The Benefits of Red Light Therapy for Mental Health

In the past decade, red light therapy (RLT) has been widely considered as an alternative therapeutic approach for certain health conditions. While its positive impact on areas like skin care, pain management, and muscle recovery has been established, another crucial area where RLT is shown to be effective is mental health and its related conditions like stress, depression, and anxiety.

What is Red Light Therapy?

For those not yet acquainted with the concept of RLT and red light therapy lights, it is basically low-level laser therapy or photobiomodulation (PBM). In this process, low-wavelength red light penetrates the skin and reaches the deeper tissues to stimulate the cellular processes. This promotes healing, reduces inflammation, and improves blood circulation. The wavelength is of the optimal range for tissue absorption, which is between 600 to 650 nanometers.

How Red Light Therapy Can Help Reduce Stress and Anxiety?

While you understand that the red lights penetrate the skin and, hence, might be beneficial for your skin and muscles, you might wonder how it is applicable to mental health and wellness. Well, the RLT lights influence your body’s natural biological systems. Stress and anxiety are usually connected with overactive sympathetic nervous activity. This is commonly referred to as the “fight or flight” response, and it triggers symptoms such as rapid heart rate, erratic breathing, and muscle tension.

Red light therapy promotes a calming effect on your nervous system. It stimulates the mitochondria and boosts the production of adenosine triphosphate (ATP). Now, this ATP is crucial for cellular energy and function, and when produced in large quantities, can balance the autonomic nervous system. The results are reduced overall inflammation and a state of relaxation. 

Another way that red light therapy affects your mental state is by regulating cortisol, the so-called stress hormone. Reducing cortisol through red light therapy results in a noticeable decrease in stress and anxiety levels.

Can Red Light Therapy be Used for Treating Depression?

Depression is a complex mental health condition caused by subsequent disruptions in brain functions. Red light therapy has a significantly positive influence on the brain’s structure as well as its neurochemical environment.

Studies in the field point out that the red therapy lights can stimulate the release of serotonin, a neurotransmitter responsible for mood regulation. Depression indicates low serotonin levels, while higher levels of serotonin can boost overall mood and well-being. This comes along with the fact that RLT supports the growth, maintenance, and survival of neurons or what is more specifically, the neurotrophic factor (BDNF). Lower BDNF results in conditions like depression, so an increase in its production improves both cognitive function and emotional regulation.

How to Use RLT for Mental Health?

For anyone considering red light therapy to boost mental health, consistency is key. Using the therapy regularly is the way to feel its effects. Some might start feeling the effects following a few sessions, while others might need up to a week to notice significant changes. Ideally, the red light therapy sessions should last somewhere between 10 to 20 minutes and two to three times each week for the best results. The good thing about red light therapy is that it is non-invasive and with zero to minimum side effects. Hence, it can very well be integrated into your self-care routine. 

The Ongoing Research in the Field

Research about red light therapy and its effect on mental health is ongoing and mostly in the early stages. That being said, several studies have already confirmed its impact on boosting the mood and reducing the symptoms of anxiety and depression. More large-scale clinical trials are yet to be conducted to understand the full therapeutic benefits of red light therapy. For now, it is best used as an alternative approach toward overall well-being with heightened effects on some areas of your physical and mental health.

Final Thoughts

Red light therapy is revolutionizing the alternative healthcare sector with its multiple benefits. RLT works well in restoring the equilibrium of your body and mind, relieving you from physical and mental stress. It is always advisable to consult a medical practitioner before going for such therapies, especially for people suffering from specific health conditions.
