Why Your Energy Crashes When Schedules Change (The Science Behind It)

September 1, 2025

The Science of Schedule Disruption

September in Vegas means one thing - life is about to get CRAZY busy, even if the weather isn't changing! It's September in Vegas, which means we're still dealing with 100+ degree weather, but somehow EVERYTHING else feels different. Kids are back in school, football season is starting, work is ramping up after summer vacations, and suddenly everyone I see in my practice is asking the same question:

"Why am I so exhausted when nothing has really changed?"

Here's the thing - a LOT has changed, just not the temperature! And your body is feeling every bit of it, even if your brain hasn't caught up yet.


The Science of Schedule Disruption

Let me geek out for a minute because this stuff is fascinating! Your body runs on something called circadian rhythms - basically your internal clock that tells every cell when to do what. This clock doesn't just control sleep; it controls hormone production, metabolism, immune function, and even when your body repairs itself. When your routine changes (hello, back-to-school chaos!), you're essentially telling your internal clock to reset. And just like when you travel across time zones, your body needs time to adjust.


Here's what's happening inside your body:

  • Cortisol Gets Confused: Your stress hormone cortisol is supposed to be highest in the morning and lowest at night. But when your schedule changes, cortisol production gets wonky. You might feel wired at bedtime or exhausted in the morning - sound familiar?
  • Blood Sugar Rollercoaster: New schedules often mean eating at different times, grabbing food on the go, or skipping meals entirely. This sends your blood sugar (and energy) on a wild ride throughout the day.
  • Sleep Quality Takes a Hit: Even if you're getting the same number of hours, the QUALITY of your sleep changes when you're mentally adjusting to new routines. Your brain is literally processing more information, which can make sleep less restorative.
  • Adrenaline Overdrive: Busy schedules trigger your fight-or-flight response more often. While this helps you handle the chaos, it also depletes your energy reserves faster than usual.


The Vegas Factor

Living in Vegas adds another layer to this! We're dealing with:

  • Extreme heat that forces us indoors (goodbye, natural light regulation!)
  • Constant air conditioning (which can actually affect your metabolism)
  • Tourist season chaos affecting traffic and daily life
  • The unique challenge of maintaining energy in desert heat

Your body is working HARD just to function in this environment, and then we pile on schedule changes? No wonder you're tired!


Your End-of-Summer Action Plan

Okay, enough science - let's talk solutions! Here's my 5-step plan to help your body adjust and thrive during busy season:


Step 1: Stabilize Your Morning Routine

Even if everything else is chaos, try to wake up and eat breakfast at the same time every day. This gives your circadian rhythm an anchor point to work from.

My favorite morning energy combo:

  • Protein within 30 minutes of waking
  • Natural light exposure (even if it's just stepping outside briefly)
  • Hydration before caffeine


Step 2: Support Your Stress Response

Your adrenal glands are working overtime right now. Give them some love!

What helps:

  • B-complex vitamins (especially B12)
  • Magnesium before bed
  • Adaptogenic herbs like ashwagandha
  • Deep breathing exercises (even 2 minutes helps!)


Step 3: Optimize Your Sleep Environment

Since your sleep quality is taking a hit, make your bedroom a recovery sanctuary:

  • Keep it COLD (your AC bill is worth it!)
  • Blackout curtains or eye mask
  • No screens 1 hour before bed
  • Consider magnesium or melatonin if needed


Step 4: Fuel Your Body Consistently

Busy schedules make us skip meals or grab whatever's convenient. But your energy depends on steady fuel!

Quick energy-sustaining combos:

  • Apple with almond butter
  • Greek yogurt with berries
  • Hard-boiled eggs and avocado
  • Protein smoothie with spinach


Step 5: Know When to Get Help

Sometimes lifestyle changes aren't enough, and that's OKAY! If you're doing all the "right" things and still feeling exhausted, it might be time to look deeper.

Red flags that it's more than just schedule changes:

  • Exhaustion that doesn't improve with rest
  • Mood changes that feel out of proportion
  • Sleep issues lasting more than 2 weeks
  • Weight gain or loss without trying
  • Brain fog that interferes with daily life


When Your Body Needs More Support

Here's what I see in my practice: sometimes the exhaustion from schedule changes reveals underlying issues that were already there. Things like: Hormone imbalances (thyroid, adrenals, sex hormones), nutrient deficiencies (B12, Vitamin D, iron), blood sugar instability, and/or chronic inflammation.The good news? These are all treatable! With the right testing and personalized approach, we can get to the root cause and help your body handle stress better.


The Bottom Line

Your exhaustion is REAL, and it's not "all in your head." Your body is responding normally to abnormal demands. Be patient with yourself as you adjust, implement the strategies that feel doable, and don't hesitate to seek support when you need it. September might be busy, but it doesn't have to be survived - it can be thrived through!
