The consumption of alcohol can produce a series of short-term effects on the mind and body. These effects can be mild to severe, including loss of coordination, vision problems, increased blood pressure, dehydration, and reduced core body temperature. And then you have the usual fatigue, headache, and nausea, which combined with a boat ride can guarantee you seasickness.
Alcohol also acts as a central nervous system depressant, meaning that it slows down brain functioning and neural activity in complex situations. Even if you do not feel the effects of alcohol the next day, alcohol has been found to remain in the bloodstream for up to 8 hours after consumption.
