Sleep is the best meditation for Humans
Most sharks need to keep moving to breathe, so they engage in "active rest." While part of their brain rests, the other part remains alert, allowing them to navigate and avoid potential threats.
Bullfrogs are known to remain vigilant for extended periods without sleep. They can stay awake for months, especially during the breeding season.
Elephants, particularly adult males, sleep for about 2 hours a day, often during the nighttime. They can stay awake for extended periods, sometimes traveling long distances without rest.
Brown bats are nocturnal creatures that engage in short, intermittent periods of sleep throughout the day.
Adult walruses often sleep in the water, resting on ice floes or floating together in groups. They are known to sleep with their tusks hooked onto the ice for stability.
Horses, like giraffes, experience short periods of sleep, usually around 2 to 3 hours a day with a "stay apparatus" in their legs.
