How do heavy blankets have to do with deep sleep?

The reason for the increase in the sale of heavy blankets is not just a trend; it is said to have a positive effect on sleep.

Sleep and heavy blankets

According to a study conducted at the University of Uppsala in Sweden, heavy blankets increase the production of hormones that cause deep and restful sleep.

Swedish researchers found in the study that those who wore heavy blankets while sleeping had more than 30 percent higher levels of melatonin than those who wore a normal blanket.

The melatonin hormone is naturally released by the brain every night to make a person feel tired and set up our internal clock.

Heavy blankets are said to relax the nervous system, reduce some symptoms of anxiety, such as a rapid heartbeat or rapid breathing. Your heart beats faster when you’re stressed which stops melatonin production.

Researchers from The University of Uppsala in Sweden examined 26 people for two nights. In one night, participants slept wearing heavy blankets, while the other night they used a normal sheet.

The study, published in the Journal of Sleep Research, compared the weight of the blankets used with the weight of the participants. The weight of blankets was 12.2 percent of the participants’ weight, while the weight of the normal sheets was 2.2 percent.

The participants slept around 10 p.m. and their saliva samples were taken every 20 minutes until 11 p.m. The results showed that melatonin production was 32 percent higher in those who slept wearing heavy blankets at the end of the hour.
