The Impact of Pessimism on Humans
Pessimism can have detrimental effects on an individual’s physical, mental, and social well-being. Below are some of the most significant negative consequences associated with a pessimistic outlook:
Increased Likelihood of Anxiety, Depression, or Social Isolation
Pessimistic individuals are more susceptible to depression, as noted by psychologist Martin Seligman. A 2013 study by the British Broadcasting Corporation revealed that negative thoughts could trigger or exacerbate episodes of depression or anxiety, ultimately affecting an individual’s overall well-being.
Anxiety can interfere with various aspects of life, including restful sleep, which is often compromised due to excessive worrying. Moreover, those with a pessimistic mindset may find it challenging to trust others for support, leading them to refrain from seeking help, thereby increasing their sense of isolation.
Harm to Brain Cells
Constantly anticipating the worst can lead to an increase in cortisol production by the brain, a hormone associated with stress. According to family and emergency medicine doctor Janet Neshat, elevated cortisol levels resulting from stress can reduce brain volume.
Numerous studies have indicated that stress can kill new neurons in the hippocampus, a brain region closely linked to memory, emotions, and learning.
Increased Risk of Heart Disease Mortality
Pessimistic behavior is associated with a higher risk of death due to heart disease, while an optimistic outlook appears to have no detrimental impact in this regard. This finding was highlighted in a 2016 study led by psychiatrist Miko Pankalainen at Päijät-Häme Central Hospital in Finland.
The study involved presenting 2,267 men and women aged between 52 and 76 with both positive and negative statements, asking them which phrases resonated most with them. Additionally, cholesterol levels, blood pressure, and other health and behavioral characteristics were recorded.
After an 11-year follow-up period, 122 individuals had succumbed to coronary heart disease. The researchers discovered that the deceased had shown a significantly higher degree of pessimism compared to their counterparts. Furthermore, other studies suggest that optimism may contribute to a longer life span.
It is important to note that pessimism is not an inherent trait that defines a person for life. Research indicates that individuals can learn to cultivate a more optimistic outlook.
