Everything you need to know about weighted blankets

This guide covers the science behind weighted blankets, what they're made of and how to select the perfect blanket for you!

DORMU: Weighted Blankets, Pillows, and Bedding

1. How do weighted blankets work?

As the name suggests, weighted blankets are quite literally weighted! They are heavy blankets that typically weigh between 7 kg and 12 kg, or 15 lb and 25 lb if you prefer imperial.

Weighted blankets work by providing gentle pressure across the body, providing the same sensation as being hugged, which is effective in reducing anxiety and promoting a deeper and more restful sleep.

This hug sensation is known in the scientific community as deep pressure stimulation and it’s responsible for creating a shift in a number of hormones that are responsible for regulating mood and sleep.

↓ Cortisol

Cortisol regulates a wide range of biological processes including metabolism, immune response and stress.

As with most hormones, it should follow a circadian rhythm. High cortisol blood levels are present when you wake up in the morning, useful for keeping you alert, and low levels are present in the evening, which help you relax and enter a peaceful sleep.

The challenge for most people, however, is that their cortisol level does not follow a normal trajectory. Cortisol is often too high in the evening, making you feel nervous, temperamental and stressed, impeding a good night’s sleep.

DORMU’s weighted blankets counter this by facilitating a reduction in cortisol to a healthy level, which in turn reduces late-night stress and anxiety.

University of Massachusetts at Amherst

"63% of subjects reported a reduction in anxiety after using a weighted blanket, and 78% reported calming effects."


Serotonin is known as the happy hormone and for good reason!

Elevated levels can drastically improve one’s mood and give that feel-good factor! Conversely, depleted levels can leave us feeling depressed, anxious, and can cause difficulty sleeping.

Most depression medications work by increasing our serotonin levels, but you can naturally boost serotonin levels through regular exercise, a healthy diet and a weighted blanket!

International Journal of Neuroscience

"Serotonin levels in test subjects increased by 28% following deep pressure stimulation."


↑ Melatonin

Melatonin is the hormone is responsible for facilitating the onset of sleep.

During the day, light suppresses this melatonin, keeping you alert. As night falls and natural light exposure decreases, the production of melatonin ramps up, telling your brain it’s time to sleep.

Even if you are sleep-deprived, it’s very difficult to fall asleep without elevated levels of this hormone, a common occurrence thanks to exposure to artificial light before bedtime.

The use of weighted blankets has been shown in studies to increase our melatonin levels, making it the perfect bedtime partner!
