An earthquake rattled the East Coast a few days ago, shaking buildings and unsettling residents from Maryland to Maine. 

While this was the strongest in the Northeast in over a decade, there were no immediate reports of significant damage or fatalities. Experts explained that earthquakes on the East Coast may have been felt over greater distances due to the region's older, denser rocks, which transmit energy efficiently. 

Earthquakes, natural phenomena causing tremors on the Earth's surface, can affect an entire location at once. Beyond the visible destruction they cause, scientists have looked into whether earthquakes can affect the delicate balance of the human body and brain.

Understanding jishin-yoi

In Japan, there is a cultural phenomenon known as "jishin-yoi," which translates to "earthquake sickness." Locals have reported feeling dizzy, nauseous, or experiencing headaches before seismic activity. While there's anecdotal evidence, scientific studies have not definitively confirmed its existence.

The phantom earthquake sensation

Researchers have also investigated the phenomenon of "phantom" earthquakes, where a person may perceive seismic activity despite no actual occurrence. These sensations may stem from heightened anxiety or hypersensitivity to minor vibrations in the environment.

Body responses to earthquakes

During an earthquake, the body undergoes a series of physiological responses. The sudden shaking triggers the release of stress hormones like adrenaline, leading to increased heart rate and blood pressure. These responses are part of the body's innate fight-or-flight response, preparing a person to react to danger.

Impact on mental well-being

Beyond physical effects, earthquakes can also impact mental health. The fear and anxiety associated with seismic events can lead to stress-related disorders such as post-traumatic stress disorder (PTSD) or generalized anxiety disorder (GAD). Vulnerable populations, including children and the elderly, may be particularly susceptible to these psychological effects.
