Should You Nap on Vacation? 🥱

Jul 30, 2026

By Arthur Legrand

Hello,

In summer, under the effect of heat and often a richer meal, our body temperature drops slightly in the early afternoon. It's the famous "3pm dip", a completely natural biological signal inviting us to rest.

But here's what happens when you give in for more than 30 minutes:

Sleep inertia: if you go over 20 to 25 minutes of napping, your brain dives into a deep sleep phase. If your alarm goes off in the middle of this phase, coming back to reality is brutal. This is sleep inertia: that "knocked out" feeling can last several hours.
Nighttime disruption: too long a nap eats into your evening "sleep pressure". The result: you struggle to fall asleep at midnight, and you keep the vicious circle of fatigue going.

The Magic Formula: the 20-Minute "Power Nap" ⚡️

The good news is that a short nap is a fantastic recovery tool. Used by athletes and fighter pilots, the power nap (or micro-nap) offers an immediate mental and physical recharge without the side effects.

The proven benefits of a 20-minute break:

Lower cortisol: the nervous system settles down and releases accumulated tension
Boosted memory and creativity: the brain sorts through the morning's information
Muscle recovery: tension releases without dropping into heavy sleep

The Instructions for a Successful Nap Under the Palm Trees 🏝️

1/ Set an alarm for 20 minutes max: even if it feels like you didn't really "sleep", simply closing your eyes in a drowsy state is enough to recharge your brain.

2/ Take care of your environment: don't look for complete darkness or total silence. A shady spot with a bit of airflow (a breeze under the parasol is ideal) keeps your body from overheating while you rest.

3/ The "cellular hydration" reflex before opening your eyes: in the heat, dehydration amplifies brain fatigue and makes waking up feel groggy. To avoid this trap, drink a large glass of water with a dose of Onday in the morning. By providing your cells with a mix of electrolytes, magnesium and potassium, you help your body regulate its internal temperature all day long! The result: you're able to get going instantly right after your nap, with a perfectly clear mind.

Discover!

Rest isn't measured by duration, but by the quality of recovery. Twenty well-supported minutes beat 2 hours of heavy sleep.

Enjoy your summer!
