Study Notes
Visible Light and Its Therapeutic Use
- Visible light has an important therapeutic use due to its energy properties and selective absorption in certain molecules.
- Exposure to visible light can cause significant physiological effects.
Phototherapy for Jaundice
- Jaundice is a condition characterized by an excess of bilirubin in the blood, often excreted by the liver in premature infants.
- In 1958, it was discovered that most premature infants recover from jaundice when their bodies are exposed to visible light, a process known as phototherapy.
- Phototherapy is an effective treatment for jaundice in premature infants.
