Medical Disclaimer

MySleepCycles.com provides educational information and general guidance only. Nothing on this site is intended to be a substitute for professional medical advice, diagnosis, or treatment.

Always seek the advice of your GP, physician, or other qualified health provider with any questions you may have regarding a medical condition or sleep disorder. Never disregard professional medical advice or delay in seeking it because of something you have read on this website.

Who This Site Is Not For

The calculators and information provided on MySleepCycles.com are designed for general audiences seeking to optimise healthy sleep habits. This site is not appropriate for:

• Individuals with diagnosed sleep disorders (such as sleep apnoea, narcolepsy, REM behaviour disorder, or severe chronic insomnia).
• Individuals experiencing symptoms that may require clinical attention (e.g., chronic exhaustion despite adequate sleep, loud snoring with witnessed breathing pauses, or falling asleep uncontrollably during the day).
• Children under the age of 13 without adult supervision, as their sleep needs and patterns differ significantly from adults.

When to See a Doctor

You should consult a healthcare professional if you experience any of the following "red flag" symptoms:

• Persistent difficulty falling asleep or staying asleep.
• Waking up gasping or choking for air.
• Loud, disruptive snoring often accompanied by pauses in breathing (witnessed by a partner).
• Excessive daytime sleepiness that interferes with your ability to function, work, or drive safely.
• Unusual behaviours during sleep, such as sleepwalking or acting out dreams.
• Persistent morning headaches or waking up feeling unrefreshed despite sleeping for 7-9 hours.

Calculator Limitations

Our sleep tools are built on generalised, population-average models (such as the 90-minute sleep cycle model and National Sleep Foundation duration guidelines). While these are useful heuristics for many people, they have inherent limitations:

• They cannot account for your unique individual physiology, genetics, or specific sleep architecture.
• They do not factor in underlying medical conditions, mental health status, or the effects of prescription medications.
• They are estimates and should be used as a starting point for developing better sleep habits, not as rigid medical prescriptions.

No Endorsement

MySleepCycles.com does not recommend or endorse any specific medical treatments, supplements, medications, mattresses, sleep tracking devices, or procedures. Any mention of such interventions in our educational content is for informational purposes only.

International Note

Sleep duration recommendations and clinical guidelines can differ slightly between national health bodies (such as the NHS in the UK and the National Sleep Foundation or American Academy of Sleep Medicine in the US). We aim to provide consensus-based information that aligns broadly with these major institutions, but regional variations exist.
