Ever feel sleepy, tired, or just plain unmotivated in the afternoon? Many of us reach for coffee, soda, or energy drinks to get through the day, yawning and fighting off fatigue. But what if the real solution is something we’ve been avoiding: sleep?
Napping might actually be one of the best ways to refresh your brain. When you sleep, your body goes through four main stages. The first two stages are light sleep, the third is deep sleep, and the last stage is called rapid eye movement (REM) sleep, where most of your dreaming happens.
The benefits of napping depend on how long you sleep. A nap of about 30 minutes usually lets you enter only the first stages of sleep. In stage 1, your eyes move slowly, and if you wake up, it might feel like you didn’t sleep at all. In stage 2, your brain starts to ignore things around you that aren’t important, helping you relax. This stage is also where your brain processes and stores information, making it great for memory.
Waking up from these stages can make you more productive, improve your thinking, boost your memory, spark creativity, and most importantly, make you feel less tired. If you nap for more than 30 minutes, you might enter stage 3, which is deep sleep. Waking up from this stage can make you feel groggy and slow because your body is coming out of a deep sleep.
Some people think naps don’t help them, but they might just be napping for too long. As more people understand the benefits of napping, places like nap salons have popped up in Japan. These salons let workers pay to take a short nap during lunch, helping them feel more alert at work.
So maybe it’s time we all start embracing naps a little more. Just tell your boss, “Science said so.”

Conduct a personal experiment by taking a 20-30 minute nap after school for a week. Record how you feel before and after the nap each day. At the end of the week, analyze your findings and share your results with the class. Did napping improve your mood, energy, or productivity?
In groups, create a short skit that demonstrates the four stages of sleep. Assign each member a role representing a different stage. Perform your skit for the class, explaining what happens in each stage and why it’s important for a refreshing nap.
Imagine you are tasked with designing a nap-friendly area in your school or workplace. Create a blueprint or model of your design, considering factors like comfort, noise reduction, and privacy. Present your design to the class and explain how it would help improve productivity and well-being.
Participate in a class debate on the topic “Should naps be allowed in schools and workplaces?” Research arguments for and against napping, and prepare to defend your position. Use evidence from the article and other sources to support your arguments.
Work in pairs to create a campaign promoting the benefits of napping. Design posters, social media posts, or a short video to educate others about the positive effects of napping and how to nap effectively. Share your campaign with the class and discuss its potential impact.
**Sanitized Transcript:**
Feeling groggy, tired, or unmotivated in the afternoon? Using coffee, soda, and energy drinks, we often try to push through the long day, yawning through the hours and fighting fatigue. But it turns out that the solution is the very thing we’ve been trying to avoid all along: sleep.
The truth is, napping might be one of the most effective ways to rejuvenate your brain. There are four main stages of your sleep cycle. The first two stages are relatively light sleep, while the third brings you into a deep slumber. The final stage, known as rapid eye movement (REM), is where most of your dreams occur.
The benefits of napping are tied to the length of time you sleep. Naps of about 30 minutes generally allow you to enter only the first stages of sleep. In stage 1, slow eye movement begins, and if you are woken, you often feel as though you didn’t even sleep. As you continue into stage 2, your brain begins to inhibit processing and ignores external stimuli that it deems non-dangerous, allowing you to relax and enjoy a tranquil sleep. This stage also involves memory consolidation, where information you learn is processed.
Waking from these stages has shown benefits including increased productivity, enhanced cognitive function, improved memory, boosted creativity, and, most importantly, feeling less tired. Beyond 30 minutes, you enter stage 3 and may experience something known as sleep inertia when awakened. Because your body is coming out of a deep sleep, motor dexterity may decrease, and feelings of grogginess and the desire to return to sleep can increase.
Many people mistakenly believe naps are non-beneficial for them, but the truth is, they may have simply napped for too long. As the benefits of napping become clearer, many nap salons have opened throughout Japan, where workers can pay to take a brief lunchtime nap on a daybed to increase alertness at work.
So maybe it’s time we all start embracing naps a little more. Just tell your boss, “Science said so.”
