"If you have ever watched a horror movie and felt your heart racing, then you already know how fear and shock can affect our bodies. When we are surprised by a loud noise, such as the national emergency alarm, the shock can push our bodies into a highly excited state. Dr Main says: 'Our bodies react as if we are under threat.' 'Our heart rate and blood pressure spike. Cortisol, our stress hormone, surges, contributing to anxiety, irritability, and long-term stress.'"
"In our evolutionary past, that surge of activity might have helped us survive a life-or-death situation, but in the modern day, it simply takes a toll on our bodies. Dr Main's research has shown that, when exposed to emergency alarms, participants' heart rates spiked from an average of 74 to 111 beats per minute or higher. Among firefighters, the sudden shock of the emergency alarms they receive is so severe that it presents a legitimate threat to their lives."
A nationwide emergency alert test will send a loud alarm to 4G and 5G phones to deliver life-saving information during crises. Sudden alarms can activate the fight-or-flight response, causing rapid heart rate increases, blood pressure spikes, and cortisol surges that contribute to anxiety and long-term stress. Individuals with underlying cardiac vulnerabilities may face increased risk of cardiac events when exposed to abrupt alarms. Research showed participants' heart rates rose from an average of 74 to 111 beats per minute or higher. Firefighters experience such severe alarm-induced shocks that their lives can be put at legitimate risk.
