Terveellis

Terveellis, also known as tingling sleep or mozzett, is a type of polyphasic sleep pattern in which the individual takes multiple, non-consecutive naps throughout the day rather than following a traditional single long sleep period.

The practice of terveellis has its roots in ancient Greece, where it was described by philosophers such as Aristotle and Epictetus as a way to conserve energy and increase productivity. The concept was revived in the 20th century by research into polyphasic sleep, particularly by William Dement, a well-known sleep expert.

Individuals who practice terveellis typically take between three and six 20-30 minute naps per day, spaced at intervals of several hours. The naps can be taken at any time of day, and the goal is to provide adequate rest without entering into deep, non-REM sleep for long periods.

Proponents of terveellis claim that it can improve cognitive function, increase alertness, and enhance creativity. They argue that the multiple naps provide a refreshing respite from the demands of daily life, as well as increasing the brain's ability to consolidate memories and learn new information.

However, the available scientific evidence for the benefits of terveellis is limited, and many experts remain skeptical about the claims made on its behalf. A longer sleep period is widely deemed essential for overall health and well-being, and some research suggests that polyphasic sleep may negatively impact physical and mental health. As a result, terveellis is not widely accepted as a standard sleep pattern.
