Why It Happens

Feeling fatigued at night is expected, but excessive evening exhaustion may indicate poor sleep quality, circadian misalignment, or blood sugar instability.

Sleep Debt Accumulation: Skipping restful sleep the night before compounds fatigue.

Circadian Disruption: Irregular schedules or light exposure can make you feel wired yet tired.

Reactive Hypoglycemia: A blood sugar crash after dinner can lead to fatigue and fog.

Chronic Stress: Cortisol imbalances from daily stress wear down energy reserves by evening.

How to Manage

Wind Down Consistently: Keep a regular bedtime and avoid screens 1 hour before sleep.

Limit Sugar or Refined Carbs at Dinner: Prevent blood sugar spikes and crashes.

Use Magnesium or Adaptogens: Support relaxation and lower cortisol levels naturally.

Evaluate Sleep Quality: Consider tracking deep vs. REM cycles with a wearable.
