Before You Add Another Planner, Check the Pillow

I was driving with my son over the weekend, listening to my favorite band, the Grateful Dead. He let me know, loudly, that he is not a fan. Then he fell asleep, which he almost never does in the car unless he’s completely worn out.

When he woke up, he was a different kid. No meltdowns, no pushback, just a pleasure to be around for the rest of the afternoon. Nothing about his day had changed except that his brain finally got some rest.

It reminded me of the first question I ask when a student forgets assignments, can’t get started on tasks, or melts down over something small: how are they sleeping?

Why sleep and executive function are so tightly linked

Executive functions like working memory, planning, impulse control, and emotional regulation rely heavily on the prefrontal cortex, and that part of the brain is especially sensitive to sleep loss. After a short night, kids and teens get more distractible, more reactive, slower to switch gears, and worse at holding several steps in mind. Sleep also helps lock in what was learned that day, so a tired brain struggles both taking information in and pulling it back out later. To see how much sleep different ages need, check out the National Sleep Foundation’s sleep duration recommendations.

It’s also a two-way street. Weak executive function makes sleep harder to protect: late-night scrolling, underestimating how long homework will take, trouble winding down. And poor sleep weakens executive function further.

For teens, biology adds another layer. The adolescent body clock shifts later, which collides with early school start times. This isn’t laziness or defiance.

One student I worked with had been labeled disorganized for years. Once we looked at his evenings, he was averaging about five hours of sleep. After he started getting more, he told me he felt more refreshed and alert. Fixing that did more than any new planner could.

What parents can try at home

These are starting points, not a fix for every child.

Keep a consistent wake time, even on weekends. For teens, aim for within an hour or two of the weekday schedule, since their body clocks naturally drift later.

Build a shutdown routine backward from bedtime, so homework doesn’t spill into the night.

Charge devices outside the bedroom.

Practice estimating homework time. Have your child guess how long an assignment will take, time it, and compare. A few rounds of this builds a skill that protects sleep for years.

Check in with your pediatrician if sleep problems persist despite good routines.

What educators can try in the classroom

Treat chronic fatigue as a possible factor before assuming a motivation problem.

Flag late-night deadlines that quietly cost students sleep.

Spread major deadlines out so they don’t all land on the same night.

Raise sleep with families early, as a support strategy rather than a criticism.

Small experiments, big lessons

My son’s afternoon was a small, accidental experiment. A car nap isn’t a substitute for a full night’s sleep, but it was a good reminder that rested kids are easier to teach, easier to live with, and better able to handle frustration. Most families can’t count on a nap in the back seat, which is why a sleep-friendly routine matters.

Knowing this is one thing. Building the habits is another, and that’s where many families get stuck.

At MVP Tutoring, I work one-on-one with students to build the executive function skills that make school, and sleep, more manageable: planning, time estimation, task initiation, and routines that actually hold up in real life. With over 15 years of experience in independent schools and higher education, I help students and families turn good intentions into systems that work.

If your child is stuck despite real effort, let’s talk. Send me a message or visit MVP Tutoring to set up a conversation about where your student is struggling and what support could look like.
