Decaf coffee for hypersensitive & alergic to caffeine

There are over 2.25 billion cups of coffee consumed every day worldwide, and 10% of the world’s population is caffeine intolerant. They have to avoid or can’t have coffee because of their situation. So now the question arises:

Is there a coffee that doesn’t contain caffeine or a negligible amount of caffeine? Is there any coffee whose consumption doesn’t cause dehydration? Is there any coffee that hypersensitive and allergic people can have? The answer is YESDecaf coffee is the answer.

Let’s understand how decaf coffee is different from regular coffee.

Can I have decaf as I am hypersensitive and allergic to caffeine?


Our body considers caffeine as a harmful invader because of which it tries to fight them back with antibodies making one hypersensitive.

Hypersensitive people can’t have even small amounts of caffeine. Genes and your liver’s ability to metabolize caffeine are the major factors for hypersensitivity.

Moreover, there is some genetic evidence that some of us cannot process caffeine because they lack the genes responsible as the genes aren’t being expressed as they should be.

What happens when a hypersensitive person consumes caffeine?

The hypersensitivity leads to:

  • Rashes
  • Fast heartbeat
  • Headache
  • Jitters
  • Insomnia
  • Restlessness sweating
  • Swelling
  • Difficulty in catching breath, etc.

Soif you are hypersensitive to caffeine, you shouldn’t consume caffeine. Still, if you have questions, consider consulting your doctor. Moreover, if you don’t have hypersensitivity, it may develop later as adult’s metabolism isn’t as efficient as in childhood.

What else to avoid along with coffee?

You might not be aware, but we consume many consumables apart from coffee. Here are a few of them:

  • Cocoa beans and chocolate
  • Kola nut
  • Green tea
  • Guarana
  • Yerba mate drink
  • Frozen deserts
  • Soft drinks
  • Energy drinks
  • Chewing gums
  • Coffee flavoured food and ice creams
  • Vitamin supplements


As our body considers the caffeine as invaders, our body releases antibodies called immunoglobin E. These immunoglobin E prompts their cells to release histamine and try to get rid of molecules that our body considers harmful by mistake.

These molecules are known as allergens, leading to inflammation, causing the allergy.

The symptoms of sensitivity and allergy are almost the same, but allergy symptoms also include:

  • Hives
  • Itchy skin
  • Swelling of throat/tongue

If you aren’t sure if you have an allergy or not, get in touch with your doctor. Your doctor may perform a test to check if that’s an allergy or not by applying an allergen to your body.

Now the question is can you drink decaf coffee?

Yes, you can have decaf coffee even if you’re allergic though the normal intake capacity and tolerance might differ from individual to individual. And the less intake you’ll keep, the better it would be. 

Now, you’ve to observe how much it can take yourself and your body.

What to do when you’ve too much in a day?

Like alcohol hangover, even caffeine overdose takes time to get normal completely. Well, here is what else you can do to help yourself:

  • Don’t consume caffeine for that day.
  • Workout for a minimum of 150minutes/week.
  • Consume plenty of water as that would help you flush out caffeine quickly.
  • If you’ve diarrhoea, then probably water isn’t the only thing you’re losing. Along with water, you would be losing electrolytes which you can replenish by consuming an electrolyte replacement solution.
  • If your heartbeat isn’t rapid, you may consider walking to help you expend some energy.
  • In case you’re anxious or restless, then practice deep breathing and meditation.

How’s non-dehydrating coffee obtained?

Decaf coffee has close to 97% less caffeine from the regular coffee. So, if a regular cup of 236mg of coffee contains 70-140mg of caffeine, then a decaf coffee cup would’ve 7mg of caffeine.

The common decaffeination method involves chemical solvents, usually ethyl acetate/methylene chloride.

In the direct method, coffee beans are steamed. After that, they are repeatedly rinsed with the chemical to remove the caffeine content. On the other hand the indirect way, the chemical doesn’t come in contact with the beans but treats the caffeine-laden water in which the beans get soaked for hours.

After the caffeine is soaked, the coffee is given back its oils, aroma, and flavour. There are more methods to obtain decaf coffee.

Is decaf coffee a diuretic drink?

Diuretic drinks promote urine formation by the kidney, leading to increased water retention.

Coffee with caffeine is considered a diuretic drink but decaf coffee losses its caffeine properties. Hence, it isn’t a diuretic drink. A drink should contain at least 360mg of caffeine to act as a diuretic drink.

Is decaf addictive?

Yes, decaf is addictive if consumed regularly because even a small amount of caffeine can create dependency who rely on drinks in the morning or stay focused while working.

Coffee has a compound called Alkaloids which is also found in high addictive drugs like nicotine and morphine, which keep you hooked. Compared to regular coffee, decaf coffee is far less addictive as caffeine is far less than regular.
