Sunshine Is for Health
51; The old wisdom: stay out of the sun. The new wisdom: your life could depend on getting sunshine: about 10-15 minutes of exposure three times a week.
Science Daily reported that Vitamin D, produced in the skin by exposure to sunlight, provides more health to the body than previously thought. Health professionals have known for a long time that Vitamin D is necessary to prevent rickets and bone disorders. Now, evidence is growing that Vitamin D also fights cancer, cardiovascular disease, and autoimmune diseases.
No one is suggesting overexposure. Clearly, too much sunlight raises risks of skin cancer and ages the skin. Still, many people are probably getting too little sunshine in their life. Those at northern latitudes, and those with dark skin, may need to take more steps to get their arms and legs and faces out in the noontime sunshine. The elderly and office workers may also be vulnerable to Vitamin D deficiency.

One thing not stated in the article is the remarkable correlation between the energy of sunlight reaching the earth and the chemistry of proteins and enzymes that are activated with this energy. The lower energy of light from red dwarf stars might not be sufficient for biological reactions, while the light from hot blue stars would produce too much ionizing radiation.
This is one of many “Goldilocks” parameters of physics and astronomy that is just right for our health. The correspondence of astronomy with biology, that permits sentient beings to make scientific discoveries, is silent witness of intelligent design. Expose yourself to that light.
