Yesterday I advised somebody that physical activity is highly beneficial for mental health and can help more than medications would alone. The community did not like that. I am here again to remind you that physical activity is Paramount to mental well-being. Go out and garden. Take a walk in the park. Go for a jog, whatever it may be that gets you out of your current location and allows you to reflect and think.
Is it raining? Go reenact a famous old movie.
Is it snowing? Find someone to throw snowballs with/at.
Is it sunny? Go take a nap in a hammock or find an ice cream bar.
By experience, I totally agree, doing outdoors activities is great for the mind. Also, the same as darker seasons make people depressive, I’d imagine spending all of one’s free time in a dark room has a similar effect. Furthermore, there may even be cases the source of the person’s mental issues is within the walls of his/her home aside from the darkness, so taking strolls, doing activities, etc. may serve as a moment to take the mind out of such issues.
