To Caffeine or Not to Caffeine. Evie D. (OMBS GRAD BLOG)


We all know caffeine to be a morning savor, or an afternoon pick-me-up but what if it is not holding anything that we are benefiting from apart from a short-lived caffeine hit. It can actually have the opposite effect altogether. We should live our lives with everything in moderation but that is easier said than done. The recommended intake of caffeine is as shown below:

Adult Less than 400 mg a day
Pregnant Women Less than 200 mg a day
Children / Adolescent Less than 2.5mg a day


To put this into some context a filter coffee is 140mg, tea is 75mg, a chocolate bar is 25-50mg and a fizzy drink is 40mg. Research shows that if you can keep to well within the recommended daily intake then you may experience some positive outcomes.

Caffeine is a stimulant this may work well for some people but for others, it could be affecting them in areas that you would not assume. If you suffer from anxiety or trouble sleeping at night caffeine will be doing you no favours this is due to a spike in blood pressure which leads to a shot of adrenalin causes heightened anxiety symptoms.

The half-life (the time it takes for an active substance in your body to be reduced by half) of caffeine is up to 9.5 hours. Therefore, it is advised that you should never drink caffeine before going to sleep as it will cause a restlessness night, this is the result of the half-life being so long that the stimulant effect will still be occurring internally even though consumption might have been hours ago.

If you have a more sensitive stomach or suffer from any stomach problems, then it is probably best that you steer away from caffeine intake.  You are more than likely aware of already caffeine is a diuretic this is another result of it being a stimulant just this time the stimulant is increasing your gut motility. If you are one that struggles in this area, then it is important to stay hydrated! This is because you will be losing a lot of unabsorbed nutrients. It is also important to stay hydrated as you do not want to develop any headaches or dehydration.
