It is a sleep signal
Apple says Apple Watch can help track your breathing rate as you sleep, and the Sleep entry shows the range of your respiratory rate while asleep.

How to read Apple Watch respiratory rate during sleep
Apple Watch sleeping respiratory rate is easier to understand when you connect the overnight range, Sleep tracking setup, Vitals, your usual baseline, symptoms, illness, alcohol, travel, room conditions, and the fact that respiratory rate measurements are not intended for medical use.

Quick rule
Baseline before alarm
Check whether Sleep tracking is on and whether the watch had enough battery and skin contact overnight.
Compare sleeping respiratory rate with your usual range, sleep duration, resting heart rate, HRV, Vitals, illness, alcohol, travel, and room conditions.
Do not confuse respiratory rate with Apple Watch sleep apnea breathing disturbances or a sleep apnea diagnosis.
Look for repeated changes and symptoms before reacting to one overnight reading.
If you have breathing symptoms, chest pain, severe shortness of breath, or a result that worries you, seek medical care.
Vitals adds baseline context
Apple says the Vitals app can show overnight metrics like heart rate, respiratory rate, wrist temperature, blood oxygen where available, and sleep duration.
It is not a medical answer
Apple says respiratory rate measurements are not intended for medical use, so the useful move is context, repetition, symptoms, and clinician review when needed.
Do not treat respiratory rate as a diagnosis
Apple says respiratory rate measurements are not intended for medical use. A single higher or lower night should not become a diagnosis, treatment plan, sleep apnea conclusion, or reason to ignore symptoms.
Connect respiratory rate with the rest of your data
LongevityMate is built around joining wearable context, sleep, recovery, Vitals, blood work, goals, progress history, and Mate follow-up questions so one overnight metric does not become the whole plan.
Also checking sleep apnea notifications?
Apple Watch respiratory rate is not the same signal as sleep apnea breathing disturbances. Read both with their own limits before turning a sleep metric into a conclusion.
Source context used for this guide
Apple support describes Sleep tracking, sleeping respiratory rate, Vitals metrics, typical ranges, Vitals notifications, sleep apnea notifications, watch fit, and medical-use limits. Use those details as prompts for safer questions, not as care instructions.
