If you're feeling more stressed than usual, there's arguably no more fitting game to play than Gris. The game deals explicitly with mental health and is one of the more gorgeous indie titles in recent memory. If you're not busy solving the game's symbolic puzzles, you're taking in its beautiful environments or watching one of the games many engrossing cut scenes. Bring your tissues though, this one tugs at the heartstrings.
Sometimes a scenic view is all it takes to help clear the mind, and throwing in some "sandboarding," multiple modes, and intuitive, easygoing gameplay doesn't hurt either. Alto's Odyssey, the sequel to Alto's Adventure, is a mobile game that's just as much about attaining high scores as it is about taking in the world around you. You and your pals glide and fly through gorgeous landscapes while you either tap your way to the top score or just sit back and enjoy the view.
