There are lots of reasons and explanations for this.
Here are two:
As we grow older, our blood vessels typically harden and may narrow due to plaque buildup. When the body is getting ready to awaken hormones cause the blood pressure to rise and metabolism overall to increase. The narrower arteries in older people respond more quickly to this stimulus.
Another totally different reason deals with the purpose of sleep. Part of the reason a human needs sleep is that the brain needs time to assimilate short term memories into long term memory. Nearly all long-term memory is actually formed during sleep. Older people have fewer new experiences to assimilate and more of the long-term memory storage area is already filled with stuff, so older people need less time to form long-term memories and therefore need less sleep.
Other reasons, to do with growth, physical changes, physical stress, etc., are also valid.
