The first-ever deep sleep enhancer invented by the researchers at the ETH Zurich passed the first clinical study, proving its effectiveness. The so-called SleepLoop System stimulates slow brain waves by playing specific sounds at specific times.
The wearable audio device in the form of a headband with electrodes and a microchip can recognize slow-wave brain activity characteristic of deep sleep, and it‘s timed to play stimulating sounds to make slow waves more synchronized and longer-lasting.
But why all the trouble to boost only one aspect of sleep?
Deep sleep is considered to be the most vital sleep stage in terms of physical recovery and brain regeneration. It’s also essential in preventing cardiovascular issues and boosting memory. However, unfortunately, many don’t get to enjoy a healthy amount of deep sleep.
One of the most deep-sleep-deprived groups out there is the elderly. Their biorhythm changes with aging, and deep sleep duration gets shorter and shorter. Because of this, the overall quality of sleep goes downhill for those over 65.
With this in mind, researchers chose 33 participants between the ages of 60 and 80. All were required to wear the SleepLoop System at night for four weeks.
The study was relatively simple, comparing deep sleep duration with and without stimulation. Still, the results published in the journal Communications Medicine were mixed.
While 16 participants managed to get more deep sleep while wearing SleepLoop, others were less susceptible to auditory signals. There were also some participants that didn’t experience any change whatsoever.
Scientists are now focusing on what causes these individual differences before the system hits the shelves. One thing is for sure, though — whether the system works for you has nothing to do with your well-being during the day.
Additionally, this device likely won’t be available as one of the OTC sleep aids, and, unlike herbal mixes and CBD products, it’ll most probably require a doctor’s prescription.
