Weighted Blankets for Sleep: The Complete Guide
~10% of body weight, heat tradeoffs, and who should skip deep-pressure bedding

- ·People who like feeling tucked in
- ·Cool-room sleepers after caffeine and light are fixed

Evidence
Emerging ResearchSmall 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
AnecdotalGravity 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 EvidenceInfants: no. Respiratory disease, claustrophobia, and limited mobility: skip or ask a clinician. Pets will also have opinions.
