About Sleep Debt

What is Sleep Debt?

Sleep debt is the cumulative effect of not getting enough sleep. It's the difference between the amount of sleep you need and the amount you actually get. Like financial debt, sleep debt accumulates over time and must be repaid to maintain optimal health and performance.

Recommended Sleep by Age

Newborn (0-3 months)14-17 hours
Infant (4-11 months)12-15 hours
Toddler (1-2 years)11-14 hours
Preschool (3-5 years)10-13 hours
School Age (6-13 years)9-11 hours
Teen (14-17 years)8-10 hours
Young Adult (18-25 years)7-9 hours
Adult (26-64 years)7-9 hours
Older Adult (65+ years)7-8 hours

Consequences of Sleep Debt

Mild (1-2 hours)
Reduced alertness, mood changes, impaired memory
Moderate (3-5 hours)
Decreased cognitive function, weakened immunity, increased stress
Severe (6-10 hours)
High risk of accidents, depression, weight gain, chronic health issues
Extreme (10+ hours)
Serious health risks, cardiovascular problems, diabetes risk

How to Recover from Sleep Debt

Gradual Recovery:
Add 1-2 extra hours of sleep per night until you feel rested. This is healthier than "binge sleeping" on weekends.
Consistent Schedule:
Go to bed and wake up at the same time every day, including weekends.
Power Naps:
Short 20-30 minute naps can help, but avoid long naps that interfere with nighttime sleep.

Important Note

While this calculator provides useful insights, it's not a substitute for professional medical advice. If you consistently struggle with sleep or suspect you have a sleep disorder, consult a healthcare provider or sleep specialist. Chronic sleep debt can lead to serious health problems including cardiovascular disease, diabetes, obesity, and mental health issues.
