III. Workout Parameters
1. Steps
Steps, means the steps counted during walking and running.
Steps are calculated by the 3-axis acceleration sensor in the Hesvit S3. It may differ a little bit
from the actual steps.
Steps are counted from 24:00 to 24:00 the next day.
W.H.O suggests that an adult should walk 10,000 steps per day. When your steps reach an
integral multiple of 10,000, the screen will flash 10s, to congratulate you on achieving the
health requirement.
2. Mileage

16 / 23
Mileage, means the distance you've walked and run that day.
Mileage is calculated according to the walking and running steps. Meanwhile, it is related to
the individual's height (set in "my profile"). It may differ a little bit from the actual mileage.
Mileage is calculated from 24:00 to 24:00 the next day.
3. Calories burned
Exercises burned calories, only means the calories burned during exercises, not including
basal metabolism. Person daily burned calories contain consist of burned calories through
activity workout.
Basal metabolism, means the minimum energy demanded by organs to keep the body
functioning at rest. It is the energy metabolism at rest, not affected by muscular activity,
environment temperature, food and mental state. It varies by age, weight and physical fitness,
etc.

17 / 23
Exercises burned calories are calculated according to the linear relationship between speed
and calories. The speed is obtained via the calculated steps and mileage.
Calories burned are calculated from 24:00 to 24:00 the next day.
The more exercise one does, the more calories one burns. It's a sign of good health.
4.Sleep time
Sleep time, means sleep hours. Sleep contains deep sleep, light sleep and awake moments.
Hesvit S3 analyses the body activity intensity according to the data from 3-axis acceleration
sensor per minute. Based on the activity intensity, it determines the sleep state in current minute:
deep, light or awake. It further calculates the sleep start time, sleep time and awake moments
according to the sleep state per minute. When Hesvit S3 is put aside, it does not calculate the
sleep. Errors may occur in determining the sleep state, such as band sitting still, if it’s held in
one position for a long time, etc.
Sleep time is calculated from 18:00 to 18:00 the next day.
Calculated sleep time means the displayed sleep hours. It may delay 20-30 minutes, which is
normal.
Usually, the sleep time varies by age: 5-7 years: 15 hours; 8-12 years: 10 hours; 13-18 years:
9 hours; 19-59 years: 7-8 hours; above 60 years: 5.5-7 hours. Besides, the best time to sleep is
suggested from 22:00-6:00. For seniors, it's 21:00-5:00 and for children, 20:00-6:00. In addition,
people feel refreshed when their deep sleep reaches 4 hours. Otherwise, they get exhausted
easily.
IV. Physical Signs
1.Heart rate

18 / 23
Heart rate refers to the number of heartbeat per minute. Normally, it ranges from 60-100
bpm , which varies by age, gender, diet, emotion or other physiological factors and external
conditions. . In general, younger individuals have a higher heart rate than the elderly and
females have a heart rate than their male counterparts. The normal adult human heart rate is
60-100 bpm. Ideal heart rate is 55-70 bpm (athletes tend to have lower heart rates, usually 50
bpm).
Resting heart rate is the number of heartbeat per minute at total rest. It is found that the
changes in resting heart rate over time are related with the death rate due to heart disease. In
general, within the normal range, the resting heart rate is: the lower, the better. Ways to lower
the resting heart rate are to exercise and to lose weight.
Maximum heart rate is the highest heart rate an individual can achieve without severe
problems through exercise stress. Current prevailing calculation formula is: HRmax=220 –Age.
Target heart rate is the safe range for how fast your heart should beat while you exercise, to
improve the aerobic endurance level for cardiovascular system. Current prevailing calculation
formula is:
Target heart rate range=(HRmax-HRrest) x 0.6 + HRrest ~~ (HRmax-HRrest) x 0.8 + HRrest.
For example, a man ages 22 with HRrest of 68, his target heart rate range is:
((220-22)-68)x0.60+68=146~~((220-22)-68)x0.80+68=172, that is, 146~~172.
Normally, heart rate increases immediately after exercise and decreases at a fast rate after
exercising stopped, that is, heart rate recovery time is quite short. --------->(If occurrence of a
slow heart rate increases and decreases, please see your physician
Heart rate is obtained by measuring the pulse. With the photoelectric reflection sensor, it
obtains the wrist blood pulse signal. The blood pulse is consistent with the heart rate.
To measure the heart rate accurately, wear the Hesvit S3 tightly around a bare wrist about
2cm above the wrist joint. Heart rate test may fail in the following situations: 1) Improper
wearing of the Hesvit S3; 2) Too large space between the Hesvit S3 and your wrist; 3) Too large
amplitude of the arm swings, e.g., during running or walking.

19 / 23
Heart rate tests automatically on the hour, such as 1:00, 2:00, etc. Total 24 times a day. Or,
press and hold ♥ button for more than 2s until "--" besides "♥" flashes. Release the button. It
starts to test heart rate.
When heart rate exceeds 100bpm, the screen will flash for 10 sec as an indication of high
heart rate warning.
2. Wrist skin temperature
Wrist skin temperature means the temperature on wrist skin. Body temperature varies on
different parts of the body and from person to person and even at different time of the day.
Wrist skin temperature is measured by the temperature sensor. Temperature sensor is usually
a resistive sensor. The resistance changes with the wrist skin temperature. Ideal resistance
changes linearly with the temperature. This linear relationship is used to analyze the wrist skin
temperature.
Same as the heart rate, the wrist skin temperature tests and saves automatically on the hour,
such as 1:00, 2:00, etc. Total 24 times a day. Or, press and hold ♥ button for more than 2s until
"--" besides "♥" flashes. Release the button. It starts to test and save.
Temperature varies on different parts of the body. Head temperature is generally higher than
foot temperature. Take forearm for example. Normally, forearm temperature is 1℃lower than
axillary temperature. Body temperature can thus be inferred. It is found in a comfortable
environment, the average skin temperature is 33.8℃, with a mean deviation of 0.6℃.To
maintain a comfortable average skin temperature is an important condition to ensure human
thermal comfort.
V. Environment Parameters
1. Wrist humidity

20 / 23
Wrist humidity means the humidity of the air between wrist and Hesvit S3. It is different
from environment humidity, and is affected by both wrist skin humidity and environment
humidity.
Wrist humidity is obtained according to the change of the electrical signal, which is
converted from the amount of humidity by the temperature & humidity sensor.
Wrist humidity is tested automatically on the hour, such as 1:00, 2:00. With a total of 24
times a day.
At a given temperature in a given volume, the less water vapors present in the air, the drier
the air is. On the contrary, the more water vapors in the air, the moister the air is. Most
comfortable humidity is 50%-70%.
When wrist humidity becomes extremely high, e.g., 80%-95%, it indicates the user is
sweating. When wrist humidity is too low, the skin becomes dry, rough, peeling, which
indicates the water content of the cuticle is dropping.
According to the changes of wrist humidity, users can find out the nursing method suitable
for themselves, like strengthening the skin care, adjusting the structure of diets and drinking
more water.
2. Wrist temperature
Wrist temperature means the temperature of the air between wrist and Hesvit S3. It is
