How many hours of sleep do you get each night? Always tired? Sleep like a baby? The science of sleep is big business and generates a lot of health and science news these days.  President Donald Trump is said to get anywhere from an hour and a half to four hours a night.  That’s not a lot and it certainly goes against much of the medical recommendations for best health and mental function - but sleeping less has its appeal in that it would allow you to get an awful lot done.

Health issues aside, some in science says you may be able to train yourself to need less sleep. Experts from a Sleep Research Center in England say the number of hours people need to sleep varies from person to person and that concerns about not getting your nightly seven or eight hours are often overblown.

Research shows that people can cut down their regular sleep to about six hours a night, plus a short nap during the day, as long as they do it gradually.
