Have you ever stayed up late studying for an important exam, only to find yourself struggling to focus the next day? You’re not alone! Many people experience this, and it turns out that lack of sleep can affect your brain in ways similar to alcohol consumption.
A study conducted in 2000 by researchers from Australia and New Zealand explored how sleep deprivation impacts cognitive abilities. They kept volunteers awake for up to 28 hours and tested their performance on various tasks. On a different occasion, the same participants were tested after consuming alcohol to reach different blood alcohol levels. The results were surprising: after 17 to 19 hours without sleep, participants performed similarly to those with a blood alcohol level of 0.05. Some even showed impairments comparable to a level of 0.1, which is above the legal driving limit in the United States.
Another study from 2000 at UC San Diego used fMRIs to examine the brains of sleep-deprived individuals while they performed verbal learning tasks. The researchers found that the prefrontal cortex, which is responsible for planning and decision-making, was working overtime in sleep-deprived individuals. This means the brain was putting in extra effort to complete the same tasks. Meanwhile, the temporal lobe, which helps with hearing, speech, and memory, was less active.
When you’re sleepy, you might notice your speech becomes slurred, similar to being intoxicated. This is because the temporal lobe isn’t as active. To make up for this, the parietal lobe steps in, but it doesn’t perform as well for these specific tasks, leading to less efficiency.
Sleep is crucial for your brain’s health. It allows neurons to rest and regain sensitivity by regulating neurotransmitters like serotonin and dopamine, which help brain cells communicate. Without enough sleep, these neurons can become less sensitive, slowing down brain function.
Staying up late can significantly impact your cognitive abilities, much like drinking alcohol. This is a serious concern, as many drivers fall asleep at the wheel every day. If you plan to stay up late, make sure you have a safe way to get home.

Imagine you’re a scientist conducting a study on sleep deprivation. Create a simulation where you compare the effects of sleep deprivation and alcohol on cognitive tasks. Use online tools or apps to simulate these conditions and record your observations. Discuss your findings with your classmates.
In groups, role-play different parts of the brain affected by sleep deprivation: the prefrontal cortex, temporal lobe, and parietal lobe. Act out how these parts function normally and how they change when sleep-deprived. Present your skit to the class and explain the science behind your performance.
Keep a sleep diary for one week. Record your sleep patterns, how you feel each day, and your ability to focus in class. At the end of the week, analyze your data and write a short reflection on how sleep affects your daily life and school performance.
Create an interactive map of the brain using digital tools. Highlight the areas affected by sleep deprivation and describe their functions. Share your map with the class and explain how sleep impacts each part of the brain.
Participate in a class debate on the topic: “Is it better to stay up late studying or to get a good night’s sleep before an exam?” Use evidence from the article and other research to support your arguments. Reflect on the debate and consider how it might change your study habits.
Sure! Here’s a sanitized version of the transcript:

Where are my car keys? Hey everyone, Jules here for DNews! We’ve all been there. You stay up late studying because you forgot you had an important final exam the next morning. After just a short amount of sleep, you wander around in a daze, struggling to focus. Unfortunately, you might not do well on that exam.
In fact, being sleep deprived can impair your abilities similarly to being under the influence of alcohol. A study from 2000 conducted by researchers from Australia and New Zealand kept a group of volunteers awake for up to 28 hours and then tested them on various cognitive tasks. On another occasion, the same participants were tested after consuming alcohol to reach different blood alcohol levels. The researchers found that after about 17 to 19 hours without sleep, participants performed similarly to those with a blood alcohol level of 0.05, and some even showed impairment comparable to a level of 0.1, which is above the legal limit for driving in the United States.
So, what happens in your brain when you’re sleep deprived? Another study from 2000 at UC San Diego used fMRIs to examine the brains of sleep-deprived individuals while they performed verbal learning tasks. They discovered that the prefrontal cortex, responsible for planning and decision-making, was overly active in sleep-deprived individuals, indicating that the brain was working harder to perform the same tasks. In contrast, the temporal lobe, which is involved in hearing, speech, and memory, was less active in sleep-deprived subjects.
Sleepy individuals often have slurred speech, similar to those who are intoxicated, and this is related to the activity in the temporal lobe. To compensate for this lack of activity, the parietal lobe becomes more active, but it doesn’t perform as effectively as the temporal lobe for specific tasks. This explains why tasks can still be completed, but with much less efficiency.
Sleep allows your brain’s neurons to rest and regain sensitivity by regulating neurotransmitters. These neurotransmitters, such as serotonin and dopamine, help in communication between brain cells. When you don’t get enough sleep, your neurons can become less sensitive, which may slow down brain function.
In summary, staying up late can significantly affect your cognitive abilities, much like alcohol consumption. This is concerning, as studies indicate that a substantial number of drivers fall asleep at the wheel every day. So, if you plan to stay up late, consider arranging for a safe way to get home.

Sleep – A natural state of rest for the body and mind, during which consciousness is suspended and the body can recover and repair itself. – Getting enough sleep is crucial for maintaining good mental health and cognitive function.
Deprivation – The lack or denial of something considered to be a necessity, such as sleep, which can negatively affect health and well-being. – Sleep deprivation can lead to problems with concentration and mood swings.
Brain – The organ in the head that controls thoughts, memory, emotions, and the nervous system. – The brain requires adequate rest to process information and store memories effectively.
Cognitive – Relating to mental processes such as thinking, learning, and remembering. – Regular exercise has been shown to improve cognitive abilities in teenagers.
Alcohol – A chemical substance that can alter mood and behavior, often affecting the brain and cognitive functions. – Consuming alcohol can impair judgment and slow down reaction times.
Neurons – Specialized cells in the brain and nervous system that transmit information through electrical and chemical signals. – Neurons communicate with each other to help us think, feel, and move.
Health – The overall condition of a person’s body or mind, particularly in terms of the presence or absence of illness or injury. – Maintaining a balanced diet and regular exercise is essential for good health.
Memory – The ability to store, retain, and recall information and experiences in the brain. – Studying regularly can help improve memory and academic performance.
