The Science and Benefits

Do you want to know more about the science behind weighted blankets? Weighted blankets have been researched extensively and have been shown to increase serotonin and melatonin while decreasing cortisol. Well, what exactly does that mean? Read on to discover the science behind weighted blankets.


Serotonin is a chemical that is created in our body naturally that helps to regulate mood, social behavior, appetite, digestion, sleep, memory, and sexual desire. When people have low levels of serotonin, it can sometimes cause depression and anxiety. Increasing the body’s serotonin levels can produce feelings of well-being and happiness.


Melatonin is a chemical hormone that is naturally produced in the body that tells us when it’s time to sleep and when it’s time to wake up. Melatonin is created by a gland in the middle of your brain, and increased levels of melatonin can signal the body to sleep, while decreased levels could result in insomnia and other sleep problems.


Cortisol is a stress hormone. When we experience stress at work, school, or home, our brain may perceive it as a threat, which can increase our cortisol levels. The best way to manage our stress levels is to get adequate sleep

The Weighted Evolution blanket is engineered using DPS or Deep Pressure Stimulation. DPS is widely studied by researchers and is also recommended by occupational therapists and doctors

What is deep pressure stimulation?

Broken down in layman's terms, Deep Pressure Stimulation (DPS), triggers the Parasympathetic Nervous System (PSNS) to switch on. The PSNS, also known as your ‘rest and digest’ system, is designed to bring a sense of calm and peace to the mind and body. By triggering the PSNS with DPS, you are telling your body to calm itself down. Its like a hug from a loved one. 

Many weighted blankets fail to take advantage of DPS by over-filling the blankets with unnecessary insulation in large pockets, which inhibits the effect of DPS. We specifically designed the Weighted Evolution blanket with small diamond pockets to have minimal insulation, allowing the glass sand beads to make more direct contact with your body thus initiating DPS quickly and effectively.
