It’s not the size of the trigger – it’s how fast the wave arrives.
Emotional flooding is a sudden, overwhelming surge of intense emotion that arrives faster than it can be regulated, often set off by something that looks minor from the outside.
1 Understand the core chain
- A seemingly minor trigger happens
- Emotional intensity rises disproportionately fast
- Rational thinking becomes hard to access
- The reaction looks bigger than the situation justifies
- Afterwards come confusion or regret about how intense it was
“Flooding isn’t about the size of the trigger – it’s about how fast the wave arrives before regulation can catch up.”
2 Recognise how it shows up
- Body: Sudden heat, racing heart, tunnel vision in the moment.
- Thoughts: “It’s too much”, “I can’t think straight”, “Why did I react like that?”
- Behaviours: Raised voice or sudden tears out of proportion, needing to leave the situation abruptly.
One isolated sign is not enough to define a pattern.
3 The cycle how it keeps going
- Small trigger
- Intensity rises fast
- Rational access drops
- The reaction looks oversized
- Regret increases the fear of the next flood
…and back to the start.
4 Explore questions to go further
- What did this small trigger really connect to, under the surface?
- What is the first physical sign that flooding is starting?
- What would a 10-second pause at that first sign look like?
5 Go deeper needs and beliefs
Need: A buffer of time between the trigger and the reaction.
Belief: “My emotions are too fast and too big for me to ever manage them.”
6 Next steps where to go from here
- Identify your first physical warning sign of flooding.
- Practise a 10-second pause at that first sign.
- Look back at the moment afterwards with curiosity rather than judgement.
