Stress is an inevitable part of life. We all face varying levels of stress daily, from traffic jams to work deadlines to family obligations. However, while mild to moderate stress can be beneficial and motivate us to perform, chronic or severe stress takes a toll both mentally and physically. Understanding the impacts of stress can help us learn to manage it in healthier ways.
What Is Stress?
Before diving into the effects, it’s important to clearly understand what stress is. Stress is the body’s reaction to any change that requires an adjustment or response. The body reacts to these changes with physical, mental, and emotional responses.
Both good and bad experiences can cause stress. While many think stress only results from undesirable things, like an argument with a friend, it can also occur in supposedly enjoyable situations like planning a vacation or prepping for a fun activity. Anything that causes you to feel nervous, upset, frustrated, or anxious qualifies as a stressor.
Short-Term vs. Long-Term Stress
Stress is highly individualized, as certain scenarios affect some people more than others. Regardless of the stressor, though, the effects of stress on the mind and body can accumulate over time:
Acute stress is short-term stress that goes away quickly. This is the most common type of stress, caused by situations like having a disagreement with your spouse or getting stuck in traffic. The effects are temporary and usually pass when the event is over.
Episodic acute stress occurs when frequent acute stress starts to have a cumulative effect. This could be caused by things like ongoing conflicts at home or work or persistent money problems.
Chronic stress is stress that lasts for long periods due to major problems like trauma, grief, poverty, family dysfunction, divorce, or health concerns. The effects of chronic stress accumulate and often lead to more serious health issues.
Let’s take a closer look at how both short and long-term stress impacts mental and physical health.
Psychological Effects
Stress affects the mind in a variety of ways. While someone experiencing acute stress may have difficulty concentrating or feel temporarily worried or upset, chronic stress alters brain structure and chemistry over time:
Depression and anxiety – The hormones released when we’re stressed interrupt serotonin and other neurochemical balances in the brain that regulate mood, potentially leading to higher anxiety and increased risk for clinical depression.
Impaired brain function – MRIs on people under chronic stress often show actual shrinkage and damage to the brain’s prefrontal cortex, the area critical for memory, focus, and decision-making. This can lead to forgetfulness and difficulty thinking clearly.
Learned helplessness – Studies show animals exposed to unavoidable stress in labs will eventually stop trying to escape, even when escape becomes possible. Chronic stress leaves humans similarly helpless, zapping motivation and feelings of control.
Emotional volatility – Stress hormones and inflammation make it harder for the brain to regulate emotions. This can result in more frequent emotional outbursts, moodiness, irritability, and angry reactions to small triggers.
Addiction risk – Those lacking healthy coping skills frequently turn to alcohol, recreational drugs, gambling, and other addictive behaviors to self-medicate anxiety and other difficult emotions exacerbated by stress. However, addiction only results in more life problems and distress.
As the psychological impacts accumulate, the effects of stress cascade into further mental and behavioral issues. People suffering from high, chronic stress are at greater risk for a range of dangerous outcomes, like suicide attempts, self-harm without suicidal intent, and even psychotic breaks under extremely traumatic circumstances.
Physical Effects
In addition to impacting brain health and mental well-being, stress wreaks havoc on physical health by triggering systemic bodily inflammation. While properly regulated inflammation is a necessary part of healing, chronic inflammation causes extensive damage over time:
Digestive issues – The gut houses over 500 million neurons that directly communicate with the brain via the vagus nerve. Under stress, digestion becomes impaired, causing issues like stomach pain, ulcers, ulcerative colitis, diarrhea or constipation and IBS. Over time, poor digestion contributes to malnutrition, unexplained weight loss, and wasting.
Sleep disturbances – Stress and related gut issues disrupt the production of serotonin and melatonin, critical chemicals managing sleep cycles and mood regulation. The result can be chronic insomnia and sleep deficiency, linked to diabetes, obesity, heart disease, depression, and anxiety disorders.
Skin problems – Stress leads to issues like acne breakouts, eczema, psoriasis, and hair loss by triggering inflammation through increased cortisol. It also increases skin cell turnover.
Impaired immunity – Cortisol produced under stress hampers white blood cell production and activity for fighting illness. People under chronic stress are thus more prone to viral infections, common colds, and cold sores as well as bacterial infections like staph infections and food poisoning.
Chronic pain – Stress amplifies pain signals, worsening conditions like arthritis, migraines, tension headaches, back pain, and neuropathy. This occurs because cortisol intensifies nerve cell activity.
Heart disease – Chronic stress and inflammatory hormone release damages blood vessels and raises blood pressure, cholesterol levels, heart rate, and blood sugar posing a risk for stroke, heart attacks, and metabolic syndrome.
Accelerated aging – By shortening protective chromosomal telomeres and increasing oxidative damage linked to inflammation, stress causes rapid biological aging and the appearance of fine lines, wrinkles, and other signs of premature aging.
The cumulative effects of chronic stress ultimately dampen the entire body’s ability to regulate inflammatory response properly. This systemic loss of proper inflammatory function is called metaflammation by scientists. It underlies pathogenesis for the majority of modern diseases and disorders, including diabetes, osteoporosis, obesity, strokes, neurodegenerative disease, cardiovascular disease, asthma, autoimmune disorders like rheumatoid arthritis and multiple sclerosis, Parkinson’s disease, and even cancer.
Healthy Ways to Cope with Stress
Learning healthy ways to manage life’s inevitable stressors can minimize their psychological and physical impacts. Strategies like the following help regulate emotions and counterbalance the effects of distress on the body:
Relaxation practices – Techniques causing relaxation responses like yoga, deep breathing, massage, and mindfulness meditation help reverse damage from the flight-fight-freeze stress response.
Balanced nutrition – Eating more vegetables, fruits, and omega-3s while limiting sugar, caffeine, and alcohol stabilizes blood sugar, and supplies nutrients that regulate brain function, and combat inflammation.
Adequate sleep habits – Getting at least 7 hours per night enables memory consolidation, learning processes, and tissue repair needed to manage stress damage.
Social support networks – Sharing feelings and challenges with caring friends and family are proven buffers moderating stress hormone production and mental health impacts that isolation amplifies.
Reframing thoughts – Adopting more optimistic mindsets is linked to stress resilience as it combats hopelessness, rumination, and catastrophizing automatic reactions making pain and setbacks feel unbearable.
By learning to minimize life stressors when possible and counteract their effects through smart self-care, you can achieve emotional and physical wellness even when undergoing difficult circumstances. Support groups can also assist in recovering from more traumatic stressors like grief, job loss, or divorce by making painful challenges feel more manageable with help from others. Please speak to a doctor right away if you or a loved one shows signs of self-harm or suicidal intent, as dangerous mental health impacts from chronic stress may require medication and therapy assistance. With proper treatment, those undergoing severe life stresses can regain health, happiness, and purpose.
FAQs
What’s the difference between good and bad stress?
Good stress, sometimes called eustress, occurs in response to enjoyable occasions like promotions, holidays, and weddings. Bad stress results from negative experiences like abuse, loss, or catastrophes. While bad stress always remains damaging, good stress converts to bad stress if it occurs too long or often, depleting reserves.
Can kids experience harmful stress too?
Yes, major childhood stresses like poverty, family alcoholism, and parental loss often trigger chronic inflammatory reactions hampering learning, development, and emotional health into adulthood. Counseling and nurturing school environments help counterbalance adversity.
Is stress always outside our control?
No. While we can’t eliminate exposure to stressors like natural disasters, traffic, or bad news events, much distress results from pessimistic mindsets triggered by experiences we can manage. Learning thought pattern awareness provides opportunities to reframe automatic reactions making small annoyances feel devastating.
Can stress lead to death?
While extremely rare, stress cardiomyopathy leading to sudden fatal heart attacks has occurred in previously healthy people undergoing acute emotional distress like grief from losing a child or life savings overnight. However, more commonly stress contributes to disease and organ damage underlying mortality – like heart disease, obesity, or stroke risk – when severe or chronic.
Conclusion
Learning to minimize unnecessary stressors and counterbalance the unavoidable through smart self-care limits the psychological and physical effects of keeping you mentally sharp, emotionally resilient, and physically vital. Support groups also assist in combatting isolation exacerbating stressful situations. Seeking professional treatment right away proves critical if you or loved ones ever feel like life’s become too painful to go on as dangerous mental health impacts always deserve caring intervention.
