Exercise affects how we feel
Exercise has effects on certain chemicals in the brain, like dopamine and serotonin. Brain cells then use these chemicals to communicate with each other. This means exercise can improve our concentration and focus. It can also stimulate the release of endorphins and epinephrine, which can improve mood.
Exercise reduces muscle tension and general stress. It leaves you feeling relaxed both physically and mentally.
Exercise can give you a sense of control over your life. You feel that you have choices and that you are looking after yourself.
Finally, exercise improves sleep because it acts as a physical stressor to the body. The brain compensates for this stress by increasing deep sleep. This is why people tend to sleep soundly after a healthy workout.
What you can do
Find an activity that is enjoyable
If you think you hate sport, try to find a form of exercise that doesn't feel like exercise - dancing, dog walking, ultimate frisbee?
Build more physical activity into your life
Add more exercise into your daily commute by walking a few train stations or by skipping the tram completely.
It’s best to do about 30 minutes of moderate physical exercise around five days a week. Moderate exercise means you're working hard enough to raise your heart rate and break a sweat, but you can still chat.
Exercise with a friend
A friend can help you stay motivated so try to arrange a friend to be your regular gym or dance buddy.
