A simple four-step breathing technique used by military personnel and athletes can quickly reduce stress and anxiety by regulating the body's physiological responses.
The method, widely known as box breathing or four-count breathing, consists of four equal stages. To perform the technique, a person inhales for four seconds, holds their breath for four seconds, exhales for four seconds, and then holds their breath again for four seconds. The cycle is then repeated.
Stress and anxiety are known to negatively impact sleep quality, mental concentration, and physical health. The United States Navy SEALs, a special operations force of the US military trained to operate in extremely high-pressure environments, use this exact method to maintain focus before difficult situations.
Breathing coach Stuart Sandeman explained that while the four-second duration can be adjusted to suit the individual, all four stages of the breath must remain equal in length. He said the method helps people focus their attention and regulate how their body responds to stressful triggers.
The technique can be applied before any anxiety-inducing situation, such as an academic examination, a professional presentation, or a significant life event. While some people report feeling a noticeable difference within a few minutes, Sandeman noted that others might need to practice the breathing cycle for about 15 minutes to experience changes.
Scientific basis for stress relief
Medical research supports the effectiveness of the practice. A joint study conducted by researchers at Texas State University and the University of Toronto demonstrated that box breathing can lower a person's heart rate and reduce other physiological markers of stress.
Dr Helen Garr, a general practitioner, described the method as one of the most powerful scientifically supported techniques available for controlling the nervous system and managing the body's stress response.
Garr explained that the final phase of the cycle, holding the breath after exhaling, plays a critical role in producing the calming effect. During this specific pause, carbon dioxide levels in the body gradually increase.
The human brain constantly monitors the concentration of carbon dioxide in the blood. As these levels rise during the breath hold, the body generates a strong, natural urge to breathe. Garr said this biological response helps distract individuals from their internal thoughts, successfully shifting their attention away from anxiety and back to their physical body.
The focus on simple mental health practices follows earlier guidance from psychologists, who recently identified ten distinct warning signs indicating emotional exhaustion and a lack of adequate self-care.
