After falling asleep to a mindfulness session (used as intended at night), it awaits me ending the session upon waking up in the morning. So the heart rate difference is recorded at the start of the session but then its mentioned that the session was completed over eg. 7hours instead of the 30minute duration of the session. The heart rate difference is therefore not a true reflection of the session as it can show as an increase upon waking / getting out of bed. That's not useful.
