Djersë

Djersë is the Albanian term for sweat, the moisture produced by sweat glands in the skin as part of the body's thermoregulation and maintenance of internal balance. Sweat helps cool the body through evaporation and also plays a role in skin health and mineral balance.

Sweat is mainly produced by eccrine glands, which are widespread and secrete a clear, watery fluid containing salts and small organic compounds. Apocrine glands, found in areas such as the armpits and groin, secrete a thicker fluid that can contribute to body odor when broken down by skin bacteria. The composition of sweat varies with hydration, diet, and environmental conditions, but water and electrolytes are the dominant components.

The production of djersë is controlled by the autonomic nervous system and the hypothalamus. Thermal stress from heat or exercise stimulates sympathetic cholinergic nerves to the eccrine glands, releasing acetylcholine. Emotional stimuli can also trigger sweating, especially on the hands, feet, and face. Factors such as age, fitness, and acclimatization influence how much a person sweats.

Clinical aspects include hyperhidrosis (excessive sweating) and anhidrosis (insufficient sweating). Abnormal sweating can be a symptom of health conditions, medications, or infections and may affect quality of life if persistent or localized.

In daily life, practical considerations related to djersë include hydration, climate control, and appropriate clothing. The frequency and intensity of sweating can vary with weather, activity level, and overall health, while remaining a normal and essential bodily function.
