Photobiomodulation (PBM) is generally considered a safe and non-invasive therapy with minimal reported side effects when used as directed.
However, side effects may occur if overstimulation happens due to excessive light exposure.
Possible Side Effects of Overstimulation
If too much light stimulation is used too quickly, some individuals may experience:
Dizziness
Headache
Fatigue
Irritability
Agitation
Nasal congestion
These effects are typically temporary and may be reduced by adjusting session duration or frequency.
How to Reduce the Risk of Side Effects
To minimize the risk of overstimulation:
Start with one pre-set protocol per day
In some cases, gradually increase to two sessions per day
Follow recommended program durations (3–10 minutes)
Avoid running multiple programs back-to-back
- Drink a glass of water to stay hydrated
Beginning gradually allows the body and nervous system to adapt to light stimulation.
Summary
Neuronic devices are generally well tolerated, but overstimulation from excessive use may cause temporary symptoms such as headache or dizziness. Starting slowly and following recommended protocols can help reduce potential side effects.
