Ever feel like your brain just shuts down after work?
Allostatic load is the cumulative physiological wear and tear that happens when your body repeatedly adapts to stress.
Every time you experience a stressor, your body changes its internal state to help you cope. Stress hormones like cortisol and adrenaline rise, your heart rate can increase, and your attention becomes more alert.
That response is useful in the short term. The problem is when your body has to activate these systems over and over again without enough recovery.
Think of it as the biological cost of staying “on” for too long.
Over time, higher allostatic load has been associated with changes in sleep, energy, mood, cognition and other aspects of health.
So when you close your laptop and feel like your brain has completely checked out, it may be a sign that your system needs recovery, not just more caffeine.
