“Stress” is a common interpretation of everyday cues—such as whether someone “squeezed in a workout” before a public event. Medically, this points to normal physiologic stress reactivity rather than a disorder. Acute stress responses are mediated primarily through activation of the sympathetic–adreno–medullary (SAM) system and the hypothalamic–pituitary–adrenal (HPA) axis. The SAM pathway rapidly increases catecholamines (adrenaline and noradrenaline), producing tachycardia, mild bronchodilation, sweating, and a heightened state of alertness. The HPA axis follows more slowly: the hypothalamus releases corticotropin-releasing hormone, the pituitary secretes adrenocorticotropic hormone, and the adrenal cortex produces cortisol. Cortisol supports energy mobilization by enhancing gluconeogenesis and modulating immune function, enabling short-term adaptation.
Muscle tension is a well-recognized somatic component of stress. When a person anticipates social evaluation, time pressure, or performance demands, the nervous system can shift toward increased muscle tone and reduced parasympathetic activity. This can manifest as stiffness, a “tight” feeling, altered posture, or restlessness. From a clinical standpoint, these symptoms are typically transient, track with the stressor, and resolve when perceived demands decrease. Mechanistically, stress alters autonomic balance and can influence neuromuscular control via brainstem and spinal circuits involved in motor readiness.
Importantly, normal stress is distinct from stress-related disorders. Anxiety disorders involve persistent or excessive fear and worry, often accompanied by hyperarousal (sleep disturbance, irritability, difficulty concentrating) and somatic symptoms. In generalized anxiety disorder (GAD), worry is excessive and difficult to control, present more days than not for at least several months, and is associated with at least a subset of cognitive and physical symptoms. Post-traumatic stress disorder (PTSD) involves re-experiencing, avoidance, negative cognition/mood changes, and hyperarousal following trauma. Acute stress disorder is time-limited and follows a traumatic event. By contrast, a fleeting question about whether someone worked out before an event usually reflects a brief, nonpathologic stress appraisal.
The concept of “slay, mid, or miss” also highlights how social judgment can influence perceived stress. Social-evaluative threat activates the same general threat circuits that respond to physical danger but with different triggers. Cognitive appraisal—the interpretation of circumstances as demanding—modulates the intensity of HPA activation. People who interpret uncertainty as threatening may experience a stronger stress response, higher cortisol secretion, and more pronounced somatic tension. This is compatible with cognitive-behavioral models in which maladaptive beliefs (e.g., “I must look perfect”) increase worry and amplify autonomic arousal.
Clinically relevant thresholds include symptom duration, impairment, and physiological dysregulation. If stress-related symptoms become chronic, interfere with sleep, work, or social functioning, or coexist with panic-like episodes, clinicians evaluate for anxiety disorders, depression with anxious distress, substance/medication effects, endocrine conditions (e.g., hyperthyroidism), and sleep disorders. Red flags include suicidal ideation, severe functional decline, or symptoms suggesting medical illness (chest pain, syncope, unexplained weight loss, persistent palpitations).
Management of nonpathologic stress focuses on rebalancing autonomic tone and addressing appraisal. Evidence-based strategies include brief diaphragmatic breathing to reduce sympathetic activation, progressive muscle relaxation to counteract muscle tension, and mindfulness-based approaches to interrupt rumination. Regular aerobic activity improves stress resilience through adaptations in neurotransmitter systems and cardiovascular efficiency. Sleep hygiene reduces HPA dysregulation, as insufficient sleep increases threat sensitivity and cortisol rhythm disruption. When stress becomes persistent or meets criteria for an anxiety disorder, psychotherapy (notably cognitive-behavioral therapy) and, in selected cases, pharmacotherapy (such as SSRIs/SNRIs or short-term benzodiazepine use under careful supervision) may be appropriate.
Educational takeaway: everyday observations can prompt interest in “stress,” but medically, acute stress is a normal, adaptive neuroendocrine response governed by SAM and HPA pathways. Muscle tension is a typical somatic correlate of threat appraisal, usually resolving with reduced demand. Distinguishing normal stress from anxiety disorders relies on timing, intensity, control, associated cognition, and real-world impairment. Source: @TheManilaTimes
The Manila Times: The Manila Times Lifestyle begins this year’s SONA fashion watch with Sen. Pia Cayetano at this morning’s plenary session. Everyone knows the slim and sprightly legislator is one sporty lady, but did she actually squeeze in a workout before the opening of Congress? She appears to have tied a sweater around her waist out of habit. For “The Manila Times SONA 2026 Fashion Verdict: Slay, Mid or Miss?” this one has to be a miss. #TheManilaTimesSONA2026 #FashionVerdict #SlayMidOrMiss. #breaking
