Sleep is vital for the brain and body to function at their best, but it is possible to train yourself to need less sleep. Sleep expert Jim Horne says that the number of hours people need to sleep is flexible from person to person and that concerns about not getting enough sleep are often overblown. Horne's 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. However, when a person doesn't get enough sleep, their brain can't repair or build new pathways, making it more difficult to retain information, engage in complex thinking and stay focused. Sleep deficiency has also been linked to physical health problems, such as obesity, high blood pressure and heart disease.

You can't train yourself to need less sleep, but you can optimise your sleep habits and routine
Sleep is vital for the brain and the body to function at their best. When a person doesn't get enough sleep, their brain can't repair or build new pathways, making it more difficult to retain information, engage in complex thinking and stay focused. Sleep deficiency has also been linked to physical health problems, such as obesity, high blood pressure and heart disease.
However, according to sleep expert Jim Horne, the number of hours people need to sleep is more flexible from person to person and concerns about not getting your nightly seven or eight hours are often overblown. Horne's 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. Horne suggests focusing on getting quality sleep rather than worrying about the quantity. Making better use of your waking hours is another way to thrive on less sleep. Try exercising in the afternoon, says Sigrid Veasey, a professor at the Center for Sleep and Circadian Neurobiology at the University of Pennsylvania’s Perelman School of Medicine.
You can't change your genes and become a short sleeper, but you can optimise your sleep habits and routine. This isn't quite the same thing as training your body to need less sleep, but it is an effective way to make the most out of the sleep you get. It will also help you zero in on the exact amount of sleep you need in order to feel your best.
Tips for optimising your sleep include avoiding a large meal late in the evening, making time to think about worries before bed so you don't go to sleep stressed, avoiding looking at screens right before you sleep, and raising your body temperature and then cooling it down by bedtime, which will help you fall asleep more quickly and sleep more deeply through the night.

Sleep is vital for the brain and body to function at their best
While it may be possible to train yourself to get by on less sleep, sleep expert Jim Horne says that concerns about not getting seven or eight hours a night are often overblown. Horne's 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. However, Horne says that if you feel sleepy during the day, six hours is probably not enough for you. Instead, he recommends focusing on getting quality sleep rather than worrying about the quantity.
You can also make better use of your waking hours by exercising in the afternoon, for example. Other tips for optimising your sleep include avoiding a large meal late in the evening, making time to think about worries before bed so you don't go to sleep stressed, and avoiding looking at screens right before you sleep.
