Hello, I’m Dr. Ingrid Mathieu and I’m a clinical psychologist. Today we’ll be discussing what is a hangover for About.com.A Hangover is a cluster of symptoms that usually develop the morning after a heavy night of drinking. The symptoms can range from mild to severe and include headache, body ache, nausea, sensitivity to light and noise, lethargy, vomiting, diarrhea, insomnia, dry mouth and thirst. Psychological symptoms can include heightened feelings of irritation, depression and anxiety.Since every individual reacts differently to alcohol, there is no set amount that will determine whether or not you experience a hangover. Generally speaking, the more you had to drink, the more severe the hangover.Although there are many folk remedies that have been used over the years, there is currently no empirically valid way for not getting a hangover except of course for not drinking any alcohol. Additionally, the only way to rid oneself of the alcohol they have consumed is time. You have to wait for the body to metabolize it.This is Dr. Ingrid Mathieu for About.com. Thank you for watching.
