Food and Alcohol Sweats


Sweating When Eating

Sweating during or after eating – called gustatory sweating – is caused by hot drinks and hot or spicy food. They raise your internal temperature, activating your body’s cooling mechanism.


What Causes Sweating When Eating?

Spicy food and hot drinks before bed can cause night sweats, as your body is trying to cool you down. Caffeine stimulates your sweat glands and alcohol widens the blood vessels in your skin, which can also make you sweat more.

Sweating when eating can be a problem for some people – occasionally just thinking about food can make someone sweat. This can be linked to a malfunction in saliva production. Nerves that cause us to salivate get confused with nerves in our sweat glands, so we sweat instead of producing saliva.

If you’re concerned about gustatory sweating, speak to your doctor or a professional medical adviser.


Does Food and Drink Sweat Smell?

Body odour can be caused by some foods. Onions, garlic, spicy foods and dairy products can all cause your sweat to smell. Overconsumption of alcohol can also make your sweat smell.


Alcohol Sweats

Alcohol causes our body temperature to rise by increasing our blood flow and sugar level, so we sweat more to compensate. The body also views alcohol as a toxin, so it works harder to get rid of it via our liver, but also through urine and sweat. Alcohol night sweats are a symptom of drinking too much.


How Can I Stop Sweating When Eating or Drinking?

•             Avoid trigger foods – like very hot or spicy food.

•             Cut down on alcohol consumption.

•             Stay hydrated at all times – especially during and after alcohol consumption.

•             If you’re concerned about how much you sweat when you eat or drink, then speak to your doctor.
