In this study, the researchers instructed 95 people, who normally slept around 7.5 hours a night, to go to bed 1.5 hours later than usual for six weeks, while getting up at the same time. They wore wrist monitors and had their blood hormone levels tested, among other measures, to assess any changes happening over the course of the study.\u00a0<\/p>\n<\/div>\n<div>\n<p data-testid=\"paragraph-element\" class=\"rich-text mb-6 font-graphik text-body-large text-black-coffee focus-visible:outline focus-visible:outline-black-coffee focus-visible:outline-2 focus-visible:outline-offset-2 focus-visible:shadow-focus-color text-left\">The sleep-deprived participants gained about a pound over the six-week period, and their levels of leptin, a hormone linked to body fat, went up. \u201cWe found that they spent more time being sedentary during this period of sleep restriction compared to the period of adequate sleep,\u201d says St-Onge. They were awake for longer, but they were less apt to use that time for exercise or moving around.<\/p>\n<\/div>\n<p><h2 id=\"can-the-effects-of-sleep-deprivation-be-reversed\" class=\"scroll-mt-24 font-editorial text-black-coffee text-mobile-h2 lg:scroll-mt-28 lg:text-h2 mb-4\">Can the effects of sleep deprivation be reversed?<\/h2>\n<\/p>\n<div>\n<p data-testid=\"paragraph-element\" class=\"rich-text mb-6 font-graphik text-body-large text-black-coffee focus-visible:outline focus-visible:outline-black-coffee focus-visible:outline-2 focus-visible:outline-offset-2 focus-visible:shadow-focus-color text-left\">The results mesh well with what was already known about sleep and body weight from more extreme experimental studies, says Dr. Sirimon Reutrakul, an endocrinologist and professor of medicine at the University of Illinois College of Medicine who was not involved in the study.\u00a0<\/p>\n<\/div>\n<\/div>\n<script async=\"async\" data-cfasync=\"false\" src=\"https:\/\/pl30214220.effectivecpmnetwork.com\/9ab3d4df8a7e1a6171e16ddbf732cc19\/invoke.js\"><\/script>\r\n<div id=\"container-9ab3d4df8a7e1a6171e16ddbf732cc19\"><\/div>\r\n\n","protected":false},"excerpt":{"rendered":"<p>The optimum amount of sleep varies by individual, but most people need between seven and nine hours a night.
