The Morning Debate: Tea Vs. Coffee Caffeine
When it comes to morning drinks, most people fall into one of two camps: tea or coffee. Even within each camp are subcategories and let me tell you, people take those very seriously.
Let's start with tea. There's black, green, white, and for those folks who don't need a morning boost, herbal tea! Then there's coffee, with its light, medium, and dark roasts, not to mention origin or the whole world of specialty drinks like lattes, cappuccinos, and plain Jane espresso.
Despite both being known for being a go-to morning beverage, tea and coffee are actually quite different when it comes to the impact they have on our bodies! So put on your favorite thinking cap and science coat and let's get this party started.
First off, What is Caffeine?
Caffeine is a natural stimulant commonly found in tea, coffee, and cacao plants. It helps you stay alert and fend off tiredness by stimulating your brain and central nervous system.
Balancing your caffeine intake can be a bit of a tightrope walk. You don’t want to drink too much and risk feeling jittery, but you also don’t want to have too little and miss out on its benefits. The key is paying attention to how much you're consuming and how it affects you personally.
Once you drink caffeine, it's quickly absorbed into your bloodstream from your gut. From there, it heads to your liver, where it's broken down into compounds that impact various organs. But its primary action is on your brain.
Caffeine works by blocking the effects of adenosine, a neurotransmitter that makes you feel relaxed and sleepy. As adenosine levels build up throughout the day, you start to feel more tired and ready for bed. Caffeine interferes with this process by connecting to adenosine receptors in the brain without activating them, which helps keep tiredness at bay.
It can also boost adrenaline levels in your blood and increase the activity of neurotransmitters like dopamine and norepinephrine. This combination helps you stay alert, focused, and energized. Because of its effects on the brain, caffeine is often classified as a psychoactive drug.
One cup of coffee can start to have an effect in as little as 20 minutes, with its full impact typically felt within an hour!
Tea Vs. Coffee
Now. We've all been there - enjoying a cup of coffee (or two) and suddenly feeling like we're on the verge of hyperdrive. What starts as a motivating energy can quickly turn into a mind and body that's racing a little too fast. On the other hand, tea, even a couple of cups, doesn't quite have the same effects.
Well, it all brews down to the science in the cup. Coffee's caffeine can spike cortisol (known as the stress hormone) levels, making us feel more on edge. On the other hand, compounds in tea, such as tannins, polyphenols, and L-theanine, team up with caffeine to provide a smoother, more sustained effect.
This means that instead of a quick burst, you get a longer, more controlled release of energy. Plus, the antioxidants in tea lead to a gentler increase in caffeine levels and longer periods of alertness without a crash. Some people have even reported feeling the effects of green tea hours later!
Fun Fact: Research shows that L-theanine (which is found in tea) has been shown to elevate levels of GABA, dopamine, and serotonin (all the happy hormones) making us feel calm and content. Who knew a drinking tea actually makes you happy?
One study found that both coffee and tea had similar effects on alertness and brainpower when consumed in equal amounts throughout the day. However, tea was found to be less disruptive to sleep than coffee. So, if you're sensitive to caffeine, a cup of tea might just be the better choice to make sure you aren't burning the midnight oil.
Though we are a tad biased, whether you're team tea or team coffee, either is a great ways to start the morning. So, no matter what you choose, may your morning drink be piping hot, brimming with joy, and prepared to energize you for the day ahead!
