Does Coffee Wake You Up

Does Coffee Really Wake You Up in the Morning?

The alarm goes off, you stumble out of bed and walk toward the kitchen in a zombie state – you’re only focused on one thing: getting your morning cup of coffee. Countless people swear that they can only function after they’ve had a cup of Joe – but is it true? Does coffee really wake you up in the morning?

There are plenty of ways people drink coffee – whether it’s with cream and sugar, instant, plain or pressed, the options are endless. If you’re one of the millions of people who prefer to have a cup of coffee before anyone talks to you, there’s a good reason for it: caffeine. As the active ingredient in a cup of coffee, caffeine is responsible for getting the heart and oxygen rate up, which in turns fires up the rest of the body and brain to get cognitive thoughts more clear, as well as increase the flow of endorphins, epinephrine and cortisol. Caffeine is also known to block adenosine in the brain, which is responsible for that sleepy feeling we all get.

Of course, various factors go into how much a cup of coffee will do for you including how dark the roast is, how it is brewed and the size of your serving! The wonderful chemical composition of caffeine isn’t limited to coffee – it’s also found in soda, chocolate and tea, though the levels in coffee tend to be much higher depending on the type of brew. Without getting overly scientific, caffeine is fat and water soluble, meaning it doesn’t have to work too hard at getting from the bloodstream into the brain, thus giving you that much-needed jolt in the morning with your cup of coffee.

So, it goes to show that coffee does really wake you up in the morning – don’t start your day without it!
