It is well known that ambient light can influence aspects of human physiology including brain function, circadian rhythm, heart rate, and hormone release. But most studies of this have focused on the effects of light during the night; few have examined the body's response to light during the day.
New studies exposed participants to 21 minutes of bright white light in the morning. They became more alert, and brain images showed that regions of the brain involved with alertness and some cognitive processes became more active.
Those brain regions are also involved with attention and arousal regulation. This means that light exposure DOES affect performance and alertness at work.
Sitting inside a poorly lit office surrounded by incandescent or fluorescent lighting day and night starve your body of the unfiltered ultraviolet light that helps your body produce vitamin D. Full-spectrum light improves our health. More lumens the better!
The human race evolved under the sun, and for thousands of years lived in close harmony with its heat and light. Sunlight not only increases your energy and general well being, but it also helps:
- Lowers your cholesterol
- Teats multiple sclerosis and osteoporosis
- Prevent and treats cancer
- Lowers your blood pressure
- Increases the value of exercise
- Improves your body's ability to detoxify
See the light ... the bright natural light.
