The science behind coffee naps: how to recharge effectively

Have you ever noticed your energy levels dip in the early afternoon? Maybe you grab a cup of coffee, or you take a quick nap, but what if you could do both? 

Enter the coffee nap: A coffee nap, or "nappuccino", is a simple yet effective way to recharge when you need it most.

Surprisingly, pairing coffee with a nap may seem like a recipe for disaster, but research has proven that this combination can actually enhance our daytime productivity and significantly enhance our mental sharpness.

Studies show that for certain groups, like night shift workers or sleepy drivers, a coffee nap can significantly enhance cognitive and physical performance.

One study from the 90s tested participants who consumed 200 milligrams of caffeine before taking a nap. The results were telling: those who had both a caffeine boost and a nap managed to stay alert and perform better than those who had caffeine or a nap alone.

How does it work?

Caffeine blocks a chemical called adenosine in your brain, which makes you feel sleepy. As adenosine builds up throughout the day, we start to feel tired.

A quick nap helps clear some of this adenosine from the brain, making way for caffeine to work even better. After enjoying a caffeine kick and a brief rest, you’re not just awake, you’re alert!

When to take a coffee nap?

• During the afternoon slump: If you feel your energy dip after lunch, that’s the perfect time.
• Before a late night: If you know you’ll be up late, this combination can keep you sharp and awake.
• Before a long drive: A coffee nap can help improve your concentration for those long journeys.
• Avoid before bedtime: If it's nearly time for bed, skip the coffee nap. Caffeine can keep you up longer.

How to take a coffee nap

1. Prepare your coffee with about 200 milligrams of caffeine.

2. Drink it quickly.

3. Set an alarm for 20 minutes and find a dark and comfy place to close your eyes.

4. Don’t hit snooze! After 20 minutes, wake up and enjoy the enhanced energy and mental clarity. 

Studies suggest that the best time to indulge in a coffee nap is after lunch, ideally around mid-afternoon. This is when many people naturally feel a dip in energy.

Despite its perks, there are instances when caffeine should be avoided altogether, particularly for those with certain medical conditions such as high blood pressure, pregnancy or anxiety.

Always consult a healthcare professional if you have doubts about caffeine consumption.
