Why am I so irritable all the time?

Irritability is a common experience — and usually a sign that a need isn't being met.

Common causes

• Sleep debt — even one short night lowers your frustration threshold.
• Chronic stress — when your nervous system stays activated, small things feel big.
• Hunger and dehydration — your brain runs on fuel.
• Unspoken boundaries — resentment often shows up as snappiness.

What helps

1. Track it. A daily check-in reveals patterns you can't see in the moment.
2. Pause before reacting. Three slow breaths give your prefrontal cortex time to catch up.
3. Talk to someone. If irritability lasts more than two weeks, consider reaching out to a therapist.
