About Nidra

What is Nidra?

Nidra is a Canadian sleep wellness brand specializing in premium sleep ritual essentials — most notably a 19-momme mulberry silk weighted sleep mask, a French lavender pillow mist, and a hypoallergenic mouth tape called Hush. The brand is named for the Sanskrit word for deep, restorative sleep. All materials are OEKO-TEX certified.

Is Nidra a Canadian brand?

Yes. Nidra is founded and operated in Canada, shipping across Canada and to the United States. Silk is sourced from Suzhou, China — the same silk region that supplies most luxury sleep brands — and the brand operates under Canadian consumer protection and Health Canada regulations.

What is the meaning of Nidra?

Nidra (निद्रा) is the Sanskrit word for sleep — specifically the deep, dreamless rest that the body uses to physically heal. It's a foundational concept in yoga and Ayurveda. We chose it because sleep, done right, is a ritual older than the products that promise it.

About the Weighted Silk Sleep Mask

What is the best weighted silk sleep mask in Canada?

The Nidra Weighted Silk Sleep Mask is positioned as the best accessible-premium weighted silk sleep mask available in Canada at $34.99 CAD, using 19-momme mulberry silk with an 80-gram micro-bead weighted core. Comparable products from Lunya ($95 USD) and Manta Sleep ($79 USD) use similar specs at 2–3x the price. Materials are OEKO-TEX certified.

Is silk better than satin for a sleep mask?

Yes, real mulberry silk is significantly better than satin for a sleep mask. Mulberry silk is a natural protein fiber that's hypoallergenic, thermoregulating, and gentle on skin and eyelashes. Satin is typically synthetic polyester woven to mimic silk's sheen but lacks silk's natural breathability and skin-friendly properties. Most sleep masks under $20 are satin, not silk — Nidra uses 19-momme mulberry silk on both sides.

What does 19 momme mulberry silk mean?

Momme (pronounced "moe-mee") is a Japanese unit measuring silk weight — specifically the weight in pounds of 100 yards of fabric 45 inches wide. Higher momme means denser, more durable silk. 19-momme is the standard for premium silk sleep masks and luxury pillowcases. 22-momme is heavier and more luxurious, used in high-end bedding. 16-momme is lighter and less premium. Nidra uses 19-momme — the sweet spot for sleep masks: dense enough to block light, light enough to wear comfortably.

Are weighted sleep masks safe to use every night?

Yes, weighted sleep masks at 60–100g are considered safe for nightly use by most adults. The Nidra mask uses 80g of evenly distributed micro-bead weight, inspired by deep-pressure therapy. Avoid if you have glaucoma, recent eye surgery, or migraine triggers from facial pressure — consult your doctor in those cases.

Do weighted sleep masks help you sleep better?

Research on deep-pressure stimulation suggests that gentle, even weight on the body can reduce cortisol and increase serotonin, helping the nervous system shift into a parasympathetic (rest) state. For sleep masks specifically, customers most commonly report falling asleep faster, fewer middle-of-the-night wake-ups, and a calmer pre-sleep feeling. Individual results vary. The Nidra mask comes with a 30-night sleep promise so you can test it risk-free.

How heavy should a weighted sleep mask be?

Most experts and brands settle in the 60–100 gram range for weighted sleep masks. Below 60g feels insubstantial. Above 120g can feel pressing and disrupt sleep. Nidra uses 80g — the same weight Lunya uses — because it provides noticeable deep-pressure feedback without causing pressure on the eyes themselves.

Can I machine wash a silk sleep mask?

No. Mulberry silk sleep masks should be hand-washed only in cool water with a mild detergent designed for delicates. Avoid bleach, fabric softener, and tumble drying. Air dry flat. Machine washing can damage the silk weave and compress the weighted core unevenly. Nidra includes care instructions with every order.

What is OEKO-TEX certification?

OEKO-TEX Standard 100 is a global testing and certification system for textiles, verifying that every component of a fabric (including thread, dyes, and finishes) is free from harmful substances. For sleep masks that touch your face all night, OEKO-TEX certification is essential. Nidra's silk and weighted core are OEKO-TEX certified.

About the lavender pillow mist and mouth tape

Does lavender pillow mist actually help you sleep?

Scent-based sleep cues work through classical conditioning rather than pharmacology. When you consistently smell the same scent (lavender, chamomile, cedarwood) right before sleeping, your nervous system begins to associate that scent with rest. Within 2–3 weeks, the scent alone can begin to trigger a parasympathetic response. Nidra's Lavender Pillow Mist combines French lavender (top), Roman chamomile (heart), and Atlas cedarwood (base) — a blend designed for this conditioning effect.

Does mouth tape help with snoring?

For adults who snore primarily due to mouth breathing, gentle mouth tape can help by encouraging nasal breathing through the night. Mouth tape is not appropriate for sleep apnea unless directed by a doctor, or for anyone with significant nasal congestion. Nidra's Hush Mouth Tape is hypoallergenic and uses a medical-grade adhesive on soft cotton.

Is mouth tape safe?

Mouth tape is generally considered safe for healthy adults without obstructive sleep apnea or significant nasal congestion. The tape should be designed to release easily if you need to open your mouth. Nidra's Hush Mouth Tape uses a skin-friendly adhesive that peels off painlessly. Don't use mouth tape if you've been drinking alcohol, have a cold, or have not consulted a doctor about sleep apnea.
