Skin temperature in general
The temperature at the surface of the skin changes according to blood circulation
through body tissue. The small blood vessels (arterioles) crossing through the tissue
are surrounded by fibers of smooth muscle, which are controlled by the sympathetic
nervous system.
In a state of increased exertion, excitement and stress, these muscle fibers contract,
causing a stenosis of vasculature. This leads to a reduction of skin temperature, since
blood circulation through the tissue is reduced. In contrast, in a state of relaxation, the
musculature is also bound to relax, causing the vasculature to expand. Hence, the skin
temperature rises.
Mental stress often leads to a lower peripheral perfusion and a decrease of skin
temperature at the hands, caused by increased activity of the sympathetic nervous
system. This has a sense of evolution because tension and anxiety originally served
the preparation for an impending flight or an attack. As a result, as much blood as
possible is available in the working muscles (upper arms, thighs and torso), which is
achieved by the narrowing of vessels in the hands, feet and forearms.
For example, think of a speech that you gave in front of an audience or a job interview
panel. If you were anxious in those situations, can you remember having cold (and
sweaty) hands?
This physiological stress reaction can be useless or even harmful in many contexts in
modern society (e. g. mental exertion, worries, psychosocial stress, and anxiety
disorder). A conscious control of physiological stress can help you react in a more
relaxed and efficient manner to many situations. Biofeedback is an established way to
learn this kind of control!

Skin temperature and biofeedback training
To reduce stress and its vegetative symptoms, biofeedback-training can be conducted
by striving for a rise of the skin temperature.
Biofeedback with skin temperature is mainly applied in relaxation exercises. It’s easy
to handle and learn. Experience with this technique shows a high rate of success and
improvement of subjective well-being. In the therapeutic field, skin temperature
biofeedback is often used in migraine and chronic pain. If you suffer from a serious
disorder or medical condition, always consult a professional physician or therapist, and
do not attempt to treat yourself. Biofeedback training is not an officially recognized
medical procedure. Hence the eSense Temperature is not a medical device and may
only be used for stress reduction training.
A particularly easy and effective biofeedback method is hand warming training. It works
with the eSense Temperature sensor attached to a finger, or simply held between the
thumb and index fingers. You will learn through direct feedback to intentionally raise
the temperature of your fingers, thus increasingperfusion in your hands. The biological
temperature sensors in our hands give us only an inaccurate impression of our skin
temperature. We can just roughly decide between warm, cool, cold and so on. The
real-time feedback with the precise eSense Sensor will give you much more precise
information on the perfusion and temperature of your hands, enabling you to learn
conscious control of these parameters and your relaxed well-being.

Hand warming training aims to show a person their skin temperature and help them
get direct control over the blood circulation in their outer limbs.
Biofeedback training consists of four training stages. For the first training, schedule
about 60 to 90 minutes of free time in which you can conduct the training undisturbed
and at a stretch.
It must also be differentiated between different types of stress. There is “bad stress,”
distress, and there is “good stress,”eustress. You need to ask yourself if you are
stressed because you feel overwhelmed and are angry about something or because
you are upset. Or are you “stressed”because you are full of drive and are excited? In
both cases, the eSense Skin Response shows elevated values, but in the first case
only, this is to be judged negatively. In the second case, you can simply enjoy and use
the active or euphoric state.

Process of training
1. To train successfully, find a quiet room with a temperature of 20-22°C / 68-72
°F and where there are no phones and sources of distraction. Make sure the
room has convenient seating and that you are wearing comfortable clothing. As
skin temperature depends also on ambient temperature, you should try to
perform each training session under similar ambient conditions.
Use the accompanying tape (or a fabric tape of your choice, e.g. Leukoplast™)
to attach the temperature sensor to your index or middle finger. Plastic tape
works as well, although it’s less comfortable because it’s airtight and can make
your fingers perspire.

2. You should get accustomed to the ambient temperature for at least five minutes
(acclimatization), letting the training start while your body is in a relaxed and
constant state. This phase of acclimatization can already raise your hand
temperature by several degrees.
First stage (observe and experiment; determine your initial status)
1. In comparison with other biofeedback techniques, you will need fewer sessions
for a reliable success. 6-10 sessions should be sufficient. To keep focused
throughout the entire session, you should limit each session’s length to about
9
30 minutes. If you start feeling tired while training, you should shorten your
sessions and practice more often instead.
2. You should record your baseline state for 2-3 minutes at the beginning of each
session, letting the sensor temperature adapt to your finger. Sit upright and
comfortable, and do NOT watch the temperature but simply let the device
measure. The temperature should reach a constant level for the actual training
to begin.
3. In your first session, take ten minutes and try to relax. How you do this is up to
your personal preferences and possibilities. Do NOT watch the temperature in
the app! Training is about measuring whether relaxation already leads to a
higher temperature in yourself.
4. Now look at the measured values and whether you have already caused an
increase in temperature by relaxing. Were there sections of rising values? Did
the level remain constant? Or does the curve drop slowly during the
measurement? How do you rate your ability to relax during the measurement?
You may already be able to determine a relationship between the curve and
the tension or relaxation you are feeling. Regardless of whether you've
succeeded, familiarize yourself with the feedback in the app. Observe the
measured values and test whether you are able to influence the temperature
at will. After that, the first training phase is over.

5. This is your initial training state. Of course, the day also plays a role here; it
may make a difference whether you are measuring after a stressful working
day (or even at work) or at the end of a relaxing weekend. Use the
corresponding function of the app to export this baseline as a CSV file.
You can do this by selecting the measurement in the archive. This will
allow you to access your baseline later (in addition to the archive) by
other tools (such as Excel).
