Better Sleep, Relaxation and Migraine Support
What are Blue Light Free Light Bulbs?
Standard household lighting contains approx 35% blue light, office lighting up to 45%. Your brain, via your eyes, perceives this light as daytime, triggering alertness and making it harder to relax or sleep.
Blue light free bulbs support your natural circadian rhythm (your body’s sleep-wake cycle) and available in SLEEP Red or RELAX Amber.
Colour alone is not proof: many cheap red or amber bulbs are standard white LEDs behind a tinted cover, so always check the label says 100 percent blue light free.
Harvard Medical School, The Sleep Charity and Cerebra which specialise in neurological conditions recommend blue light free lighting in the hours before bed.
What Lighting is Best for Migraines?
A very specific band of green light, around 520-530nm (narrowband), is the exception.
Harvard Medical School researcher Dr. Rami Burstein found this narrow band of green light reduced migraine pain by around 20% in sighted participants, while white, blue, amber and red light all tended to worsen symptoms.
A follow-up University of Arizona study went further, tracking daily green light exposure over 10 weeks: average migraine days per month dropped from 7.9 to 2.4 for episodic migraine sufferers, and from 22.3 to 9.4 for those with chronic migraines.
The research is still early and considered experimental, but for something with no reported side effects, it’s a compelling option worth exploring alongside your usual migraine care.
Are CHIRYŌ Bulbs Safe for Children and Neurodivergent People?
Yes. CHIRYŌ Healthy Lighting bulbs and lamps are flicker free, low EMF and CE marked, so they are safe for children, adults and pets, including people with ADHD, autism, sensory sensitivity and photophobia.
Flicker is a common cause of eye strain and discomfort from standard LEDs, and our bulbs have none.
SLEEP Red and RELAX Amber also have 100 percent blue light removed, so evening light is aligned with relaxation, and does not signal daytime to the brain.
What is Circadian Lighting?
Circadian lighting should be engineered to remove 100% blue light, zero flicker and be low in EMF, to work with your body’s natural 24-hour sleep-wake cycle, rather than disrupting it.
Bright, blue-rich light in the morning and daytime supports alertness, while blue light removed red or amber from sunset onwards avoids suppressing melatonin, the hormone that signals your body it’s time to sleep.
Using the right light at the right time of day is one of the simplest ways to support better sleep naturally.
