Understanding the Hypervigilance cycle

Being constantly aware of one's surroundings can be a lifesaving skill for first responders. Entering stressful and often dangerous situations requires them to protect themselves and others by quickly assessing threats and responding accordingly. This heightened awareness is developed through consistent training, recertification, and the culture within first responder communities. It is ingrained in them that a single mistake or misjudgment could mean the difference between life and death for themselves and those around them.

While this vigilance is critical for safety, it can also have long-term negative effects, particularly if first responders remain in this heightened state even when off duty. Hypervigilance, although crucial for survival, can lead to chronic stress that affects both physical and mental health. The continual strain on the body and mind can degrade their quality of life over time.

Hypervigilance is defined as "the necessary manner of viewing the world from a threat-based perspective, with a mindset that interprets unfolding events as potentially dangerous." First responders step into unknown situations with this mindset, running through mental safety protocols to stay alert. Many experienced responders shift into this mode automatically, standing in certain positions, adopting a specific stance, or keeping equipment ready without even thinking. Every scenario is treated as potentially lethal until proven otherwise.

Hypervigilance: A Biological Response
At its core, hypervigilance is a biological reaction. All living beings are wired for survival, and the brain is most attuned when it perceives a threat. It sends signals to the body to prepare for fight, flight, or freeze. This happens subconsciously and more quickly than we can recognize. During these moments, the brain triggers physical changes such as increased pulse, faster breathing, heightened temperature, and elevated blood pressure. Most people have experienced this response when startled by something, like a sudden scare in a movie. These physiological shifts enhance survival instincts like better vision, sharper hearing, quicker reactions, and a surge of energy to either confront or escape danger.

While everyone experiences this occasionally, first responders encounter it not only in dangerous situations but also deliberately activate it when entering unknown environments. This constant activation of hypervigilance has a significant impact on biological functions. Over time, repeated stress can impair both psychological and physical well-being, as the body might struggle to return to its normal state. In some cases, this prolonged stress can lead to more severe issues like post-traumatic stress disorder (PTSD). However, this article focuses on managing day-to-day hypervigilance that hasn’t escalated to PTSD.

Addressing Hypervigilance 
The challenge with addressing hypervigilance among first responders is that it can’t—and shouldn’t—be eliminated. It's essential for both personal and public safety. Training exercises can’t stop emphasizing the importance of hypervigilance, as it needs to become second nature for responders. However, the prolonged side effects of constant alertness can harm both health and relationships. First responders are trained to see threats in every situation, making it difficult to simply "turn it off" when not on duty.

Since hypervigilance is necessary, the focus should be on managing its long-term effects. First responders, their agencies, and their families must understand how hypervigilance works. One important aspect is the "lower phase" of the hypervigilance cycle, which often sets in after responders finish their shifts. During this phase, they may experience exhaustion, apathy, detachment, or isolation at home. Over time, the body may struggle to return to a balanced state and fluctuate between extremes of hyper-alertness and emotional withdrawal.

Given time, the body can naturally restore its equilibrium, but this requires allowing adequate rest and engaging with loved ones. It typically takes 18 to 24 hours for symptoms to subside, but first responders must be aware of the need for recovery. Some may find this recovery phase uncomfortable or seek the excitement they experience on the job, especially newer responders. Establishing a healthy recovery routine early in their careers is crucial to prevent negative long-term consequences, such as strained relationships and unhealthy coping mechanisms.

Dr. Kevin Gilmartin has identified several warning signs that indicate poor management of hypervigilance, including:
• A desire for social isolation at home
• Reluctance to engage in non-work-related conversations or activities
• Reduced interaction with non-work friends
• Procrastination in non-work-related decision-making
• Infidelity
• Detachment from children's needs and activities
• Loss of interest in hobbies or recreational activities

These signs suggest that the first responder is overly focused on work, neglecting other important aspects of life. Maintaining balanced interests and social circles is key to healthily managing hypervigilance.

Agencies should train first responders not only to be hypervigilant but also to return to a normal state afterward. They should ensure that responders have enough time to recover before returning to work, even though this may be challenging due to staffing constraints. Prioritizing recovery will promote long-term health and morale. This approach should be consistent throughout a responder’s career, as hypervigilance can wear them down over time.

Families and loved ones should also be educated about hypervigilance and how to support responders during their recovery time. Encouraging balanced activities and hobbies can help first responders manage stress and avoid burnout.

Tips to Manage Hypervigilance:
• Exercise: Physical activity helps relax the body and mind, countering the effects of the adrenaline rush associated with hypervigilance.
• Maintain non-work social circles: Engaging in non-work-related conversations and activities allows first responders to detach from work and reduces stress.
• Pursue hobbies and activities: Engaging in enjoyable activities can alleviate the negative effects of hypervigilance and prevent the development of cynicism that can arise from long-term service.
• Time management: Scheduling beneficial activities ahead of time and sticking to the plan, even when feeling tired, can help maintain a healthy balance.

By following these strategies, first responders can better manage the effects of hypervigilance, maintain their health, and preserve positive relationships outside of work.
