Environmental and Biological Factors

2.1 Environmental Changes Increasing Itchiness Risk

  • Climate: Changes in temperature, humidity, and climate can increase the risk of itchiness. The skin often reacts to environmental fluctuations by becoming dry and irritated, creating favorable conditions for itchiness.
  • Chemical Exposure: Contact with chemicals in the environment, such as at work or home, can cause skin irritation and itchiness.

    • Biological Factors: Biological elements like allergens can trigger skin reactions, leading to allergic responses and itchiness. Identifying and avoiding these factors is crucial in managing itchiness.

Through understanding medical causes and environmental factors, physicians can develop appropriate treatment plans to alleviate itchiness symptoms and improve the quality of life for patients.


Impact on Psychology and Quality of Life

Experiencing itching all over the body without a clear cause significantly affects the psychological well-being and quality of life. Patients often feel anxious and stressed. Sleep is affected. The ability to concentrate on work or studies diminishes. The higher the level of itching, the more negative the impact. This can create a vicious cycle when the itching is persistent. Therefore, it is essential to seek medical examination and analyze the characteristics of the itching to identify its cause, thereby enabling effective treatment. Early treatment helps reduce the negative psychological impact of generalized itching.
