when i am really stressed, i go for a brisk walk. Sounds too simple but it works for me. energy that has no place to go, now has a place to be released. i am able to rid myself of whatever worrisome thoughts are troubling me.
Now if you are in a very cold climate, maybe you can do some other kind of exercise, jumping jacks, sit ups, climb stairs...or,
go to your happy place.
i have a mental happy place but i also have created a 'happy place' in my own little corner of the world.
i found a puzzle that is my concept of relaxation..it is a beautiful field filled with flowers and tall grasses with rich greens and vibrant colors in the flowers..There is a bubbling brook that passes through it.
i escape into that place if i am terribly stressed and cannot go for a walk.
