~10% of body weight, heat tradeoffs, and who should skip deep-pressure bedding

Weighted blankets are a physical sleep experiment: deep pressure helps some anxious sleepers and overheats others. Evidence for insomnia is mixed. This buying guide covers the 10% heuristic, Gravity vs generics, and why hot sleepers should fix temperature first.

Evidence

Emerging Research

Small trials on anxiety and sleep are mixed. Deep-pressure stimulation is the proposed pathway. It will not treat apnea or replace CBT-I.

Subjective ‘I fall asleep faster’ is a valid keep/return criterion.

How to Buy

Anecdotal

Gravity is the brand that mainstreamed adult blankets; cheaper generics use the same glass beads. Check return windows — this is polarizing.

Hot sleepers: cooling mattress or lighter quilt first (sleep-cooling guide). Do not stack a 20 lb blanket on a 72°F room.

Safety

Moderate Evidence

Infants: no. Respiratory disease, claustrophobia, and limited mobility: skip or ask a clinician. Pets will also have opinions.
