“You can’t always fully ‘pay back’ lost sleep simply by sleeping extra hours on weekends or days off,” he said, adding that adults should aim for about seven hours of sleep each night.
He said going to bed and waking up at the same time every day, including on weekends, is crucial.
“This regularity helps regulate the body’s internal clock, improving both sleep quality and daytime functioning,” the consultant ENT surgeon and medical director said.
Dr Kuljit added that the effects of a single night of poor sleep can often be reversed by returning to a healthy sleep routine over the following days.
However, persistent sleep deprivation over several days or even weeks can have serious consequences for both physical and mental health, he said.
