Chronic Stress Linked to Multiple Physical Diseases and Symptoms, Experts Warn

Chronic stress, often dismissed as merely causing fatigue, irritability, or sleep difficulties, can significantly impact nearly every bodily system when prolonged. Medical research increasingly shows that ongoing stress affects the immune system, heart health, skin conditions, digestive disorders, and may even trigger or worsen autoimmune diseases.

Skin diseases such as psoriasis are notably linked to stress, with flare-ups often occurring during periods of intense psychological pressure due to stress-induced immune and inflammatory responses. Similarly, the digestive system is highly sensitive to stress; conditions like irritable bowel syndrome (IBS) worsen with stress, affecting bowel motility, pain sensitivity, and gut microbiota. Inflammatory bowel diseases such as Crohn's and ulcerative colitis, while not caused directly by stress, can experience exacerbations triggered by it.

Autoimmune diseases including rheumatoid arthritis, lupus, and multiple sclerosis have also been associated with chronic stress. A large Swedish study published in JAMA found that individuals with stress-related disorders had a 36% higher risk of developing autoimmune diseases later in life. Stress also contributes to cardiovascular risks by elevating blood pressure, promoting inflammation in blood vessels, and disturbing heart rhythms, compounded by lifestyle factors like poor sleep and diet.

Additional effects of chronic stress include delayed wound healing, studies show healing can slow by about 24%, extending recovery by roughly nine days, and increased susceptibility to infections such as the common cold. Physical signs of stress include hair loss, digestive discomfort, worsening skin conditions, persistent fatigue, recurrent infections, sleep disturbances, and rapid heartbeat.

Experts emphasize that maintaining mental balance through adequate sleep, exercise, social connections, rest, and professional support is essential for overall health, just as important as nutrition and medical care. Dr. Roni Farber, head of public health at "Pami," highlights the broad physical toll of chronic stress and the importance of addressing it proactively.
