 Yes. Works every time. I’d add that it has to be done outside, in fresh air. 
 Outside in fresh air is best 
 I was a long distance runner for years, could never run on a treadmill. I would run outside through entire Boston  winters regardless of temps except when impossible after major snowstorms. On Sundays I'd do 10 or 12 or 14 miles, loved it. Outside is awesome but not in the hot sticky summer so I would just not run at all for three months cos I just can't stand those treadmills!
