Introduction
In general, feeling cold and shivering after drinking alcohol may be caused by alcohol-induced blood vessel dilation, heat production from alcohol metabolism, hypoglycemia, common cold, acute alcohol poisoning, or cerebral hemorrhage. If such symptoms occur, it is recommended to seek medical attention promptly and receive targeted treatment after identifying the underlying cause. After alcohol enters the body, it causes peripheral blood vessels to dilate, increasing blood flow to the skin surface and accelerating heat loss from the body.
Generally, feeling cold and shivering after drinking alcohol may be caused by alcohol-induced blood vessel dilation, heat production from alcohol metabolism, hypoglycemia, common cold, or acute alcohol poisoning. If such symptoms occur, it is recommended to seek medical attention promptly to identify the underlying cause and receive targeted treatment. Specific analyses are as follows:
1. Alcohol-induced blood vessel dilation: After entering the body, alcohol causes peripheral blood vessels to dilate, increasing blood flow to the skin surface, which accelerates heat loss and leads to whole-body chills and shivering. In this case, it's important to stay warm—add clothing promptly and drink warm water to promote blood circulation and relieve chills.
2. Heat production from alcohol metabolism: The metabolic process of alcohol generates heat. Additionally, the body may increase heat production through shivering to accelerate alcohol elimination. Usually, no special treatment is required; symptoms typically subside naturally once alcohol is fully metabolized. Adequate rest can help the body recover.
3. Hypoglycemia: Alcohol inhibits the breakdown of liver glycogen, leading to decreased blood glucose levels and insufficient energy supply, resulting in chills and shivering. This is often accompanied by symptoms such as palpitations and hand tremors. Oral glucose tablets, glucose injection solution, or honey water can be consumed to quickly replenish sugar and alleviate hypoglycemic symptoms.
4. Common cold: After drinking, the body's immunity may decrease, making it easier to catch a chill and develop a cold, causing chills and shivering, often accompanied by coughing and runny nose. Under medical guidance, medications such as Ganmao Qingre Granules, Compound Paracetamol and Amantadine Capsules, or Yinqiao Jiedu Tablets may be taken. Rest and increased fluid intake are also important.
5. Acute alcohol poisoning: Consuming large amounts of alcohol leads to its accumulation in the body, impairing nervous system function and causing chills and shivering, often accompanied by confusion, vomiting, and other symptoms. Immediate medical attention is required. Doctors may administer emergency treatments such as Naloxone Hydrochloride Injection, Glucose Injection, and Vitamin B6 Injection.
In daily life, alcohol consumption should be moderate, and drinking on an empty stomach should be avoided. After drinking, maintain warmth and ensure sufficient rest. Seek medical help promptly if any discomfort occurs.
