Naruto Question: In naruto, do the ninja sleep. If they do, wont it be easy to kill them all?

Question

I know naruto kinda sleeps. But what if someone broke in and killed him?

Answer 1

When in your own village, sleeping wouldn't really be a problem, since you have security forces like ANBU around all hours of the day. But logically, they would be trained to be light sleepers back in the academy. And as mentioned before, meditation is an established option, as Gaara used meditation instead of sleep every night for years, so as not to let Shukaku out.

Answer 2

They are probably light sleepers so if anyone came into their room they would wake up.

Answer 3

they do sleep but in some reasons... They can sense the chakra of their enemy *since they can already differentiate a friend or a foe's chakra* that makes them alert all the times.. And during in their training in the academy they where thought to be alert all the time

Answer 4

They are very light sleepers - they wake easily. The best ninja also have the ability to meditate instead of sleeping. Kakashi is known for his ability to do so for example. To top it off, they have ninja guarding the village in shifts throughout the night, usually chuunin, who sound the alarm if there is anything out of place.

Answer 5

I guess it wouldn't go with a skilled ninja, but maybe with a lower ranked one. Or Naruto, he's kind of stupid XD But what would the manga look like if all they did was killing each other while sleeping?
