A well-designed weighted blanket is an effective tool to calm and soothe a child. They were typically used as therapeutic aids to help people with dementia, autism, and other mental ailments in the past. As a result, they have become a very popular product in the modern marketplace. These blankets are also extremely useful for promoting healing in infants, children, seniors, and people with poor posture or injuries. They work to alleviate tension in the muscles and to encourage restful sleep. The idea behind weighted blankets is to provide a calming effect through the use of tension-relieving metal strips. These strips are generally made from either nylon or gold. They can be placed around the head, neck, chest, or shoulders. These strips' presence triggers serotonin production, which has a soothing and relieving effect on the brain. Over the long term, this lowers blood pressure and improves a person's overall mood. One of the main uses of weighted blankets is to promote sleep. Sleep medicine is particularly effective when administered during the night. Nurturing sleep is vital for people who need help staying asleep and those who suffer from psychiatric disorders. It helps prevent feelings of fatigue during the day. For these and many other reasons, including reducing tension and promoting healthy sleeping habits, weighted blankets are valuable sleep medicine products. They are also beneficial to those with medical conditions because they can be used to reduce swelling during the recovery process. The addition of pressure points such as aches in the shoulder, neck, arms, and legs can increase pain and discomfort. In some cases, plastic pellets or soft polyester balls are used to provide this sensation. However, the addition of a weighted blanket can help to alleviate some of these symptoms. Many people find that they can fall asleep with the weighted blankets because they no longer feel the discomfort associated with having their arms and legs on a rigid plastic mattress. In addition to making it easier to sleep on a bed, the blankets also allow someone who has suffered from back surgery to loosen up enough to get some much-needed rest. Finally, adding a weighted blanket to a regimen of relaxation therapy can have a beneficial impact on anyone with excessive anxiety or depression. Anxiety is known to increase cortisol levels, which is one of the brain's chemicals that increases heart rate and blood pressure. High cortisol levels can have a significant impact on mood and physical well-being. Fortunately, weighted blankets can lower the amount of stress hormone in a person's body by stimulating serotonin production, known as the feel-good chemical in the brain. Research has shown that serotonin's chronic stimulation by weighted blankets leads to a feeling of well-being and positive thoughts and emotions.
