Does Timing Matter?
Yes. While red light is not stimulating like blue light, timing still affects outcomes.
Recommended use:
-
Late afternoon or evening
-
At least 30–60 minutes before bedtime
Avoid overly intense sessions immediately before sleeping.
Session Length and Intensity
Effective sessions usually last:
-
10–20 minutes for targeted areas
-
15–30 minutes for full-body exposure
Professional devices like Merican red light therapy systems are designed to deliver safe, controlled intensity.
