How Does Light Therapy Work?

Comment fonctionne la luminothérapie - CoveSkin
Light therapy, also known as light therapy, is a clinically proven method for treating various medical and psychological conditions using artificial light. From seasonal depression to acne treatment and beyond, light therapy has been shown to be effective. In this article, we'll explore in detail how light therapy works, what conditions it can help treat, and how you can use it safely and effectively.

In 1993, Quantum Devices developed a light-emitting diode (LED) that was used by NASA for plant growth experiments. NASA explored the effect of red light wavelengths on plant growth and observed a significant increase in plant growth with red light.

Surprisingly and serendipitously, it was discovered that scientists regularly exposed to this intense red light experienced accelerated healing of their skin lesions. This discovery prompted NASA to further research LEDs to promote human cell metabolism and counteract loss of bone and muscle mass in astronauts. Over time, this technology began to spread among the general population.

What is Light Therapy?

Light therapy involves exposure to specific levels of artificial light under medical supervision to treat specific disorders. It is often used to combat seasonal affective disorder (SAD), certain forms of depression, sleep disorders and skin problems such as psoriasis and acne. It also helps re-energize the skin's collagen and therefore reduce the appearance of wrinkles and signs of age.

Basic Principles of Light Therapy

Red light therapy relies on exposure to specific wavelengths of light. For the treatment of SAD, for example, the light used is very close to natural sunlight. This exposure is designed to influence brain chemistry linked to mood and sleep, mimicking the beneficial effects of natural sunlight and compensating for the lack of light during the winter months.

Types of Light Therapy

Light therapy comes in several forms, each adapted to specific conditions. Here are the most common types:

Light therapy for Seasonal Affective Disorder (SAD)

This form of light therapy uses very bright light (usually around 10,000 lux) to mimic natural sunlight. Patients are generally advised to expose themselves to this light in the morning to help regulate their sleep-wake cycle.

Light Therapy for Sleep Disorders

Sleep disorders can also be treated with light therapy, which helps readjust a person's internal body clock. Light therapy can be used to advance or delay sleep cycles, depending on the specific disorder.

Light Therapy for Skin Conditions

Dermatological conditions such as psoriasis, acne and eczema may benefit from light therapy. For these treatments, specific bands of ultraviolet light are often used to reduce inflammation and the production of abnormal skin cells. Also, red light therapy helps regenerate your collagen and reduce the signs of skin aging.

Duration and Timing of the Exhibition

The time of day and the length of time you are exposed to light are key to the effectiveness of light therapy. For skin care, for example, light therapy is often most effective when performed early in the morning. Doctors generally recommend 3 to 5 minute sessions each day.

Conclusion

Light therapy is a fascinating and scientifically supported approach to treating a variety of medical and psychological conditions. Whether it's to improve your mood, regulate your sleep, or treat skin conditions, light therapy offers a drug-free solution worth considering.
