Exposure to red light before bedtime may help regulate sleep patterns by supporting the production of melatonin, the hormone responsible for sleep.
Unlike blue light, which can disrupt circadian rhythms, red light has a calming effect on the body and mind. This supports the natural sleep-wake cycle, making it easier to fall asleep and achieve restful, deeper sleep. Regular use of red light therapy before bed may improve overall sleep quality and help those with sleep disorders.
