Introduction
Stress is the emotional strain or tension experienced by an individual due to a reaction toward various demanding and influential situations. The challenging or compelling situations are termed stressors. Stressors can be internal or external and include life changes such as losing a significant figure, low socioeconomic status, relationship problems, occupational challenges, and familial or environmental factors. An individual’s response to stressors influences the outcome of their life. Health is a state of complete social, emotional, and physical well-being and not merely the absence of disease. Stress is a common risk factor for negative health status secondary to negative adaptation and coping with the stressors. Stressors can create a strain on one’s physical, psychological and behavioral well-being, leading to lasting effects that are detrimental to one’s health.
Physical Effects
Stress is associated with various physical health impacts on an individual. In an online cross-sectional survey by Keech et al. (2020) to determine the association between stress and the physical and psychological health of police officers, the findings illustrate that stress negatively impacts physical and psychological well-being. One hundred and thirty-four police officers were involved in the study (Keech et al., 2020). The findings demonstrate that stress resulted in various short and long-term physical effects that included increased heart rates, sweating, high blood pressure, and long-term development of the cardiac condition. In addition, stress resulted in the development of gastrointestinal disorders such as peptic ulcer and irritable bowel syndrome. Keech et al. (2020) note that stress’s associated physical health effects are explained by various mechanisms that include overstimulation of the sympathetic nervous system and the hypothalamic-pituitary-adrenocortical axis.
Overstimulation of the sympathetic nervous system results in increased sympathetic actions on the peripheral body organs leading to increased sweat production, heart rate, respiration rate, and urinary and bowel elimination. The study notes that chronic stress without positive adaptation measures results in the progressive development of hypertension, peptic ulcers, and irritable bowel syndrome as long-term effects (Keech et al., 2020). Within the gastrointestinal tract, chronic stress activity on the sympathetic nervous system results in increased parietal cell action. Overactivity of the parietal cells results in excessive gastric acid production, gradually eroding the mucosa, and ulceration occurs.
The effects of stress on the cardiovascular system are explained in a review by Kivimäki & Steptoe (2017) to determine the impact of stress on the development and progression of cardiovascular diseases. In the review, stress is identified to cause cardiovascular conditions secondary to the effects of sustained sympathetic action on heart contractility and peripheral vascular resistance (Kivimäki & Steptoe, 2017). The sympathetic nervous system contributes to normal heart and blood vessel contractility. However, when the system is overstimulated, a surge in contractility above the normal limits ensues, leading to the progressive development of heart conditions.
Psychological Effects
Psychological well-being incorporates a positive mental health status evidenced by an individual’s satisfaction with life, happiness, rational thinking and decision-making, and positive mood patterns. Stress has been associated with alterations in an individual’s psychological wellness. An explanation for alteration in an individual’s psychological well-being secondary to stress is negative adaptation. Keech et al. (2020) note that an individual’s response to a stressor determines whether stress results in positive or negative effects. In the online cross-sectional survey by Keech et al. (2020), the findings illustrate that pressure resulted in the development of anxiety, depression, and bipolar disorders as long-term effects among the participants. Exposure to stressful situations resulted in progressively developing anxiety among the individual secondary to persistent worry over the issue. The anxiety results in other physical manifestations, including increased heart rate, palpitations, sweating, and altered mobility. Depression and bipolar conditions were also associated with chronic stress secondary to the impacts of stress on neurotransmitter function and nerves.
Similar findings are noted in a cross-sectional study by Zhang et al. (2020) to compare the prevalence and severity of stress-associated mental health symptoms, including anxiety, depression, and insomnia among healthcare workers during the COVID pandemic. Five hundred and twenty-four healthcare workers were involved in the study. The study findings illustrate that 31.3% of the participants developed depression secondary to the stressful working environment, 41.2% reported anxiety, and 39.3% reported sleep disturbances (Zhang et al., 2020). The scientific explanation for the relationship between stress and depression was attributed to the effects of stressful periods on neurotransmitter homeostasis. Chronic stress results in the altered regulation of neurotransmitters in the central nervous system. Alterations in serotonin, norepinephrine, and dopamine resulted in the progressive development of depression and anxiety. Sleep disturbances reported by the participants are attributed to alterations in cortisol hormone homeostasis secondary to overstimulation of the hypothalamic-pituitary-adrenocortical axis.
Behavioral Effects
Stressful situations can also lead to alterations in the behavioral patterns of an individual. The most common behavioral effects secondary to stress include the development of eating disorders, altered sleeping patterns, impaired concentration, and drug abuse especially alcohol. Alterations in sleep and eating patterns are linked to stress’s effects on the hypothalamic-pituitary-adrenocortical axis (HPA). Exposure to stressful events leads to increased activation of the HPA axis with a net effect of increased catecholamine production (adrenaline and noradrenaline) (Moustafa et al., 2018). Increased adrenaline and noradrenaline production results in dysregulation in the eating and sleeping patterns. Sustained high levels of cortisol results in difficulty falling asleep and increased metabolic processes. The biological clock regulates the typical sleeping pattern that relies on producing the sleep hormone melatonin. Melatonin production by the pineal gland is regulated indirectly by the concentration of serum cortisol levels and directly by light perception. Imbalances in the serum concentration cycle secondary to stress results in imbalanced melatonin production and concentration with a net effect of sleeping difficulties.
The emotional strain caused by stress increases the risk of alcohol and other illicit drug use and dependence. Moustafa et al. (2018) conducted an integrative literature review to determine the relationship between childhood trauma, early-life stress, alcohol and drug use, addiction, and abuse. The review findings illustrate that stress increases the risk of alcohol and drug use, addiction, and abuse among the victims. An explanation for the increased risk is the individuals’ lack of identification and implementation of effective coping strategies (Moustafa et al., 2018). Lack of effective coping strategies results in maladaptive measures such as illicit drug use and alcohol consumption. Extensive use of the maladaptive measures results in progressive addiction and drug abuse among individuals with an increased predisposition to other health effects. Alcohol consumption and other illicit drug use over time increase the risk of developing cardiac, respiratory, and liver conditions.
Conclusion
Stress is the emotional strain or tension experienced by an individual due to a reaction toward various demanding and influential situations. Individual response to stressors influences their health. Maladaptive response to stress results in various physical, psychological, and behavioral negative effects. Negative effects of stress on physical health include increased heart rates, sweating, high blood pressure, and long-term development of the cardiac condition. Psychological effects include the development of anxiety, depression, and bipolar disorders. The behavioral effects of stress on an individual include the development of eating disorders, altered sleeping patterns, impaired concentration, and abuse of alcohol and other drugs. Based on the research findings, it is essential for healthcare providers to identify strategic measures and health initiatives to educate and sensitize the community members on effective stress management approaches in all settings to aid in combating the health effects.
