Why Chronic Stress Is So Harmful To Your Body — And Relationship

What Is Allostatic Load And Why Is It So Harmful?
Health And Wellness

Due to the recent pandemic, chronic stress is at an all-time high for many couples.

According to Dr. Gabor Maté, "Three factors that universally lead to stress are uncertainty, lack of information, and the loss of control."

Prolonged exposure to these stressors, generated from COVID-19 and other circumstances, can result in allostatic load.

What is the allostatic load?

This term refers to the wear and tear on the body that accumulates when we are exposed to repeated or chronic stressors. These stressors can be internal, external, or both.

According to Bruce S. McEwan, Ph.D.

"Whereas allostasis refers to the process of adaptation to challenges, ‘allostatic load’ refers to the price the body pays for being forced to adapt to adverse psychosocial or physical situations, and it represents either the presence of too much allostasis or the inefficient operation of the allostasis response systems, which must be turned on and then turned off again after the stressful situation is over."

When we experience stress or perceived threats for an extended period of time, our sympathetic nervous system — which directs our involuntary stress responses through hormones that control arousal and heart rate — gets stuck.

This cues our bodies to relax after a threat has passed and doesn’t have the chance to start. Anything that functions on overdrive without a break is susceptible to damage, including our bodies.

Long-term gradual damage is the price we pay for bodies under continual stress.

How does allostatic load impact relationships?

While allostasis has been traditionally examined in individuals, it undoubtedly impacts couples.

Historically, the consequences of allostatic load have been observed as those conditions that directly impact an individual: illness, physical strain, and hypertension.

Certainly, a link exists between the individual and interpersonal consequences.

Allostatic load can create concerns related to relationships, intimacy, and sexuality due to its positive correlation with anxiety, depression, cardiovascular disease, and other systemic disorders.

Difficulty starting and maintainting relationships.

On an interpersonal level, an increased allostatic load may result in individuals experiencing difficulty in starting or maintaining relationships.

When an individual is depressed, certain neurotransmitters aren’t functioning at an optimal level.

Even the most doting and loving partner might not be able to conjure the experience of love or limerence (infatuation or obsession with another person), typically experienced involuntarily and characterized by a strong desire for reciprocation of one's feelings.

How does allostatic load Impact secure functioning?

Dr. Stan Tatkin defines secure functioning as an interpersonal system based on principles of true mutuality, collaboration, justice, fairness, and sensitivity.

This does not mean that secure-functioning partners are without stress.

According to Dr. Stan Tatkin, "Secure-functioning partners are fully interdependent in the sense that each happily accepts the other as a burden, and both agree they are in each other’s care."

When we are the wiser and best versions of ourselves, we are able to utilize both the emotional and rational parts of our brain to inform our decisions and impact how we interact with the world around us, including our romantic partners.

However, for this to happen, we must be in our "window of tolerance." 

Stress and our "window of tolerance."

This term, coined by Dr. Dan Seigel, describes the zone of arousal in which individuals are able to receive, process, and integrate information in order to generate appropriate and effective responses.

In this current state of the pandemic, couples are less likely to be in their window of tolerance, due to concerns about the virus as well as social and economic impacts.

When an individual exits their window of tolerance, it becomes difficult for them to maintain secure functioning. And even though it may not be intentional, they often fail to maintain the empathy, alliance, fairness, and compassion that they ordinarily hold for their partner.

"Hyper-arousal" versus "hypo-arousal."

Sometimes, individuals exit their window of tolerance due to stress. When this happens, they enter into either hyper-arousal or hypo-arousal.

Hyper-arousal can be described as a "fight or flight" threat response. When an individual is in this state, they may experience anxiety, increased heart rate or blood pressure, hyper-vigilance, and racing thoughts.

In hyper-arousal, there is an absence of perceived safety.

Hypo-arousal, on the other hand, describes the freeze threat response and is characterized by sensations of emotional numbness and immobility.

Partners who enter a state of hyper-arousal may become preoccupied with racing thoughts about their stressors so much that they are unable to attune to the needs of their partner.

Conversely, partners who enter a state of hypo-arousal may become emotionally insensitive or nonresponsive.

Who Is susceptible to allostatic load?

COVID-19 has increased the majority of the population’s susceptibility to prolonged stress. While no one is immune to the impacts of allostatic load, it may be particularly heavy for specific populations.

Women, people of color, and members of the LGBTQIA+ community often carry a uniquely dense allostatic load due to the inherent systemic challenges that they face.

Women constantly face an array of challenges that contribute to the buildup of allostatic load, including overt and covert gender bias, pay inequity, sexual violence, and a lack of freedom.

In Western industrialized nations like the U.S., women are also more likely to face role strain as they are forced to balance the demands of motherhood and careers — pressure that does not tend to fall so heavily on their male counterparts.

People of color are subject to numerous injustices from the system, which may contribute to higher levels of allostatic load.

Compared to their white counterparts, racial and ethnic minorities have worse overall health, are often economically disadvantaged, more susceptible to socio-economic related stress, and more likely to face discrimination in school and the workplace.

Additionally, they may face acculturative stress — stressors associated with being an immigrant or ethnic minority and going through the process of assimilating the dominant culture.

These combined elements dramatically increase the likelihood of an individual accumulating additional allostatic load.

The LGBTQIA+ community often face societal bias, bullying, family rejection, internalized homophobia, homelessness, and workplace discrimination.

Presently, 27 states in the United States carry no explicit statewide laws at all protecting people from discrimination on the basis of sexual orientation or gender identity in employment, housing, or public accommodations.

A lack of social support paired with insecure income and a potential lack of housing opportunities add to an individual’s allostatic load.

Additionally, unique stressors mutually impact both individuals and those in relationships.

An increased stigma surrounds relationships that are not between two cisgender heterosexual individuals, including those who are in mixed-race relationships, age-gap relationships, non-monogamous relationships, and relationships of various compositions and structures.

Cis-hetero relationships are hard enough. Adding in additional elements, such as intersectional differences or multiple partners, serves to intensify relational challenges.

Anyone who is in a nontraditional relationship may face additional stress and greater allostatic load as a result of societal stigma and rejection from loved ones.

How can couples manage?

It’s important to identify and gradually lessen the allostatic load. First, recognize the many stressors that are not within your control as a couple — socioeconomic concerns and challenges experienced related to sexual orientation, race, ability.

Don't focus on the elements that you can't change, but rather on areas in which you have a sense of agency.

According to McEwan, "Two of the most important interventional approaches target physical activity and social integration."

It's no secret that a positive correlation exists among our physical well-being and mental well-being.

As a couple, participate in routine self-care practices, such as eating a balanced diet, exercising, taking medications as prescribed, engaging in pro-social communication with others, and participating in activities through which you experience flow.

When individual members of a relationship are regulated and within their window of tolerance, they are better primed for secure functioning with their partners.
