Sleep plays a powerful role in how we think, decide, and respond — especially under stress 🧠
Neuroscience research summarized by Matthew Walker shows that sleep deprivation reduces efficiency in the prefrontal cortex, the part of the brain responsible for judgment, impulse control, planning, and decision-making. When this region is underpowered, the brain relies more on reactive pathways instead of thoughtful ones.
That’s why tired brains struggle with clear thinking, patience, and good judgment — and why even simple decisions can feel overwhelming when you’re exhausted.
This isn’t a personal shortcoming. It’s a biological response to insufficient sleep. Supporting sleep supports clearer thinking, safer decisions, and better emotional regulation — for parents and kids alike.
We break down this research and many other foundational sleep studies inside The Peaceful Sleeper book — now available for pre-order! 💛
