Why Jennifer Aniston Calls a Weighted Blanket a Game-Changer

Because she says it helps her sleep. In a March 2023 interview with Real Simple, Jennifer Aniston put a weighted blanket near the top of her bedtime kit: "I have a weighted blanket and that is another game-changer," she said, adding that she got one about two years earlier and that it is "very helpful for sleep." She also named soft sheets and silk pillowcases. That is one public voice describing a tool, not a clinical trial. Still, her quote lines up with a wider interest in deep pressure and the nervous system, and with research that has tested weighted blankets for insomnia in a very different population.

What does her broader wind-down look like?

A year earlier, in an April 2022 interview with SELF, Aniston walked through the routine she aims for when work allows. Screens go off first. Her phone goes into the kitchen or the bathroom. She walks the dogs, locks the doors, and tries to be in bed around 11pm. She washes her face. When she is lucky, she takes a hot bath. Then come stretches, some yoga, meditation, and prayer.

"When I have the luxury of maintaining my routine, it's everything," she told SELF. She described herself as a night owl who has had to work at consistency, and she said you cannot make up lost weekday sleep on the weekend because sleep is when the body does repair work. After a stretch of sluggishness that spilled into eating and exercise, she raised sleep with her doctor and made it the first question on her list. Coverage in outlets such as USA TODAY and Healthline has also noted that she has discussed insomnia and seeking medical advice. She has not published sleep-lab data, and nothing here is a diagnosis.

The pattern that emerges is ordinary and useful: remove screens, protect a consistent bedtime when you can, and stack a few calming cues. The weighted blanket sits inside that stack, not instead of it.

What does research say about weighted blankets and sleep?

Aniston was not in these studies. Treat the science as context for the tool she named, not as proof that her routine works for everyone.

The clearest randomized evidence comes from a Swedish trial published in the Journal of Clinical Sleep Medicine in 2020. Bodil Ekholm, Stefan Spulber, and Mats Adler enrolled 120 adults who already had clinical insomnia plus a psychiatric diagnosis such as major depression, bipolar disorder, ADHD, or generalized anxiety. For four weeks, one group slept under a chain-weighted blanket (8 kg, or 6 kg if 8 kg felt too heavy). The control group used a light 1.5 kg chain blanket.

On the Insomnia Severity Index, the weighted-blanket group improved far more than controls (P < .001; Cohen's d = 1.90). About 60% of weighted-blanket users cut their ISI score by half or more, versus 5.4% in the control group. Remission (ISI of 7 or less) was 42.2% versus 3.6%. Actigraphy also pointed to better sleep maintenance and higher daytime activity, with lower fatigue, depression, and anxiety symptoms. No serious adverse events were reported. In an American Academy of Sleep Medicine summary of the work, Adler suggested that deep pressure may increase parasympathetic activity and reduce sympathetic arousal, a calming shift that feels similar to massage or acupressure.

Caveats matter. This was a psychiatric insomnia sample in Sweden, not a celebrity bedroom in Los Angeles, and not a general-population trial. The effect size was large in that group, but it does not prove that any one famous person's blanket "cured" anything. Use it as support for the idea that deep pressure can help some people with insomnia symptoms, then decide with your own clinician if sleep problems persist.

What about heat on humid nights?

Pressure and heat are not the same problem. The National Sleep Foundation advises keeping the bedroom cool and notes that experts often treat about 60 to 67°F as a useful range for sleep. Related sleep-environment guidance commonly cites a similar cool-room target around the mid-60s°F.

Many tropical nights sit well above that. In Singapore, for example, overnight temperatures and humidity often make a heavy textile feel sticky long before it feels calming. If you like the idea of a weighted blanket but run hot, look for designs built to shed heat, such as a cooling weighted blanket with a phase-change or breathable knit, rather than a thick winter throw. The specifications page explains how one breathable, deep-pressure design approaches that trade-off. Comfort still comes first: if the weight feels wrong, a lighter option or a different wind-down tool may suit you better.

What can you try without turning this into medical advice?

Borrow the structure of Aniston's routine, not her fame.

• Park the phone away from the bed. Kitchen or bathroom counts. The goal is fewer mid-night checks.
• Protect one consistent lights-out window when your schedule allows. She aims near 11pm; your number should match your wake time and life.
• Stack low-arousal cues. Face wash, a warm bath when you have time, stretches, brief meditation or quiet breathing. Skip stacking every trend at once.
• If you want deep pressure, try weight that still breathes. On humid nights, prioritize airflow and a cool room before adding mass. A cooling weighted blanket is one option among many.
• See a clinician for ongoing insomnia. Aniston's own story started with a doctor conversation. That is the right escalation when sleep stays poor for weeks or daytime function slips.

A public quote is a starting point. The Swedish trial shows deep pressure can move insomnia scores in a defined clinical group. Your bedroom temperature, humidity, and health history decide whether a weighted blanket belongs in your kit at all.
