Static electricity generated by the human body can disrupt normal surface electrical potentials, affecting cardiac electrophysiology and unimpeded ECG conduction. This static charge may exacerbate medical conditions or trigger premature beats. Prolonged exposure can also increase blood alkalinity, reducing serum calcium levels and increasing calcium excretion. This leads to skin itching, hyperpigmentation, physiological imbalance, and emotional disturbances.
Many computer workers experience facial conditions like erythema and hyperpigmentation. This is caused by static electricity from computer screens attracting large amounts of airborne dust, which irritates the skin. Additionally, elderly individuals are more susceptible to static electricity hazards due to relatively drier skin compared to younger people, coupled with cardiovascular system aging and reduced resistance to interference, potentially triggering cardiovascular diseases.
During winter, excessively dry air can generate static electricity between the skin and clothing, with peak voltages reaching tens of thousands of volts, causing physical discomfort.Studies and measurements of everyday static electricity reveal that walking on carpet can generate 1,500 to 35,000 volts, while walking on vinyl flooring produces 250 to 12,000 volts. Simply shifting weight on a chair indoors can create over 1,800 volts. Static intensity primarily depends on ambient humidity.Generally, static interference exceeding 7,000 volts causes a noticeable electric shock sensation. Relevant data indicates that static electricity poses significant health risks to humans. Prolonged exposure can elevate blood alkalinity, reduce serum calcium levels, and increase urinary calcium excretion. This is particularly detrimental for growing children, elderly individuals with low blood calcium levels, and pregnant or lactating women who require substantial calcium intake.Excessive static electricity accumulation in the body can also cause abnormal electrical conduction in brain nerve cell membranes, affecting the central nervous system. This leads to changes in blood pH and oxygen characteristics, disrupting physiological balance and causing symptoms such as dizziness, headaches, irritability, insomnia, loss of appetite, and mental confusion.Static electricity can also disrupt blood circulation, the immune system, and the nervous system, affecting the normal functioning of organs (especially the heart). This may lead to abnormal heart rhythms and premature heartbeats. During winter, approximately one-third of cardiovascular incidents are associated with static electricity. In flammable or explosive environments, static electricity on the human body can even trigger fires.
