Let’s start with how caffeine effects your body and your brain.
Researchers have found that caffeine has positive effects on your brain, body overall, and central nervous system.
Caffeine produces a feeling of pleasure and happiness….
Overall gives you positive vibes, this is because caffeine increases dopamine in the brain.
Increased dopamine (neurotransmitter) increases your heart rate which in turn delivers more oxygen to the muscles.
As research continues it finds that caffeine enables the brain to function better specifically by increasing your attention span due to caffeine reducing tiredness. Caffeine also reduces weight lane because it provides more energy to enable more exercise.
Being more active assists in breaking down carbohydrates and sugars quicker. And it also has been found that caffeine is a natural appetite suppressant, which helps reduce weight gain. Yay us!
But, how much caffeine a day is too much……. The recommended daily intake of coffee for a young adult should be less than 100mg. Some people are prone to side effects such as head aches, insomnia, fast heart beats, and muscle tremors that intake too much caffeine. Talk about too much of a good thing can sometimes be a bad thing.
Does caffeine last long? Before answering this, let me ask you, have you ever heard about half-life? This term describes the period of life of elements and compounds. How it works for caffeine is that half-life is approximately 5 hours. If you were to consume about 50 mg of caffeine in coffee, 5 hours late 25 of those mg would still be there. Caffeine is absorbed by the body fairly quickly. Within the first 45 minutes the caffeine intake is the highest. The fast absorption rate explains why you feel the effects of improved energy and mood enhancement.
There are different levels of caffeine. The levels can be dependent on a number of factors. Such as, the types of coffee beans the two main beans to make coffee. Arabica and Robusta, arabica beans are higher quality beans, but robusta beans have a higher level of caffeine. Another factor is roasting. Light beans and dark beans actually contain the same amount of caffeine in coffee per bean. The longer the roasting period means that the size of each dark roasted bean is lighter, light roast beans will have less caffeine than the dark roast. Lastly, serving size. Large doesn’t mean more caffeine, by the way. It all depends on the beans, and how the coffee is brewed.
Can we just agree coffee is a great way to get your caffeine intake? The pleasure, aroma, taste, and accessibility make it difficult to resist.
