How Does Distance Affect Treatment Time?

Distance and treatment time are directly connected when using red light therapy. Together, they determine the total amount of light energy (dose) your body receives during each session.

The Relationship Between Distance and Dose

As distance increases, light intensity decreases. To compensate, users often extend session duration. This creates a trade-off:

• closer distance → higher intensity → shorter sessions
• greater distance → lower intensity → longer sessions

Can Time Fully Compensate for Distance?

While increasing session time can partially offset reduced intensity, it is not always efficient. At excessive distances, the light may become too weak to produce meaningful biological effects—even with longer exposure.

Optimal Strategy

The most effective approach is to:

• stay within recommended distance (10–30 cm)
• use moderate session durations (10–20 minutes)
• maintain consistency across sessions

Conclusion

Distance significantly affects treatment time. For best results, balance both factors rather than relying on longer sessions alone.
