Sleep is the most effective stress reliever we have. Lack of sleep is a key cause of stress. Try to get your 8 hours every night.
Exercise is a great way to relieve stress. Now, this does not mean go run a marathon or lift heavy weights. But a stretch break or a short walk can improve your mood and increase endorphins thus relieving your stress. My personal favorite form of movement is yoga. Especially Yoga with Adriene!
It has been scientifically proven that meditation can decrease stress and improve your mental well-being. Meditation can also offer you techniques to prevent stress before it starts.
Music affects both our emotions and our body. Slow music can quiet your mind and relax the muscles in your body. While upbeat music can increase your happiness.
Talk it Out
Calling up a trusted friend and talk about your problems. Your friend can be a voice of reassurance to help put things in perspective and get you back on the right track.
