When we spend more time outdoors, we use less energy for lighting, watching television or operating appliances. Daylight in buildings is composed of a mix – direct sunlight, diffuse skylight and light reflected from the ground and surrounding elements. Light from the sun is intense and directional. Light from the sky is soft and diffuse.
Researchers found that those with higher sunlight exposure during the day had significantly higher levels of macular pigment, which prevents age-related vision loss. Summer is a sight for sore eyes in more ways than one. The best-known benefit of sunlight is its ability to boost the body's vitamin D supply; most cases of vitamin D deficiency are due to lack of outdoor sun exposure.
