Sleep Debt Calculator

What is Sleep Debt?

Sleep debt refers to the cumulative amount of sleep lost over a period of time due to insufficient rest compared to the recommended sleep hours. It is an important measure for understanding the gap between actual sleep and what is needed for optimal health.

Why is Sleep Debt Important?

Sleep debt affects both physical and mental health, leading to issues like fatigue, poor concentration, weakened immunity, and an increased risk of chronic conditions such as heart disease and diabetes. Tracking sleep debt can help individuals prioritize rest and take action to improve their overall well-being.

How is Sleep Debt Calculated?

Sleep debt is calculated using the following steps:

1. Total Weekly Sleep = Sum of sleep hours for each day (Monday-Sunday).
2. Recommended Weekly Sleep = Average recommended daily sleep × 7 days.
3. Sleep Debt = Recommended Weekly Sleep - Total Weekly Sleep.

Recommended Sleep Hours

The recommended daily sleep hours vary by age group:

Newborns (0–3 months): 14–17 hours
Infants (4–11 months): 12–15 hours
Toddlers (1–2 years): 11–14 hours
Preschoolers (3–5 years): 10–13 hours
School-age (6–13 years): 9–11 hours
Teenagers (14–17 years): 8–10 hours
Young Adults (18–25 years): 7–9 hours
Adults (26–64 years): 7–9 hours
Older Adults (65+ years): 7–8 hours

Example Calculation

Inputs:
  Gender: Male
  Age Group: Adults (26–64 years)
  Monday: 6 hrs
  Tuesday: 7 hrs
  Wednesday: 7 hrs
  Thursday: 6 hrs
  Friday: 5 hrs
  Saturday: 8 hrs
  Sunday: 9 hrs

Calculation:
  Total Weekly Sleep = 6 + 7 + 7 + 6 + 5 + 8 + 9 = 48 hrs
  Recommended Weekly Sleep = 8 × 7 = 56 hrs
  Sleep Debt = 56 - 48 = 8 hrs
