It's well known that certain wavelengths of light can trigger specific reactions in the brain. For instance, light exposure helps stimulate the release of serotonin — the " feel-good" hormone. Blue light, which has shorter wavelengths and higher energy, promotes alertness. While this can be beneficial during the day, too much blue light at night or during restful periods can disrupt our circadian rhythm.
Wait — our what?
Our circadian rhythm is the internal clock that regulates our sleep-wake cycle, repeating roughly every 24 hours. When this cycle is disrupted, it can negatively affect our mood, concentration, emotional regulation, and decision-making. In fact, research from Harvard Medical School links disrupted circadian rhythms to anxiety and depressive disorders. Blue light exposure boosts cortisol (the stress hormone) and reduces melatonin (the sleep hormone), making it harder for us to relax and rest properly.
So, how is red light different?
Red light, which has longer wavelengths and lower energy, has been shown to support relaxation and help the body wind down — especially when used in the evening. When used in the morning, it can also help reduce sleep inertia — that groggy, foggy feeling upon waking. Red light therapy is a proven, drug-free option for addressing sleep challenges, including insomnia, circadian rhythm disorders, depression, and seasonal affective disorder. Maintaining a healthy, consistent sleep pattern is one of the most powerful ways to reduce stress and support overall wellbeing.
Another powerful way to use red light therapy is as a meditative aid. Meditation is widely known for its mental and physical benefits — from improved concentration and mindfulness to a deeper sense of calm. Practicing meditation in front of your red light device helps you enter a peaceful, undisturbed mental space while your cells undergo gentle, restorative rejuvenation. それ ' s a beautifully holistic experience — mind and body working in harmony.
Top Tip:
Try incorporating 10 – 15 minutes of meditation with red light therapy into your daily routine. It can help you feel calmer, more focused, and less reactive to stress. Plus, there are no negative side effects — only a growing list of benefits that make it even more appealing.
