How long and how often should I use red light therapy?Updated 15 days ago

There's no one-size-fits-all dose. Someone who's often outdoors and in good health may need less than someone who rarely sees the sun. Find your own sweet spot by making small changes, because using too much can cancel out good results just as using too little can.

• Upper limit: no more than 20 minutes in total in any 6-hour period. More is not expected to work better.
• How often: 3 to 6 times a week, with one day off a week generally advisable.
