Movement and exercise are really effective ways to maintain good physical and mental health. Simply getting up and moving your body can help fight depression, relieve stress, provide a sense of well being and add years to your life. Evidence suggests that focusing on your body as you exercise can help your nervous system to reset and move past stress responses related to trauma and PTSD. Outdoor activities in particular have been shown to reduce anxiety and symptoms of PTSD.You don’t have to get fit enough to run a marathon if that isn’t your goal, just finding 15 minutes a day to stretch your muscles when you don’t have much energy is enough. Exercise increases your energy rather than drains it, so a little sweat will give you a boost even when you are wiped. Go at a gentle pace, respect your physical limits, and build stamina over time.
