Do we really need 7-8 hours of sleep, or are there rare exceptions like Napoleon and Edison who could get by with less?

Many people suffer from sleep deprivation and question whether they really need the recommended seven to eight hours of sleep. While some historical figures have gotten by with less sleep, research shows that both too much and too little sleep can be detrimental to your health. Getting the right amount of sleep is an important factor in maintaining good physical and mental health, and sticking to it is essential for long-term well-being.

 

These days, everyone is sleep deprived, including you. According to one researcher’s statistics, the average high school student sleeps about 5 hours and 27 minutes. This is a result of the rapid growth of adolescence combined with academic stress and not getting enough rest. In fact, many of them are experiencing a vicious cycle of accumulated fatigue and stress, which impairs their ability to learn. We grow up hearing that we need roughly seven to eight hours of sleep per night (the FDA’s recommended amount), although this varies by individual. This isn’t just advice, it’s a scientifically validated recommendation for brain development and body repair.
I’m sure there’s some science behind this. However, for me, I’ve found that I can get much less than seven or eight hours of sleep and still be fully functional the next day. Some might argue that while I may be able to get by with a one-time shortage of sleep and still feel fine the next day, the repetition of such a routine will certainly cause health problems. However, people like Napoleon and Edison, among others, lived on three to four hours of sleep a night without any major health problems. Of course, it’s possible that they were mutants who deviated from the general rule of seven to eight hours of sleep.
But what we should pay attention to is whether the examples of some extraordinary people, like Napoleon or Edison, can be applied to the average person. While they may have overcome sleep deprivation in specialized circumstances, it’s likely that most people would struggle to maintain their physical and mental health without adequate sleep. For example, studies have shown that sleep deprivation weakens the immune system and is linked to chronic diseases such as heart disease, diabetes, and obesity in the long run.
Additionally, research on the relationship between sleep and learning shows that sleep is not just rest, but a critical time for strengthening memories and processing information. While you sleep, your brain organizes information from the day and stores important information in long-term memory. If you don’t get enough sleep, these processes don’t work as well, which can negatively affect your ability to learn and think creatively.
Therefore, it seems necessary to investigate whether there is a right amount of sleep, and what the problems and solutions are when we deviate from it. In this article, we’ll try to answer this question based on the current scientific knowledge.
First, we need to discuss whether there is such a thing as an optimal amount of sleep. A statistical study that examines the relationship between sleep duration and mortality can shed some light on this debate. According to a study by a team of world-renowned professors, people who sleep an average of five hours or less per night have a 21% higher mortality rate than those who sleep seven hours. And those who sleep 10 hours or more have a 36% higher mortality rate than those who sleep 7 hours. Based on these statistics, it’s safe to say that too little or too much sleep can be detrimental to your health. That said, there is an optimal amount of sleep, which the FDA considers to be between seven and eight hours.
So, what are the specific problems that occur in the body when you don’t get the recommended amount of sleep? While you sleep, your nervous system is in the process of clearing out the waste products of daytime activity. If this process is disrupted, brain function can decrease and damage the nervous system. It’s also during sleep that a lot of the information we store during the day is organized. Therefore, lack of sleep can lead to problems with concentration and poor memory. For this reason, your ability to work or learn is significantly reduced.
Furthermore, sleep deprivation affects a variety of physiological functions in the body: a weakened immune system makes you more susceptible to diseases, and hormonal imbalances increase the likelihood of developing chronic diseases such as obesity and diabetes. As you can see, getting the right amount of sleep is important for both your body and mind.
On the other hand, too much sleep can also be harmful to your health. According to the March 2013 issue of the American Journal of Epidemiology, the percentage of people in the United States who get nine or more hours of sleep has increased from 28% to 37% in the last 30 years. The researchers found that excessive sleep can increase the risk of heart disease, thinking disorders, and premature death. Excessive sleep can actually slow down brain activity, causing people to stay in bed longer and be less physically active, which can lead to a host of health problems.
These findings highlight the many negative health effects of too little or too much sleep. However, it shouldn’t be overlooked that many people suffer from insomnia, or simply don’t get enough sleep for reasons such as work or school.
Rather than relying on medication, lifestyle changes can be more effective in the long run. Maintaining a regular sleep pattern and avoiding excessive caffeine consumption before bed can help. Stress management is also essential to improving sleep quality.
In the end, it’s important to recognize that sleep is more than just rest in our lives; it’s an important factor that is closely linked to our health. The 21st century is the age of wellness. In order to take care of ourselves and protect our health, we need to remind ourselves of the importance of sleep. Getting seven to eight hours of sleep is the first step to a healthier and happier life.
