When it comes to improving sleep quality, one of the most overlooked tools is actually something we all have access to: light. Exposure to natural light during the day plays a huge role in regulating your body’s internal clock, also known as your circadian rhythm.
Getting outside first thing in the morning is a great start. Allowing your eyes to take in natural sunlight early in the day helps signal to your brain that it’s time to be awake and alert. But did you know that afternoon sunlight matters, too? Stepping outside in the late afternoon or early evening provides a second signal to your circadian rhythm, reinforcing the natural day-night cycle and helping your body prepare for rest later on.
Of course, not everyone has the flexibility to catch those afternoon rays. If that’s the case, artificial light therapy can be a great alternative. Red light therapy, in particular, has been shown to support circadian rhythm and promote better sleep. The red and near-infrared wavelengths mimic the benefits of natural light exposure, making it easier for your body to wind down in the evening and fall asleep more easily.
So whether it’s a short walk outdoors or a few minutes of red light therapy, finding ways to give your body that extra dose of light can make a big difference in the quality of your sleep.
