Spending time in nature is now linked to more than 100 studies showing the positive impacts on mental health.

A new discipline has emerged, called ecopsychology, shedding light on the benefits. Being out in nature helps reduce stress, anxiety and depression, decreases anger, boosts positive mood, and more based on researchers findings.

So how much time should you be spending in nature? A study of nearly 20,000 people, published in Scientific Reports, suggests you should spend at least two hours a week in nature to feel healthier.
