342 — 5 Reasons You've Got a Short Fuse Lately (and How to Lengthen It)

Have you lost your cool lately over something small? Maybe you snapped at your partner about the dishes in the sink. Or maybe you didn’t say a word—you just let a coworker’s question irritate you all day—and afterward you thought, “What’s wrong with me? This isn’t who I am.”
 
If this sounds familiar, today’s episode is for you. There are many reasons we can develop a short fuse. Fortunately, there are also many ways to lengthen it once you know how.
 
Some of the things I talk about are:
 

• Why a short fuse is a gauge—and what it’s actually trying to tell you.
• How to recognize when your fuse is getting short.
• What one night of bad sleep does to the alarm center of your brain
• The “file folder” of small things you never said out loud and what happens when it’s full.
• Why open loops drain your patience—and the surprising fix.
• The voodoo-doll study on married couples that reveals a surprising reason you might snap at your partner.
• How suppressed anger often comes out.
• How to lengthen your fuse.

Key Takeaways:

• Lack of sleep significantly impacts emotional reactivity.
• Suppressing minor annoyances can lead to resentment and explosive reactions.
• Unfinished tasks, or “open loops,” can contribute to mental clutter and irritability.
• Physical factors, such as hunger or hormonal changes, influence our patience levels.
