Under stress, how does thinking typically change?

Under stress, thinking typically becomes slow and impaired due to the physiological and psychological responses triggered by stress. When a person is under pressure, the body enters a fight-or-flight mode, which can divert attention and cognitive resources away from complex decision-making and problem-solving. This impairment can manifest as difficulty concentrating, reduced critical thinking, and an increased likelihood of errors in judgment.

The brain's ability to process information effectively is compromised, leading to a sluggish thought process. This reaction is natural, as the mind prioritizes immediate survival over analytical reasoning during stressful situations. Recognizing this response is essential for divers in high-pressure environments, as it highlights the importance of maintaining calm and employing relaxation techniques to enhance cognitive function while diving.
