Unlike similar products, Warmies don’t have a removable heat pack inside; instead, they are filled with natural grains that heat up when you put them in the microwave. What really separates Warmies from the rest, though, is that they contain dried French lavender, which is not only soothing to smell, but can potentially act as a natural sleep aid, according to research.

While Warmies are safe for all ages (make sure kids are doing so under proper adult supervision), they can help adults looking to soothe minor aches, stress, and other ailments. Each time they’re warmed up to specifications, expect the heat to last for around 40 to 45 minutes.

Humans aren’t the only ones who need some added warmth and stress reduction every now and then. Check out these heated plush toys for dogs.

And if needed, you can put your Warmie in the freezer for two to three hours (in a sealed freezer bag) and use it as an ice pack.

Simply warm the stuffed animal in the microwave for up to 1 minute (microwaves vary, adjust time accordingly, adult supervision required, product will burn, wipe clean with a damp cloth, do NOT saturate).
