Similar Assertions

Cool white light bulbs, like some LEDs and CFLs, might mess with your sleep more than warm yellowish ones because they can reduce a sleep hormone called melatonin more strongly.

Changing your LED light from cool white to warm white in the evening can cut down how much it messes with your sleep hormones by over 99%.

Cool white LED lights might mess with your sleep more than old-style light bulbs because they affect your body's internal clock more, even if they look just as bright. Old incandescent bulbs are gentler on your circadian rhythm at night.

In healthy young guys, better-quality daylight-like LED lights don’t seem to change daily melatonin levels or brain performance like focus and memory — so upgrading light quality might not always boost health or thinking skills.
