Is 6 Hours of Sleep Enough? Here’s the Ultimate Guide

Sleep is an integral aspect of life and you may be surprised to learn how greatly it affects your cognitive abilities and body performance in general. The topic of sleep and how much each one of us requires has gained various insights from different bodies and individuals. Of all that has been said about sleep, you would agree with me that 6 hours is the most controversial modern sleeping time.

While many of us feel like we are getting enough sleep, studies have depicted that sleep time is continually reducing in the modern world. So, considering the benefits sleep has to our wellbeing, how do we know that we are getting enough sleep? Is 6 hours of sleep enough for every person? Is sleep time even a constant factor for all people? Let’s shed some light on these questions.

Is 6 Hours of Sleep Enough

A quick answer of Is 6 Hours of Sleep Enough

Despite 6 hours being an okay sleep time in the modern world, it is not enough regardless of the age group. First, I must begin by saying that sleep time varies from person to person according to their specific needs and some underlying factors such as work schedules. However, in general, our bodies still need an additional one to two hours to the popular 6 hours of sleep time, considering the complex tasks we involve ourselves in each day.

Now let’s jump into the ultimate guide that will clear the air on the topic of how much sleep we should get with our reference time being 6 hours.

An overview of the sleep cycle

Is 6 Hours of Sleep Enough

Have you ever thought of how the numbers we consult to know the average sleep time we need are arrived at? They all stem from the human sleep cycle. Generally, to get enough sleep, you must go through at least four sleep cycles, each lasting about 90 minutes and with the following stages:

Stage 1- Drowsy sleep

This is the sleep preparation stage you go into when you get to bed. Here, there is non- rapid eye movement beneath the eyelid and hence you can easily be woken by any sleep disturbances. The activities of your brain slow down as you move to a more restful sleep stage.

Stage 2- Spindles sleep

As your brain relaxes, it moves to a series of activities that protect it from awakening called sleep spindles. There is rapid eye movement during this stage of sleep, and you can’t easily be woken up.

Stage 3- Restorative sleep

Each time you sleeptalk or sleepwalk, you are most likely in the restorative sleep stage. If you come to think of it, you can only sleepwalk if you are in a very deep sleep state. In this sleep stage, the activities of the brain are significantly reduced. Although this is a non-rapid eye movement sleep stage, you can’t, again, be easily woken.

Stage 4- Active sleep

This is a rapid eye movement sleep stage characterized by a rise in brain activities. In this last stage, you are likely to have a dream and if you wake up when your dream is at its maximum, you probably got enough sleep.

As seen above, sleep is a complex process that must involve all of the above stages. The time you take to complete each stage may vary from person to person or from a sleeping cycle to another. If we consider a minimum of 4 sleep cycles, each taking at least 90 minutes, you need a minimum of 6 hours to complete a perfect sleep and rest period. However, it would help if you had an extra hour or two to cater to the transitioning time from one stage to another and compensate for stages and cycles that delay.

Why 6 hours of sleep is not enough?

Most of the studies done to determine enough sleep time for an average person have shown that 6 hours is insufficient. A sleep study published in a journal called ‘sleep’ showed clearly this aspect. The study subjected some individuals to different hours of sleep and then evaluated their performance and overall experiences. Surprisingly, the study’s findings on the people subjected to 6 hours of sleep time showed that their cognitive performance was similar to people who did not sleep at all.

While in such a study, the subjects can explain their experiences honestly after different hours of sleep, we usually tend to assume that we have got enough sleep each time we wake up to handle a task. It is okay to sleep for 6 hours as even in most of the studies, subjects are able to hold up quite nicely for at least a week. However, if you sleep for 6 hours a day for more than ten days, your cognitive performance will be significantly affected and you will always be in a sleep debt-like situation.

Even if we borrow some numbers from leading organizations such as the national sleep foundation, we still see 7-8 hours being the recommended sleeping time for older adults. Therefore, it would not hurt if you sleep for an additional hour to the 6 hours you are accustomed to.
