Every time she hears the lullaby from Lek she still falls asleep

Archaeological evidence suggests that parents have used lullabies to comfort and soothe their youngest for at least 4,000 years, but have you ever wondered why lullabies are so effective when it comes to putting a child to sleep?
Despite what seems to be general belief, lullabies do a lot more than put babies to sleep. Thanks to these songs’ rocking or swaying rhythm, lullabies recreate in a way the kind of movement sensations the baby experienced in the womb. This creates a physiological response in the body, and it has been proved to have far-reaching effects on health and the overall wellness of the baby
What’s more, if the video below is any indication of the truth, the effects of lullabies not only reach babies but animals as well.
Faamai is a big elephant, but every time she hears her caretaker sing a lullaby to her, she immediately falls asleep. Don’t believe me? Make sure to watch the video below and see the elephant’s incredible reaction to hearing her caretaker sing a soothing lullaby.
I don’t know about you, but I never would have believed this if I hadn’t seen it myself. Do you think it would work if there was a lion instead of that elephant?
