Genes are a factor of how humans metabolize sunlight; as is skin type. For instance, people with pale skin that burns easily in the sun are likely to get skin cancer if exposed to too much sun. The timing and duration of exposure is also a crucial factor when it comes to how our bodies metabolize sunlight.

What is the power of the Sun?
The Power of the Sun. Vocabulary. By Kimberly Dumke. Friday, January 21, 2011. The sun is the closest star to Earth. Even at a distance of 150 million kilometers (93 million miles), its gravitational pull holds the planet in orbit. It radiate s light and heat, or solar energy, which makes it possible for life to exist on Earth.
Why is solar energy important to agriculture?
Solar energy is essential to agriculture —cultivating land, producing crops, and raising livestock. Developed about 10,000 years ago, agriculture had a key role in the rise of civilization. Solar techniques, such as crop rotation, increased harvests. Drying food using sun and wind prevented crops from spoiling.
What is solar power?
Solar power —the conversion of sunlight into electricity —is yet another application of solar technology. This can be done in a number of ways. The two most common are photovoltaic (solar cells) and concentrating solar power. Solar cells convert sunlight directly into electricity.
How does SODIS work?
Developed in the 1980s, SODIS involves filling plastic soda bottles with water then exposing them to sunlight for several hours. This process reduces the viruses, bacteria and protozoa in water. More than 2 million people in 28 developing nations use this method daily for their drinking water.
How does solar energy work?
Unlike solar cells, which use sunlight to generate electricity, concentrating solar power technology uses the sun’s heat. Lenses or mirrors focus sunlight into a small beam that can be used to operate a boiler. That produces steam to run turbine s to generate electricity.
Why did early civilizations use windows and skylights?
This surplus of food allowed for denser populations and structured societies. Early civilizations around the world positioned buildings to face south to gather heat and light.

Sunlight exposure impacts how much melatonin your brain produces, which is what tells your brain when it is time to sleep. When it gets dark, you start producing melatonin so you are ready to sleep in about two hours. With more sunlight in the summer, you are likely to feel more awake. Dr. Bligard points out that modern technology has allowed us to change our light exposure artificially with lights, TV screens and computer screens (including tablets and cell phones). Consequently, the incidence of insomnia is much higher now than it was before these devices were invented.

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 every 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.
What happens if you have a short UVB?
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 the DNA inside.

Why do we need to invest energy?
Basically, we need to invest energy to bring order from disorder. For the formation of life different substances have to come together which are of higher entropy and combine to form living DNA/RNA of lower entropy. This decrease in entropy is mandatory for life to begin and for required biological processes to happen.
