Winter cold exposure can cause skin issues like xerosis and chilblain, and severe problems such as frostbite and hypothermia. Environmental factors like wind and altitude influence the risk and type of cold-induced injuries.

Area of Science:

  • Dermatology
  • Environmental Medicine
  • Physiology

Context:

  • Winter climate poses risks for skin and systemic health due to cold exposure.
  • Cold-induced skin conditions include xerosis, chilblain, and cold panniculitis.
  • Severe cold exposure can lead to frostbite and hypothermia.

Purpose:

  • To summarize the various cutaneous and systemic alterations induced by cold exposure.
  • To highlight the factors influencing the development of cold-related pathologies.
  • To inform about the spectrum of cold-induced injuries.

Summary:

  • Cold exposure impairs skin barrier function, causing xerosis (dry skin) and affecting dermal vasculature (chilblain).
  • Lipid crystallization in adipocytes leads to cold panniculitis.

  • Beyond the skin, severe cold can cause frostbite and systemic hypothermia.
  • Environmental factors (wind speed, altitude, humidity) and exposure duration/intensity dictate injury type.
  • Ultraviolet radiation in winter can also cause skin lesions.

    • Impact:

    • Understanding cold-induced pathologies is crucial for prevention and treatment strategies.
    • Awareness of environmental risk factors can mitigate adverse health outcomes.
    • This information is vital for public health advisories during cold weather seasons.
