There are days I was doing absolutely nothing and I still feel like I just got chased by a tiger in my own backyard. Well, that is what anxiety or stress can do to you by signaling danger to your brain (it must be imaginary danger because I definitely never see it) and is flooding your body with adrenaline. Most of the time, we do not even realize our body just went into fight or flight mood because we are late for a class or meeting until we feel the bodily symptoms, such as sweating, increased pulse, and it seems something is going on in our belly. Although, this adrenaline rush aka fight or flight syndrome used to be very helpful in the Stone Age when various animals thought humans would make great lunch, nowadays, it seems less useful since looking like I just ran a marathon will not help me during my exam. If you want to find out more about this topic and how humans developed but the fight and flight syndrome was not notified, I can recommend "Why Zebras Don't Get Ulcers" by Robert Sapolsky.
As long as you do something to burn the excess adrenaline, you should feel better and more relaxed afterwards. Best case scenerio would be to do something for about 30-60 minutes everyday, such as chasing your dog, a walk around the neighborhood, aerobic classes, or any other kind of sport. Surely, exercising will not magically completely dissolve anxiety or stress in our lives, but it will at least decrease it to some degree.
