What is a coffee nap? How this simple technique can boost your energy and productivity

If coffee makes you sleepy instead of pumping you up, you must know what a coffee nap is.

A coffee nap combines drinking coffee with a short nap. Though it may sound unusual, studies show it can improve alertness and mental sharpness, according to Sleep Foundation.

Timing is key—it’s best done after lunch in the mid-afternoon. The process is straightforward: have your coffee and take a quick nap, no longer than 20 minutes.

Research suggests this method might be more effective for staying awake than either coffee or a nap.

“The idea is that by the time you wake up, the caffeine will have started to kick in, enhancing the nap’s refreshing effects,” said Dr. Markus Ploesser, an integrative medicine physician at Open Mind Health.

How does it work?

Ploesser explained that coffee naps, backed by studies and personal experiences, can enhance alertness and mental function, per HuffPost.

The brief nap clears adenosine, a chemical that causes drowsiness, from the brain. Once the caffeine takes effect, it blocks adenosine, preventing sleepiness and promoting wakefulness.

Once caffeine kicks in, it blocks adenosine, keeping you awake. For caffeine to work well, the brain must clear adenosine first, which is why the nap is important.

A daytime nap, often called a “power nap,” boosts alertness and focus. Studies show the ideal nap is around 20 minutes.

Napping longer than 30 minutes can lead to deeper sleep, which may cause grogginess and disorientation when you wake up.

However, Dr. Keisha Sullivan cautioned that research on coffee naps is still limited. While they work for some people, they may not work for everyone.

She noted that feeling more energetic after a coffee nap means it’s working for you. Still, it’s probably not the right method if you don’t.

Is coffee nap effective?

Coffee naps have proven effective for certain groups, particularly tired drivers and night shift workers.

People can boost their thinking, physical performance, and problem-solving abilities by mixing caffeine with a short nap. Research from the 1990s supports this idea, with several studies showing that caffeine naps work better than just caffeine or napping alone.

In one significant study, participants who consumed 200 milligrams of caffeine and then took a nap before staying awake for 24 hours showed greater alertness, improved reasoning skills, and better test performance than those who only napped.

Researchers are exploring whether caffeine and naps can help drivers stay alert, especially since drowsiness leads to many car accidents.

In one study, participants who consumed 150 milligrams of caffeine or took a short nap felt less tired than those who received a placebo.

The findings showed that drivers who paused for caffeine or a nap experienced better alertness, improved driving performance, and less sleepiness-related brain activity.

Night shift workers can also take advantage of coffee naps. A study found that combining naps with caffeine was the best way to increase alertness and improve performance on tests measuring reaction time, attention, verbal skills, and other cognitive abilities.

Additionally, recent research has examined how caffeine and naps affect athletes, particularly those who lack sleep.

In these studies, researchers compared the effects of a 20-minute nap, moderate caffeine intake, and a combination of both.

The results showed that sleep-deprived athletes who combined caffeine with a nap performed better in sprinting tests than those who only consumed caffeine or napped alone.

When is the best time to take a coffee nap?

The best time for a coffee nap depends on a person’s daily routine. For those who work during the day, mid-afternoon, particularly after lunch, is usually the ideal time to take a coffee nap.

Many people experience a dip in energy after lunch, creating a strong desire to sleep and making it harder to focus on tasks.

Morning coffee naps typically aren’t effective, as there hasn’t been enough adenosine buildup yet. Additionally, napping or drinking coffee too close to bedtime can hurt sleep quality.

Therefore, a quick nap in the early afternoon can be a great way to recharge and improve productivity.

Ploesser recommends drinking your coffee quickly, preferably within 5 to 10 minutes, to maximize the benefits of a coffee nap.

He explains that the aim is for the caffeine to start absorbing while you nap, so its effects hit you right as you wake up.

Sipping your coffee too slowly may delay caffeine absorption, which could lessen the overall benefits of the nap.

Is it safe?

Sullivan states that coffee naps are generally safe for most adults as long as they limit caffeine intake to under 400 mg and about four cups of coffee daily.

However, she recommends that pregnant or breastfeeding individuals and those trying to conceive consult their doctors and aim for less than 200 mg of caffeine daily.

There are no specific U.S. guidelines for teens. Still, she advises them to reduce caffeine consumption, while children under 12 should avoid it entirely.

The professor warns that people with anxiety, insomnia, or heart issues might experience side effects like jitters, heart palpitations, or trouble sleeping.

Additionally, Sullivan notes that certain health conditions or medications might require strict limits on caffeine.

Therefore, she urges anyone considering adding coffee naps to their routine to speak with their doctor first.

Do it with caution

Coffee naps can effectively boost alertness and are generally safe for most individuals. However, Ploesser warns that they should not be used as a substitute for regular, restorative sleep.

He points out that relying too much on coffee naps can hide deeper sleep problems.

To stay healthy, it’s important to prioritize good sleep habits and tackle any sleep disturbances you may have. Quality sleep remains crucial for overall well-being.
