> Biphasic sleep is still quite popular but it tends to be framed as taking a nap rather than as a 24-hour sleep regimen. That's right! here in the warmer and highly humid states of Mexico (mainly in the Yucatan peninsula) the Siesta is very popular. A lot of people sleep between 3pm and 5pm (when the heat and humidity are higher) and wake up early in the morning around 5pm . I never got used to sleep siesta, as always woke up groggy.
