Prescription: A walk in the park to improve your health (ParkRX)

[Now Doctors Are Prescribing Walks In The Park To Get Us Off Our Butts](http://www.fastcoexist.com/3030756/now-doctors-are-prescribing-walks-in-the-park-to-get-us-off-our-butts?partner=rss) Fast Company

Follow-up interviews show an average increase of 22 minutes of activity per week

Unfortunately, 22 minutes of noon-sunshine only works out to about 500 IU when walking like a golfer (short sleeves) and no sunscreen

Even optomistically assuming that half of the walking were in bright sun, ParkRX would result in only

35 IU/day

However, getting out and moving in the fresh air is great!
