Why Is Your Sleep Quality Ruining Your Health?

Why Sleep Matters More Than You Think

Sleep deprivation increases your risk of heart disease by 48%, obesity by 55%, and depression by 300%. It is the single most important thing you can do for your health.

Understanding Sleep Cycles

Each night you cycle through 4-6 sleep cycles, each lasting roughly 90 minutes:

Stage 1: Light Sleep (5-10 min)

The transition between wakefulness and sleep. Easy to wake up.

Stage 2: Moderate Sleep (20 min)

Heart rate slows, body temperature drops. Memory consolidation begins.

Stage 3: Deep Sleep (20-40 min)

The most restorative stage. Growth hormone releases, tissue repair occurs, immune function strengthens.

REM Sleep (10-60 min)

Dreaming occurs. Critical for emotional processing, creativity, and memory.

• No screens in the bedroom

Timing

• Same bedtime and wake time every day (including weekends)
• Aim for 7-9 hours
• Last caffeine by 2pm
• Last meal 3 hours before bed

When to See a Doctor

If you consistently can't fall asleep within 30 minutes, wake frequently, or feel unrefreshed despite adequate time in bed, consult a sleep specialist. Sleep disorders like sleep apnoea are common and treatable.
