Why Does Coffee Make Me Sweat?

If you are anything like me, you need that cup of coffee (or two) in the morning to get going. However, coffee doesn’t just wake us up, but our central nervous system as well. The caffeine acts as a stimulant, and increases our blood flow, as well as your sweat glands. This makes it much more likely for you to produce sweat.

There are a few ways to fight the coffee sweats though. Some of the recommended approaches include eating food with your coffee, switching to a decaf alternative, or to brew your own coffee so you can monitor exactly how much you are making. Overall, consider lowering your caffeine intake if you want to combat the coffee sweats.

While it may be challenging at first to change your morning coffee routine, there are many viable alternatives out there to get your morning fix of coffee without the caffeine and the sweating.

Can Drinking Coffee Cause Night Sweats?

If you have suffered from night sweats or sweating in the night and you have no heating on, you may wonder what causes them. Night sweats are not really a cause of concern unless you feel unwell, which means you should consult a medical practitioner. There can be a number of causes of night sweats (including medical conditions or menopause), but you may be surprised to learn that one of the main culprits is drinking coffee!

Coffee contains caffeine, (which is a stimulant) and this causes your nervous system to increase the metabolizing process, which in turn causes you to sweat to regulate your body’s temperature.

By reducing your intake of caffeine during the day you may notice your night sweats start to decline and this will be confirmation that this is the root of your symptoms.

Night sweats are not really a cause for concern unless you feel unwell, at which point you should consult a medical practitioner.

Can drinking coffee cause body odor?

The smell we give off from our body, and even bad breath, has its explanation, and we can find it in the food we eat.

As explained by the nutritionist Jessica Hierro to El País, the coffee we drink at breakfast increases bad breath and sweating due to the volatile sulfur compounds and tannins of this product.

“Caffeine stimulates the nervous system and can produce an increase in the production of sweat. This effect will be greater or lesser depending on sensitivity and the amount consumed,” he said.

He also explained that coffee produces dehydration and dryness in the mouth which produces the evaporation of gases that produce bad odor.

The body’s chemicals are directly affected by the excessive consumption of caffeine, usually causing increased sweating in those who consume it, since its diuretic effect increases the capacity of secretion of the body’s sweat glands.

So yes, coffee produces bad body odor.

3 Tips To Stop Coffee Sweats

Many of us drink coffee as part of our daily routine. But when you overdue it and start sweating somewhere where you might feel embarrassed (like in front of other people….), it can be an unpleasant experience. Here are 3 tips to stop coffee sweats:


When you grab a coffee on the go, you don’t exactly know how much caffeine has gone into your coffee. Brew your own! You can better control the amount of caffeine plus you can experiment with different kinds of coffee and find ones you love!

2) Review Your Use of Other Stimulants

Do a self-analysis of other stimulants you are taking like energy drinks or pop for example. Stimulants will only add to your caffeine levels so it is important that you take that into consideration.


Measure your grinds. Control the quantity of caffeine you are taking.

Follow these tips and keep your coffee sweats away for good!
