We’ve been told that the secret to good sleep is the magic number:is all you need to be healthy. But that’s not exactly true, since you can sleep for the recommended amount and still not feel rested. That’s because quantity isn’t the only factor that matters — it’s also about the quality of sleep you get.
Getting the right type of sleep can be a complicated topic. We’ll take you through what restful sleep is, why it’s important and how to tell whether you’re getting it.
What is restful sleep?
Our bodies go through four stages of sleep, during which our body temperature changes and our breathing starts to slow. The stages of sleep are divided into two parts: REM sleep and non-REM sleep. Stages one through three are non-REM sleep, and stage four is REM sleep.
Deep sleep, also known as “slow wave sleep,” is the final stage of non-REM sleep. We spend most of our time in deep sleep during the first half of a night. The segments of deep sleep shorten each time we cycle through the sleep stages. Deep sleep accounts for 13% to 23% of nightly sleep.
During deep sleep, your heartbeat and breathing slow down as your muscles relax. Brain waves are also slow during deep sleep. Experts suggest deep sleep is essential for restorative sleep and promotes recovery and growth. Disrupting these cycles impacts the quality of sleep you’re getting — even if you are asleep for eight hours. Not getting enough deep sleep and REM sleep can impact your ability to function.
Signs you aren’t getting restful sleep
Understandably, it’s hard to determine what type of sleep you’re getting… when you’re asleep. However, there are tell-tale behavioral signs that you aren’t getting restful sleep. Here are the most common.
- You wake up and feel exhausted: If you’re not getting enough deep sleep, you’ll feel exhausted, no matter how much you sleep. This is the most common way to tell if your sleep may be the problem.
- You’re irritable: We all have waves of frustration or annoyance. When you’re sleep-deprived, things that wouldn’t usually bother you get under your skin. If you’re unusually quick to anger but seem to be getting more annoyed or annoyed faster than normal, you’re likely not well rested.
- You can’t concentrate on things: When you’re not getting the right kind of sleep, your ability to concentrate and stay alert is lower.
- Your memory is worse: There are several types of memory; our working memory is the temporary information we hold in our mind and use to execute cognitive tasks. Sleep deprivation makes it more difficult to complete these tasks without errors.
- You’re taking more naps than normal: Whether they are planned naps or you drift off while watching TV, if you’re falling asleep out of sequence during the day, you’re not getting enough sleep at night.
