People repeatedly and rapidly forget and re-discover that emotional status has a direct and profound influence on physical and mental health ⁷. Freud discovered links between repression of emotion and physical symptoms nearly a century ago. Wolff and his colleagues also documented fixed physiological responses to emotional activation in more than three decades worth of research ⁸. More recently, research findings have been adding up in support of the notion that the relationship between emotional and physical health is direct and reciprocal. Research has shown that over 80% of all physicians’ visits have to do with a socio-emotional challenge, while just only 16% could be considered solely pathophysiologic in nature. One study discovered that 84 % of 567 common complaints, such as dizziness and chest pain, indicated no medical diagnosis ⁹. A recent study out of the UK discovered that about 25% of all new specialty referrals and about 20% of all referrals requiring surgery resulted in no particular medical diagnoses ¹⁰. It becomes imperative and clear that a more keen understanding of the roles of emotions in the occurrence and progression of symptomatic suffering is necessary in order to curtail the staggering amount of medical costs spent involved in diagnosing these symptoms that are borne out of emotional imbalance. Abbass (2002) further made this very clear by documenting the enormous cost savings to the system when such cases are given brief emotionally focused psychotherapy ¹¹. Learning and understanding how and when such therapies come into the treatment plan of medical systems will be a great service to all and sundry.

The ways in which humans manage their emotions has become one of the most important but least examined concerns in medicine today. Emotions are physiological phenomena ¹². When poorly managed or regulated, they can lead to negative health and psychological consequences ¹³.

One important factor that links emotions and health disorders has to do with the (dys) regulation of emotions ¹⁴. Patients with difficulties in managing their emotions subject their health and wellbeing into gross negligence and as a result are more likely to display a history of substance abuse, poor nutrition, and disordered eating, lack of exercise, abnormal sleep patterns, poor compliance with medical interventions and behaviors that are injurious to one self. These patients make use of medical services like emergency rooms and medications, at tremendous rates. Because they often fail to stick to the directives of medical advice and treatment prescriptions, such patient s create conflicts with health workers and are more likely to file complaints in the court than patients that are emotionally healthy and stable ¹⁵.

It is important to acknowledge that feelings and emotions are not responsible for health disorders and sicknesses. Rather it is the protracted reliance on self-defense against the expression of emotions and feelings that creates the tension required for the disease to thrive ¹⁶. Conversely, the free and uninterrupted expression of emotion possesses clear and sustainable benefits for physical and mental health and general wellbeing. In fact, research on aging and longevity has demonstrated that psychological factors bordering on emotions are more important predictors of a long, healthy life than other factors like diet and activeness ¹⁷. Individuals who remain actively involved in issues of life has a sense of hope and sheer optimism and can deal with moments of sadness by finding purpose and meaning, instead of bowing to depressed and despondency. They are also more likely to live longer and healthier than their pessimistic counterparts.

Studies by Pennebaker and his colleagues (1997) demonstrated that individuals who repress their emotions also suppress their body’s immunity, making them more vulnerable to a variety of illnesses ranging from common colds to cancer ⁵. Again, individuals who mask and deny their inward feelings, or outwardly vent their emotions, characteristically suffer most. “Studies of patients with serious medical conditions such as cancer, diabetes, kidney failure, and obesity, reveals that those who do not comply with medical advice also show strong use of defense mechanisms” ⁵. Other findings have demonstrated that patient with cancer and other forms of malignancy that chronically mask their experiences and feelings are more liable to die despite treatments than expressive patients ^{18, 19}. Empirical evidence indicates a substantial reduction in pain and discomfort from arthritis following the expression of negative. As a matter of fact, the amount of relief from pain and discomfort reported by patients with chronic illness has been found to be commensurate with how able they are too deeply and authentically express their emotions and feelings. The Table 1 shows some of the physiological manifestations repression of emotion health workers are likely to come across.

Repression of emotion is one of the most common strategies of regulating emotion used by humans. Clinical traditions made it clear that the psychological health of an individual depends on how effective impulses are managed or regulated; the consequences of effective regulation and management are, therefore, the main focus of researchers in clinical psychology. Gross & Levenson (1993) explained how the psychological consequences directly related to repression of emotion are subjects of frequent dispute among researchers ⁴. Researchers such as Cannon (1927) and Jones (1935) are of the opinion that suppressing a physical emotional response while emotionally prompted to express will increase the intensity of the emotional experience as a result of the concentration on suppressing the emotion ^{20, 21}. These researchers debate that common sense makes us understand that emotions become increasingly severe or intense the longer they are bottled up. Some other researchers such as Darwin (1872) and Tomkins (1984) express their disagreement with this theory with the view that emotional expression is crucial to the overall emotional response and that when there is repression, all other contingent responses (e.g. physiological) are weakened ^{22, 23}. Darwin (1872) and Tomkins (1984) threw more light on this argument by stating the obvious that people are taught to count numbers to ten when emotionally distressed in order to calm down ^{22, 23}. If repression of emotions were to increase the intensity of the expressible emotional experience, this counting tradition would only increase the response of the person emotionally aroused; however, the reverse is actually the case ^{22, 23}. Unfortunately, few pieces of research have been conducted to test these hypotheses ²⁴. The fact that people have contrasting opinions on which is the idea- to repress emotion by counting numerals to ten to calm down before acting or expressing the way you feel because repressing your emotions is injurious to your mental health is of increasing interest and concerns to experts in the psychology of emotions.

The various physiological, cognitive, and motivational, and physiological attributes of emotions may shed some light on their relation with hypertension as one of the risk factors of cardiac malfunction. Previous studies has indicated that stress is linked with increased cortisol levels, This has gained support from other research findings showing that how the body responds during stress depend on how one is able to deal with the stress ²⁵. Concealing and repressing emotions can give rise to stress-related physiological reactions. The occurrence of stress is as a result of the social disapproval and punishment of overt emotional expression that cause repression which is itself intimidating and stressful ²⁶. There are certain fields of human endeavor which require the repression of positive or negative emotions such as: estate agents who may hide their happiness when a good offer is tabled on house sake of maintaining their professionalism, or primary school teachers suppressing their anger or disappointment sake of upsetting their young pupils when teaching them good morals.

Recently, researchers have started to look into the effects which continual repression of emotion in the workplace may have on people ²⁷. Cote (2005) stated that continual repression brings about stress on individuals making use of it ²⁷. Stress brought about by such protracted repression of emotion can cause an increase in heart rate, anxiety, low level of commitment and other effects which can be detrimental to the productivity of an employee. The popular belief is that repression of emotion in the workplace is advantageous for the organization and dangerous for the employee on a long-term basis. However, Cote (2005) discovered that factors giving rise to the social dynamics of emotions determine whether regulation of emotion affects stress or not ²⁷. The repression of unpleasant emotions such as anger gives rise to elevated levels of stress.

Repression of emotion, as a strategy to regulate emotions, is useful in certain aspects of life such as supporting ambitions pursuits and bringing satisfaction to hedonic needs ²⁸. In as much as repression of emotion is regarded as a weak influence on emotional experience, it plays other useful roles. Repression of emotion is a goal-oriented strategy which is guided by people’s beliefs and customs and potentially by abstract ideas about the regulation of emotion ²⁸. In a research conducted by Larsen et al. (2012) the researchers investigated the possibility of a positive association between repression of emotion and symptoms of depression in adults and adolescents under the influence of peer victimization and parental support ²⁸. A reciprocal relationship was discovered to exist between parental support and symptoms of depression but there was no symptom of depression with peer victimization. Depressive symptoms were discovered in the subjects following decreased perception of parental support after a year.
