Light: The drug we should be taking

Have you ever considered light as a therapy? Classically referred to as Phototherapy or Heliotherapy, this form of treatment consists of exposure to daylight or specific wavelengths of light.

Studies1 have shown that the use of ambient interventions (light, music, sound, color, visuals, etc.) may act as a complementary treatment leading to improved health outcomes with few or no side-effects. It can also help improve the patient’s overall perspective of the healthcare delivery. This approach is a wining combination for the health industry because patients’ receptivity is increased and it facilitates workers’ interventions for treatment and diagnosis.

Implementation of ambient therapy is already helping some maternity wings to ease the birthing process, while some psychiatric wards benefit from the outcomes of lower levels of anxiety and stress. Ambient therapy can also help improve or treat conditions like Post Traumatic Stress Disorders (PTSDs), depression, cognitive and memory impairment, sleep disorders and can raise motivation levels in rehabilitation environments.

The reason is somewhat simple: Levels such as Vitamin D, Melatonin and Serotonin from light, influence the chemical reactions that are responsible for regulating humans’ circadian system, and pain thresholds among other things. So, essentially, Light is like a superfood to our body!

Next time you are at a doctor’s appointment or dentist office, you might notice a few therapeutic light sources. And now, you will know the reason behind them!
