A Psychologist Explains: Acute Versus Chronic Stress

Stress is a natural part of life, but not all stress works the same way. Acute stress, like the rush you feel before an important meeting or while solving a sudden problem, can sharpen your focus and help you perform. Chronic stress, however, builds over time—often from ongoing pressures like work conflicts or financial worries—and can seriously impact your well-being. 

 In this article, OpenUp psychologist Britt Slief breaks down the key differences between these two types of stress and shares insights on how to manage them.

Acute Stress Versus Chronic Stress: What’s the Difference?

Stress comes in two main forms: acute stress, a short-term response that helps you tackle immediate challenges, and chronic stress, a long-term strain that can wear down your body and mind over time.

Acute stress is your body’s immediate response to a challenging or threatening situation. It’s a built-in survival mechanism, activating your “fight-or-flight” response to help you react quickly and effectively. Imagine suddenly seeing a dangerous animal on your way home. Your body instantly releases stress hormones like adrenaline, giving you the energy and focus to act fast and stay safe. It’s an essential reaction in moments of real danger.

But in everyday life, this same response can kick in during non-life-threatening situations, like being caught off guard at work. While there’s no lion in sight, the surge of stress can still leave you tense, distracted, or overwhelmed.

“Acute stress can be helpful,” explains psychologist Britt Slief. “It sharpens your focus and helps you make decisions quickly. Generally, your body is well-equipped to handle it.” This type of stress often arises from short-term challenges, like preparing for an important presentation, managing a sudden deadline, or navigating a high-pressure conversation. Once the situation passes, the stress typically subsides. Chronic stress, on the other hand, is a different story. “When stress becomes constant, it can harm your body and mind,” Britt continues. “You lose the benefits of short-term stress, and over time, it leaves you physically and emotionally drained.”

If you’re experiencing chronic stress, your stress hormones stay high and your body is in a constant state of alert. This causes physical symptoms that you’ll notice in your body, such as headaches, muscle tension, stomach aches, digestive problems, difficulties sleeping,  and reduced focus. 

 The signs your body is giving you can vary depending on the situation. Britt: explains “You might experience heart palpitations and rapid breathing one moment, and the next you could also begin to sweat and notice your muscles tense up.”
