If you're always tired no matter how much you sleep, it might be worth looking at these three things
There's a pattern that keeps coming up in the research that doesn't get enough attention:
The combination of three interconnected biological processes seems to be responsible for a huge proportion of fatigue that isn't explained by obvious causes:
Oxidative stress — When your cells produce more free radicals than your antioxidant systems can neutralise, mitochondrial function declines. Your mitochondria are literally the energy-producing engines of your cells. Damaged mitochondria = reduced energy output at a cellular level. No amount of sleep fixes this because the problem is happening at a metabolic level.
Cortisol dysregulation — Chronic stress disrupts the daily cortisol rhythm. Normally cortisol peaks in the morning and drops at night. Under chronic stress, evening cortisol stays elevated, blocking melatonin and preventing the deep sleep stages where cellular repair happens. You sleep but you don't recover.
Systemic inflammation — Inflammatory cytokines directly signal the brain to reduce activity and motivation. Chronic low-grade inflammation produces a persistent, milder version of the fatigue you feel when you're fighting a virus.
The reason these often go unaddressed is that standard blood tests don't routinely screen for any of them.
I've found addressing all three together — antioxidant-rich diet, adaptogenic herbs, anti-inflammatory foods — produces much better results than targeting any one alone.
Anyone else been through this? What helped most?
