Nap And Coffee: Drinking coffee before a nap may seem counterintuitive. However, many people endorse this habit as a way to boost energy levels. This article provides a detailed look at the science behind coffee naps and whether they offer benefits.
What Is a Coffee Nap?
Nap And Coffee, A coffee nap refers to drinking coffee before sleeping for a short period of time.
This is thought to boost energy levels because of its effect on adenosine, a chemical that promotes sleep.
Nap And Coffee, When you feel tired, adenosine circulates through your body in high amounts. After you fall asleep, adenosine levels begin to drop.
Caffeine competes with adenosine for receptors in your brain. So while caffeine doesn’t decrease adenosine in your body as sleep does, it prevents this substance from being received by your brain. Therefore, you feel less drowsy.
Nap And Coffee, Scientists suspect that drinking coffee before a nap may boost energy levels, as sleep helps your body get rid of adenosine. In turn, caffeine has to compete with less adenosine for the receptors in your brain.
In other words, sleep may enhance the effects of coffee by increasing the availability of receptors for caffeine in your brain. That’s why a coffee nap may increase energy levels more than just drinking coffee or sleeping.
Nap And Coffee, You may think that drinking coffee would prevent you from napping, but keep in mind that it takes some time until your body feels the effects of caffeine.
Nap And Coffee: Timing Your Coffee Intake and Naps
Nap And Coffee, Most experts propose that the best way to take a coffee nap is to consume caffeine right before falling asleep for approximately 15–20 minutes.
This timing is suggested partially because it takes about that long to feel the effects of caffeine.
Nap And Coffee, Moreover, you may fall into a type of deep sleep called slow-wave sleep if you sleep for a half-hour or more.
Waking up during slow-wave sleep can lead to sleep inertia, a state of drowsiness and disorientation. It’s thought that limiting coffee naps to less than 30 minutes may prevent this.
Nap And Coffee, The time of day that someone takes a coffee nap may also be important.
One small study in 12 healthy adults found that participants who had 400 mg of caffeine — the equivalent of four cups of coffee — six, three or zero hours before bed all experienced disrupted sleep.
Nap And Coffee, This research indicates that it may be best to take coffee naps more than six hours before bedtime.
Finally, the amount of caffeine consumed before a coffee nap appears to impact its effectiveness.
Nap And Coffee, Most research suggests that 200 mg of caffeine — about two cups of coffee — is the approximate amount you need to feel more alert and energized upon waking.
Do Coffee Naps Really Give You More Energy?
Nap And Coffee, Though the logic behind coffee naps seems plausible, research to support the claims that they increase energy more than naps or coffee alone is limited.
However, the few studies that exist are promising
Nap And Coffee, A study in 12 adults showed that participants who took 200 mg of caffeine followed by a 15-minute nap before being placed in a driving simulator for two hours felt 91% less sleepy behind the wheel than those who didn’t have caffeine and a nap.
The study also found that those who didn’t completely fall asleep during the nap period still experienced improved energy.
Nap And Coffee, A similar study in 10 people determined that those who took 150 mg of caffeine before sleeping for less than 15 minutes felt significantly less drowsy during their two hours in a driving simulator, compared to the control group.
Nap And Coffee, Another small study showed that taking 200 mg of caffeine followed by a 20-minute nap is more effective at improving energy and performance in computer tasks than napping plus face washing or exposure to bright light.
Lastly, additional research suggests that consuming caffeine and taking naps together increases alertness and energy during night work more than caffeine or sleep alone.
While the results of these studies imply that coffee naps are effective at boosting energy, they’re small and use caffeine in pill form.
More research is needed to assess how liquid coffee before naps improves energy and alertness upon waking.
Nap And Coffee: Should You Take Coffee Naps?
Nap And Coffee, It’s not surprising that many people want to try taking coffee naps to boost energy levels or improve alertness.
However, research to support the effectiveness of coffee naps is limited.
If you’re interested in incorporating coffee naps into your day, keep in mind the type and amount of coffee you drink.
Nap And Coffee, The dose of caffeine used in most studies is equivalent to approximately two cups of coffee. Consuming this amount of liquid coffee likely has the same effects as taking caffeine pills before a nap, but has not been tested.
Furthermore, drinking coffee with added sugars or flavors before sleeping may decrease the effectiveness of a coffee nap — black coffee is a healthier option.
Nap And Coffee, Finally, excessive caffeine intake can cause restlessness, anxiety, muscle tremors and other issues in some people. Caffeine may also disrupt sleep if consumed less than six hours before bed.
Most health experts agree that up to 400 mg of caffeine a day — the equivalent of about four cups of coffee — is safe for most people.
Nap And Coffee, Remember this recommended maximum daily caffeine intake if you increase your coffee consumption to start taking coffee naps.
Final Thinks
Nap And Coffee, Coffee naps may increase energy more than coffee or sleeping alone, though research to support this effect is limited.
About 2 cups of coffee right before a 20-minute nap may be the best way to reap benefits.
Nap And Coffee, To avoid nighttime sleep disturbances, stop drinking coffee at least six hours before bed.
Nap And Coffee, Coffee naps may certainly be worth a try, as long as you don’t go overboard with your caffeine consumption.
