21. Light Therapy
Lack of sunlight is well known for causing depression. Natural sunlight is best. It promotes vitamin D synthesis as well as Nitrous Oxide which is a vasodilator. This lowers blood pressure and has other health benefits. Sunlight also helps regulate melatonin levels needed for healthy sleep.
Walking outdoors in the light is one of the best ways to help depression. In the winter, some people use light boxes to boost exposure.
Many people will find that supplementing D-3 in the months they cannot get outdoors to be helpful. Dosages range from 2,000 IU to 10,000 IU daily. Consult your nutritionist.
