Your favourite cup of coffee keeps you going for the day! Majority of the people include coffee as it helps keep their mind stay alert and focused to perform better. But what if you become intolerant to caffeine? Read on to know how it happens and what can be done to overcome it.

“Caffeine” is a stimulant, responsible for keeping us alert and naturally found in beverages like coffee and tea. On the other hand, caffeine extract is added to energy drinks, sweetened beverages and even soda to provide similar effects.

Caffeine acts by releasing chemicals in your brain responsible for better mood, to combat fatigue, and enhance focus, especially during mid-afternoon crash. However, it’s been observed that caffeine’s stimulatory effects become less noticeable over time, that’s because your body becomes tolerant or less responsive to its effects. Why does this happen? It is because the adenosine receptors become less sensitive to caffeine with repeated exposure. Thus, this decrease in caffeine effect happens as you become more tolerant over a while. Therefore, it will have any impact on your exercise performance, mental alertness and performance.

So now, how to overcome intolerance?

Simply, by decreasing the amount of caffeine intake, consuming it less often than you normally do. Although you can also increase the number of cups you consume, it is not advisable as there is a safe level consumption of caffeine, which should not be crossed.

Initially, you may face caffeine withdrawal symptoms, like headaches, mood swings, tiredness, sleepiness etc. But with time, you will overcome intolerance as the symptoms will subdue.
