Living with chronic fatigue can be challenging in many ways, but an unhelpful addition to that is having to explain the difference between tiredness and fatigue. Often, well-meaning friends & family offer advice and support without understanding that fatigue is a completely different beast to feeling tired. It results in advice like “Have a cup of tea” or “You’ll feel better in the morning”. So, how can you describe chronic fatigue to someone who’s never experienced it?
1. Tiredness is Mental; Fatigue is Physical
Tiredness is something that you can push through. You probably don’t want to get up and finish that chore, but you totally could if you just pep yourself up for it. Often, pushing through tiredness is a matter of sheer mental effort. How do you think early birds get up at 5:30am? (No, seriously… please tell me in the comments. I’ve never been an early bird!)
Fatigue is not something that you can push through – it’s quite literally your body refusing to work ‘normally’. It’s not something that any amount of pep or mental willpower can overcome.
2. Tiredness is Transient; Fatigue is Chronic
When you’re tired, a cup of tea or an early night will fix it. There’s relief in knowing what you need to do to fix things. However, fatigue is often present regardless of how much rest you get. You can have the perfect night of undisturbed sleep and still wake up feeling drained of all physical energy.
This is yet another defining characteristic of fatigue – it has little to do with your sleep quality or activity levels and is a key point when you try to describe chronic fatigue.
3. Tiredness is a Useful Signal; Fatigue is a Malfunction
Tiredness is a signal that the brain sends, telling you that you should rest, in much the same way as hunger is a signal to eat some food. Fatigue, however, is a malfunction in the way the mitochondria work. If you think back to school, you might remember that mitochondria are the power house of the cell. They are responsible for providing the cell with all its energy needs. Chronic fatigue is thought to be where the mitochondria are not working properly – the workers at the power plant have gone on strike.
Where Does Chronic Fatigue Come From?
The short answer is that we don’t currently know. The long answer is a little more interesting though.
Essentially, what we do know about chronic fatigue is that it’s typically triggered by something. The most common culprit is a massive infection. This might be viral, as is the case with Epstein Barr (glandular fever) or it may be bacterial (as is the case with Lyme Disease and coinfections).
Fatigue is common when you’re unwell, but it usually resolves once you’re better. However, when that fatigue doesn’t get switched off, you end up developing chronic fatigue – the turn signal gets stuck.
Many people with chronic Lyme and other chronic illnesses experience debilitating fatigue for months, years or even decades. The kicker is that even if you successfully treat the chronic Lyme infection, the fatigue can stick around. That’s the case with me – I’ve successfully treated my Lyme infection, but every now and again I’ll have fatigue flares. Granted, they’re much less common now, but it’s a helpful reminder that I still need to treat myself with care.
How To Describe Chronic Fatigue: Final Thoughts
It’s important to remember that when someone chooses not to hear you it’s not about you. People like to believe that if they became unwell, they could get better. The thought of chronic illness is terrifying and they’d rather live in denial, believing that there is something you’re missing. (A cup of tea or an early night!).
However, when talking to someone who wants to learn, I hope these three comparisons help. Many healthy allies want to understand, but if they’ve never experienced chronic fatigue, they need a little help.
