The Effects of Caffeine On Your Body

We also have a detailed article on how much caffeine is in a cup of coffee, in case if you want to check that out.

The Effects Of Caffeine On Your Body

There is a reason people consume coffee on a daily basis while they vary the diet they have. In fact, this is because there have quite a lot of caffeine effects on your body. Let us check out what it does below.

1. It May Cause Anxiety- (What Is Caffeine Anxiety?)

As you may already know, our emotions are nothing but chemical reactions. Consider the chemicals that are present in caffeine and the ones present in your body.

Apparently, we have these two hormones epinephrine and cortisol in our body that are responsible for a ‘flight or fight’ response.

What epinephrine does is it increases your response to danger by increasing your heart and respiration rates. As a result, you are more aware and you react more.

And, what caffeine does is, it increases the epinephrine in your body making the fight or flight feeling more aggressive. It is not always life or death situations that can stimulate such anxious states.

In fact, you may be waiting to give a presentation where your reputation is concerned.

Caffeine intake before such an event that can make you nervous can really increase the anxiety. So, this is how it can cause anxiety.

2. Wakes You Up So Well That It Can Also Cause Insomnia.

This is an obvious effect as you do not see millions of people running with coffee in their hands in the morning for no reason.

Apparently, caffeine boosts up your nervous system by operating on the hormonal and neurotransmitter levels. There is another hormone in our bodies called adenosine.

Adenosine receptors are what helps you sleep, relax, and not feel aroused. When caffeine attaches itself to adenosine receptors, it inhibits its functions to some extent. SO, you do not feel sleepy but get active.

You do not relax and may get nervous. While this is great for daily life, too much caffeine can cause trouble. You will feel too nervous, too active and it may even lead to insomnia.

3. Elevates Your Mood.

Coffee dates exist for a reason, don’t they? While it is a light beverage to be consuming, it does have deeper effects.

Apparently, caffeine increases the operation of serotonin. And, Serotonin is something that is responsible for our mood, good mood.  

The more it reaches parts of our nervous system, the better we feel. So, to feel not only awake but also good, caffeine intake in reasonable amounts is a great idea.

4. May Decrease Iron Absorption.  

While Caffeine has its many benefits, it is not always an angel and certainly not for everyone. In fact, it can limit your body’s ability to absorb iron and also reduce the Vitamin B.

However, it does not affect everyone in the same way and it will only cause trouble when consumed in more than normal levels.

Apparently, people suffering from iron deficiency may end up having anemia if they consume too much coffee.

5. It Can Cause Nausea and Diarrhea.

You do not always consume caffeine with water. In fact, most of the time people consume it by mixing it with milk. And, milk is a laxative.

It somewhat helps the laxative action more. Therefore, when people consume more coffee, they have often had to respond to nature’s call immediately.

Other than that, it can often cause nausea as it dehydrates your body a bit when consumed.

All its effects lead to the question

Is Caffeine Good or Bad for Your Health?

Is Caffeine Good or Bad for Your Health

You see caffeine affects your health in many different ways- some good and some bad. Apparently, how it affects your body depends on your body as well. Some people can tolerate it while others cannot at all.
