Why should I avoid weighted blankets with polyester fill?

When it comes to weighted blankets specifically, a polyester fabric often described as ‘minky’ has gained much popularity. These so-called minky, plush fabrics create an immediate draw because they are soft and cuddly. Although soft, these plush fabrics are 100% polyester and therefore do not breathe very well, meaning they can make for a hot, stuffy night. For a child or adult who is hot-natured, a polyester blanket can end up being uncomfortable to sleep with. Any allergies or sensitive skin conditions can also be affected by synthetic fabrics like polyester.
