Nature can play a significant role in reducing symptoms of depression through various mechanisms. Spending time in nature has been shown to lower levels of cortisol (the stress hormone), improve mood, increase feelings of relaxation, and provide a sense of tranquility and peace. Nature also offers opportunities for physical activity, which can help release endorphins and improve overall well-being. Additionally, exposure to natural light can regulate sleep patterns and boost vitamin D levels, which can have a positive impact on mood. Engaging with nature can also promote mindfulness and a sense of connectedness, which are important for mental health.
