What You'll Learn
Electric shocks can cause serious internal damage
Electric shocks can range from mild to severe, with the severity of the injury depending on the voltage and duration of contact. Even if the shock seems minor, it is imperative to seek medical attention to rule out any internal injuries.
Internal injuries are challenging to detect and can have a lasting impact on health. For instance, serious burns can cause permanent scarring, and if the current passes through the eyes, cataracts may develop. The current may also cause ventricular fibrillation, which can lead to cardiac arrest. The risk of cardiac arrest is heightened if the current passes through the chest or head.
The heat produced by the electric current may cause severe burns, especially on unprotected flesh. The arc blast produced by vaporizing metallic components can break bones and damage internal organs. The current may also cause painful muscle spasms, severe enough to dislocate joints or break bones. The loss of muscle control can prevent an individual from releasing themselves from the electrical source, leading to prolonged exposure to the current.
Additionally, muscle damage from electric shocks can cause limbs to swell, compressing arteries and leading to serious health complications. Compartment syndrome, for example, may not be immediately noticeable but can cause significant issues if left untreated. Hence, it is crucial to seek medical attention and monitor for any signs or symptoms that develop following an electric shock.

Electricity in medicine
Electricity has been used in medicine for almost two millennia, from the use of electrical shocks from the torpedo fish to the modern implantation of neuromodulators and neuroprostheses. The human body is a complex network of electrical signals that govern everything from the way our heart beats to how our brain interprets pain.
Medtronic, a medical technology company, has been at the forefront of harnessing the power of electricity for healing. They have developed a range of medical devices, from pacemakers to neurostimulators, that tap into the body's electrical signals and make corrections. For example, their deep brain stimulation (DBS) system helps patients with neurological disorders associated with Parkinson's disease, essential tremors, dystonia, obsessive-compulsive disorder, and epilepsy.
The use of electricity in medicine has also extended to the treatment of nervous system diseases, including pain management, movement disorders, epilepsy, Tourette syndrome, psychiatric diseases, addiction, coma, urinary incontinence, infertility, respiratory paralysis, tinnitus, and blindness. Electrical stimulation techniques, such as neuromuscular electrostimulation, have been shown to be effective in treating pain and muscle wasting.
Furthermore, in vitro and in vivo studies have shown that electric and electromagnetic fields can positively impact tissue regeneration, wound healing, cancer treatment, and infection control. However, it is important to note that these fields may also have a negative impact, potentially contributing to cancer development.
Overall, electricity has proven to be a powerful tool in medicine, offering new ways to promote healing and manage debilitating diseases. With advancements in technology, the potential for electricity to revolutionise healthcare is boundless.

Electric fields may play a role in cancer development
Electricity has been used to treat a variety of medical conditions, including chronic pain and cancer. However, there is also evidence that electricity may play a role in cancer development.
Electric fields (EFs) have been shown to have a significant effect on cancer cell migration, and their role in cancer progression and metastasis is an active area of research. Endogenous EFs are naturally present in the body and play a role in directing cell migration during wound healing and development. These EFs are produced by the directional flow of charged ions through ion channels and transporters on the cell membrane. Ion channels have been implicated in breast cancer proliferation and metastasis, with certain channels promoting breast cancer cell migration and contributing to the development and progression of breast cancer.
Studies have shown that cancer growth interferes with local ionic environments, membrane potentials, and transepithelial potentials, resulting in small electrical changes in the tumor microenvironment. Fast-growing tumors produce a considerable disturbance in electric fields, while slow-growing tumors produce a similar disturbance over a longer period. These electrical disturbances can be used as a diagnostic technique for certain types of cancer.
Additionally, in vitro and in vivo studies have shown that artificial electric/electromagnetic fields may negatively impact human health and potentially play a role in cancer development. For example, one study exposed cancer cells to alternating current electric fields at different intensities and frequencies. They found that constant delivery of low-intensity, intermediate-frequency electric fields prolonged mitosis in cancer cells and induced cell death in some cases. Another study demonstrated that tumor treating fields (TTFields), which are non-invasive and portable, can slow down cancer cell proliferation by interfering with key stages of mitosis.
While the exact mechanisms are still being investigated, these findings suggest that electric fields may indeed play a role in cancer development and progression. Further research is needed to fully understand the complex interactions between electric fields and cancer cells, and to explore the potential therapeutic applications of electric fields in cancer treatment.

Electrical burns
The severity of an electrical burn depends on several factors, including the voltage and the type of current. High-voltage shocks, typically those above 500 volts, are more likely to cause serious damage, including death. Alternating current (AC), which periodically switches direction, is also more likely to cause electrical burns than direct current (DC), which flows in only one direction. AC is more commonly used in homes and offices, which may contribute to its higher incidence of electrical burns.
Internal organs, such as the heart, can be affected by electrical burns. Irregular heart rhythms or even cardiac arrest may occur. Other potential symptoms of internal damage include confusion, dizziness, headache, muscle contractions, numbness or tingling, problems with balance, and shortness of breath. Red or red-black urine may also indicate internal bleeding.
It is important to seek immediate medical attention if an electrical burn is suspected. Doctors will assess the severity of the burn and determine the appropriate course of treatment. Tests such as EKG, urinalysis, blood tests, X-rays, and CT scans may be used to diagnose the full extent of the damage, including any potential injury to internal organs.

The human body is a good conductor of electricity
The human body contains a high amount of water and various dissolved ions, allowing for low resistance. The presence of these ions decreases resistance and facilitates the flow of electric current. Ions are important when thinking of disease as they impact the flow of charge throughout the body to maintain its functionality. For example, the kidneys help to remove excess ions from the blood by excreting them via urine and osmotic pressure regulation. In general, negative ions fortify the body's immune system and enhance metabolism, whereas positive ions have the opposite effect.
The skin, specifically the epidermis, is a poor conductor of electricity, and thus has a high resistance. Dry skin can be insulating, whereas wet or blistered skin has a lower resistance. In the presence of moisture, there is less resistance and greater current. The route that electricity takes through the body is also important. The internal resistance in the body can vary between 300 to 1000 Ohms.
The human body can conduct electricity better when it is wet, as water helps salts to ionize more efficiently, further lowering resistance to electrical flow. The body's similar number of positive and negative charges also enables better electrical conduction. The human body contains large quantities of ionic solutions and fluids such as blood, sweat, and cellular fluids, which allow ions to move and conduct electricity.
