Noonday naps, also known as SIESTAS, are a traditional practice in many cultures of taking a short nap during the day, usually in the afternoon. The term 'SIESTA' is derived from the Latin phrase hora sexta, meaning 'the sixth hour, ' referring to the mid-day break taken around noon. This practice is believed to have originated in Mediterranean countries, where the hot climate and long working hours made it necessary to take a break in the middle of the day.
