The 8 Illnesses Caused by Stress

Prolonged stress has been shown to increase the risk of depression, insomnia, and contribute to autoimmune diseases, cancer, and cardiovascular disease, according to various studies. The US National Institutes of Health defines stress as the body and brain’s reaction to external factors, which can be acute, short-term, or chronic. Chronic stress can lead to harmful changes in the body that contribute to the development of certain diseases.

Depression is strongly linked to uncontrolled chronic stress, as cited in a 2021 review conducted by the University of Karachi, Pakistan. Persistent stress triggers the production of certain hormones and chemicals that negatively impact the body’s organs. Additionally, a 2007 review from the University of British Columbia revealed that individuals who experience major stressful events may develop depression over time.

Insomnia has been directly linked to stress in a 2013 survey by the American Psychological Association that included nearly 2,000 adults. The survey found that stress causes individuals to lose sleep, with 43% reporting sleep disturbances at least once a month. Stress can also weaken the immune system, making the body more susceptible to infectious diseases like colds, as demonstrated in a 2005 study from Carnegie Mellon University.

Research indicates that prolonged stress can increase the risk of cardiovascular disease and stroke, as found in a 2021 study from the University of Gothenburg, Sweden. Muscle tension caused by stress can lead to chronic pain conditions, such as migraines and lower back pain, according to a 2021 study by Soonchunhyang University, South Korea. Additionally, stress may play a role in the onset of cancer and can exacerbate autoimmune diseases.

A 2018 study from the Karolinska Institute, Sweden, revealed that patients with stress disorders were more likely to have autoimmune disorders than individuals without stress disorders. Autoimmune conditions like multiple sclerosis, rheumatoid arthritis, and lupus can be worsened by stress. Tight muscles caused by stress can trigger or worsen chronic pain conditions, leading to discomfort and reduced quality of life.

In conclusion, it is essential to manage stress effectively to protect both mental and physical health. Implementing stress-reducing techniques such as mindfulness, exercise, and relaxation strategies can help mitigate the negative effects of chronic stress on the body and mind.
