Body
Heart rate and blood oxygen from Apple Watch, read off Apple Health day charts. They only show an hourly minimum and maximum, so a match gets the range of every hour it touches. That can include minutes just before or after it. Sleep comes from the Health sleep chart (stages to about a minute).
Sleep before playing
Apple names a night after the morning it ends. Each match uses the latest night that ended before it started, so the after-midnight games on Oct 3 belong to the night before Oct 2.
