There's a lot of websites on internet that claim a number of games, exercises and diets to be actually helpful in this regard but they do not provide any authentic citation. Some of them are complementary while few are contradictory.
I'm confused and really don't understand which tips are most thoroughly updated according to research.
UPDATE 1
I recently read articles.mercola.com. It appeared pretty authentic because the author is an active researcher.
UPDATE 2
By natural I mean non-medicinal means like Exercises, diets and games. I'm looking for them because I'm already under medication and wish to try something non-medicinal for recovery.
P.S. I'm new so guide me to improve this question.
