How Much Sleep Do I Need? Build Around Your Own Pattern
Use age guidance as a starting point while paying attention to alertness, consistency, opportunity, and individual variation.

Recommendations are ranges
Population guidance is useful, but individual sleep need is not an exact universal number. Age, health, activity, pregnancy, and recovery can matter.
Give yourself a real opportunity
A consistent schedule and enough time in bed make it easier to observe whether your chosen duration supports daytime alertness.
Use daytime function as context
Regular unintended dozing or difficulty staying alert can be more important than whether a target number was reached.
Do not chase a score
A wearable estimate or calculator can support observation, but it cannot define your medical sleep need or diagnose a problem.
