When Everything Feels Like Too Much
Many people feel constantly exhausted and easily overwhelmed every single day. Even when they're doing everything "right" for their health and wellbeing. They're eating well, exercising regularly, and trying to manage their stress. They can't understand why small things overwhelm them so intensely. Or why they always feel so tired and stressed out.
One simple email or a broken appliance can completely derail their day. Leaving them feeling like they're barely keeping it together.
In this episode, I explain how your body reacts to stress. Your body doesn't react based on what's happening to you. It actually reacts based on whether you have enough energy available. Enough energy left to handle what's being demanded of you right now.
Think of your nervous system like a bank account holding resources. Every challenge, decision, or demand takes energy out of your account. When you're already running low from everyday stressors adding up, even tiny problems can push you into overwhelm and emotional shutdown.
This isn't about changing your mindset or trying harder. It's about understanding what's actually happening in your nervous system biology. When you get overwhelmed by daily life so you can respond. So you can start making small changes that build resilience.
Whether you're personally dealing with chronic exhaustion and burnout right now or you're a practitioner helping clients who want better techniques, this episode gives you practical action steps to start feeling better.
The Energy Bank Account Model
Your body doesn't react to stress based on what's happening. It reacts based on whether you have enough energy to handle it. Think of your nervous system like a bank account with deposits. Every challenge, decision, or demand takes energy out of your account.
When you're already running low from everyday stressors piling up constantly, even tiny problems can push you into overwhelm and shutdown mode. Your perceived capacity versus perceived demand determines everything that happens. When demand exceeds capacity, overwhelm happens automatically in your nervous system.
The math is straightforward and simple to understand once explained. More demands than energy equals overwhelm you feel physically and emotionally. More energy than demands equals ease in handling life's challenges. Understanding this equation shows you have two levers to pull. Reduce demand or increase capacity or both for better outcomes.
Why Small Events Feel Overwhelming
Small events can feel overwhelming when your account is depleted. This isn't irrationality, it's biology based on available resources right now. What matters is the size of the demand relative to your available resources at that specific moment.
A small withdrawal from an empty account is devastating to manage. Same small thing from a full account is manageable easily. Your body responds to the math of resources available now. Do I have resources for this or not? The answer determines your response to every single demand.
The Daily Invisible Drains
Daily energy drains add up over time and quietly exhaust you. These are often invisible until you start tracking them carefully.
Every night of poor sleep drains your account significantly over time. This compounds over days and weeks affecting everything you do. Interactions that leave you depleted cost more than people realize. Noise, clutter, and toxins require your body to use energy. Your body has to manage these environmental stressors constantly throughout the day.
Every decision you make costs energy from your limited reserves. When you have too many decisions, you drain fast without realizing. Suppressing or avoiding emotions takes constant energy to maintain control. This is a major hidden drain most people don't recognize.
None seem like much alone when you consider them individually. But together, they deplete your account before you face real challenges.
What Happens During Shutdown
What's actually happening in your body during shutdown matters greatly. Understanding this removes shame about your reactions and responses completely. Your nervous system says "we don't have resources for this now." And shuts down to conserve what's left for basic survival only.
Blood flow to frontal cortex decreases significantly during this time. Energy goes to survival systems instead of higher thinking functions. Higher functions go offline because they're not essential for survival.
You can't think clearly, can't make decisions, feel frozen or numb. This isn't laziness or weakness, it's biology protecting you right now. Your body is protecting you by shutting down nonessential functions completely. When resources are too low to handle any additional demands safely.
Why Even Good Things Drain You
Even good things like travel or celebrations can drain your energy. This surprises many people who think positive events should energize. Even positive experiences require energy and adaptation from your nervous system. Your nervous system uses resources regardless of whether stress is good.
Travel is exciting but also disruptive to routines and sleep. And requires constant adaptation to new environments draining your reserves. Celebrations are wonderful but also stimulating to your nervous system constantly. May involve people-pleasing and disrupt routines costing energy from your account.
Understanding this helps you plan and recover appropriately after events. Even from positive events that you thought wouldn't drain you.
Building Your Energy Reserves
How to build up your reserves so you're ready for challenges. This is preventive resilience that protects you from future overwhelm.
Quality sleep is the biggest deposit you can make daily. This restores your account more than anything else you do. Identify and address the ongoing drains depleting you constantly every day. Each one you eliminate leaves more energy in your account available.
Daily practices that regulate your nervous system make consistent deposits. These are deposits that compound over time building real reserves. Things that genuinely restore you, not just distract temporarily from stress. These add to your account rather than just pausing withdrawals briefly.
Protecting your energy through healthy boundaries prevents unnecessary withdrawals constantly. This stops energy leaks you didn't realize were draining you.
Practical Ways to Reduce Drains
Simple ways to reduce daily energy drains and add deposits back. These are practical and accessible to start implementing right now.
Start by identifying your biggest drains throughout your typical day. What consistently takes energy without giving back anything helpful to you? Even small reductions matter significantly when they're consistent over time. Saying no to one thing or simplifying one routine helps. Less screen time before bed protects your sleep quality significantly.
Things that restore energy to your system don't need much time. These don't have to be big or time-consuming to help. Five minutes of deep breathing or a short walk outside. Connection with someone safe or moments in nature observing quietly.
Small changes compound over time building real resilience in your system. Reducing drains and adding deposits gradually rebuilds your capacity to handle life.
Why Mindset and Trying Harder Fail
You can think positively all you want about your situation. But if your account is empty, you'll still feel overwhelmed. Biology requires energy, not just positive thoughts about having energy.
Trying harder uses more energy from your already depleted reserves. When your account is low, this makes things worse instead. Support your biology first by building your energy reserves up. Then everything else becomes more possible to manage successfully.
Understanding Your Reactions
That email that derails your day makes sense now completely. That email isn't objectively overwhelming to handle in normal circumstances. But when your account is empty, any withdrawal is too much.
The broken appliance causing overwhelm makes sense biologically too. The appliance breaking isn't catastrophic in the grand scheme of life. But it's one more demand on an already depleted system.
The bank account model helps you track and manage energy. You can see deposits and withdrawals happening throughout your day. You can reduce demands or increase capacity or both together. Having both options provides flexibility in managing your nervous system.
The Path Forward
Understanding the biology of overwhelm empowers you to make changes. Specific changes that actually work with your nervous system biology. Small changes add up over time to rebuild your reserves. You start feeling stronger and more capable of handling life.
With fuller reserves, you can handle life's challenges more easily. Without going into overwhelm and shutdown mode every time something happens.
