Fatigue

Fatigue meaning

Ever felt like you’re running on empty before the day even starts?
Like your brain is foggy, your body heavy, and even the smallest tasks feel like dragging a boulder uphill?
You’re not alone.And no, this isn’t just "life getting busy" or "you needing another coffee."

If you’re constantly asking yourself "Why am I always tired?" or
"Why do I feel so exhausted all the time?" — this article is for you.

Because fatigue isn't just about needing more sleep. It’s a message. From your body.
From your lifestyle. From your nervous system.
And from the way you’ve been taught to power through, instead of pause and recalibrate.

What exactly is fatigue

Fatigue isn’t the same as being tired after a long day. It’s deeper. More stubborn.
Think of it like this: tired is when your phone hits 10%.
Fatigue is when your battery won’t even hold a charge anymore.
No matter how long you plug in, it drains instantly. That’s what chronic fatigue feels like.
And it shows up in more ways than just yawning:
-Waking up unrefreshed, even after 8 hours
-Brain fog, forgetfulness, and lack of focus
-Mood swings, anxiety, irritability
-Shortness of breath or heart racing for no reason
-Constant cravings for sugar, carbs, or caffeine
-Feeling weak, dizzy, or like you’re about to crash
If any of that sounds familiar, your body isn’t just tired. It’s overwhelmed.

And it’s trying to get your attention.

Fatigue causes

Here’s the tricky part. Fatigue has hundreds of potential causes. But for high-performers like you, there are patterns that show up again and again. Let’s break them down.

1. Stress and Cortisol Overload
You might thrive under pressure, but your body has limits.Cortisol is your body’s stress hormone.
It helps you handle deadlines and get stuff done.
But when cortisol stays high for too long, your system starts to burn out.
Symptoms of high cortisol:
-Trouble sleeping (especially falling asleep)
-Belly fat ( cortisol belly )that won’t budge
-Feeling wired but tired
-Crashing hard mid-day

Fix: Focus on cortisol detox strategies:
breathing techniques, magnesium, better sleep hygiene, and strategic downtime.

2. Poor Recovery, Not Just Poor Sleep
Sleep is important. But quality of recovery matters more.
You could be sleeping 7 to 9 hours but still wake up wrecked. Why?
-Because your nervous system never actually switched into recovery mode.
-Blue light exposure at night
-Too much caffeine too late
-Overtraining without enough rest days
-Scrolling instead of slowing down

Fix: Use wearables like the Garmin Fenix 8 ( free with our ENERGY PROGRAMME ) to track sleep and recovery.
Add pre-bed rituals like box breathing or progressive muscle relaxation.

3. Blood Sugar Rollercoaster
You eat. You feel good. Then suddenly, you crash. That’s not just hunger. That’s blood sugar chaos.
And it’s exhausting your brain and adrenals every time it happens.
-Skipping meals
-Too many refined carbs or not enough
-Not enough protein or fat or too much
-Relying on quick fixes like energy drinks

Fix: Build meals around stable energy. Think low GI carbs + protein + fibre + healthy fats.
Try magnesium-rich foods like pumpkin seeds or dark leafy greens.

4. Hidden Nutrient Deficiencies
You can eat "clean" and still be deficient. Especially if you’re stressed or on the go.
Some common fatigue-linked deficiencies:
-Iron (especially in women)
-Vitamin DB12
-Magnesium

Fix: Get a full blood panel done ( we can help you ). Not just for disease, but for optimal levels.
Supplement smart, not random.

5. Mental Load and Emotional Fatigue
Entrepreneurs and high-performers carry invisible weight. Decision fatigue, emotional suppression, and mental overload are just as exhausting as running a marathon. Your brain uses up to 20% of your total energy.
When it’s in constant overdrive, your whole system pays the price.

Fix: Delegate. Journal. Meditate. Unload. Build mind recovery into your calendar like any other meeting.

Real-Life Story: From Burnout to Balance

Tom C. A 42-year-old founder of a successful tech company. On paper, he was crushing it. In real life?
Constant headaches, brain fog, falling asleep at his laptop. Always on coffee (making it worse). Then cold plunges. Then high-dose supplements (your body cannot be cheated).

Nothing worked long-term. After testing, we found:
-Sky-high cortisol
-Low magnesium and B12
-VO2 Max way below optimal
-Nutrient deficiencies.


We rebuilt his morning routine. Added strategic meals. Gave him a sleep wind-down protocol.
And set weekly breathing sessions. In 2 weeks, energy was up 30%.
After two months, he said, "Feel like climbing a mountain"... we obviously suggested it, but laughing he declined it. Funny enough.

Reclaiming Your Energy

If you’re feeling constantly tired, here’s your roadmap.
Step 1: Check Your Basics
Are you sleeping 7-9 hours? Are you moving daily but not overtraining (in reality under-recovering)?
Are you eating regular, balanced meals? Are you mentally overloaded?

Step 2: Track and Test
- Wearables to check HRV, sleep, stress
- Get a full blood panel: iron, B12, D, thyroid, cortisol
- Take a VO2 Max test if you can (Garmin Fenix 8 is our go to as extremely precise)

Step 3: Detox Your Day
-
Cut caffeine after 1PM
-Create a wind-down ritual (breathwork, magnesium, reading)
- Set screen curfews

Step 4: Build Your Energy Up, Daily
- Morning light exposure
- 10-minute walk after meals
