How can alcohol effect homeostasis?

Answer 1

Yes to put it simply. Alcohol blocks the receptors that tell your body when your bladder is full, so your bladder keeps thinking it is full when it is not, this can cause dehydration, which can cause headache as seen in hangovers

Answer 2

Alcohol acts as a general central nervous system depressant, but it also affects specific areas of the brain.
Alcohol has been linked to disruption of hippocampal function. This impairs memory encoding since the hippocampus plays an important role in the formation of new memories.
Alcohol also impairs and alters functioning in the cerebellum, which affects motor function and coordination.
It has a notable inhibitory effect on neurons of the cerebral cortex, affecting and altering thought processes, decreasing inhibition, and increasing the pain threshold.
It also decreases sexual performance by depressing nerve centers in the hypothalamus.
Lastly, it depresses breathing and heart rate by inhibiting functioning of the medulla.
