Since fever often causes discomfort and increases heart rate and metabolism, many people take antipyretics such as ibuprofen or acetaminophen (paracetamol). Aspirin is used as a treatment for adults but not in children due to the risk of Reye's syndrome. In cases where fever escalates so high that tissue damage is likely, the fever must be brought under control. General guidelines for diagnosing and treating fever differ depending on the age of the patient.
Food does not contain melanin. Melanin is derived from the amino acid tyrosine. Some foods that are high in tyrosine include seaweed, eggs, cheese, fish and various game meat. A tyrosine deficiency may lead to albinism.
Skin color is determined by a pigment (melanin) made by specialized cells in the skin (melanocytes). The amount and type of melanin determines a person's skin color. Melanin gives color to the skin, hair, and iris of the eyes. Levels of melanin depend on race and amount of sunlight exposure. Sun exposure increases melanin production to protect the skin against harmful ultraviolet rays. In addition, hormonal changes can affect melanin production.
