Research and medical expertise highlight the physiological and cognitive consequences of stress. Initial findings indicate that stress triggers the sympathetic nervous system, causing physical symptoms like increased heart rate and muscle tension, while also interfering with memory and word retrieval during high-pressure situations.

Further medical discussion by endocrinologist Megi Lekbello emphasizes the dangers of chronic stress, noting that it can disrupt cortisol production and circadian rhythms, leading to fatigue. Long-term elevated cortisol levels are also linked to the weakening of muscle mass and the erosion of bone density. 

To manage these effects, experts recommend various mitigation strategies, including controlled breathing techniques, physical activities like yoga or walking, grounding exercises, and aromatherapy.
