Is 6 Hours of Sleep Enough? Is this Correct or Not?

When it comes to getting enough sleep, we have a tendency to try to cut corners. Getting enough sleep for seven or eight hours may sound like fun, but it rarely seems like we have time. According to the National Sleep Foundation, older adults should get enough sleep for 7-9 hours each night. This recommendation has become quite common among teenagers, and preschoolers. Despite this advice, 45% of Americans say that little or no sleep affects their daily lives at least once a week.

Getting a good night’s sleep is not easy, but it is important. Let’s break down the sheets to learn more about sleep, why just 6 hours of sleep is not enough, and what we can do to make sure we get the shuteye hours we need.

Foundations for Sleep

There are four main categories of sleep that we need to be aware of, and collectively refer to these stages as the sleep cycle.

The first stage is the simplest phase of sleep and is accompanied by slow eye movement or NREM. During this phase of sleep drowsiness, your eyes will move slowly under your eyelids and you can be easily awakened. Your muscles will relax and your brain will begin to slow down as your body prepares for more relaxation and deep sleep.

The second stage of sleep is the first phase of rapid eye sleep (REM). You cannot be easily awakened by this stage of sleep, and your brain will continue to slow down as a result of a brain activity called sleep spindles. Studies show that sleep apnea protects the brain from waking up during sleep.

The third stage of sleep is known as deep NREM sleep. This is a very stimulating sleep phase and is marked by slow-moving waves in the brain. Suddenly waking up at this stage of sleep is rare, and sleep events such as sleep and sleep talking happen during this stage.

The fourth and final stage of sleep is known as REM sleep, and this is where dreams come true. Your eyes will look back and forth, and your brain waves will be more active at this stage of sleep than at two or three stages. If you wake up from REM sleep, there is an increased risk of feeling embarrassed or drowsy the next day.

Ensuring that you reach these four stages of the sleep cycle is very important. One sleep cycle, which will include all four sleep stages, usually lasts about 100-120 minutes and will change with four or five full cycles per night.
