna Budwig promoted daily sunlight exposure in conjunction with her famous Budwig diet

for curing cancer. She had become aware of sunlight's electromagnetic contribution to the dietary 

elements of her successful cancer cures.

(3). During long period without sunshine, many get depressed. It called seasonal affective disorder

(SAD). Besides feeling gloomy, people experiences low energy.

(4). A substance in our bodies called melatin may be able to convert sunlight into metabolic energy.

There are studies looking into this.

(5). Sunlight exposure was discovered to reduce the need for pain medication, stress, and anxiety 

among post operative patients in one hospital that conducted a study in 2005.

(6). A 2012 neuroscience study determined that those who had six hours of sunlight exposure

during the day were more alert in the evening.

(7). A 2011 dermatological study observed the sunlight exposure helps burn subcutaneous fat,

which is unattractive but doesn't necessarily affect cardiovascular health adversely.
