The body's temperature LOWERS slightly during sleep. Actually, body temperature goes down at night generally speaking. The body is able to regulate body temperature between 96.8 and 100.4 degrees Fahrenheit. (When temperature goes outside of these bounds, it is not because of healthy body functioning -- it means you are sick or have hypo- or hyperthermia from environmental conditions.)
To begin with, the suprachiasmatic nucleus in the brain is like the body's internal clock. The suprachiasmatic nucleus reacts to changes in light. So when it's nighttime, certain things happen in the body, including a lowering of body temperature. Apparently, body temperature reaches a low at around 5:00 a.m.
Also, there are other more obvious reasons that the body's temperature lowers during sleep. When we are sleeping, our metabolism slows down, and we burn less energy. Also, our heart rate and circulation slows. In general, many of the body's functions slow down; you don't need them as much during sleep as you do when awake. This contributes to a lowering of body temperature. Also, the body is basically still (not moving) during sleep. This also contributes (although only minimally) to a lowering of body temperature.
Some animals do this to the extreme and can go into a state of torpor in which their body temperature drops to phenomenally low levels. Their heart rates also drop to levels that would kill animals that didn't have the ability to go into torpor. Humans go into torpor during sleep but only very minimally -- nothing even close to some other animals.

How do you wake my hedgehog up from hibernation?
It depends how long he's been hibernating. If you just caught it, then put him somewhere like under your shirt, somewhere warm and make sure to warm him up until he wakes up and seems active again. If it's any later you can't wake him up and, well to put it bluntly he's going to die. I'm sorry.
