Sunlight can improve your sleep: Research indicates that an hour of natural light in the morning will help you sleep better. Sunshine regulates your circadian rhythm by telling your body when to increase and decrease your melatonin levels.
Reduces stress: Melatonin also lowers stress reactivity and being outside will help your body naturally regulate melatonin, which can help reduce your stress level.
Maintains strong bones: One of the best (and easiest) ways to get vitamin D is by being outside. Vitamin D helps your body maintain calcium and prevents brittle, thin, or misshapen bones
Strengthens your immune system: Vitamin D is also critical for your immune system, and with consistent exposure to sunlight, you can help strengthen it.
Helps mental health: Sunshine boosts your body’s level of serotonin, which is a chemical that improves your mood and helps you stay calm and focused.
