What makes stress harmful?
According to Alyssa Epel, stress is not simply the presence of a difficult event. It becomes costly when the body remains vigilant, the mind keeps rehearsing threat, and recovery does not occur. Someone may even fail to notice stress while carrying tension and staying physiologically activated through the day.
A short stress-response checklist
- NoticeCheck for physical tension, such as clenched hands, even when you do not consciously feel stressed.
- ClassifyAsk whether the situation is an acute challenge, a demand requiring daily restoration, or a chronic condition that cannot be changed.
- ChooseUse effort where action is productive, and practice release where continued problem-solving only repeats the same struggle.
- RecoverLook for ways to restore after activation, including movement, calming surroundings, slower breathing or a more coherent personal narrative.
Can stress ever be useful?
Yes, when it is manageable, interpreted as a challenge and followed by recovery. Epel describes repeated moderate stress as potentially building stress resilience, while challenge-oriented thoughts can support better performance and faster recovery than a response dominated by threat.
The key is not eliminating stress, but matching the response to the situation
The strongest practical lesson in this discussion is a rule of discrimination: engage when effort can improve the situation, and let go when continued struggle cannot. Epel describes stress as the feeling that demands exceed resources, but emphasizes that the stressor itself is only part of the story. The body mounts a response, and harm depends in part on whether that response resolves or remains active through thought and vigilance.
That distinction avoids two misleading goals. Trying to remove every challenge would also remove opportunities for purpose, growth and engagement. Treating every difficulty as a battle, however, can keep the nervous system mobilized long after useful action has ended. The relevant question is therefore not whether a person feels stress, but whether the response fits what can actually be changed.
First, notice the stress that has become ordinary
People often recognize a dramatic crisis but miss the lower-level activation that accumulates during ordinary life. Epel points to clenched hands and bodily tension as clues that stress may be present even when someone does not report feeling stressed. The body can remain vigilant and scan for danger while the mind treats that state as normal.
Overthinking adds another layer. The mind tends to move toward perceived threat and problem-solve it, but that process can become an all-day red state rather than a solution. Epel groups possible responses into awareness and reframing, body-based strategies that work stress through, and changing the environment by adding safety signals such as comforting music, smells, pictures or pets.
Use challenge when the stressor can train capability
The interview distinguishes a threat response from a challenge response. Two people may face the same event and show increased blood pressure, yet one may interpret it as evidence of danger while the other thinks, in effect, that the task is difficult but manageable. Epel says these interpretations are associated with different cardiovascular patterns, problem-solving capacity and recovery.
This does not mean positive thinking can erase every stressor. Epel says the useful statements are the ones a person actually believes, such as “I have what it takes” or “I can get through it.” In the studies she describes, reframing stress as potentially helpful was associated with better performance, more positive emotion, improved problem solving and quicker recovery in stressful situations.
When control is unavailable, acceptance protects attention
Chronic stress is different from a short event because the underlying situation may continue for years. Epel uses caregiving as an example of a demand that cannot always be removed or solved. In those circumstances, repeatedly wishing reality were different can maintain the stress state, while radical acceptance offers a way to acknowledge the situation without allowing it to occupy every part of the mind.
Her “drop the rope” metaphor makes the tradeoff concrete. Pulling against a brick wall may express care and determination, but if the wall cannot move, the effort mainly consumes the person pulling. Releasing that struggle does not remove the wall. It frees resources for the areas where the person still has control, and Epel describes acceptance as a repeated practice rather than a one-time decision.
Build a flexible toolkit for recovery and uncertainty
The source supports a varied toolkit rather than a single universal technique. Physical activity can work stress through the body, while a calmer setting can reduce exposure to triggers. For uncertainty, Epel describes shifting from an alert, forward-leaning posture toward slower breathing, receptivity and curiosity. These practices change the mode of responding, especially when prediction and control are impossible.
Narrative is another part of the toolkit. Epel argues that creating a coherent account of experience can help people find meaning, resolution and a sense of purpose. Taken together, the discussion suggests a practical sequence: notice the body, identify what is controllable, choose effort when it is useful, and create enough recovery and meaning that a difficult day does not become a permanent state of threat.
