1. Get more sleep
Are you getting at least 6-8 hours of sleep at night? Sleep is restorative, a time for your brain to rest and make sense of what happened the day before. If you are able to easily doze off during a movie or immediately fall asleep on a plane in middle of the day you are not getting enough sleep.
2. Get physical
Get your heart pumping. Exercise, formal or informal such as long walks, yoga, and dancing help you get into your body and out of your head. Exercise allows for release of endorphins, the feel good hormones!
3. Help out someone else
When you help others, e.g. mentoring an at-risk kid, paying for coffee for a stranger, or volunteering at a hospital, you get to connect with others. The unpleasant feelings we get from depression and anxiety, or the isolation we feel from chronic pain can disconnect us from people around us.
