Coffee Nap: Does It Really Work?

Coffee Nap: Does It Really Work?

When your energy levels drop in the middle of a long day, the word nap or coffee comes to mind, one or the other - but never together. The two words seem like an odd match and are even counterintuitive, as coffee is a stimulant that fights sleep. However, a ‘coffee nap’ works better than just a nap or coffee alone.

But First, What Is A Coffee Nap?

A coffee nap is having a cup of coffee a short period before a nap, usually 20 minutes before it. Also known as a caffeine nap, this method is believed to help you reap the benefits of both a nap and coffee. When you wake up from your coffee nap, you should be feeling refreshed and energized.

How Does A Coffee Nap Affect You?

As the day progresses, adenosine, a chemical that promotes sleep, slows down nerve cell activity in the brain and causes drowsiness. When you drink coffee, the caffeine is absorbed by your small intestines and goes into your bloodstream, eventually, it gets to the blood-brain barrier and reaches your brain.

With a coffee nap, once you fall asleep, your adenosine level goes down. This makes your brain receptors available so when the caffeine reaches your brain, it’ll trick the brain’s adenosine receptors and easily bind to them. By taking over the adenosine receptors, it decreases the adenosine effect. The nerve cells start to speed up again as caffeine blocks adenosine from its receptors and coffee does its magic!

As a result, sleep helps the caffeine get rid of adenosine, the feeling of drowsiness, and your energy levels are boosted. Coffee and napping work better together than just coffee or a nap alone.

Research On Coffee Naps: Does It Really Work?

Research On Coffee Naps: Does It Really Work? | Puffy

Researchers and scientists conducted a few studies on coffee naps and the results were promising. All of the studies indicated that coffee naps were effective, even more so than just drinking coffee or taking a nap alone.

One study was done on 12 sleepy individuals who each took 12 mg of caffeine (equivalent to two cups of coffee) followed by a 15-minute nap. Then they were placed in a driving simulator for two hours. 91 % felt less sleepy while driving, compared to the control group who only had coffee. Even those that were half asleep or just resting, showed a significant improvement in their energy levels.

Another study conducted on 10 healthy young adults indicated that taking 200 mg of caffeine followed by a short nap was the most effective in fighting against mid-afternoon sleepiness and performance level of computer tasks. Other methods included a nap then exposure to bright light, a nap then face washing, and no nap at all.

The results of these studies imply that combining caffeine and sleep increases alertness, boosts productivity, and recharges energy levels.

Duration & Timing of a Coffee Nap

The duration of a coffee nap is vital to preserving a healthy sleep cycle. Experts suggest that a nap should range from 15 minutes to a maximum of 30 minutes, the optimal nap would be 20 minutes long.

If your nap is longer than that, it’ll affect your sleep quality at night and it will also ruin any good coming from a coffee nap. It takes around 20 minutes for the caffeine to reach your brain and start affecting your body. If you sleep for longer than that, you will reach the deep sleep phase but your sleep will be disrupted and you’ll wake up feeling tired and irritated.

Waking up abruptly from deeper stages can lead to sleep inertia. This is to feel lethargic and groggy for some time after waking up. A short nap of 30 minutes or less can prevent this from happening because you’ll wake up before getting deep sleep.

As for the timing of a coffee nap, you can have it anytime during the day, as long as it is at least 6 hours before your bedtime. A coffee nap can disrupt your sleep at night because caffeine can have adverse effects that last for a long time. These effects include palpitations, faster heartbeats, and a rise in blood pressure. It’s best to try and schedule it mid-day, in the afternoon, or the morning, if you feel lethargic after you wake up.

It’s important to note that the amount of coffee you drink can affect the effectiveness of your coffee nap. Experts recommend 200 mg of caffeine for a coffee nap, suggesting that this is the proper amount to have you feeling refreshed and energized when you wake up.

If you don’t drink coffee, you can drink soda, energy drinks, or tea - but you need to ensure they have the same amount of caffeine you’d get from a black coffee. However, they may contain other components, like sugar, that can get in the way of having an effective coffee nap.

Additionally, it’s best to have your coffee in its unadulterated black form. This means drinking it without adding sugar, milk, cream, or artificial flavors. External components will get in the way of the caffeine’s effect and will slow down the process.

As a result, the best option is to have an espresso or black coffee. Lastly, slowly sipping your coffee will ruin your coffee nap. Caffeine takes approximately 20 minutes to reach your brain. If you’re slowly drinking coffee, your energy levels will go up before you’ve gotten the chance to nap.

Consider drinking cold coffee or cooling it down beforehand so that you can drink it quickly. Once done, just lie down, close your eyes, and relax. You don’t need to be completely asleep for a coffee nap to work, it’ll be effective even if you’re just half asleep.


How long should a coffee nap be?

A coffee nap should be from 15 to 30 minutes, the ideal nap should be 20 minutes long. If your nap is longer, this will ruin the effect of a coffee nap as well as disrupt your sleep quality at night. Caffeine takes approximately 20 minutes to reach the brain and start impacting your energy levels so a short nap will help you to wake up feeling energized and productive.

Are caffeine naps real?

If done the right way, a caffeine nap can make a huge difference in your performance level and overall productivity. The effectiveness of a caffeine nap depends on the amount of coffee consumed and the duration of your nap. In order to reap the maximum benefits of a caffeine nap, your coffee should include 200 mg of caffeine and your nap should be from 15 to 30 minutes.

Can you sleep after drinking coffee?

Caffeine takes an average of 20 minutes to get through your bloodstream, reach your brain, and start affecting your body. As a result, you can achieve light sleep if you take a nap immediately after drinking coffee. But if you drink coffee before sleeping at night, it will disrupt your sleep.

What’s the best time for a coffee nap?

You can have a coffee nap whenever you need it during the day. It can be mid-day when you feel like you’re losing concentration or in the morning if you feel groggy after you wake up. Most importantly, it is recommended to have a coffee nap at least 6 hours before your bedtime so that it doesn’t affect your sleep at night.

Is it better to nap or have coffee?

When you’re feeling tired or unproductive mid-day, both options feel right. A quick nap or a cup of coffee can both help you feel refreshed, but a coffee nap will do the job even better. Consider drinking unadulterated coffee and then taking a nap for 20 minutes for maximum effectiveness.

Is it bad to sleep after drinking caffeine?

Caffeine will make it hard to fall asleep and if you do, it can be disruptive to your sleep and will affect your sleep quality. It is best to only drink coffee at least 6 hours before your bedtime to avoid symptoms like restlessness, headaches, faster heartbeats, and insomnia.

Should You Take Coffee Naps?

If you’re a fan of coffee, then this method is worth trying out. Coffee naps are a great way to boost your energy levels during the day. However, if you drink a lot of coffee, you’ll need to control the amount of caffeine you consume per day. Experts recommend a maximum of 400 mg of caffeine, which is equivalent to 4 cups of coffee, per day.

Excessive coffee can cause stomach cramps, digestion problems, restlessness, faster heartbeats, and even anxiety, so you should be careful with your coffee consumption. For a coffee nap to be effective, you’ll need to dedicate approximately 200 mg of caffeine. But if you don’t normally drink coffee or if you have a sensitive stomach, maybe try something lighter like green tea.

Finally, remember to have a coffee nap at least 6 hours before bedtime to get the best results of your nap and still achieve deep sleep at night.
