Jamie is dehydrated from playing a rough game of football on a hot summer afternoon. Explain why beer is not a good choice of beverage considering what you know about antidiuretic hormone.

Ethanol (alcohol) inhibits the release of ADH by blocking Ca2+ channels. ADH maintains water retention, and if you are dehydrated, you're going to need to retain all the water you can. Alcohol dehydrates you even more, so it would be a bad idea to have a beer right after

Antidiuretic hormone prevents urine production and promotes water retention by the kidneys. However, alcoholic beverages inhibit ADH secretion and result in a large output of urine. Jamie is already dehydrated and alcohol will only further that situation.
