The impact of daily stress on autoimmune conditions
Stress has a detrimental effect on immune health
For most people, stress is an everyday experience caused by all the small hassles you encounter in your daily life. But stress is also one of the key triggers of Hashimoto’s flare-ups, which contributes to faster aging (1).
What happens to your immune system under stress?
The immune system is one of the first protective mechanisms to be activated when you’re exposed to stress. When this happens, a major part of the brain and many hormone-producing glands are activated. Certain types of molecules—such as adrenaline and cortisol—are then released into the blood (2, 3).
Adrenaline and cortisol activate immune cells through small extensions on the immune cell surface, called receptors. When this happens, immune cells prepare to charge against the “enemy” (4), one of the hallmarks of long-term stress exposure (5). Long-term stress leads to chronic inflammation and increases the risk of developing autoimmune conditions (6).
Even stress from one’s past or childhood can cause the immune system to behave differently than it normally should (7, 8). Stress impacts hormones, and hormones impact the immune system—making immune cells produce more of the stress molecule cytokines, which causes changes in sleep pattern, depression, and appetite (9).
How stress ages the immune system
Chronic stress makes the immune system and entire body age an increased rate (10). It diminishes heart health and makes people more likely to become overweight and even obese (11,12).
As people age, their bodies becomes less capable to respond well to stress, as certain regions of the brain are no longer able to react to stress signals in a timely way (13). Thus, the stress hormone cortisol takes a longer time to be suppressed. Long term exposure to cortisol enhances inflammation (10).
Prolonged stress makes people significantly more likely to develop allergies and autoimmune diseases (14-16).
Alcohol consumption, smoking, malnutrition, and sleep disturbances all amplify the negative impact of stress on the body (17, 18). By reducing these behaviors, you can improve your immune and overall health.
Sex hormones—especially DHEA (dehydroepiandrosterone), a building block for both estrogen and testosterone—can tamper with the immune system as well (19).
Even unexplained health issues, like wounds taking a long time to heal, can be caused by the impact of high stress on the immune system (20).
Stress and sleep
Getting good sleep is important for maintaining low stress levels and keeping the immune system in check. Even just one night of bad sleep can mess up the immune system (21, 22).
Stress continuously and chronically activates the immune system. In the case of irritable bowel syndrome (IBS), high cortisol increases gastrointestinal (GI) symptoms, and can lead to autoimmune diseases (23,24). In people with autoimmune conditions, it takes much longer to stabilize the immune system and reduce flare-ups after being exposed to stress (25).
Emotional stress and the start of disease
About 8 in 10 people who have autoimmune diseases have experienced emotional stress before the onset of the disease (26).
Health interventions aimed at reducing stress have a positive effect on reducing autoimmune diseases (27)—they should be considered as part of a comprehensive treatment approach.
It has also been shown that people who lead a healthy lifestyle are more protected from inflammation and autoimmune flare-ups (28).
Mindfulness techniques, such as meditation, have been proven to work well for a large majority of people (29).
