Be aware of the following potential concerns:
Never replace traditional care with chromatherapy for severe insomnia.
Epileptics should avoid looking directly at any type of flashing lights.
When using colored lights, do not look directly into the light. Receive colored light therapy indirectly by looking at an object that is lit by the colored light.
If you are on prescription medication, check the label for a light sensitivity side effect. Exposure to bright light might cause a problem.
