Red light therapy is the answer to a good night’s sleep, says expert

Light therapy has had a major surge over the years, with the rise of the best LED face masks no longer being confined to the spa or dermatologist offices. LED light therapy, like red light, can have amazing effects on the skin, including less wrinkles, reduced inflammation and treating acne… but did you know that it can also help you sleep better?

Before I get into the details, it’s important to understand what red light therapy is. It’s a non-invasive treatment that emits wavelengths of light that penetrate the skin and are absorbed by the skin’s receptors. Chances are you’ve seen red lights before as it’s pretty common in LED face masks, but this light therapy isn’t just for the face: it can be used on other parts of the body and you can find full light panels that you can sit or stand in front of.

In addition to improving your skin, experts at Happy Beds have found that red light therapy can also help with your sleep quality. To find out more, I spoke to Happy Beds who explained the four sleep-related benefits of red light therapy. 

1. Red light can produce the sleep hormone

According to experts at Happy Beds, red light can help stimulate the production of the sleep hormone, melatonin. Melatonin is naturally produced by the body as it gets closer to bedtime, in keeping with your circadian rhythm. While it’s something that’s made naturally by the body, it can also be stimulated by external factors such as limiting screen time, exercising and eating certain foods.

Red light is another stimulus that can help produce melatonin, which in turn, helps you fall asleep. Happy Beds said that “in fact, one study found that after 14 days of 30 minutes of red light therapy each night, participants recorded higher melatonin levels and overall better sleep quality.”

2. Red light can regulate your sleep cycle

As previously mentioned, red light can help with the production of melatonin. By doing this, red light therapy can also better regulate your sleep cycle or circadian rhythm. To take advantage of this, Happy Beds recommended “shutting off your devices that emit blue light one to two hours before bed, and changing lights to red.” The experts suggest that it can help you fall asleep and wake up easier the next day.

However, Happy Beds say that it’s important to choose the right brightness of red light. If it’s too bright, this could have the opposite effect and hinder your melatonin production, so it’s important to choose a darker red light when you’re winding down for the night on your best mattress.

3. Red light can reduce grogginess in the morning

It’s fairly common to experience grogginess or sleep inertia when you wake up in the morning, especially if you’ve snoozed your alarm or woken up abruptly to its noise. But red light therapy has been reported to reduce that feeling. Happy Beds explained how a recent study found that a control group exposed to red light through closed eyes via a face mask were less sleepy when waking. This was compared to a group that didn’t use red light and were exposed to dim lights instead.

4. Red light can ease sleep disorders

The main reason people use light therapy is to treat skin concerns. Red light is one of many different coloured lights you can use in a face mask or light panel, and it’s best for reducing inflammation, promoting blood circulation and giving skin a healthier glow.

With this in mind, Happy Beds found that red light therapy can be an effective treatment for psoriasis and other skin issues like acne. As explained by Happy Beds, “sleep disruption is a common side effect of psoriasis. Studies have shown that sleep disorders are frequent during psoriasis flare-ups.” So, if red light can help treat psoriasis, this can result in a reduction of flare-ups and other symptoms which can help improve your sleep quality.
