Yes, it does have a good side and a bad side.
What Is Caffeine?
It is a stimulant. It is designed to perk you up and get your blood flowing faster. Blood vessels are dilated so you get more oxygen flowing. Caffeine is found in sodas, coffee, tea, chocolate and energy drinks.
Unfortunately there such a thing as too much of it.
Caffeine is an ingredient in many medications. We are not just talking about energy drinks or pills designed to keep you awake so you can cram for an exam or tend to a cranky baby.
Look at the ingredient list for headache medications. You will see caffeine listed there.
Caffeine can open blood vessels so that other medication can reach the site of pain more easily.
For someone suffering from a migraine headache, drinking a caffeinated soda or a cup of
coffee can provide quicker relief than a pill. It is not advised to drink a soda as your
main remedy, but it can take the edge off while your medication is starting to work.
Lowers risk of cardiovascular disease and diabetes.
Increases metabolic rate and is a source of antioxidants.
Let’s go back to those energy drinks. They don’t just keep you awake; they give you more energy. This is desirable for someone who has a lot to do and wants to get it done.
Remember that oxygen increase? As the blood vessels dilate, more blood can reach the brain and so can more oxygen. You can think more clearly from first thing in the morning.
That extra energy can assist with weight loss. Drinking energy drinks can help you get through a particularly tough workout. As the metabolism ramps up,
your body burns more calories to help you lose weight.
With the good also comes a bit of a downside.
While caffeine can do all of these things, using it too much can lead to some potential problems.
Caffeine is addictive. Ever notice that you can’t just have one cup of coffee? Some people have several cups. You may have started with one but you end up drinking more as your body gets used to the effects of one cup.
Too much can lead to jitters that can cause a lack of focus as the day wears on,
or even cause anxiety.
When that much caffeine is going through your system, stopping it can make you a bit woozy. Caffeine withdrawal can lead to dizziness, blurry vision and headache.
How ironic, since it can also stop a migraine.
High blood pressure is also a factor. Many medications that contain caffeine (such as cold medicine) are being changed to a different formulation for those who have a history of high blood pressure. The caffeine can raise normal blood pressure which makes them even more dangerous for someone who has a diagnosis of hypertension.
Are you a caffeine drinker? A little can be helpful but too much can backfire on you.
As for me... I'm having to back off because caffeine is also hard on the thyroid.
