What does your WHOOP Recovery score mean?

What the three colors say

WHOOP's Recovery support guide calls green, 67% or above, high Recovery: its interpretation is that you are better positioned to adapt to a higher training load. Yellow, 34–66%, is moderate Recovery, when your body is maintaining baseline but may be more susceptible to fatigue or stress. Red, 33% or below, is low Recovery, suggesting increased stress and a reason to consider your recovery needs. WHOOP's developer guide lists the full bands as green 67–100%, yellow 34–66%, and red 0–33%.

Those are WHOOP's categories, not universal physiological thresholds. A 66% and a 67% fall on opposite sides of a color boundary, but that one-point difference need not represent a dramatic change in your body. Equally, a red day does not prove you are sick. Treat the color as a prompt to look closer, not as a verdict.

What WHOOP uses to calculate Recovery

According to WHOOP's Recovery support article, the score is calculated during sleep and shown in the morning. Its listed inputs include heart rate variability (HRV), resting heart rate (RHR), respiratory rate, sleep hours compared with estimated need, sleep stages and time awake, skin temperature, and blood oxygen saturation (SpO₂). The support article also says menstrual-cycle phase can be considered when applicable. WHOOP's developer documentation describes measurements from the previous day and sleep as inputs, rather than sleep duration alone.

HRV describes variation between heartbeats; RHR is your resting beats per minute. Both help WHOOP interpret how your overnight physiology differs from usual. Respiratory rate and skin temperature can provide further context when they deviate from your normal pattern. The exact calculation and weight assigned to every input are not publicly specified in these sources, so it would be misleading to treat Recovery as a simple sum or to reverse-engineer a precise percentage from your dashboard.

A good night's sleep does not guarantee a green morning. WHOOP's support FAQ explicitly notes that HRV, RHR, breathing and skin temperature can affect Recovery even when sleep looks good. Conversely, the score is not a direct readout of how much you enjoyed a night of sleep.

Your baseline matters more than someone else's score

WHOOP says it refines a personal baseline over time. Its support article specifically describes comparing current HRV with a 30-day baseline. That makes the question less 'is my HRV number high?' and more 'how does this night's reading compare with my usual pattern?' An HRV value that is ordinary for one person may be unusual for another; the Recovery percentage is an interpretation of several inputs, not your raw HRV in milliseconds.

WHOOP's developer guide says Recovery usually stays fixed during the day, unlike Strain, although editing sleep can recalculate it. That matters when comparing a morning score with how you feel after an afternoon workout: the score reflects the earlier measurement window, not a live assessment of your current state.

How to use a surprising score

Start by checking the individual measurements and your recent context. Have you slept differently, traveled, consumed alcohol, felt stressed, or changed your routine? WHOOP's support FAQ advises looking at trends rather than focusing on single-day fluctuations; it does not claim that a low score can identify which factor caused it. A persistent departure from your normal range deserves more attention than a lone color change, especially if you also feel unwell.

Use the result as one piece of wellness context alongside symptoms, perceived energy, sleep and plans for the day. It is not a personalized training prescription: neither a green score nor a red one obliges you to push or rest. WHOOP says Recovery is not a medical diagnostic tool. If you have concerning symptoms or unexplained changes, seek advice from a qualified healthcare professional instead of trying to interpret a wearable as a diagnosis.

Vybe Health is pre-launch and does not claim to reproduce WHOOP's proprietary Recovery score. If you are comparing devices and access models, our WHOOP alternative guide distinguishes WHOOP's available product from Vybe's intended approach.
