What are night sweats?
Night sweats, also known as nocturnal hyperhidrosis, pertains to excessive sweating at night. It is normal for anyone to sweat. Our sweat glands continuously work throughout out the day and night. However, if you have woken up at night to find that your bedsheets are drenched in sweat, then you are most likely experiencing night sweats. But if the sweating is due to hot temperature or the too warm bed sheets, then it's not night sweats. When a person experience night sweats, they usually experience it whilst the surrounding temperature is cold.
Night sweats are usually harmless, but sometimes it may be a sign of an underlying medical condition. Such medical conditions include hypoglycaemia, hyperthyroidism, and infections. Certain drugs, such as antidepressants and hypoglycaemic agents, can also cause night sweats. Another common cause of night sweats are alcohol and/or drug abuse. You may experience night sweats if you are an alcoholic, a binge drinker, or even if you just had one glass of alcohol.
How does alcohol cause night sweats?
Why do people sweat after consuming too much alcohol? The reason behind this is alcohol metabolism. Just like anything else that you ingest through your mouth, alcohol also enters your intestines and is absorbed into your blood vessels. The absorbed alcohol is then carried to your liver where the alcohol is metabolized. The liver synthesizes enzymes that will help breakdown the alcohol before the molecules are absorbed. This is a time-consuming process and your liver can only digest a certain amount of alcohol at a time. Therefore, if you consume alcohol at a faster rate than the rate of your liver's metabolism, then your liver will fail to metabolize the excessive alcohol. This excessive alcohol will remain in your blood stream, giving rise to many side effects such as sweating.
Alcohol is a central nervous system depressant. It also affects the cardiovascular system and every part of your body. Therefore, consuming alcohol can make your heart beat a whole lot faster and dilatation of the peripheral blood vessels. When these blood vessels are dilated, you will sweat a lot more than usual, and you may experience this in the form of night sweats.
Night sweats may also occur during the withdrawal phase of alcohol drinking, but this is only temporary.
Does this mean that you are losing alcohol through sweat?
Yes, you are losing a small amount of alcohol through sweating. Majority of the alcohol you consume is absorbed through your intestines and is metabolized in the liver. But only 10% out of this consumed alcohol leaves the body through urine, breath, and sweat. The rest is broken into small by-products in the liver through the process of metabolism.
