For exercise

You get an exercise tip every day. It tells you if you should take it easy or go for it. The tips are based on:
ANS charge gives you information on how well your autonomic nervous system
(ANS) calmed down during the night. The scale is from -10 to +10. Around zero is
your usual level. The ANS charge is formed by measuring your heart rate, heart
rate variability and breathing rate during roughly the first four hours of sleep.
A normal heart rate value for adults can range between 40 and 100 bpm. It is
common for your heart rate values to vary between nights. Mental or physical
stress, exercising late at night, illness, or alcohol can keep your heart rate up
during the early hours of your sleep. It's best to compare your last night's value to
your usual level.
Heart rate variability (HRV) refers to the variation between successive heart
beats. In general, high heart rate variability is linked to general good health, high
cardiovascular fitness and resilience to stress. It can vary greatly from person to
person, ranging from 20 to 150. It's best to compare your last night's value to your
usual level.
Breathing rate shows your average breathing rate during roughly the first four
hours of sleep. It is calculated from your beat-to-beat interval data. Your beat-to-
beat intervals shorten when you breathe in and lengthen when you breathe out.
During sleep, breathing rate slows down and varies mainly along with sleep
stages. Typical values for a healthy adult at rest range from 12 to 20 breaths per
minute. Higher values than usual may indicate a fever or impending illness.
