Summary & Insights

Imagine being completely exhausted after a long, stressful day, only to have your energy instantly surge the moment a dear friend knocks on your door. This sudden shift reveals a powerful truth: tiredness isn’t always about how many hours of sleep you’ve had; often, it is emotional rather than physical. When our lives are misaligned—meaning we spend our time on things that don’t “light us up” or we constantly prioritize others over ourselves—the resulting fatigue can feel exactly like a lack of sleep.

True energy management requires looking beyond the clock and examining the quality of our recovery and the biology of our bodies. For many, the problem isn’t the quantity of sleep, but the “inputs” received in the hour before bed. By mirroring our ancestral habits—shifting from the “hunt” of the workday to a “campfire” state of relaxation—we can lower stress hormones and move from superficial sleep to truly restorative rest. Similarly, physical movement isn’t just for fitness; it is a biological necessity for processing the emotional stress accumulated throughout the day.

Finally, the internal “blood sugar roller coaster” often masks itself as general exhaustion. While ultra-processed foods are well-known culprits, even healthy whole-food carbohydrates can cause energy crashes in people with insulin resistance. By stabilizing blood sugar through protein and healthy fats, and by being mindful of the “two-hour mark” after meals, it is possible to break the cycle of caffeine dependency and midday slumps to regain a consistent sense of vitality.

Surprising Insights

  • Emotional Exhaustion vs. Physical Fatigue: Tiredness can be a symptom of “misalignment,” where acting against your true self or ignoring your own needs drains your energy as much as a physical workout would.
  • The “Campfire” Effect: Sleep quality is heavily dictated by the 60 minutes before bed; using that time for “low-input” relaxation signals the brain to switch off stress hormones.
  • Movement as Emotional Processing: Physical activity is framed not just as exercise, but as a way for the body to biologically “process” the stress and emotions of the day.
  • The Healthy Carb Trap: Even whole-food carbohydrates (like sweet potatoes) can cause significant blood sugar spikes and subsequent energy crashes in those with insulin resistance.

Practical Takeaways

  • Audit Your Energy: Keep a journal to identify who and what consistently gives you energy versus who and what drains it.
  • Create a Pre-Sleep Ritual: Dedicate the hour before bed to relaxing inputs—such as audiobooks, yoga, or calming music—and avoid stressful news or work emails.
  • Break Up Sedentary Time: Integrate short bursts of movement, such as a 10-minute walk after dinner or a 30-minute lunch break walk, to clear emotional stress.
  • Stabilize Your Blood Sugar: Prioritize protein and healthy fats (like avocados and nuts) at every meal to avoid the “crash” that leads to cravings and caffeine reliance.
  • Monitor Post-Meal Energy: Pay close attention to how you feel two hours after eating to identify if specific “healthy” foods are causing blood sugar instability.

Many of us assume low energy is simply a consequence of being busy or not getting enough sleep. But there can be other factors contributing to how we feel that often go unnoticed.

I’ve decided to try something a little bit different as a Bitesize episode this week. I wanted to record a solo episode about the topic of energy because one of the most common things I hear from patients is that they feel exhausted or overwhelmed even when they seem to be getting enough sleep.

So, in this episode, I share a few often overlooked reasons that can leave us feeling low in energy, along with some simple strategies that could quickly begin to help.

Please note: these symptoms can also occur in a range of conditions, including depression, sleep apnoea, thyroid disorders and anaemia. If your symptoms persist, or if you have any concerns, it’s important to seek advice from a qualified healthcare professional.
