This experiment is ridiculous.  Of course you&#x27;re going to be tired if someone jolts you awake every hour on the hour.<p>What would be way more interesting is to study people who wake up naturally multiple times per night to toss and turn.  I do this at least 5-10 times per night due to muscle aches and pains.  I fall back asleep very quickly.  I&#x27;ve been doing this for years, but do remember rare times when I&#x27;ve slept through the night and felt so fresh in the morning.
