Reading outside may be challenging at times. Here are some benefits why you should include a good book with your next relaxing day outdoors. 1. Vitamin D A daily dose of natural vitamin D from the sun will support the health of the immune system, brain, and nervous system. 2. Earthing with Nature “Earthing” with nature has been shown to stimulate greater activity in areas of the brain that are responsible for immune system health, love, and clear decision-making. Just being outside under a rustling tree or on the grass can help you relax. 3. Decreased Stress By taking an activity you would usually do indoors outside (such as reading a book), you expand your world and begin to mentally imprint the presence of nature into more aspects of your life, which can decrease stress and anxiety. 4. Natural Light The more natural light, the better. Compact fluorescent light bulbs as your main light source all day may increase your risk for migraines and eye strain. 5. Improved Sleep Sunshine regulates your internal clock so you can enjoy improved sleep when you get home. The more sleep you get, the more energized you'll feel.
