Why do you still feel tired at night when you’ve had frequent naps/didnt do anything all day?

In: Biology

The human body is simply programmed to respond to the day night cycle. When the sun goes down and it gets colder out your brain release melatonin which is the signal for you to go to sleep. No matter what you did or how you slept this response always happens.

Being asleep does more than replenish energy. It solidifies memories, as well as any learning you did that day. Beyond that, scientists recently discovered that sleep flushes neurotoxins from your brain. And we aren’t done learning about what is does for us, either! So make sure you sleep regularly, and don’t stay awake for much more than 16 hours.
