If you want to find out if humans are considered insulators or conductors then you’ve come to the right article.
As, in this article, you’ll find the exact answer to this question, and also after you’ve read the answer to the main question then I’ll cover the answers to closely related questions as well to further extend your knowledge.
I hope you learn a lot from this article!
Are Humans Insulators Or Conductors?
Human bodies are conductors, not insulators.
While they may not be the most efficient conductors on the planet, the skin acts as a protective barrier as human cells contain enough ions (sodium, potassium, and chloride) to carry an electrical charge.
The human nervous system constantly conducts electricity in amounts too small for us to perceive.
But if an external current touches the body, it gets transmitted to the nerves via long-tailed dendrites on our cells’ neurons.
Electricity passes through the nerves unimpeded causing a nasty shock and, in some cases, serious burns.

Is a Human Hand an Insulator Or a Conductor?
Compared with some other materials, the human hand (and its skin) is a relatively poor conductor but it’s still a conductor nonetheless.
Human cells contain a variety of natural elements (including potassium, sodium, calcium, and magnesium) which have a specific electrical charge.
These human cells, being physiologically designed to conduct small amounts of electricity, allow the charged elements (or ions) to conduct a current.
An electric shock to the hand will only cause damage if the voltage is high enough.
The outermost layer of the epidermis is slightly less conductive due to its prevalence of dead cells and slightly weaker ions.
A hand with dry skin can have as much as 100,000 ohms (resistance) compared with an internal body resistance of just 300 ohms.
However, skin is still an electrical conductor and anything more than 50 volts is sufficient to cause serious injury or even death.
Is Human Skin an Insulator or Conductor?
Human skin is a conductor of electricity though it is much less conductive than our internal organs.
The skin has a natural resistance of around 10,000 ohms which is why we can tolerate some types of low voltage electric shocks.
But the skin’s tolerance (and imperviousness to damage) depends on certain conditions.
Dry skin is a much better insulator than wet which is why touching sockets with wet fingers is considered so much more dangerous.
When moist and flexible, human skin becomes significantly more conductive.
So, it’s, for example, important to always dry your hands before touching a plug socket.
Is Human Hair An Insulator Or a Conductor?
Human hair is an insulator, not a conductor of electricity like human skin.
It is, however, also known that wet hair will conduct much better than dry hair as water is a decent conductor as well.
Why Are Humans Conductors?
Humans are conductors because so many of our basic physiological functions rely on the transmission of electrical signals to and from the brain.
If we did not conduct, we wouldn’t be able to survive.
Our muscles, for instance, contract and expand following precise electrical charges.
The cells in our body contain a multitude of elements such as sodium, potassium, chloride, and magnesium.
These naturally charged cells (or ions) are conductive and allow electricity to flow through the ionized parts of the body.
Unfortunately, human beings are only moderately conductive, so a degree of internal resistance also exists.
Together, these oppositional forces can cause serious damage if an individual receives a high voltage shock.
How Does the Human Body Conduct Electricity?
The human body is composed mostly of water which contains ionic chemicals (like, for example, sodium, chloride, and magnesium).
Pure water, with its iconic elements removed, is a relatively poor conductor.
But the water in our bodies is always mineral-rich and, therefore, much more conductive.
Electricity flows through the charged elements (or ions) in our blood and tissues.
In some circumstances, this can be dangerous and cause painful or even lethal electric shocks.
However, if the human body were not able to conduct electricity, many of its basic functions would stop.
Why Are Humans Not Insulators?
Human beings are not insulators but we’re not powerful conductors of electricity either.
Our bodies can tolerate some types of electrical charges as we must tolerate them because electrical impulses traveling to and from the brain enable many of our basic physiological functions.
So, humans are not insulators because they need to conduct electricity to survive.
We’re also not insulators because our internal organs, body tissues, and circulatory system contain large amounts of ionized water.
These ions enable the water to carry an electrical current.
Below the least conductive layer of skin (stratum corneum) the natural electrical resistivity of the body is of the order of 100 ohm-cm.
In comparison, a hyper-conductive material such as copper is around 100 million times less resistant than the human body.
So, human beings are conductors but not highly efficient conductors.
Nor are they insulators.
Is A Human A Conductor of Electricity?
A human can and does conduct electricity but only in small amounts.
The naturally occurring elements in our bodies (like, for example, sodium, potassium, calcium, and magnesium) have an electrical charge.
Our cells can use these elements (or ions) to generate and conduct small amounts of electricity.
On the inside, these cells are negatively charged.
On the outside, they are more positively charged.
When positively charged ions, cross the cell membrane, low voltage currents are generated and later converted into electrical signals which initiate movements, thoughts, and behaviors.
Is Human Hair A Conductor of Electricity?
Technically, human hair can be a conductor.
However, it is capable of conducting only an extremely weak electrical charge.
Hair is such a poor conductor that it’s often described as more of an isolator or current breaker.
Hair follicles are just not that good at conducting or resisting electricity.
The exception is when hair follicles get wet.
Wet hair loses a significant amount of electrical resistance.
It would be very unusual to sustain serious damage from an electrical current passed through damp hair but an unpleasant shock is possible.
Is A Human A Conductor of Heat?
The human body is a moderately efficient conductor of heat.
However, as with its electric conduction capacities, it’s far from the most effective heat conducting material.
While we can emit heat, we also generate it constantly and discharge a relatively small amount compared to the heat that gets stored in our blood and body tissues.
Also, the human brain must operate carefully to regulate and maintain a safe internal temperature.
Are Humans Good Conductors?
Humans are moderately efficient conductors but, compared with other materials, we do not tolerate electric currents all that effectively.
Our bodies exist in a middle ground between conductors and insulators, just resistant enough to protect us from low voltage shocks but conductive enough to allow electrical signals to travel to and from the brain.
