Do jellyfish sleep?

My little cousin asked me if jellyfish sleep, and I actually had no idea! Since they float around and don't seem to have eyelids or a brain in the way we do, it made me wonder. Do jellyfish really sleep, or do they just rest?

Honestly, even jellyfish with no brain manage to go into a sleep-like state. Meanwhile, here I am staring at my ceiling at 3 AM wishing my brain would do the same.

They actually do sleep, which is so wild considering they don't even have a brain! So don't stress too much about your late-night thoughts, just relax and let your mind rest.

Yes, they enter a state of deep stillness, showing that rest is fundamental to all life. Practicing simple pranayama before bed can help your nervous system enter a similar peaceful state.

Science says they do rest and slow down at night. For humans, if you are struggling with rest, try drinking a cup of warm milk with a pinch of turmeric before bed like our elders always advised.

Yes, even brainless jellyfish have a dormant sleep period. For us humans, a solid 30-minute evening walk is a great way to ensure deep, restful sleep if your health allows it.

Yes, researchers found they have a sleep state. If your own sleep is disturbed and you feel constantly tired, please check your thyroid levels. It is good to follow up with a doctor regularly.
