Better Than A Double Espresso: 12 Things You Can Do To Relieve Stress & Gain Energy

The coffee you use to brew that cup of wake up juice can also impact the amount of caffeine you get per cup. As you know, there are many different species of coffee out there.

Each of these species contains different levels of caffeine. The most common in the world today is Arabica coffee. For example, Robusta beans have almost twice the amount of caffeine compared to Arabica beans. So, that means if you want more caffeine for a better buzz, look for Robusta beans in your local coffee shop. When you roast coffee beans, they lose water and expand in size. But something else happens during the roasting process as well. The longer you roast the coffee, the more caffeine is lost, at least when measured in scoops.

Essentially that means that light and medium roasts tend to have more caffeine when compared to the darker roasts. Sure that dark roast will have a much stronger flavor, but it will be weaker if you are looking for that caffeine buzz compared to lighter roasted coffee. Believe it or not, the size of your coffee grounds is also a factor.

Remember, water passes through the grinds extracting the flavors and, of course, the caffeine in the process. A finer ground coffee will have more surface area compared to coarse ground coffee allowing more caffeine to be extracted. This is one reason espresso has more caffeine since it is made with a fine ground coffee. Your water is a huge factor in determining not only how your coffee tastes but what is in it as well.

Cold brew coffees, for example, contain much less caffeine compared to hot brew coffee. How does that break down? Remember, a typical espresso gives you mg per cup. So, a double espresso would give you mg of caffeine. Since Robusta coffee contains almost double the amount of caffeine, you can bet you will have around mg of caffeine in that double espresso shot. Keep in mind that this is just an approximation. Some coffee has been designed to give you more caffeine than typical coffee even if you use a drip coffee maker.

Every process in our body is governed by a complex network of chemical signals. Two of the most important of these signals are hormones and neurotransmitters. Caffeine produces its effects on the body by altering the actions of just a few of these hormones and neurotransmitters.

First, caffeine binds itself to the adenosine receptors throughout the brain and nervous system. These receptors are used as an inhibitory neurotransmitter that suppresses the level of activity of the neurons that interact with it. Adenosine has been associated with promoting sleep and relaxation while also suppressing arousal. Since caffeine binds itself to these receptors, it prevents them from performing the action they are designed to do. Once it has suppressed adenosine function, it then starts a cascading affect within the body that alters the function of other hormones and neurotransmitters.

The most significant impact is its effect on our adrenals that produce and secrete the hormones epinephrine and cortisol. On top of that, caffeine also increases the circulation of serotonin in parts of the nervous system. This is why when you drink something with caffeine, your mood is elevated while at the same time your energy levels increase. When you drink caffeine, you will feel more alert and awake and even feel like you have more energy. This is why coffee has become the drink of choice in the mornings.

However, there are other effects that you should be aware of when you decide to drink coffee or any other drink that contains caffeine. Some of these side effects are:. Everyone reacts differently to caffeine, and some of us can handle more than others. The more often you drink it, the more your body will be able to process before some of the effects of caffeine become apparent.

Still, there are some instances where it is important to know that caffeine can make things worse, and not better.

For example, caffeine has been shown to make anxiety disorders and even bipolar disorders worse on patients suffering from these conditions. People with heart conditions must also use caution because of the effects that caffeine can have on your heart. These are just a few examples of conditions where people must use caffeine with caution or avoid it altogether.

While there are scientifically proven benefits, there are many negatives as well and it is important to be aware of these facts before you begin to consume more than your fair share of caffeine. Caffeine is addictive and over time your body will be accustomed to the levels of caffeine that you ingest. If you suddenly stop drinking caffeine, your body will be thrown off of its normal balance. Essentially, your body will be forced into a continuous replacement of hormones broken down by the continuous binding of caffeine to them. This leads to many of the withdrawal symptoms that you experience when you stop drinking caffeine including fatigue and even headaches.

Regularly using caffeine can also suppress iron absorption in your body as well as decrease the level of B-vitamins. For each performance test, there was no significant change indicating that energy drink had no effect on improving physical performance. The variability in the results of the above studies is mainly due to methodological differences. Variations in subjects, gender, dose of caffeine, ingredients of energy drinks, and type of placebo used contribute significantly to the inconsistency of the results.

Energy drinks may show positive beneficial effects on exercise performance in various sport activities. However, while energy drinks might benefit performance, possible detrimental health problems have been documented, particularly amongst children and adolescents. Various parts of the body are negatively affected by energy drink consumption. Considering this fact and the increasing popularity of these drinks, caution should be exercised while consuming energy drinks.

Overambitious marketing and non-scientific claims should be regulated by governments until independent studies confirm that that these products are safe.

Abstract Consumption of energy drinks has been increasing dramatically in the last two decades, particularly amongst adolescents and young adults. Introduction Energy drinks belong to a class of products, in liquid form, that typically contain caffeine, with or without other added dietary supplements. Potential adverse effects of energy drinks in relation to their ingredients Cardiovascular effect Several studies have shown an increase in heart rate and arterial blood pressure after energy drink consumption. Neurological and psychological effect Individuals usually develop symptoms of caffeine intoxication in doses equal to or above mg.

Gastrointestinal and metabolic effects Energy drinks usually contain large amounts of sugar ranging from 21 g to 34 g per oz. Renal effects The caffeine in energy drinks has been shown to enhance diuresis. Dental effects A study in Sweden showed a strong relationship between energy drinks and dental erosion. Beneficial effects The large amount of caffeine in energy drinks provides the consumer with the desirable effects of improved memory, increased alertness and elevated mood. Conclusion Energy drinks may show positive beneficial effects on exercise performance in various sport activities.
