Why Don’t I Feel Rested After a Good Night’s Sleep? Here’s Why One Night Isn’t Enough

Shannon, 46, had been my client a couple of years ago. Recently, she reached out again, exhausted and frustrated. Life hadn’t slowed down for a second: her son got engaged, then a few weeks later there was a bar mitzvah, complete with hosting a massive weekend at her house — self-catered, of course.

A couple of months later, her daughter gave birth during the holidays and moved in with her toddler. Five weeks later, she was still there. And now, with her son’s wedding just weeks away and another massive Shabbos to host, Shannon was running on fumes.

Then she said something that made me smile, but also perfectly illustrated the problem:

“I finally got one night of 11 hours of sleep, Chevy. Why am I still so tired?”

One Night Won’t “Fix” Sleep Deprivation

Many of us believe sleep works like a phone battery. You run it down, then plug it in, and—boom—you’re back to 100%. But our bodies don’t operate like that.

When you’ve been sleep deprived  for weeks or months, one long night of rest isn’t enough to reset your system. Sleep debt is more like interest on a loan — it quietly piles up until your body is finally desperate enough to demand repayment.

Why We Don’t Feel Rested After “Enough” Sleep

Sleep debt doesn’t just make you groggy. Chronic sleep loss affects:

• Hormones: Cortisol rises, melatonin gets confused.

  
  

• Cognitive function: Memory, focus, and problem-solving all decline.

  
  

• Emotions: Anxiety, irritability, and mood swings increase.

  
  

• Physical health: Immunity, blood sugar, and recovery suffer.

  
  

Even if you sleep 10 or 11 hours after weeks of deprivation, your body is still in survival mode. That’s why you wake up groggy, foggy, or sometimes even more tired than before.

We Treat Sleep Like It’s Optional

After the holidays, my 13-year-old son was going to bed at all kinds of hours — sometimes 1 or 2 a.m. I told him, “You need to start getting to bed earlier so your body can gently get back on track.”

He looked at me like I was unreasonable. “Why? I’m not going to school tomorrow. I’ll go to sleep when school starts again.”

And honestly? He’s just saying out loud what most adults think quietly. We treat sleep like something to use and abuse, something we can postpone until life demands we show up. We don’t view sleep as part of health — we view it as part of schedule.

But that’s where we get it wrong. Sleep isn’t just what we do when we’re done for the day — it’s what makes the rest of the day possible.

How to Survive When Life Is Busy, Stressful, and Exhausting

Sometimes, you can’t just slow down. There are simchas, guests, kids, and deadlines — life doesn’t pause because you’re tired. But there are small choices you can make to protect your body and your sleep:

1. Hydrate. Fatigue worsens when your body is dehydrated. Keep a glass or bottle nearby — it’s a small step that makes a big difference.

   
   

2. Eat. Coffee and leftover snacks don’t count. Your body needs real nourishment to repair itself. Protein, healthy fats, and vegetables tell your system, “I’m safe, I’m being cared for.”

   Down time at night. At least an hour where no one is calling your name, asking questions, or needing anything. That quiet signals to your brain, “Nighttime is coming. You can slow down.”

   
   

3. Take an Epsom salt bath. Not a luxury — therapy for your nervous system. Magnesium helps muscles relax, and the ritual itself trains your body to unwind.

   
   

4. Prioritize sleep — the non-negotiable. This one is the hardest, because when life gets busy, sleep is the first thing to go. We push it off, telling ourselves, “I’ll catch up later.” But here’s the truth: later rarely comes.

   
   

Skipping sleep doesn’t buy you time — it costs you energy, focus, immunity, and emotional balance. Sleep isn’t something you do after everything else is done; it’s what makes everything else possible. Guard it like your most important appointment. Protect your energy. You can’t pour from an empty cup, and you can’t live on fumes.

The Takeaway

If you’ve been burning the candle at both ends, one long sleep-in isn’t going to magically reset your body. Your fatigue isn’t a sign of weakness — it’s your body telling you it’s been running on empty.

Recovery happens gradually, through steady, consistent sleep, nourishment, hydration, and moments of calm. Even small changes, maintained over days and weeks, start to rebuild trust with your nervous system and restore real energy.

Shannon learned that it wasn’t about one miraculous night of rest. It was about protecting herself in small ways, giving her body signals that it’s safe to relax, and prioritizing sleep above everything else.

If you’ve been wondering, “Why don’t I feel rested after a good night’s sleep?”, take a deep breath. You’re not broken — you just need to give your body time and gentle care to catch up.
