Deeper Sleep Starts With Total Darkness
Frequently Asked Questions
Why does complete darkness improve sleep quality?
Light is the primary environmental signal that regulates the human circadian rhythm. Even small amounts of light detected through closed eyelids suppress melatonin production in the pineal gland ā the hormone that signals the body it is time to sleep. Research from Oxford University found that sleeping in complete darkness improved sleep onset speed and total sleep duration compared to sleeping with ambient light exposure.
Will it put pressure on my eyelashes or eyelids?
No. The 3D contoured cavity creates a space around the eyes so the mask rests on the cheekbones and forehead rather than on the eyelids or lashes. This makes it particularly suitable for people who have had eyelash extensions or who find flat masks uncomfortable after a few hours. The memory foam moulds to the contours of your face over time for an increasingly personalised fit.
Is it suitable for shift workers who sleep during the day?
Yes. This is one of its most valuable use cases. Shift workers are exposed to daylight during sleep hours, which significantly disrupts circadian rhythm and melatonin production. A high-quality blackout sleep mask is consistently recommended by sleep medicine specialists as the single most cost-effective intervention for improving daytime sleep quality in shift workers.
How do I clean the sleep mask?
Hand wash in cool water with mild soap or gentle detergent. Do not machine wash as this can damage the memory foam and elastic components. Gently squeeze out excess water without wringing, reshape the mask, and allow to air dry flat away from direct sunlight or heat. Regular cleaning every 1 to 2 weeks removes skin oils and product buildup that reduce the fabric softness over time.
