🔼: # Sunlight and Light Exposure --- Morning light exposure aids [[⭐️ Sleep]] and reduces [[💡 Depression]]. [[🔑 Everything is connected to everything else]]. Our bodies use the sun to set our sleep schedule. When we look toward the sun shortly after waking, ideally for 10-30 minutes, it helps us wake up and it gives us a mood-bump. The sun also tells our body to start a timer to release [[💡 Melatonin]] in the evening. Ideally we get this from sunlight, but a [[🛠 Light Therapy Lamp]] / SAD lamp will also work. Try to get a wide look at the horizon, take it all in. We could go for a morning walk every day, or out to a coffee shop or breakfast with a friend a couple times a week. During the day, use overhead / ceiling lights. If we wait too long to get this light exposure, especially if we wait until evening, we increase our risk of [[💡 Depression]] because we're getting the wake-up when we should be going to bed and because light inhibits melatonin. The cells in our body which react to light are surprisingly difficult to stimulate in the day, and annoyingly easy to stimulate at night. After about 4pm, turn off overhead lights and use desk or floor lamps, similar to how the sun sets as the day goes on.
