Any doctors on here please?

[atalost]

Just bought a Garmin as I never feel refreshed after sleeping.

Is this sleep graph normal please ie sp02 dropping to 87 / brpm of 8 etc?

I don’t want to hassle my GP and sound neurotic.

Thanks in advance

I’m not a GP! But asked ChatGPT -
The basics

• Sleep window: 22:01 → 06:13 = ~8h 12m in bed/asleep opportunity. That’s a solid duration for most adults.
• Sleep stages pattern: More deep sleep earlier and more REM later is a normal architecture. You do have several brief awakenings/REM/light transitions.

Restlessness & awakenings

• 30 restless moments = moderate movement/arousals. Not automatically “bad,” but it can mean your sleep was a bit fragmented (turning over, brief wake-ups, noise, temperature, stress, alcohol, late meal, etc.).
• On the chart, the big heart-rate spikes tend to line up with arousals/awake moments (common).

Heart rate recovery

• Resting Heart Rate during sleep: 49 bpm
• That’s generally a good sign of recovery/fitness if it’s normal for you.
• The black line mostly sits around the low–mid 50s with a few spikes into the 60–70s (often from brief waking, REM dreams, position changes, or disturbances).

Oxygen (SpO₂) — the standout metric

• Average SpO₂: 94% (a bit on the low side compared with the typical 95–100% range)
• Lowest SpO₂: 87% (notable dip)

Wearables can glitch (fit, motion, cold hands, sensor pressure), but if you see dips below 90% repeatedly across nights, it’s worth paying attention—especially if you also have snoring, witnessed pauses in breathing, morning headaches, dry mouth, or daytime sleepiness.

Common non-medical contributors:

• Loose watch / poor sensor contact
• Sleeping position (back sleeping)
• Nasal congestion/allergies
• Alcohol / sedatives
• Higher altitude

Breathing rate

• Avg respiration: 13 brpm = normal range.
• Lowest: 8 brpm can happen in deep sleep, but if it consistently coincides with low SpO₂, it’s another reason to watch the trend.

Body Battery

• +71 Body Battery change suggests your body registered good recovery overall despite the fragmentation.

What I’d do next (practical)

1. Check trends over 7–14 nights (one night can be noise).
2. Wear the watch snug (not tight), a finger-width above the wrist bone.
3. If low SpO₂ repeats: try side sleeping, address nasal congestion, and avoid alcohol close to bed for a few nights and compare.
4. If you repeatedly get SpO₂ < 90% or have symptoms, consider discussing with a clinician and asking about a sleep study (wearables are not diagnostic).

If you want, tell me whether this is typical for you (especially the 87% dip) and whether you snore or wake unrefreshed—I can help you interpret what pattern fits best

yesterday my fitbit decided to inform me my blood O2 was 93% which was a concern.

I have a proper finger monitor thing (bought during covid) which showed it was actually 99% (exactly where it needed to be)

Just thought id mention it. At that point my fit only had about 8% battery left. Once i recherged it my level went back to normal.

Just thought id mention

Not a doctor but I do suffer from sleep apnea. If you're not feeling refreshed after sleeping and you see variations in your SpO2 on a regular basis, I would see your GP about potential sleep apnea as the cause.

Be warned though, I was pretty rudely dismissed by mine and apparently the wait time for sleep studies on the NHS is ages. Had to go to a private ENT consultant to be diagnosed
