Is 6-Hour Sleep Enough?

It’s important to address a common misconception about sleep. Many people believe that it’s okay to skimp on sleep during the week and make up for it by sleeping more on the weekends. As there are so many things to do on the weekdays sleep seems to be the luxury we barely can get.

But that is untrue. We can suffer tremendously from even one day of insufficient sleep, and our physical and mental health can worsen over several days of insufficient sleep. For this reason, getting at least 6 hours of sleep every night is essential to sustaining optimal energy and well-being.

How Many Hours of Sleep Should I Get Each Day?

Sleep Hours

Adults should strive for 7-8 hours of sleep per night, while children require approximately 9 hours. Getting too little or too much sleep can also contribute to sleep disorders. Studies have indicated that those who sleep between six and nine hours (referred to as the “approximate sleep duration”) are at the lowest risk of suffering a heart attack. The further away one's sleep duration is from this range, the higher the risk of developing health issues.

What If I Sleep Less Than 6 Hours Per Night?

The effect of sleep deprivation on our genes and general health is highlighted by a study from the University of Surrey in the United Kingdom that was published in the Proceedings of the National Academy of Sciences. The discovery that 711 genes linked to metabolism, inflammation, immunological response, and stress might alter in function after only one week of sleep deprivation - less than 6 hours per night - is intriguing.

1.Unstable Mental and Emotional States

The disruption of our biological clock is caused by a lack of sleep, which can lead to unstable mental and emotional states throughout the day. It’s a gentle reminder for all of us to take care of our bodies and ensure we get adequate sleep. It’s a sobering thought to consider the possible long-term harm that persistent disruption of our regular sleep cycles can do to our physiological tissues and organs.

2.Impaired Cognitive Function

Impaired Cognitive Function

Our cognitive abilities are compromised if we lack sleep, which makes it harder to concentrate and pay attention. Decreased productivity, trouble-making judgment, and increased risk of accidents can result from this. Prioritizing ample sleep is crucial for maintaining overall well-being and optimum cognitive function.

3.Higher Susceptibility to Dementia

Because of its effects on our brains, sleep deprivation can make people more susceptible to dementia. It can impair our ability to think clearly, make decisions, and solve problems. These deficits can eventually lead to dementia. Moreover, research has shown that insufficient sleep can increase the production of beta-amyloid, which can further raise the risk of dementia.

4.Increased Risk of Cancer

The International Agency for Research on Cancer(IARC) classified staying up late as a Group 2A carcinogen way back in 2007. Therefore, in order to maintain our health, it’s critical that we make sure we’re receiving enough shut-eye.

5.Chronic Diseases

Including cardiovascular problems, diabetes, obesity, and even a compromised immune system. Prioritizing healthy sleeping practices can help lower the risk of getting various medical issues. Remember to aim for a solid 7-9 hours of sleep each night to support your overall well-being.


All in all, it is totally understandable that some people may feel OK with just six hours of sleep, but it’s crucial to recognize that this may not be enough for the majority of people. Research has repeatedly demonstrated that obtaining 7-9 hours of sleep is quite important. Constantly falling short of the prescribed sleep duration can have detrimental impacts on your overall health, mood, and cognitive function. Thus, it’s imperative that you prioritize sleep and make the necessary adjustments to guarantee that you get enough sleep every night.
