Keep Stress Away
Easier said than done, but you should try to keep stress levels, as low as possible throughout the day. When you are stressed, your heartbeat is far from normal and increases rapidly, as it stimulates the sympathetic nervous system in your body. This is not at all a good sign and you could face serious health issues. Try doing yoga, practicing meditation, relaxing by lying down and doing nothing for a while, listening to music, doing something you enjoy and laughing, among other things.
