Hangovers appear to be the body's form of warning us about the dangers of excessive consumption. It is a collective effort biologically: The most common symptoms include diarrhea, exhaustion, headache, nausea, and trembling. When the "fight or flight" mechanism is triggered, systolic (top) blood pressure rises, the heart pumps quicker than expected, and sweat glands overproduce. Some people develop an aversion to light or sound. Others feel like they are spinning (vertigo).

As diverse as the signs, the causes are as well. Alcohol breaks down into acetaldehyde, which is poisonous at high concentrations. However, since concentrations rarely reach that level, this is not the whole story.

A hangover can be a type of sleep deprivation since drinking collides with brain function when sleeping. Since alcohol disrupts the hormones that control our body clock, a hangover may feel like sleep deprivation and vice versa. Since alcohol may cause migraines, some individuals can mistakenly believe they are sick when they are actually suffering from an alcohol-induced headache.

When blood alcohol concentrations start to drop, hangovers begin. Indeed, some researchers believe that when levels hit zero, the worst problems appear.

1. Dog's hair.  Getting the hair of the dog that bit you, is a term used to describe drinking to relieve hunger pangs. Hangovers are thought to be a form of alcohol withdrawal, so a couple of drinks as your Hangover Killer can help.
2. Make sure you get enough water. Since alcohol prevents the release of adenosine, a hormone that causes the kidneys to produce less urine, it encourages urination. You could be even thirstier if your hangover involves nausea, sweating, or coughing. Even if nausea makes swallowing difficult, a few sips of water can be enough to alleviate your hangover.
3. Consume any carbs. Since drinking lowers sugar levels, some of the nausea and headaches associated with a hangover could be explained by the brain's inability to function without of its primary fuel. Furthermore, many people fail to eat while they drink, causing their blood sugar levels to drop even further. To softly nudge levels to normal, combine toast and juice.
4. Stay away from alcoholic drinks that are dark in colour. Clear beverages, such as vodka and gin, have been shown to induce fewer hangovers than darker liquors, such as rum, red wine, and jim beam, according to studies. The most common form of alcohol found in alcoholic drinks is ethanol, but dark liquors also contain scientifically metabolites (congeners), such as methanol. The same enzymes process methanol, according to experts, but methanol compounds are more toxic, which may lead to a worse headache.
5. Have a cup of coffee or a cup of tea. Caffeine does not have unique anti-hangover properties, but as a stimulant, this could alleviate grogginess. However, since coffee is a diuretic, it can make dehydration worse.

B vitamins and zinc are two of the most important nutrients in the body. The diets tested for 24 hours before and after heavy drinking in a report published recently. The findings were focused on the participants stating what they consumed in a small sample. They did discover, nevertheless, that people who consumed more zinc and B vitamins as their Hangover Cure in their food and beverages suffered from less hangovers.
