The Benefits of Sunlight and Being in Nature
Getting sunlight into your eyes every day increases daytime mood, focus, alertness, and improves nighttime sleep. Viewing morning sunlight positively affects metabolism. Sunlight in your eyes early in the day and in the evening is beneficial for mental health, physical health, and performance. Sunlight must be viewed directly and cannot be derived from screens or pictures. If sunlight is not accessible, using a sad lamp can provide some benefits but is not as effective. Being near bodies of water, especially moving bodies of water, has positive health benefits due to negative ionization. Technologies exist to create negative ionization indoors, but the effects are not as significant as spending time outdoors near water. Overall, there is strong evidence for the positive effects of sunlight and being in nature.
