SLEEPLESS WONDERS

  5 ANIMALS THAT ALMOST NEVER SLEEP

Animals like stone beings defy nature's laws, need less sleep. When people recharge during sleep, while some animals are adapted to their environments function with minimal sleep.

Here is a list of 5 animals who almost never sleep

Dolphins 

Dolphins are intelligent, cheerful water animals that must surface frequently for air. This leads them to sleep in short periods, with one brain hemisphere active at a time

Sharks 

Sharks have unique sleep patterns where they enter a tonic immobility state, sinking to the ocean floor while remaining alert.

Alpine Swifts 

Alpine Swifts have the unique ability to sleep on the wing by engaging in unihemispheric slow-wave sleep, allowing them to stay in flight for extended periods and only land for nesting.

Horses 

Horses have been popular for a long time due to their endurance and ability to stay awake for long periods. They do sleep, but in short breaks or naps.

Giraffes

Giraffes don't sleep for long periods like humans but in short bursts. They often sleep standing up, ready to react to threats due to their prey animal.
