You may be wondering, how long does a hangover last? Hangovers are caused by a number of factors that revolve around alcohol, and understanding them is the first step towards learning not only how long your hangover will last, but how to prevent it the next time around. While everyone handles his alcohol a little differently (depending on age, weight, gender and many other things), and even though there is no universal answer for how long a hangover will last, you can learn why alcohol causes hangovers and how long alcohol takes to leave the bloodstream.
Hangovers happen because alcohol prevents the liver from supplying glucose to the body. This makes you feel tired, and combined with the dehydrating effects of alcohol can cause you to become achy, irritable and lethargic. The severity of a hangover can vary depending on many factors (such as how much you had to drink and how much you weigh), and because of this there is no concrete answer as to how long a hangover will last. Some people will take most of a day to feel back to normal, while some genetically lucky people rarely feel any symptoms of a hangover at all.
Once you have a hangover, there is very little you can do to lessen its duration. Common folk remedies, such as drinking coffee or taking a cold shower, may temporarily alleviate symptoms, but the hangover will inevitably kick back in afterwards, and caffeinated beverages may actually worsen symptoms in the long run by dehydrating your body further.
The best way to cure hangovers is to prevent them from happening. Drink one glass of water per hour while drinking, and eat before you head to the bar. Food in the stomach will slow the body’s absorption of alcohol, and water can keep you hydrated. Remember that hangovers are the body’s way of telling you to slow down; the worse the hangover, the easier you should be on yourself the next time around. And while there is no real answer to how long a hangover will last, keeping hydrated and planning ahead can spare you pain in the future.
