Yliherkistyä

Yliherkistyä is a Finnish verb that translates to "to become hypersensitive" or "to overreact." It describes a state where an individual exhibits an exaggerated or unduly strong emotional or physical response to a stimulus. This stimulus can be anything from a particular food or substance, leading to an allergic reaction, to a social situation or comment, resulting in a disproportionate emotional outburst.

In a physiological context, yliherkistyä refers to the immune system's overreaction to harmless substances, commonly known as allergies. The body mistakenly identifies these substances as threats and mounts an immune response, leading to symptoms like itching, swelling, or respiratory distress. This hypersensitivity can develop over time.

On a psychological or emotional level, yliherkistyä describes a tendency to perceive situations or remarks as more threatening or significant than they are. This can manifest as heightened anxiety, defensiveness, or a feeling of being personally attacked. Someone who yliherkistyy might be described as easily offended or overly sensitive. The causes of such emotional overreactions can be varied, including past experiences, personality traits, or stress levels. The term implies a deviation from a more typical or expected response.
