Optical radiation in modern medicine

Area of Science:

• Photobiology
• Dermatology
• Medical Physics

Background:

• Optical radiation, encompassing UV, VL, and IR, interacts with skin.
• Factors like ozone, sun position, and skin properties modulate radiation dose and effects.
• Ancient sunlight therapy has evolved into modern applications for diverse medical conditions.

Purpose of the Study:

• To review the mechanisms of optical radiation interaction with skin.
• To explore the therapeutic applications of UV, VL, and IR radiation.
• To highlight the role of optical radiation in treating various disorders.

Main Methods:

• Review of scientific literature on optical radiation and skin interactions.
• Analysis of photobiological effects based on wavelength and absorption.
• Compilation of current therapeutic uses in medicine.

Main Results:

• IR primarily transfers thermal energy; VL interacts thermally and photochemically; UV acts mainly photochemically.
• Skin's stratum corneum, epidermis, and dermis influence radiation absorption and effects.
• UV, VL, and IR are utilized in treating allergic, dermatological, cardiovascular, respiratory, rheumatic, neonatal, pediatric, and psychiatric conditions.

Conclusions:

• Optical radiation (UV, VL, IR) exhibits distinct interactions with skin.
• Understanding these interactions is key to their therapeutic efficacy.
• These radiation forms are valuable in modern medical treatments across multiple specialties.
