I know you already sense this to be true, but playing outside does a mind (and body) good, more than indoor exercise, so says science. Again, science confirms and affirms our intuition. I love it when that happens! The sun is shining today and spring is around the corner, so Go Play Outside!!
"...exercising in natural environments was associated with greater feelings of revitalisation, increased energy and positive engagement, together with decreases in tension, confusion, anger and depression. Participants also reported greater enjoyment and satisfaction with outdoor activity and stated that they were more likely to repeat the activity at a later date.
Our research, which brings together data from a wide variety of sources, adds significant weight to the case for spending more time in the natural environment as members of the public and their clinicians fight to counteract the negative outcomes of modern living, such as obesity and depression."
