A biological clock calculator converts age into fascinating life statistics — heartbeats, breaths, days lived — giving perspective on human biology over a lifetime.
ସୂତ୍ର
Circadian rhythm: ~24.2 hours endogenous; entrained by light, temperature, social cues to exact 24 hours; Melatonin peaks 2–3 hours before sleep
- CBT
- Core body temperature minimum (Hours before wake time (typically 2–3 hrs))
- Melatonin
- Melatonin secretion onset (Hours before bedtime (7–9 PM typical))

- 1Average resting HR ~70 bpm → ~100,800 beats/day
- 2Average breathing ~16/min → ~23,040 breaths/day
- 3Sleep occupies ~33% of life
- 4All are statistical averages

Why do I feel tired at different times?
Circadian rhythm driven by melatonin (hormone that peaks 2–3 hours before sleep). Light suppresses melatonin; darkness triggers it. Jet lag = circadian misalignment.
How do I fix my sleep schedule?
Light exposure critical: bright light 6 AM (phase advance sleep), dim by 9 PM (allow melatonin rise). Takes 3–7 days per hour of shift. Avoid screens 1 hour before bed.
Are "night owls" real?
Mostly genetic (15–20% of population naturally later). Adolescents shift 1–2 hours later (circadian phase delay). Adults past 30 shift earlier. Shift work causes chronic circadian misalignment.
