Try a yoga sequence
Practicing yoga regulates stress response systems, which decreases physiological arousal -- making you a little less crazy. The combination of exercise and relaxation improves mood, boosts energy, and reduces stress.
Luckily, you can practice yoga in the comfort of your home in less than 30 minutes, thanks to some free instructional YouTube videos. Being able to control your breathing and being in the moment is part of what makes yoga so beneficial to your health. It's also a bomb-ass skill. And if you think yoga is boring, then you obviously haven't tried beer yoga.
Organize your mind with a list-making exercise
You might have a long to-do list that includes picking up your laundry, walking the dog, calling your mom, or meeting your friends for happy hour (which takes priority). All of that multitasking, on top of getting distracted by cute cats on the internet, can make you go crazy.
