Why Your Hubby Sleeps Through Anything

Heavy sleepers sleep through almost anything because their brains are better at fending off noises, researchers say. Scientists as Harvard University say such sleepers are able to block outside noise from getting to their brains and are more likely to manage a night of undisturbed sleep. Researchers studying brainwaves found that the mind produces pulses called “spindles” during sleep that stop noises from getting to the part of the brain that would make the sleeper aware of them. The research showed most people keep a consistent spindle rate and those with higher spindle rates were less likely to be disturbed on noisy nights.
