How are stress and exacerbations of allergic reactions connected?

The connection between psycho-emotional stress and the exacerbation of allergic or inflammatory processes in the body has been proven by numerous medical studies. When a person experiences chronic nervous tension, anxiety, or fatigue, their central nervous system sends signals to the endocrine system, leading to the release of stress hormones such as cortisol and adrenaline. In small quantities, these substances help cope with loads, but their excess during prolonged stress begins to suppress the body's protective functions and disrupt the regulation of the immune response.

Under the influence of stress hormones, the permeability of blood vessels and mucous membranes increases, which facilitates the penetration of allergens into tissues. In addition, stress promotes the activation of mast cells—the main participants in allergic reactions—which begin to release histamine more actively. As a result, a person notices that familiar symptoms, such as skin itching in dermatitis, asthma attacks, or hives, manifest much brighter and sharper precisely during periods of emotional loads, submitting projects at work, or personal worries.

Interestingly, this process also works in reverse: the constant physical and psychological burden of living with a severe allergy becomes a powerful source of stress in itself. A person begins to feel anxious before every meal, fear new contacts with potential irritants, or social isolation. This forms a vicious cycle where anxiety worsens allergy symptoms, and symptoms, in turn, increase stress levels and worsen the patient's overall quality of life.

Breaking this vicious cycle requires an integrated approach to health, including not only drug therapy but also work with the psycho-emotional state. To reduce the impact of stress on allergies, it is useful to follow these recommendations:
