You Don't Need 8 Hours of Sleep...

Key wellness strategies / self-care takeaways

• Stop treating sleep as a fixed “8-hour block.” Feeling bad in the morning can happen even when you get 8 hours—because sleep is cyclical.
• Use sleep cycles to time waking up. A typical sleep cycle is ~90 minutes, moving through stages like light sleep → deep sleep → REM, then back to light sleep.
• Avoid waking during deep sleep. If your alarm interrupts a cycle—especially during deep sleep—you can experience sleep inertia (grogginess/brain fog) that can last for hours.
• Aim to wake at the end of a 90-minute cycle. This makes it much easier to wake up alert and energized.

Practical method (bullet steps)

• Plan your total sleep time in multiples of 90 minutes, such as:
  • 5 cycles = 7.5 hours
  • 4 cycles = 6 hours (sometimes can feel better than longer sleep that’s interrupted)
• Count backward in 90-minute blocks from your wake time.
  • Example: If you need to wake at 7:00 a.m.
    • Wake timing for 5 cycles (7.5 hours) means target sleep onset around 11:30 p.m.
    • Add ~15 minutes to fall asleep → lights out ~11:15 p.m.
• Prioritize sleep timing over sleep duration.
  • “How you sleep matters way more than how long you sleep.”
