Weighted blanket effect on melatonin (IMAGE)
Caption
A new study from Uppsala University shows that using a weighted blanket at bedtime increases melatonin in young adults. 26 young men and women have been examined if the bedtime use of a weighted blanket increases the production of sleep-promoting and anti-stress hormones like melatonin and oxytocin. In addition, they investigated whether the bedtime use of a weighted blanket (12% of participants' body weight) reduced the activity of stress systems in the body. To this end, saliva was collected repeatedly from participants while they were covered with either a weighted or a light blanket to measure melatonin, oxytocin, cortisol, and the activity of the fight and flight sympathetic nervous system.
