How to help the brain stay sharp even after lunch
Somewhere between lunch and the third speaker, you notice it. People shift down a bit. The questions stay out. Someone yawns. Someone else looks at his phone just a little too long.
You can have such good content, but the brain simply does not work on command. The famous after-lunch dip is not an organisational failure. It is biology. Fortunately, you can do something about it.
In this article you will discover how, with a little knowledge of the brain, smart planning and brain-friendly food, you can ensure that your meeting remains sparkling even after lunch. Without jumping jacks between the chairs (unless you want to), but simply by smart planning.
Why is the energy sinking?
After lunch, your alertness drops. Not only because of the meal, but also because of your biological clock. Between 13:00 and 15:00 your body is less alert, a kind of natural siesta. Your digestion is active, your brain subconsciously switches back.
What you notice:
- Participants become quieter or more restless
- Focus drops
- Interaction fails to materialise
- Energy gets syrupy
So it's not because of your content. It's because of the moment. And you can take that into account.
What can you do as an organiser?
An energy dip cannot be prevented, but it can be managed. You don't have to radically change the programme. Small adjustments already do a lot. Here are four smart strategies that we often see working at Jaarbeurs:
Four practical strategies:
- An active break Don't make people sit all the time. Let them move for a while, go outside, grab their own coffee, have a chat. Movement activates circulation and improves focus.
- Choose something light Avoid heavy theory blocks right after lunch. Go for something light: a panel discussion, a creative work form, or a playful quiz. It doesn't have to be slapstick, as long as it releases energy. Something that requires people to think, talk or move themselves.
- Choose a space that supports energy Light and colour make a lot of difference. Use bright lighting, fresh colours and good acoustics. Make sure it doesn't feel warm, stale or dark.
- Feed the brain (literally) A fatty, heavy lunch makes people sluggish. Choose food that gives energy without filling. At Jaarbeurs we like to think along about brain-friendly catering: light, nutritious and appropriate to the time of day.

Make the space work for you
An energetic afternoon starts not on stage, but in the environment. Think:
- Adjustable lighting: bright white light gives fresh impetus
- Water in the hall: simple but effective to stay fresh
- Flexible set-ups: let people move or regroup
- Break rooms with atmosphere: getting away from it all does wonders
This is how you not only help your participants get through the after-lunch dip, but also let them move on with renewed focus. Our conference rooms pay a lot of attention to details like that. Because the space you are in affects how you feel and thus how you listen, think and remember.
Energy can be planned
If you understand the brain a little, you can get so much more out of an afternoon. Not with major interventions, but with smart choices in your set-up, breaks and environment. The result? More attention, better conversations and participants who stay sharp.
Carefree organising is carefree meeting
Whether you are organising a conference, symposium or knowledge session: at Jaarbeurs, we help you not only get a space, but calm your mind and energise the group.
