The link between caffeine and anxiety is often controversial. Indeed, caffeine has the property of instantly elevating your mood by rushing dopamine in the body and making you feel happy. This instant rush can sometimes be hazardous to health as caffeine tends to make you addicted

Caffeine has the tendency to block adenosine A1 receptors, which boosts the consumption of caffeinated beverages. 

In an experiment, it was concluded that around 10 and 30 mg/kg doses of caffeine induces the concentration of dopamine and glutamate, thus taking you in a state of euphoria. 

Though it makes you feel good, excessive consumption of caffeine can also increase your stress and anxiety.

By the end of this article, you’ll get enough insights about the consumption of caffeine and it is important to know before you start overconsuming it. We have broken down all the biological facts about caffeine and how caffeine and anxiety can be linked.

How Excessive Consumption of Caffeine Causes stress?

Once the caffeine gets absorbed in the bloodstream, it directly passes to the brain where it blocks the compound called adenosine (it performs various physiological functions such as it helps in the regulation of sleep, controls the level of arousal and much more). 

It makes you feel drowsy and increases the activity in the brain which stimulates the CNS(Central Nervous System) and activates the stress response of the body. 

Then, certain chemical reactions take place by which it releases adrenaline and cortisol which triggers the body’s fight response making you feel stressed and jittered. 

Adrenaline triggers the fight response preparing your body for flight or fight which increases your heart rate and blood flow. 

How Does Caffeine Stimulate Anxiety and Make it worse?

When you’re juggling between multiple things in life, life can seem stressful and can cause you prolonged anxiety which may lead to anxiety disorder. There’s one drug that facilitates anxiety disorder in the body called “Caffeine”. 

People with underlying stress or anxiety should completely avoid consuming caffeine. As anxiety can cause you trouble sleeping, which may lead to fatigue and will make you more anxious, thus preventing you from falling asleep at night. 

Hence, people undergoing anxiety must avoid going into a caffeine-vicious cycle.

How many cups of Coffee is Excessive?

Caffeine affects everyone differently based on certain parameters like body weight, tolerance, gender, etc. 

Generally, around 400 mg of coffee is considered safe and healthy for adults with no medical issues, which is nearly about 4 cups of coffee. However, it depends on the rate of metabolism too. 

People who have a fast metabolic rate can metabolize coffee at a faster rate, tend to eliminate the amount of caffeine more quickly whereas people with a slow metabolism rate cannot break down caffeine easily and hence becomes anxious easily. Generally, younger people can metabolize caffeine quicker. 

In any case, avoid consuming more than 600mg of caffeine as it can be excessive and hard for the body to metabolize.

How to Analyse your Caffeine Threshold?

Since there’s a certain quantity of caffeine safe for adults, it’s crucial to determine your own threshold. The simplest way to find your threshold is to start observing the number of caffeinated beverages you have had in a day. 

How do you feel after consuming that many drinks? It’s important to be a little self-aware about your inner body. 

Start noticing after how many drinks you get the feeling of anxiety, become agitated (jittery), or want to rush into everything. Once you catch those feelings, perhaps you’ve reached the bar.
