Exhausted... but your brain won't switch off?
Night Switch™
Your brain isn't broken - it's stuck in "on mode".
Most people think they have a sleep problem. But what they actually have...is a signal problem.
Your brain relies on light to know when its time to wind down.
The problem?
Modern life floods your eyes with artificial light at night - phones, TV's, overhead lighting - telling your brain:
STAY ALERT. STAY AWAKE. IT'S STILL DAYTIME.
So when you finally get to bed...your body is tired, but your brain is still fully switched on.
Thats why you can feel exhausted - and still not be able to sleep
switch off tonight
YOUR BRAIN NEEDS DARKNESS...BUT YOU'RE NOT GETTING IT.
For thousands of years, the sun setting triggered a powerful biological response:
- Melatonin rises
- Your nervous system slows
- Your brain prepares for sleep
But now?
That signal never arrives.
Which means your brain never fully powers down.
RED LIGHT IS DIFFERENT
It's the only type of light that tells your body:
IT'S TIME FOR SLEEP.
THAT'S WHERE NIGHT SWITCH COMES IN.

The Science Behind the Sleep
WHAT IS RED LIGHT THERAPY?
Red light therapy, particularly at wavelengths of 660nm and 850nm, can improve sleep by influencing the body’s natural circadian rhythms and promoting relaxation
660nm (Red Light)
This wavelength penetrates the skin, stimulating cellular energy production (ATP) and promoting healing and relaxation. It helps reduce inflammation and increases melatonin production, aiding in sleep onset and quality.
850nm (Near-Infrared Light):
This deeper-penetrating less visible wavelength supports muscle recovery, reduces pain, and improves blood circulation. Enhanced circulation can lead to better oxygenation of tissues, which supports overall body relaxation and readiness for sleep.
Combining these wavelengths can provide a comprehensive approach to improving sleep quality, making it easier for the body to relax and stay asleep through the night.
