Hey there! I’m Craig, and today we’re diving into a big question: Can you actually feel tired from sleeping too much? It sounds strange, right? How can you feel exhausted after sleeping for 11 hours? Let’s explore if this is really possible.
Surprisingly, the answer is yes, you can feel tired from oversleeping. When people sleep for a long time, they often feel more sluggish and less motivated. This groggy feeling even has a name: sleep drunkenness.
Inside your brain, there’s a part called the hypothalamus, which has something known as the circadian pacemaker. This acts like a body clock, helping you know when to sleep and wake up. It follows a 24-hour cycle influenced by light. If you usually wake up at a certain time and then sleep longer, it can mess up this cycle, making you feel like you have jet lag.
Feeling groggy isn’t the only issue. There are more serious health risks linked to sleeping too much. A study from Finland in 2007 found that people who regularly sleep more than eight hours have a 20% higher risk of dying earlier. According to Harvard Health Publications, sleeping more than 10 hours regularly can increase the risk of heart disease, stroke, type 2 diabetes, and depression. If you find yourself oversleeping often, it might be a sign of a health problem like sleep apnea or narcolepsy, so it’s a good idea to talk to a doctor.
You might be wondering how much sleep is just right. The amount of sleep you need can vary based on your age, lifestyle, and health. If you’re over 18, you probably need between 7 and 9 hours of sleep. If you’re between 11 and 17 years old, aim for about 8.5 to 9.5 hours each night.

Track your sleep for a week using a sleep app or a journal. Record the hours you sleep and how you feel each morning. At the end of the week, analyze your data to see if there’s a pattern between the amount of sleep and how rested you feel. Share your findings with the class.
In groups, create a short skit that explains how the hypothalamus and circadian rhythm work. Use props or costumes to make it fun and engaging. Perform your skit for the class and discuss how disrupting this cycle can affect your energy levels.
Choose one health risk associated with oversleeping, such as heart disease or diabetes. Research how oversleeping contributes to this condition and present your findings in a poster or slideshow. Include tips on how to maintain a healthy sleep schedule.
Participate in a class debate about the ideal amount of sleep for teenagers. Use evidence from scientific studies to support your arguments. Discuss how individual differences might affect sleep needs and what factors can influence these needs.
Write a short story or diary entry from the perspective of a teenager experiencing sleep drunkenness. Describe their day and how oversleeping affects their mood, energy, and activities. Share your story with the class and discuss ways to improve sleep habits.
Sure! Here’s a sanitized version of the transcript:

Hi, I’m Craig, and this is Mental Floss on YouTube. Today, I’m going to answer Sara F’s big question: Can you really be tired from sleeping too much? This is definitely something you hear people say all the time, but it doesn’t make much sense. How can you be so tired if you just slept for 11 hours? Well, let’s find out if it’s true.
So, the short answer is yes, you can be tired from sleeping too much. After sleeping for a long time, people tend to report an increase in lethargy and a decrease in motivation. In fact, the groggy state that results from sleeping too much has a name: sleep drunkenness.
In your brain’s hypothalamus, there’s something known as the circadian pacemaker. This regulates when you fall asleep and when you wake up. It works based on our 24-hour days and is affected by the light coming in through our eyes, creating a cycle. If that cycle is accustomed to you waking up at a certain time, it can be disturbed when you sleep for a few hours past that time, making you feel like you do when you have jet lag.
There are more serious risks than just feeling groggy. For example, a study conducted in Finland in 2007 determined that the risk of mortality increases by 20% in people who consistently sleep for longer than eight hours. According to Harvard Health Publications, people who regularly sleep for longer than 10 hours have a greater risk of heart disease, stroke, type 2 diabetes, and depression. If you’re oversleeping on a regular basis, it may be a sign of another issue, like sleep apnea or narcolepsy, so see your doctor if that’s the case.
Now, you might be wondering how much sleep you actually need. Well, the amount is different for every person and depends on factors like age, lifestyle, and health. If you’re over 18 years old, you probably need between 7 and 9 hours. If you’re between 11 and 17 years old, you’ll need around 8.5 to 9.5 hours.
