What are the impacts of thunderstorms and lightning on human health?4 answersThunderstorms and lightning can have various impacts on human health. Direct strikes and side flashes can result in cardiac and/or respiratory arrests, which can be fatal. Ground currents can cause less severe injuries, as the current does not directly pass through the brain or heart. Shock waves created by lightning strikes can also cause injuries to individuals in close proximity. Additionally, aborted connecting leaders and corona discharges can lead to thermalized electrical discharges, potentially causing harm. Thunderstorm asthma is another health impact, characterized by acute bronchospasm following a storm during pollen seasons. In terms of lightning's impact on the body, the body current and voltage, as well as the currents in the heart and brain stem, are considered. Overall, thunderstorms and lightning can have serious effects on human health, ranging from respiratory issues to cardiac and neurological injuries.
Related literature about electrical systems?3 answersOptimal placement problems of electrical devices in power systems have attracted greater attention from researchers in literature. Distributed energy resources integration into electrical grids has led to changes in electricity markets, which are becoming more complex. Functional Electrical Stimulation (FES) is a technique used for muscle activation patterns reproduction through electrical stimulation. Machine learning techniques provide productive prediction and decision-making for electrical systems using statistical data. Obsolescence management in military-based systems is a topic of concern, with areas of focus including cost optimization, life cycle management, and forecasting techniques.
Does earthing improve health outcomes?3 answersEarthing has been shown to improve health outcomes by stabilizing physiology, reducing inflammation, pain, and stress, improving blood flow, energy, and sleep, and generating greater well-being. In a study on COVID-19 patients, earthing as a preventive and treatment measure resulted in significant curing and preventive effects with a shorter illness duration. Another study found that grounding had beneficial effects on cardiovascular risk factors, such as improving the electrical charge on red blood cells and reducing RBC clumping. Consumption of alkaline-forming foods and alkaline water, along with reducing digestive-tract bacterial load, can also improve health outcomes. Earthing has been shown to reduce inflammation, blood glucose, RBC aggregation, and blood coagulation, and improve chronic pain, stress levels, heart rate variability, and immune response.
What are the long-term impacts of electrical fires on the well-being of individuals?4 answersElectrical fires have significant long-term impacts on the well-being of individuals. Survivors of electrical injuries experience worse physical health and are less likely to be employed compared to survivors of fire/flame injuries. The negative well-being effects of electrical fires include a reduction in life satisfaction, particularly in individuals residing in close proximity to the fires. The satisfaction domain most negatively affected is how safe the person feels, and individuals with low social support are more affected. Additionally, individuals with underlying morbidity and those of low socio-economic status are at greater risk of experiencing long-term effects following fires, leading to higher hospitalization rates that remain elevated for two years post-exposure. Overall, electrical fires have detrimental effects on the physical and mental well-being of individuals, emphasizing the need for preventive measures and support for affected populations.
What are the impacts of electrical fires on the well-being of individuals?5 answersElectrical fires have significant impacts on the well-being of individuals. High-voltage electrical injuries, often deadly, lead to debilitating morbidity and increased hospital stays. Fire disasters, including electrical fires, have negative effects on the mental and physical health of victims, responders, families, and communities. The 2009 Black Saturday Bushfires in Australia resulted in a significant reduction in life satisfaction for individuals residing in close proximity to the wildfires, particularly affecting their sense of safety. Additionally, the frequency of wildfire occurrence becomes the most important influence on well-being after a significant life event like a wildfire. Safeguarding electrical infrastructure against wildfires is crucial for ensuring a continuous, reliable, and resilient supply of energy.
What is the effect of heart rate variability on the human body?5 answersHeart rate variability (HRV) is a measure of the autonomic nervous system activity and reflects the balance between the sympathetic and parasympathetic nervous systems. High HRV is associated with high parasympathetic activity. HRV can be influenced by exercise training, meditation, and breathing techniques. Exposure to external radiation, such as from communication devices, can impact HRV. HRV analysis is used in medicine to assess autonomic nervous system function and has been shown to be a predictor of cardiovascular risk and mortality. Factors such as age, gender, physical activity, and body mass index can affect HRV, with age and body mass index having a negative correlation. HRV offers a non-invasive method for studying physiological and pathophysiological processes, but there are challenges in data collection and interpretation due to confounding variables. HRV has potential for evaluating autonomic nervous system changes in various physiological and pathological conditions.
