Sleep deprivation can rob the brain of its opportunity to reorganize and recharge itself. The athletes also showed a boost in mood and a decrease in sleepiness, during both practices and games following a good night’s sleep. One sleep study on basketball players showed a link between increased restful sleep and improved athletic performance. Sleep is also important for increasing our motor skills and enabling us to learn new activities efficiently. This is also when the immune system has time to restore itself, decreasing inflammation and increasing the body’s ability to protect itself. During deeper sleep, hormones are released and regulated, tissues are repaired, muscles are grown, and memory is consolidated. Sleep is when essential bodily processes get to work. The fundamental reason why slow wave sleep is so important is because it allows for restoration. Being woken up mid-REM sleep will likely help you recall a dream, but it’ll leave you feeling tired and sluggish because the cycle wasn’t completed. REM stages tend to lengthen throughout the course of sleep, which is why we often wake up the next day with a vivid dream still clear in our minds. It’s normal to experience five or six cycles of REM sleep per night. REM sleep also speeds up our brain activity and ignites regions of the brain responsible for visual, motor, emotional, and autobiographical processing. Breathing can also become fast, irregular, or shallow (this is the stage where sleep disorders like sleep apnea occur). REM sleep is marked by an increase in eye movement, heart rate, and blood pressure. About 90 minutes after falling asleep and after the first four stages of NREM sleep, the body dips into REM, the second state of sleep. While adults spend more time in NREM sleep than REM sleep, that doesn’t mean REM sleep isn’t important. The third and fourth stages are considered deep sleep, or slow wave sleep (SWS). People in these stages will be harder to wake and will feel more refreshed if they complete the cycle before opening their eyes. Being woken up in this (or any) stage of sleep before it is complete can lead to fatigue, confusion, and lack of rest. These are the stages in which the body slows down and dips into a deep, restorative sleep due to an increase in delta brain waves. Then these waves slow down to induce a deeper rest. The second stage of sleep is a light sleep where the brain waves increase to cause spindles on a sleep chart. In contrast, stage two is the perfect stage of sleep for an energizing power nap. This is the stage of sleep often reached during catnaps, and it doesn’t typically leave a person feeling well-rested. First Stageĭuring the first and lightest stage of sleep, the brain produces alpha and theta waves. According to the National Sleep Foundation, NREM sleep is a dreamless, slow-wave state that includes four main stages of sleep. Controlled by natural variants in brain activity, both of these sleep states are important for helping the body rest and rejuvenate. Sleep is comprised of two main states: REM and non-rem sleep (NREM). What Is Deep Sleep? Understanding Sleep Stages Here’s what everyone needs to know about sleep stages, physical health, and brain function - plus how to increase deep sleep for a healthier tomorrow. If you’re relying on coffee and catnaps to compensate for a lack of deep sleep, a better solution awaits. Not getting enough sleep isn’t just setting you up for tiredness - it’s forging a future of forgetfulness and chronic fatigue. This is because deep sleep is essential for feeling, performing, and thinking at our highest level. When we sleep, we go through several sleep cycles about every 80 to 110 minutes, each of which is made up of four phases.If you’ve ever been roused from a deep sleep, you know just how frustrating (and tiring) it is to wake up before you’re ready. Keep reading to learn about the different stages of sleep, why deep sleep is important and how you can get more of it. Our body and mind work to restore, regenerate and process information during sleep so that we can function optimally in daily life. However, we now know that quality sleep is a complicated, dynamic physiological process that is anything but passive. It was thought that the body and mind became inactive during sleep to rest and recover from the day’s activity. That may sound boring, but this unconscious state is actually much more interesting than previously thought.Īs recently as 70 years ago, researchers assumed the human body went into a dormant state during sleep. It’s estimated that humans spend about a third of our lives sleeping. South Georgia & South Sandwich Islands (GBP £)
