Scientists have found a way to turn on deep sleep at will using a machine that magnetically stimulates the brain.
A device worn on the head could in squeeze the benefit of eight hours’ sleep into just two or three hours.
Scientists in the US used a technique called transcranial magnetic stimulation (TMS) to induce slow waves – indicative of the deepest phase of sleep and essential for learning ability and mood, in a group of sleeping volunteers.
