I’m sure this will pique a lot of interest:
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.
A TMS device sends harmless magnetic signals through the scalp and skull and into the brain, where it activates electrical impulses.
