When we dream while sleeping, our brain is still buzzing with neural activity.

My question is, while my whole body sleeps and rest, what changes take place in cellular activity throughout my body? What are the effects of sleeping to a particular cell of my body? Do individual cells themselves take rest and be in a non-active state like us humans? (Basically, do cells sleep?) Also, how does thinking affect our cellular activities and cells in general? Is there a connection to thoughts (neurons firing) and cells?

    $\begingroup$ There's a whole lot of cells in the body. I expect this might be a bit broad, but let's see how the community perceives this. $\endgroup$ – Steven Jeuris Feb 12 at 21:28

    $\begingroup$ There are a lot of questions here, some of them maybe belong on the biology stack rather than psychology, the question body does not match the title, and as Steven said, this is a broad topic, so I'm going to close this question. Please edit it down to something manageable and on-topic, and it can be considered for reopening. $\endgroup$ – Arnon Weinberg Jun 16 at 5:25
