Detailed explanation-1: -Owls sleep during the day and are awake at night because of their kind of: a. estivation.

Detailed explanation-2: -It has been suggested that a circadian rhythm of less than 24 hours predisposes one to the morning chronotype while a longer-than-24-hours clock may make for the ‘night owl’ chronotype. In addition to genetics, the daily routine, age, and other health conditions, may all contribute to the chronotype.

Detailed explanation-3: -As you’re probably aware, most owls are nocturnal animals. This means that they sleep during the day and are awake during the night to hunt for food and do all the other things that owls like to do.

Detailed explanation-4: -The light/dark cycle of the sun has a powerful effect on the circadian clock, sleep, and alertness. Your body’s circadian clock responds to light, as a signal to be awake, and dark, as a signal to fall asleep. Increase your amount of light during the day to be more alert.

Detailed explanation-5: -For morning larks, melatonin can rise around 6pm, making them feel tired by 9pm or 10pm. For night owls, melatonin can increase at 10pm/11pm or even later, meaning many aren’t tired until 2am or 3am. Genetics can determine your body clock type, but it’s also largely influenced by schedule and lifestyle.
