In emotional situations, bodily processes are triggered automatically: The heart beats faster, the pulse rises, hands become sweaty. Now what does that mean exactly?Д®xposure to fear-inducing stimuli (an angry face, the sight of a creepy spider etc.) induce emotional arousal, causing an increase in sweat secretion and, ultimately, measurable electrodermal activity. So far, so good: Emotional experiences trigger changes in autonomic arousal quite impressively. Sweat secretion and the associated changes in skin conductance are nonconscious processes that are solely under sympathetic control and reflect changes in arousal. Regulates slowly changing processes associated with вЂћresting and digestingвЂњ or вЂћfeeding and breedingвЂњ. Increased sympathetic activity is associated with bodily indicators of вЂњautonomic arousalвЂќ such as increased heart rate, blood pressure, and sweating. Represents a rapid response mobilizing system, facilitating immediate motor action (вЂњfight or flightвЂќ). Most broadly, the autonomic nervous system can be separated into the following two вЂњsubdivisionsвЂќ: Rather, it is driven and balanced by our autonomic nervous system in order to meet behavioral demands (to prepare and execute energetic movement, for example). Like other vegetative auto-regulatory processes (body temperature, heart rate, blood pressure, gut motility etc.) sweat secretion cannot be controlled consciously. While the primary purposes of sweat emission are thermoregulation and evaporative cooling, sweating on hands and feet is also triggered whenever weвЂ™re emotionally aroused. This change in skin conductance is generally termed Galvanic Skin Response (GSR). By changing the balance of positive and negative ions in the secreted fluid, electrical current flows more readily, resulting in measurable changes in skin conductance (increased skin conductance = decreased skin resistance). Whenever sweat glands are triggered and become more active, they secrete moisture through pores towards the skin surface. The density of sweat glands varies markedly across the body, being highest on the forehead and cheeks, the palms and fingers as well as on the sole of the feet. Our body has about three million sweat glands. It contains an extensive network of nerve cells that detect and relay changes in the environment based on the activity of receptors for temperature, pressure, and pain.Д¬onsistent with this complexity of function, the skin has three primary layers:Дў Dermis (cushion for the bodyВ from stress and strain)ДЈ Hypodermis (anchor to bonesВ and muscles) The skin controls body temperature by regulating sweat emission, piloerection (вЂњgoosebumpsвЂќ), and peripheral blood circulation. Together with other organs, it is responsible for bodily processes such as the immune system, thermo-regulation, and sensory-motor exploration:ДЄs a protective barrier, the skin separates our body from the environment and its threats вЂ“ mechanical impacts and pressure, variations in temperature, micro-organisms, radiation, and chemical agents. Our skin functions as the principal interface between organism and environment. To understand how GSR works, take a quick step back and have a look at the physiological characteristics of the largest organ of the human body вЂ“ the skin.

You can download your free copy below and get even more insights into the world of Galvanic Skin Response. this post is an excerpt from our Galvanic Skin Response Pocket Guide. The sweating on hands and feet is triggered by emotional stimulation: Whenever we are emotionally aroused, the GSR data shows distinctive patterns that are visible with bare eyes and that can be quantified statistically. Galvanic Skin Response originates from the autonomic activation of sweat glands in the skin. One of the most sensitive measures for emotional arousal is Galvanic Skin Response (GSR), also referred to as Electrodermal Activity (EDA) or Skin Conductance (SC). No matter whether we are stressed, nervous, fearful, psyched up, stoked, baffled, or surprised вЂ“ whenever we are emotionally aroused, the electrical conductivity of our skin subtly changes. The skin tells everything вЂ“ our skin gives away a lot of information on how we feel when weвЂ™re exposed to emotionally loaded images, videos, events, or other kinds of stimuli вЂ“ both positive and negative.
