Weighted Sleep Mask
Nodpod combines light blocking with Deep Pressure Touch (DPT). This dual-action approach not only optimizes the circadian rhythm through darkness but also lowers cortisol levels through gentle pressure, aiding sleep onset.
Quality & Materials
Filled with scentless BPA-free polyethylene beads. One side is cooling jersey cotton, the other is warm microfiber fleece.
Evidence & Testing
DPT is supported by research for anxiety reduction, though specific RCTS on this mask's light-blocking efficacy are limited compared to Manta.
Brand Transparency
The company is clear about its bead materials and the 'scent-free' nature of the product, which is vital for sensitive sleepers.
Value Assessment
At $34, it is a premium product but serves two functions (weighted therapy + light blocking), justifying the cost.
Why Not Alternatives?
Most weighted masks use elastic straps that can cause tension headaches; Nodpod is strap-free and uses a pull-through design that stays in place via gravity and friction, making it better for side sleepers.
