Night sweats are a common symptom of alcohol withdrawal, and they can be both uncomfortable and disruptive to sleep. They are caused by the body's central nervous system, which regulates body temperature, struggling to readjust after prolonged alcohol exposure. This results in the body being unable to regulate its temperature, leading to excessive sweating. While night sweats are usually not dangerous, they can be indicative of more serious withdrawal symptoms, and in rare cases, they can cause dehydration. If you or someone you know is experiencing night sweats during alcohol withdrawal, there are several strategies to manage them, including maintaining a cool environment, staying hydrated, and practising relaxation techniques.

What You'll Learn
Alcohol withdrawal syndrome and the central nervous system
Alcohol withdrawal syndrome is a recognised series of symptoms experienced when someone who is physically dependent on alcohol suddenly stops or reduces their intake. The severity of withdrawal symptoms varies from mild, such as insomnia, trembling, and anxiety, to severe and life-threatening symptoms, including seizures and delirium tremens.
The central nervous system (CNS) plays a crucial role in regulating various bodily functions, including body temperature, blood pressure, and heart function. Alcohol is a powerful depressant that slows down the CNS, altering the way signals are sent and received. This results in a decrease in the rate of physical functions such as speech, coordination, and walking. To compensate, the brain and body over-generate signals, triggering psychological reactions like high body temperature, increased blood pressure, and excessive sweating.
During alcohol withdrawal, the CNS struggles to regain balance after prolonged alcohol exposure. The body begins to send out different signals to counteract the effects of alcohol. This results in neurochemical changes that can be minimised with drugs used for acute detoxification. Adaptations to the NMDA system occur due to repeated alcohol intoxication, contributing to the hyper-excitability of the CNS during withdrawal.
The severity of alcohol withdrawal symptoms depends on several factors, including the degree of alcohol intake, the length of alcohol usage, and previous withdrawal history. Symptoms typically appear within 6 to 24 hours after the last drink and peak in severity around 24 to 72 hours, improving by the seventh day. Mild symptoms include insomnia, mild anxiety, and headaches, while more severe symptoms can include seizures, hallucinations, and delirium tremens.
Managing alcohol withdrawal symptoms often involves seeking medical support and treatment. Benzodiazepines are commonly used in pharmacological treatment, with dosages based on individual symptoms. Thiamine is also routinely recommended, and addressing electrolyte problems and low blood sugar is crucial. Early treatment improves outcomes and helps prevent severe complications.

Alcohol intolerance and genetic factors
Alcohol intolerance is mainly due to genetic variations that affect the enzyme aldehyde dehydrogenase 2 (ALDH2). People with alcohol intolerance have a genetic mutation that makes it hard for their bodies to break down alcohol when they drink. This is caused by inherited (genetic) traits most commonly found in people of Asian descent.
Alcohol intolerance is not an allergy. It is an inherited genetic disorder that impairs alcohol metabolism. The increased accumulation of acetaldehyde in affected individuals due to deficient aldehyde dehydrogenase enzymes often leads to the characteristic symptom of having flushed skin. On the other hand, the less common alcohol allergy is an immune system reaction to alcohol (specifically ethanol) that causes symptoms such as rashes, difficulty breathing, and anaphylaxis in severe cases. Nausea is a symptom common to both alcohol intolerance and alcohol allergy.
According to the National Institutes of Health, peer relationships are consistently linked to alcohol use in college students. A recent study found that 61% of teens and young adults surveyed admitted that friends and peers influenced their decision to drink alcohol. This highlights the importance of understanding the genetic factors contributing to alcohol intolerance, as young people are particularly vulnerable to the negative effects of alcohol.
Research has identified various genes that are associated with alcohol intolerance and metabolism. For example, the ADH1B and ADH1C genes are involved in the first step of alcohol metabolism, converting ethanol to acetaldehyde. Variants in these genes can increase ADH enzyme activity, leading to a buildup of acetaldehyde. The ALDH2 gene is involved in the second step of alcohol metabolism, converting acetaldehyde to acetate. A common variant in this gene decreases ALDH enzyme activity, slowing the removal of toxic acetaldehyde.
In addition to these specific genes, complex phenotypes related to alcohol sensitivity are influenced by dynamic networks of interacting genes. Both genetic and environmental factors contribute to the variation in the inebriating effects of alcohol and alcohol addiction among individuals. While there is no single locus that predisposes an individual to alcohol abuse, the interaction of multiple genetic variants and environmental factors shapes alcohol-related phenotypes.

Managing symptoms: staying cool
Night sweats are a common symptom of alcohol withdrawal. They occur as the body's internal systems, which have been affected by alcohol, change back to their normal states. This includes the central nervous system, which regulates body temperature and sweating, and the cardiovascular system. When alcohol intake is stopped, the body goes into shock, craving the depressant effects of alcohol. This can lead to anxiety, insomnia, and tremors. Severe symptoms such as sweating, nausea, and hallucinations can peak within 24 to 72 hours.
- Keep the bedroom cool and well-ventilated by using fans or air conditioning.
- Use light and natural bedding materials, such as cotton or bamboo fibre, to help wick away moisture and keep you dry.
- Look for a cooling pillow cover to help regulate temperature.
- Wear lightweight and breathable sleepwear made from natural fibres to keep you cool and comfortable.
- Stay hydrated by drinking plenty of water throughout the day. Alcohol withdrawal and night sweats can lead to dehydration, so it's important to replenish fluids.
- Practise relaxation techniques such as deep breathing, meditation, and progressive muscle relaxation to reduce stress and anxiety levels, which can contribute to night sweats.

Managing symptoms: hydration and diet
Staying hydrated is essential when experiencing night sweats during alcohol withdrawal. Detoxification is challenging, and the body needs a lot of water to flush out toxins. Make sure to drink plenty of water during the day to support your body's natural detoxification process.
It is also important to replenish fluids lost through sweating. Profuse sweating can lead to dehydration, which can be dangerous, especially when combined with vomiting or diarrhea. Therefore, drinking enough water is crucial to managing night sweats and preventing further complications.
In addition to hydration, maintaining a healthy diet can help reduce the severity and duration of night sweats. Eating well provides the body with the nutrients it needs to recover and adjust to functioning without alcohol. A well-balanced diet can also help regulate blood sugar levels, which is important because low blood sugar can also contribute to night sweats.
While there is no specific diet recommended for managing night sweats, a healthy and balanced diet can support overall health and well-being during alcohol withdrawal. It is also beneficial to avoid caffeine and sugary drinks, as these can disrupt sleep and contribute to dehydration. Instead, focus on drinking plenty of water and consuming nutritious foods to support your body during this challenging time.
In summary, staying hydrated and maintaining a healthy diet are crucial aspects of managing night sweats during alcohol withdrawal. Detoxification places significant demands on the body, and proper hydration and nutrition provide the body with the tools it needs to heal and recover.
