Sunlight is the only all-natural remedy for depression and can play a significant role in lowering anxiety. Without sufficient exposure to daylight, serotonin levels can drop, leading to a higher risk of seasonal depression. Better mood in spring is therefore natural and scientifically proven. Sunshine equals life. It literally does. A study of 30,000 Swedish women shows that those who spent more time exposed to sunlight lived longer than those who had less sun exposure. In tandem with melatonin, the pineal gland hormone responsible for sleep, serotonin effectively regulates the diurnal rhythm, contributing to our recovery, counteracting infections and boosting immunity. In addition, exposure to bright light reduces cortisol levels responsible for stress and weight gain.
The sun is also the best natural source of vitamin D, which is known to be very difficult to absorb from other sources. As little as five minutes of regular exposure to sunlight, especially in the morning, is enough to benefit from this essential vitamin, which reduces inflammation, effectively affects our immunity and the condition of our skin and hair. An additional benefit of adequate vitamin D levels is stronger bones and teeth. By exposing yourself to sunlight, you also increase your calcium levels!
