[QUOTE="WPLG, post: 65039, member: 158"] New research has found that a stress transmitter wakes your brain more than 100 times a night and it’s perfectly normal. Dr. Samuel Gurevich, a pulmonologist and sleep specialist with Cleveland Clinic Weston, said it all has to do with the neurotransmitter noradrenaline, which is responsible for the “fight or flight” response. Noradrenaline triggers brain activity that we don’t even notice, but which is vital for a number of reasons. “And in fact what this research showed, it added to a large body of research that was already there, it confirmed that the brain is a very active organ, including when we sleep. This is what helps us remember, this is what gives us our energy back in the morning, this is what calms our nerves in the morning. So all the things that go along with good sleep, it’s not just because the brain shuts off when we sleep, it’s actually quite active but just in a very different way,” he said.
