Sleep
Why You're Tired Even After 8 Hours
· 6 min read
Eight hours in bed and still waking up exhausted. It's one of the most common complaints — and one of the most misunderstood. The assumption is that sleep is like charging a battery: plug in for long enough and the percentage goes up. But sleep is far more complex than that.
Sleep happens in cycles of approximately 90 minutes, each including light sleep, deep sleep, and REM sleep. Deep sleep is when the body repairs physically — growth hormone is released, immune function is consolidated, metabolic waste is cleared from the brain. REM sleep is when emotional processing happens — experiences are integrated, memories consolidated, stress metabolised.
What Disrupts Sleep Quality
- Alcohol: Sedates quickly but fragments sleep architecture, suppressing REM significantly.
- Screen light before bed: Blue light delays melatonin by 90 minutes on average.
- Unresolved emotional stress: Anxiety activates the amygdala, preventing the deep sleep stages from completing.
- Inconsistent schedule: The body's circadian rhythm is calibrated to regularity. Irregular sleep times disrupt the entire system.
The most underappreciated factor in sleep quality is emotional state. People who process stress through conversation, exercise, or journaling consistently report better sleep quality than those who suppress or avoid it. What's unspoken during the day tends to surface at night.
