Drinks & Heat: the Hack for an Optimal Recovery 🍻

May 28, 2026

By Arthur Legrand

Hello,

The sun is finally here and the weekend looks packed! Whether you're relaxing in the garden, hosting a barbecue with friends, or watching the Champions League final, the mood will be festive, and so will the temperatures!

Between the heat, the irregular meals and the drinks piling up, excess comes at a cost. Alcohol in particular blocks the antidiuretic hormone, forcing your kidneys to eliminate more water than they take in. The result? A flash dehydration that ruins your next day.

The Evening Hack: the "1 for 1" Rule 💧

You've probably already heard of it: and no, it's not a myth! The secret to a good morning after: for every alcoholic drink, drink a big glass of water. And when you think about it, it's so simple that for the sake of tomorrow, it's really worth it.

The benefit: you maintain your blood volume, help your body filter toxins and avoid that famous "dried out" brain feeling on waking.

The Ultimate Trick: the Midnight Snack 🥖

If you really want to bulletproof your morning after, don't go to bed running on empty. Alcohol blocks glucose production by your liver, which often causes mild nighttime hypoglycemia. That's exactly what wakes you up at 4am with a racing heart and the inability to fall back asleep.

My advice:

For those coming home from a night out: that famous 2am kebab isn't just a craving, it's your body asking to soak things up, so go for it! For a more "nutrition" version: a slice of whole-grain bread or a banana when you get home will work wonders for your sleep.
For those who had a proper dinner: don't make the mistake of eating only meat! Keep a little room for starches (baked potatoes, bread, pasta salad). These are complex carbs that will stabilize your blood sugar overnight and help you avoid waking up with a jolt.

Why Sunday Mornings Hit Hard 🤯

The day after a festive moment in the sun, your body is drained of its mineral salts. Without these precious electrolytes, your nervous system runs on low power and your muscles feel like lead.

My "full recovery" protocol: if the night ran longer than planned, don't wait for the headache to settle in. On Sunday morning, go for 3 spoonfuls of Onday instead of 2.

This extra dose of magnesium and potassium will instantly recharge your cells. Magnesium calms the nervous system, while potassium kickstarts deep hydration. It's the solution to turn a "wasted" Sunday into a day you actually get to enjoy!

Discover the formula!

What About Those Who Don't Drink Alcohol?

If your plan is more "sunshine, soft drinks and a big barbecue", you're not immune to the slump either.

The soft drink trap: drinking sugary beverages under blazing heat causes dramatic blood sugar spikes. Your body then has to make a huge effort to regulate everything while also digesting.
My "freshness" tip: alternate your sugary drinks with lemon water or mint-infused water. This rinses your palate and avoids overloading your liver with excess fructose, all while keeping optimal cellular hydration. You'll enjoy the day without feeling exhausted or bloated!

Wishing you a great weekend, have fun and above all, stay hydrated! See you very soon for more tips.

Take care of yourself,

Arthur
