text: Spend time in nature. Mother Nature can have a powerful influence on depression. Research suggests people who spend time in nature have improved mental health. Exposure to sunlight may offer some of the same benefits. It can increase your serotonin levels, which can provide a temporary mood boost. Consider taking a walk at lunch among the trees or spending some time in your local park. Or plan a weekend hike. These activities can help you reconnect with nature and soak in some rays at the same time.
