Body Status Score

Your health in one number

Body Status is the master score of MyBodyAI: a single reading on a 0 to 100 gauge that represents your overall physiological state. Instead of checking each health index separately and trying to figure out how you're doing, Body Status gives you the answer at a glance, with the signals that decided it named underneath.

What's behind the number

Body Status has two layers. First, the state (Alert, Recovering, Steady, Strong, Peak Day) comes from a priority cascade across 11 health indices: Recovery, Immunity, Stress Load, Sleep Quality, Sleep Debt, Body Clock, Nervous System, Body Alert, Overtraining, Breathing, Cardiac Fitness, plus Morning Energy. Acute signals (body warning signals, overtraining, low morning energy) trigger Alert first; the positive ones (high recovery, balanced ANS) trigger Strong or Peak Day. The order matters: a warning always outranks a good sleep, so a great night cannot paper over an illness signal.

Second, the number within that state is a weighted blend of just four metrics that move day to day: Recovery (40 %), Stress Load (25 %), Sleep Quality (20 %) and Immunity (15 %). Each state owns a band of the gauge, and the blend places you inside it, so the number never contradicts the word next to it. Training Load is intentionally excluded; it reflects long-term volume, not today's state.

Reading your Body Status

• 88 to 98, Peak Day: everything is clicking. Recovery above 75, stress load under 35, sleep debt under an hour, and neither the illness nor the overtraining index raised. A rare state by design; it is the day for the hard session or the big meeting
• 68 to 88, Strong: several indices sit above your own recent baseline, or above fixed thresholds when there is too little history for one. Most good days land here
• 48 to 68, Steady: functioning but with clear room to optimize sleep, stress, or recovery
• 28 to 48, Recovering: your body needs attention. Recovery under 50, a sleep debt above six hours, a morning energy under 35, or overtraining building on a low battery: any one of them puts today lighter than planned
• 8 to 28, Alert: an acute signal is flagging, and one is enough: a body warning above 55, overtraining above 70, or another of the alert triggers. Time to prioritise rest and possibly consult a doctor

There is a sixth answer: no verdict. When nothing is alerting and fewer than five of the core signals are current, because the watch was off, the export is stale or the source only delivers part of the picture, Body Status says so instead of guessing at Steady or Strong; a single signal deep in the red is still a finding and is reported as one. An honest "not enough data" beats a confident number built on two signals, and the screen tells you which signals are missing so you can fix the feed.

How to use it

• Read the state, then the reasons. The word is the decision; the metrics listed under it are why. Two people on Steady can be there for opposite reasons
• It is a morning verdict. Overnight data decides most of it. The number updates as the day's data arrives, but the state rarely changes before the next night
• Let Alert change your day. Alert with a raised resting heart rate and low HRV is the pattern research describes a day or two before illness; the right response is an easy day and an early night, not a test of whether you can push through
• Do not chase Peak. Peak Day is a description of an unusually good morning, not a target. Strong every day is the healthier pattern
• Watch the week. One Recovering day after a race is the cost of the race. A week that never leaves Steady is a sleep or stress problem worth naming

Where the number comes from, for the curious

Every index behind Body Status is computed the same way: the raw signals from your wearable, scored against reference ranges, age-adjusted where the literature provides them, then shifted by where the latest reading sits against your own 30-day baseline. That is why Body Status is personal without being arbitrary, and why it does not compare you with anyone else.
