In fact, she notes, the average sleeper moves 40 to 50 times per night. When we’re sleep-deprived, we may move less, but under normal circumstances, she adds, we’re naturally more active during stage 1 or light sleep, as well as REM sleep, than we are in other sleep stages. That said, moving in certain ways can be a sign of a problem. Specific types of sleep movements, such as restless legs syndrome and periodic limb movement disorder1, Stephenson explains, are linked with stress, depression, lifestyle factors like too much caffeine, and even certain health conditions, from diabetes, heart disease, and sleep apnea to ADHD, PTSD, and frequent nightmares. “We know that these sleep disorders, if not the movements themselves, are associated with lower-quality sleep,” Stephenson tells mbg, “but if you feel well-rested during the day, you likely do not have a problem.” Now, if you’re nodding off in the middle of the day or feel you could always use a nap, “that is an indication you might not be getting enough sleep or that your sleep quality is suffering,” she adds. Long story short: If you’re frequently fatigued and struggle with tossing and turning or restless limbs, “There might be a connection, and it might be time to do something about it.” Stephenson recommends ditching the caffeine after noon, or at most 3 p.m., to help you sleep more soundly, adding, “many people find after reducing caffeine intake, they sleep so much better they no longer feel the need for that midafternoon cup of coffee.”
