Workflow
Calculate Optimal Sleep Schedule
15 minutesUse 90-minute sleep cycles to find ideal bedtimes that align with your required wake time for refreshed mornings.
Review Metabolic Baseline
20 minutesCalculate BMR and daily calorie needs — poor sleep disrupts hunger hormones and increases calorie requirements for recovery.
Optimize Sleep Environment
1-2 hours setupSet room temperature (16–19°C / 60–67°F), eliminate light sources, and establish a wind-down routine 30–60 minutes before bed.
Track Improvements and Adjust
Ongoing — 10 min/weekMonitor sleep quality weekly, adjust bedtime based on sleep calculator cycles, and correlate with energy and calorie intake.

Sleep Duration Recommendations by AgeTable
National Sleep Foundation guidelines for optimal sleep duration.
| Age Group | Recommended Hours | May Be Appropriate |
|---|---|---|
| Adults (18–64) | 7–9 hours | 6–10 hours |
| Older Adults (65+) | 7–8 hours | 5–9 hours |
| Teenagers (14–17) | 8–10 hours | 7–11 hours |
Sleep Cycle StructureFormula
Each 90-minute cycle includes light sleep, deep sleep, and REM. Completing full cycles prevents grogginess.
Sleep Hygiene ChecklistTip
Key environmental factors: temperature 16–19°C, darkness, quiet (<30 dB), no caffeine after 2 PM, no alcohol within 3 hours of bed.
Morning Light Exposure
Get 10–30 minutes of outdoor light within an hour of waking to anchor your circadian rhythm.
Limit Naps to 20 Minutes
Long naps or naps after 3 PM disrupt nighttime sleep pressure and delay sleep onset.
Exercise Helps, But Time It Right
Regular exercise improves sleep quality, but vigorous workouts within 2 hours of bedtime can delay sleep onset.
Use Sleep Restriction Sparingly
Temporarily limiting time in bed can consolidate sleep for chronic insomniacs — but only under guidance, not as a first step.
Safety Notes
- Persistent insomnia lasting more than 3 weeks, loud snoring with gasping, or excessive daytime sleepiness may indicate sleep apnea — consult a sleep specialist.
- Do not combine sleep supplements (melatonin, valerian) with prescription sedatives without medical guidance.
