Definition of somnolence

The word "somnolence" originated from the Latin words "somnus," meaning sleep, and "tolere," meaning to tolerate or endure. In the 15th century, the term "somnolence" emerged to describe a condition of drowsiness, lethargy, or lack of energy, often caused by excessive sleep or a physical or mental disorder. In the 17th century, the term was used to describe a type of mental fog or mental lethargy, making it difficult to focus or concentrate. Today, somnolence is used to describe a state of drowsiness, often experienced after a heavy meal, a warm bath, or due to a medical condition such as narcolepsy. Interesting, isn't it?
