Coffee Naps: Science, Benefits, and Digestive Concerns for Adults
Some people think that drinking coffee and then taking a short nap can make them feel more awake.
Scientists say the idea makes sense because caffeine takes a while to work, so you can fall asleep first.
But it might not work for everyone, especially if you have a sensitive stomach.
Doctors warn that coffee can cause stomach acid and heartburn when you lie down right after drinking it.
The coffee nap is not a replacement for a good night's sleep or healthy habits.
It can help some people feel refreshed, but it can also cause problems for others.
Coffee nap combines a 20‑minute nap with caffeine to boost alertness.
Sleep experts say the technique is biologically plausible but lacks strong evidence.
Individual caffeine tolerance and sleep quality affect how well it works.
Digestive specialists warn that coffee before lying down can trigger acid reflux.
The method is not a substitute for adequate nighttime sleep or healthy habits.
