About SleepCalculators.online
Welcome to SleepCalculators.online — your trusted platform for research-based, transparent sleep and wellness tools designed to help you make informed decisions about rest, recovery, and circadian health.
In an era where sleep science is rapidly advancing and digital health tools are increasingly part of daily wellness routines, we’re committed to providing calculators that combine academic rigor with practical usability. Every tool on this platform is built with one goal: to translate complex sleep research into clear, actionable insights you can trust.
Who We Are
SleepCalculators.online is developed and maintained by Shakeel Muzaffar, a digital health researcher and calculation tools specialist with a unique interdisciplinary background spanning health sciences, applied mathematics, and educational technology.
Professional Background
Shakeel brings together formal training and practical expertise across multiple domains:
- Health Sciences Foundation: DHMS (Diploma in Homoeopathic Medicine and Surgery) from the National Council for Homoeopathy, Islamabad, Pakistan
- Quantitative Analysis Expertise: Master’s degree in Economics with advanced specializations in Statistics, Advanced Mathematics, and Econometrics
- Educational Design: Master of Education (M.Ed.), focused on creating accessible learning tools
- Applied Research Experience: Independent researcher collaborating with medical professionals, sleep specialists, pulmonologists, and data scientists to develop evidence-based digital tools
This combination of health literacy, statistical rigor, and educational design principles enables the creation of calculators that are both scientifically sound and genuinely useful for everyday decision-making.
Our Approach: Research-Driven, User-Focused
Every calculator on SleepCalculators.online is built following these core principles:
1. Evidence-Based Logic
All calculations are grounded in published sleep research, clinical guidelines, and established frameworks from organizations like the American Academy of Sleep Medicine (AASM) and European Respiratory Society (ERS).
2. Transparency First
We show our work. Formulas, assumptions, and limitations are clearly documented so you understand not just the result, but how we arrived at it.
3. Context Over Numbers
Results include practical guidance and educational context. A number without understanding is just noise — we aim to empower informed decisions.
4. Responsible Scope
These tools are designed for educational and decision-support purposes. They complement — never replace — professional medical advice, diagnosis, or treatment.
5. Continuous Refinement
As sleep science evolves, so do our tools. We regularly review and update calculators based on new research and user feedback.
