Try FlexBeam todayCircadian support
Light is one of the body’s most important signals for knowing when to be awake and when to sleep.
For more restful evenings
Red light therapy can support the body’s natural transition into rest.
Better overnight recovery
Red and near-infrared light affect the mitochondria and support cellular energy production.
Part of your evening routine
Use FlexBeam while reading, relaxing, or getting ready for bed.
Why does light matter so much for sleep?
Our bodies evolved in a world with bright daylight during the day and darkness at night.
But modern life looks very different.
We spend much of the day indoors and are exposed to artificial light and screens well into the evening.
This can make the signals that regulate our internal body clock less clear.
Blue and bright light in the evening can suppress melatonin and signal to the body that it’s still daytime. Red light affects this system differently and is better suited to the hours when the body is preparing for rest.
The right light at the right time is an important part of maintaining a healthy circadian rhythm.

Red and near-infrared light affect the body at the cellular level. Four mechanisms are particularly interesting:
Circadian rhythm and melatonin
Light plays a central role in regulating the body’s internal clock. Research is exploring how red light may support healthy melatonin levels and sleep-wake rhythms.
Calm and relaxation
Red light therapy can support the body’s natural transition from activity to rest. Research is exploring how red light affects the autonomic nervous system and signaling pathways involved in recovery and relaxation. This makes red light a natural choice when you want to wind down and prepare your body for sleep.
Overnight recovery
Sleep is the body’s most important time for repair, recovery, and renewal. Research shows promising results for red light in relation to sleep quality and deeper sleep.
Cellular energy
FlexBeam’s red and near-infrared light affects the mitochondria - the energy-producing structures within our cells - and may increase ATP production.
Deep sleep is the body’s most important recovery phase
Deep sleep is one of the most important stages for physical recovery. During this phase, the body repairs tissue, supports immune function, and restores energy for the day ahead.
Research on red light therapy shows promising results for sleep, including sleep quality and deep sleep.
FlexBeam combines red and near-infrared light, which affect the mitochondria and cellular energy production. Its wearable design makes it easy to incorporate FlexBeam into your evening routine, giving your body extra support as it transitions from activity to recovery.
The goal isn’t just more hours in bed. It’s more restorative sleep.

Make FlexBeam part of your evening routine
Sleep is about much more than waking up feeling refreshed.
It’s the body’s most important time for recovery, repair, and preparing for a new day. And light plays a key role in telling your body when it’s time to be active - and when it’s time to wind down.
With FlexBeam, you can easily make targeted red and near-infrared light part of your evening routine, creating a natural transition from the activity of the day to overnight recovery.
Support your circadian rhythm. Prioritize recovery. Sleep better.

Frequently asked questions
Yes. Research has explored how red light therapy may affect sleep quality, melatonin, and circadian rhythm.
For many people, evening use works well. If you feel more awake or energized after using FlexBeam, the FlexBeam guide recommends moving your session to the morning.
Deep sleep is an important part of the body’s physical recovery. Sleep as a whole also supports memory, hormone regulation, immune function, and the brain’s processing of information. Read our article on deep sleep.
Different wavelengths penetrate tissue at different depths. FlexBeam combines red and near-infrared light to deliver targeted red light therapy directly to the body.
