Hi All, last night I had a surprising HR peak up to 130 bpm, which last for quite some minutes, see the picture in the commments area. In addition I have seen that the SpO2 was pretty flat in the low variation area. The night SpO2 was 95%, which is pretty regular for me. Checking also the sleep stages I noticed that this high bpm corresponds with an REM period. Indeed since I take glycine and magnesium threonate before sleep I have quite some vivid dreams. This can me an explanations? Somebody did have something similar?
