Weighted blankets are specially designed blankets filled with materials like glass beads or plastic pellets, making them heavier than regular blankets. They are often used to provide a sense of comfort and security, mimicking the feeling of being hugged. This added weight can help some individuals feel more relaxed and may improve sleep quality. Many people use weighted blankets to manage conditions such as anxiety, autism, or ADHD. The pressure from the blanket is thought to stimulate the release of serotonin, a hormone that can enhance mood, and melatonin, which helps regulate sleep.
