Hydration and performance in meetings: discover why drinking water boosts concentration, attention and well-being at work. Comet & Castalie join forces for more productive and responsible meetings.
At Comet, we are convinced of one thing: a successful meeting is not just a good overhead projector and a well-laid-out room (even if we do that very well). It is also an environment where your teams feel good, connected, and… hydrated.
It may be a detail to you, but to us, it means a lot…
We are talking here about a lever for concentration, for performance, and even for quality of life at work. That is why we are customers of Castalie at some of our sites, the expert in sustainable microfiltered water, to bring responsible hydration into all your meetings.
Spoiler: your neurons are going to love it.

1. A well-hydrated brain is a brain that keeps up.
The figures leave no room for doubt: the brain is made up of nearly 75% water, and a loss of just 1% of hydration is enough to impact cognitive functions.
- Less concentration.
- Less responsiveness.
- Less memorisation.
And yet, who thinks about drinking during a meeting? Too often, no one. The result: after an hour, attention frays, ideas stagnate… and fatigue sets in.
Building a hydration routine into your events is a simple way to keep your teams engaged, alert… and to boost productivity with no extra effort.
2. Hydration breaks, to avoid "autopilot" mode.
Nobody dreams of a 3-hour meeting with no break (and it is in fact a practice we campaign against in our Cométhode). Organising one means running the risk of losing the collective attention slide after slide.
At Comet, we advise you to schedule micro-breaks every 45 minutes. No need for a royal buffet. A quiet space, a few glasses, a water fountain (Castalie, for example): that is enough to restart the idea machine.
And if on top of that you add a nice chill-out corner, you turn your break into a real booster of collective energy.
3. Why we chose Castalie (and why it changes everything).
Water, with us, seems simple. But well thought out, it becomes a committed act.
With our suppliers such as Castalie, we do more than offer fresh water. We provide:
- A local microfiltered water, still or sparkling, directly on site.
- A committed service, water on site and with no pointless logistics.
- A premium and responsible alternative to traditional bottles.
Every fountain installed in our spaces makes it possible to avoid thousands of plastic bottles for single use. And that is anything but anecdotal. It is even one of the reasons why we are B Corp certified.

4. A meeting room + a fountain = a clear eco gesture.
We see it with the companies we host: bringing in a water fountain like those from Castalie also means creating a committed footprint, consistent with the expectations of today's employees.
On top of limiting waste, it is a way to:
- Give something concrete to your CSR approach.
- Enhance your event without logistical overload.
- Offer a healthier and more pleasant experience to your teams.
5. Our Comet tips for a high-performing meeting (and therefore well hydrated).
We are sharing with you what we apply in our Comet addresses:
- Put mainly or as far as possible the water fountains at the heart of the space, not in a corridor. Visibility encourages people to drink.
- Play the experience card and boost the appeal of water: add a few mint leaves or slices of organic lemon to give the break a twist.
It is simple, with no additional cost, and it gives your meetings a well-judged premium + well-being touch.

A successful meeting is a meeting where you think of everything, including what you drink. And in a context where well-being at work is an ever stronger criterion of motivation and of performance, not building in hydration means missing out on an essential (and accessible) lever.
