According to the Sensory Processing Disorder Research Center, weighted blankets are "one of the most effective tools for helping those difficult to calm down, high energy sensory kids." They often are used for children, teens and adults with autism and other special needs. These blankets are specially made, most often with polypropylene pellets providing the weight.
How They Work
Research has found that deep pressure touch stimulation (DPTS) releases serotonin, a chemical in the brain that works as a neurotransmitter in the regulation of mood, sleep and sensory perception. Weighted blankets mimic DPTS and thus have a calming and soothing effect.
Weight Recommendations
Generally, the weight of the blanket should be equal to 10 percent of a person's body weight plus one pound. From there, weight can be added or subtracted based on personal preferences.
Use Them
Weighted blankets can be used at bedtime to induce sleep and left on overnight or for as long as the user wants or needs. If the blanket is used for a calming effect, it can stay on as long as needed. There are no ill effects of leaving a weighted blanket on for long periods of time.
Warnings
A weighted blanket should never be used as a restraint and should never be so heavy that the user cannot remove it himself.
