ANS charge details in the Flow app

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.

For sleep

If you didn't sleep as well as usual, you get a sleep tip. It tells you how to improve the aspects of your sleep that weren't as
good as usual. Besides parameters we measure from your sleep, we take into account:
sleep rhythm over a longer period of time
l
Cardio load status
l
exercise on the previous day

For regulating energy levels

If your ANS charge status or sleep charge is particularly low, you get a tip that helps you get through the days with a lower
recharge. They are practical tips on how to calm down when you're in overdrive, and how to energize when you need a
boost.
