The Surprising Reason Why a Weekend Lie-In Won't Cure Your Weekday Exhaustion
Sleep expert Professor Russell Foster explains that catching up on sleep over the weekend is unlikely to compensate for sleep debt accumulated during the week. Oversleeping on weekends can throw off the body's internal clock, making it harder to fall asleep at night. Those who regularly feel tired, irritable, and in need of sugary or caffeinated drinks may need more time in bed. However, sleeping in at the weekend can have a negative impact on the body clock if it prevents exposure to morning light. Foster suggests going to bed earlier in the evening and sticking to a regular routine to improve sleep.
