3How Long Does Hangover Shake Last?
How long hangover shakes and tremors last may vary from person to person. Some factors may affect the duration, including the tolerance level of each individual to alcohol, the amount of alcohol consumed, and some personal characteristics, such as gender and weight. In most cases, symptoms tend to appear after 24 or 48 hours. If your body cannot process alcohol well, hangover shakes may persist up to 7 days or even lead to further complications. [4]
Why Do Hangover Shakes Occur
Many people usually associate hangover shakes and tremors with alcohol withdrawal. It turns out that these symptoms may result from the same changes in the nervous system that lead to withdrawal-linked tremors. When you consume alcohol, the body reduce the sensitivity or number of receptors binding to the GABA neurotransmitter, which produces calming effects. At the same time, it also increases the sensitivity or number of receptors binding to another neurotransmitter called glutamate, which can help reduce the sedative effects of alcoholic drinks. Nevertheless, when the alcohol leaves the body, the central nervous system and sympathetic nervous system remain unbalanced. This leads to tremors and shakes after a hangover.
Another reason is the effect of alcohol on the body’s ability to control levels of blood sugar. When you drink alcohol, blood sugar levels may become low and cause shaking, as well as other common symptoms of a hangover, such as headaches and sweating. [5]
