So let’s say you have noticed you are in a depressed mood and asked yourself what can I do, here’s some suggestions to get you started:
Check your posture. Chances are your shoulders are rolled forward and your head stooped down. Break this pattern. Raise your head, roll your shoulders back, open your chest and take a deep breath.
Check your surroundings. Are you in a dark stuffy room by yourself? If any of that is true, change it. Turn the lights up and open a door or window to air it out. Consider finding someone else to spend some time with.
Check your motion. Have you been lying or sitting still for an extended period of time? Get up and do something physical. Even just going for a twenty minute walk will make a world of difference.
