We have all observed that people look better after a full night of sleep. Now a research team has measured this scientifically. At BBC News: Beauty sleep concept is not a myth, says study.
The idea of people needing “beauty sleep” has acquired some scientific backing, according to a Swedish study. . . .
The authors wrote in their paper published in the British Medical Journal: “Sleep deprived people are perceived as less attractive, less healthy and more tired compared with when they are well rested.”
People under time pressure often imagine they can create more time for themselves by staying up late or getting up early. This may work to a slight extent or to get through a crisis situation, but when people try to do it as a lifestyle, the costs of a shorter night quickly overwhelm the gains of a longer day. From Fear of Nothing:
Moderate sleep deficit is known to cause irritability, diminished alertness, bad test scores, weight gain, and accidents. Increasing levels of sleep deprivation lead to impaired judgement, emotional instability, paranoid thoughts, hallucinations, and falling asleep involuntarily.
And sleep loss isn’t pretty, either. When it seems as if you always have too much to do, the right approach is not to cut back on sleep, but on the to-do list.
