Estimate lifestyle health damage from daily habits
The Health Damage Calculator converts everyday habits into a simple health pressure score. It looks at sleep, junk food, screen time, sitting and exercise together.
It is not medical advice, but it helps users notice the habits that are most likely to hurt future energy and wellbeing.
What this tool shows
- Sleep gap is treated as a high-impact risk.
- Junk food days and sitting hours add pressure.
- Exercise creates a protective offset.
- Screen time reflects recovery and attention load.
- Scenarios show the benefit of sleep and exercise improvements.
How to use the result
Change one input at a time and compare the scenario rows. The calculator is most useful when you test your current reality, a better habit case and a strict improvement case.
Frequently asked questions
Is this a medical calculator?
No. It is an educational habit-risk calculator.
What habit affects the score most?
Sleep and exercise usually have the biggest practical effect.
Does junk food once a week matter?
Small amounts may be manageable; repeated weekly frequency creates pressure.
Can exercise cancel all damage?
No. Exercise helps, but sleep and nutrition still matter.
How should I act on the result?

Are these results exact predictions?
