Swiss scientists have developed a helmet to improve sleep quality. This is called the Sleep Cycle. The device uses sound stimulation synchronized with the rhythms of the brain.
Previously, scientists found that the brain produces a slow delta rhythm (0.5-4 Hz) during deep sleep. It turns out that these waves can be protected and amplified by sounds synchronized with them. These sounds are the sounds a person listens to during sleep.
Therefore, SleepLoop devices should be worn before going to bed. It consists of a bandage, electrodes and a microchip. They constantly measure the activity of the sleeper’s brain. These data are analyzed in real time. When a person has the characteristic phases of deep sleep brain rhythms, sound signals begin to be produced. These sounds shouldn’t wake him up.
The device has already been tested on humans. They used it every night for four weeks. For some, sleep has improved. Scientists have developed the device and want to bring it to market in the clinical market. It can only be purchased by prescription.
