Stress has become one of the most common experiences in modern life, affecting students, workers, and families in ways that often go unnoticed. But behind the racing heartbeat and sleepless nights lies a biological chain reaction that begins deep inside the brain, and understanding it is the first step towards managing it.

For Emily Dinh, a junior at Urbana High School, stress feels as if she is “unable to understand what is happening all at once.” Between school, sports, and social expectations, she says her mind rarely gets a break. “I am constantly overwhelmed,” she exclaims.

Scientists insist that she is not far off.

According to research summarized by Harvard Health Publishing, a stressful situation, whether it’s a looming deadline or persistent worry, triggers a cascade of hormones that prepare the body to react. The amygdala sends a distress signal to the hypothalamus, which activates the sympathetic nervous system. This releases adrenaline, causing the heart to pound, breathing to quicken, and muscles to tense—the classic “fight or flight” response.

But students today aren’t running from predators. They’re running from expectations.

Adrian Kabiritsi, a junior at Tuscarora High School, believes stress among students is rising because of the pressure to plan their futures earlier than ever. “We’re expected to pick careers, focus on grades, and think about money all at the same time,” he says. “It feels like everything depends on what we do right now.”

Harvard researchers note that the body can “overreact” to these modern stressors, responding as if they were life-threatening. Over time, this repeated activation can contribute to high blood pressure, anxiety, depression, and even changes in appetite and sleep.

For Adrian, coping means stepping away from the pressure when he can. “I relieve stress by finding hobbies I enjoy and hanging out with people who take that stress away for a little,” he says. “It doesn’t fix everything, but it helps me breathe.”

For students like Emily and Adrian, understanding what’s happening inside their bodies and finding ways to interrupt the cycle may be the key to staying grounded in a world that constantly demands more.
