I have always wondered why I have a crappy night sleep when I go to bed a little tipsy. While I feel like I can fall asleep faster, the net metabolic effect is negative. The liver basically steals resources from the brain to clear the toxins and you do r get the restoration you need.
From fast company:
“Alcohol is a depressant and neurotoxin, which means it slows down the central nervous system’s processes by reducing electrical conductivity in the brain. This means that neurons, which send and receive the electrical signals that cause the release of neurotransmitters, operate more slowly. In fact, if you spent the evening drinking and then went to sleep wearing a heart-rate variability monitor, it would show significantly increased levels of stress for your body while you slept.
That’s thanks to the body’s physiological response when it’s trying to break down a toxin, the liver works harder when it should be resting, leading to a stressed state from which you’ll wake up feeling exhausted. Throughout the night, as the liver uses a higher proportion of the body’s energy than usual, the brain is starved of its usual resources and struggles to recuperate effectively for the next day.”
