Sleeping a full eight hours doesn't guarantee you'll wake up feeling rested. In the first episode of Kensington Furniture's Sleep Well Series, host Dan explains that being tired usually has less to do with how many hours you spent in bed and more to do with how you slept during those hours.Why am I still tired after 8 hours of sleep?You're likely tired not because you slept too little, but because you didn't spend enough time in deep sleep. As Dan puts it in the video, "You're not tired because you didn't sleep enough hours. You're likely tired because of how you slept, then." Total time asleep matters less than which stages of sleep you actually reach.What deep sleep does for your bodyDan explains that the brain has a lymphatic system that only turns on during sleep. During waking hours, toxic proteins build up in the brain, and this system is responsible for flushing them out. Of the four stages of sleep, Dan identifies deep sleep as the one where this cleanup process activates, and he calls it arguably the most important stage for bodily recovery.What can keep you out of deep sleepSeveral common habits can prevent your body from reaching deep sleep, according to the video: Alcohol Nicotine Chronic stress Irregular bedtimes Any one of these, on its own or combined, can interfere with your body's ability to settle into the deep sleep stage where the lymphatic cleanup happens.A simple fix: a consistent bedtimeDan points to a straightforward strategy backed by sleep experts: go to bed at the same time every night. Doing so helps regulate your circadian rhythm, the internal clock that governs when your body is primed for sleep. Rather than chasing a specific number of hours, the goal is consistency, night after night, so your body knows when to wind down and when it's time to do its deepest work.About the Sleep Well SeriesDan works at Kensington Furniture Mattress in Northfield, New Jersey, and created Sleep Well as a video series drawing on his journalism background to look at aspects of sleep that don't usually get discussed. Each episode covers something different, with the aim of getting viewers to think differently about their nights.
