Exhausted... but your brain won't switch off?
Night Switch™
Your brain isn't broken — it's stuck in "on mode."
Modern life floods your eyes with artificial light at night — phones, TVs, overhead lighting — telling your brain to stay alert, stay awake, it's still daytime.
For thousands of years, sunset triggered melatonin to rise and your nervous system to slow down. That signal never arrives anymore. So even when your body is exhausted, your brain never gets the message to power down.
Red light is the one wavelength that doesn't tell your brain it's daytime.
Red light therapy, particularly at wavelengths of 660nm and 850nm, has been studied for its effects on circadian rhythm regulation and relaxation.
660nm (Red Light) — Research suggests this wavelength penetrates the skin, supports cellular energy production (ATP), and may help increase melatonin production, supporting sleep onset.1
850nm (Near-Infrared Light) — Studies indicate this deeper-penetrating wavelength supports circulation and relaxation that may aid sleep readiness.2

We're not just a company.
We're a husband-and-wife team with five kids. We know what it's like to run on no sleep — the late nights, the early mornings, the exhaustion that creeps into everything else.
We built NightSwitch because we needed something simple that actually helped us wind down, not another app or supplement to add to the routine.
Everything you need to know about NightSwitch
Frequently Asked Questions
Is it safe for my eyes?
Yes. NightSwitch is designed for closed-eye use, held near your face. The 660nm red light is gentle and non-damaging — the same wavelength used in professional red light therapy. Always keep your eyes closed during use.
How soon will I notice a difference?
Most people notice they feel calmer and fall asleep more easily within the first few nights. For best results, use NightSwitch consistently as part of your wind-down routine for at least 2 weeks.
What if it doesn't work for me?
No problem. NightSwitch comes with a 60-night risk-free trial. If it doesn't help you sleep, send it back for a full refund — no questions asked.
Can my partner use it too?
Absolutely. NightSwitch is designed for individual use but there's nothing stopping two people from sharing it as part of their evening routine. One device, two better sleepers.
