They decrease stage 4 and REM sleep
Studies have shown that individuals deprived of sleep for 24 hours, brain activity decreases significantly (up to 6% for the whole brain and up to 11% for specific areas). In humans, sleep deprivation also results in a decrease in core body temperature, a decrease in immune system function as measured by white cell count and activity, and a decrease in the release of growth hormone. Sleep deprivation has also been linked to increased heart rate variability. Keep in mind that everyone requires a different amount of time to sleep per day, so reaction to sleep deprivation may vary person to person.
Stage 2 of the sleep cycle usually lasts around 10 to 25 minutes and tends to make up around 45-55% of total sleep time. It is characterized by a decrease in body temperature and heart rate, as well as the presence of sleep spindles and K-complexes on EEG readings.
They will sleep during any time!
yes and no, I have a Chinese hamster and he is active in day time. But he/she will sleep allot in the daytime also unless trained not to. To train a hamster to sleep at night and play in the day is hard but doable just play with them for 10 minutes every 2 or 3 hours during the day then after a few days slightly increase the play time and decrease the sleep time in the day and after a few days do it again. And soon your hamster will play in day and sleep at night.
