Let’s delve into the age-old debate: Is coffee your trusty companion or sneaky adversary? Well, turns out, it might just be neither!
Caffeine, the superstar stimulant, holds the title for the most widely consumed psychoactive drug in the world. It has been a long-time favorite fuel for humans across the globe, found in an array of delightful sources like coffee, espresso, tea, matcha, Yerba Mate, energy drinks, chocolate, and soda.
Now, what does this magical bean juice do to our bodies, you ask? Brace yourself for a rollercoaster ride of effects. Here are some of the most common negative side effectss:
- increased heart rate and blood pressure
- increased respiration
- sweating & dehydration
- tremors
- increased menstrual cramping
- anxiety and irritability
- insomnia
- diarrhea
- acid reflux/heartburn
- frequent urination
- dizziness and headaches
- rapid heartbeat (palpitations)
- restlessness and excitability
The effects of caffeine vary from person to person depending on the amount of caffeine consumed, the person’s sensitivity to caffeine, and their overall health. Moderate caffeine consumption of up to 400 milligrams per day is considered safe for most people. However, for some people like myself, even small amounts of caffeine can cause negative side effects.
Before discussing its effects further, I want to quickly breakdown the mechanisms of its actions:
- Blockade of adenosine receptors: Caffeine blocks the effects of adenosine, a neurotransmitter that makes you feel tired. This makes you feel more alert and awake.
- Increased dopamine release: Caffeine increases the release of dopamine, a neurotransmitter that is associated with pleasure and motivation. This can lead to a feeling of increased energy and focus.
- Increased neuronal activity: It activates noradrenaline neurons and seems to affect the local release of dopamine. It can also increase your body’s secretion of cortisol, the infamous “stress hormone.” This can lead to a number of effects, including increased heart rate and blood pressure, increased respiration, dilated pupils, increased sweating, tremors, anxiety, and insomnia.
- Norepinephrine release: Caffeine increases the release of norepinephrine, a neurotransmitter that is associated with alertness and attention.
- Phosphodiesterase inhibition: Caffeine inhibits phosphodiesterase, an enzyme that breaks down cyclic AMP. This leads to an increase in cyclic AMP, which has a number of effects, including increased alertness and energy.
- Calcium mobilization: At high doses, caffeine mobilizes calcium from intracellular stores. This can lead to a number of effects, including increased heart rate and blood pressure.
- GABA antagonism: Caffeine antagonizes GABA, an inhibitory neurotransmitter. This can lead to increased alertness and energy.
Thanks to these mechanisms and some other cool features of caffeine, there are also plenty of benefits we gain from caffeine:
- decreased risk of depression
- decreased risk of suicide
- increased memory retention
- increased athletic performance
- protective against Alzheimer’s and Dementia
So what gives? IS it good or bad? Ultimately, your personal relationship with coffee determines whether its a friend or foe.
If you suffer from anxiety, panic disorder, insomnia, ibs-d, acid reflux, hypotension, diabetes, chronic fatigue or you are pregnant – it might be time to rethink that caffeine fix. With a half-life of about 5 hours, caffeine can linger in your system, wreaking havoc on your body’s natural equilibrium.
So if you drank 240mg at 9am, then by 2pm you may still have 120mg in your system. Which means its still blocking or triggering different chemical reactions and hormone secretions that your body naturally wouldn’t.
For the go-getters, early risers, and everyday hustlers, moderate caffeine intake can be your ally in navigating the daily grind. As someone who juggles IBS, panic attacks, and the occasional bout of insomnia, I’ve learned to sip strategically, opting for decaf or matcha on well-rested days and saving the espresso for those marathon work sessions.
And for those die-hard coffee enthusiasts who can’t fathom a caffeine-free day, here’s a thought: Try mixing in a decaf or “half-caf” treat once in a while. Not only will it give you a fresh perspective on your coffee habits, but it might just make that caffeine kick feel all the more potent when you do indulge.
So, whether you’re a devoted java junkie or a casual sipper, your relationship with coffee ultimately dictates whether it’s a friend or foe. Embrace the balance, sip consciously, and remember – a well-crafted coffee ritual can be the perfect start to your day or a sweet reward to savor. Cheers to finding your perfect brew!
How do I moderate my caffeine intake? As someone who suffers from IBS, Panic Disorder and menstrual Insomnia, I drink 1 shot of espresso (70mg of caffeine) instead of coffee(130-150mg of caffeine). This cuts my caffeine intake in half! Additionally, if I slept 8-9 hours, I’m probably going to start my day with water, a decaf cup of coffee or Matcha. Doing this has kept my panic attacks dormant, prevents my gut from having flare ups and my sleep is far more regular.
