After a person drinks alcohol, blood pressure, appetite, being thirsty, and the impulse to urinate increase while physical body temperature level and heart rate decrease.

MEDULLA-- The medulla manages the body's automatic actions, such as an individual's heart beat. It likewise keeps the body at the best temperature level. Alcohol really chills the physical body. Consuming a great deal of alcohol outdoors in chilly climates can cause a person's body temperature to drop below its normal level. This hazardous condition is called hypothermia.
