How Does Red Light Therapy Improve Melatonin Production?

Red light, particularly in the 600–700 nm wavelength range, is like a signal to the brain to start relaxing. This stimulates the body’s natural rise in melatonin, promoting better sleep quality.

Can Hyperbaric Oxygen Therapy Help With Sleep Apnoea?

People are turning to hyperbaric oxygen therapy for sleep apnea because, as it increases the amount of oxygen in the body, it helps reduce inflammation in the airways and supports more restful breathing at night.

Are These Treatments Safe for Long-Term Sleep Issues?

Yes, both are considered safe when used as directed. Red light therapy can cause mild redness or eye sensitivity if unshielded, while HBOT sessions should be supervised to avoid complications like sinus damage or ear pressure changes. Always consult a healthcare professional first, especially if you have underlying health conditions, to ensure the treatment is right for you.

How Many Sessions Are Needed to See Sleep Improvements?

People often see sleep benefits after 4–6 weeks, if they consistently attend treatments 2–3 times per week. For significant improvements, it’s recommended to do a total of 20 to 60 sessions.
