Is a Weighted Blanket Worth It? What the Evidence Actually Says

The evidence for weighted blankets centres on deep pressure stimulation — the same mechanism as a firm hug. It's well-established in occupational therapy contexts and has reasonable support in general sleep research. Emma's version uses glass beads over plastic pellets, which distribute more evenly and don't shift noisily during movement. The 6kg version is appropriate for most adults — the general guideline is approximately 10% of body weight.

Waking to a gradual light increase rather than an abrupt alarm works with your body's natural cortisol response rather than against it. Lumie is the original and most clinically studied brand in this space — their devices have been used in NHS-affiliated research. The sunrise simulation begins 30 minutes before your alarm time, gradually brightening to trigger a more natural waking state. Particularly effective in UK winters when mornings are dark until late.

Dodow projects a pulsing light onto the ceiling and guides you to synchronise your breathing with it — slowing your breathing rate from roughly 11 breaths per minute to 6. Slower breathing activates the parasympathetic nervous system and lowers alertness. The mechanism is well-established; whether the device outperforms simply practising slow breathing independently is debatable. But for people who struggle to self-regulate breathing without a guide, it genuinely helps.
