Energy Drink

Why do people drink soda? It’s probably because they think it tastes good.

But lately the soft drink market has been flooded with products that claim to have an effect beyond taste.

Energy drinks are one of these newcomers on the soft drink scene.

As their name implies, they claim to supply an energy boost.

They’re designed for students, athletes, and anyone else who wants an extra energy kick.

But there are worries about the true effect they can have on the body.

Energy drinks provide physical and mental stimulation over a short period of time.

But this is not because energy drinks contain various vitamins and health additives.

The real effect drinkers feel comes from the simple combination of sugar and caffeine.

A single energy drink typically contains more than twice as much caffeine as a can of soda.

Caffeine inhibits the production of adenosine, which promotes sleep, and increases adrenaline and dopamine, which can make a person feel alert.

The risks of consuming energy drinks are, therefore, roughly the same as those of drinking coffee.

Some people complain of an increase in their heart rate, feelings of anxiety, and trouble sleeping. And as caffeine has an addictive quality, energy drink consumers may find it difficult to limit themselves to the recommended maximum of 50ml per day as indicated on the product labels of many of the large energy drink manufacturers.

Unlike sports drinks that will assist in rehydrating the body during physical exercise,energy drinks actually act as a diuretic, thereby decreasing the amount of water retained in one’s body. It is easy to see, therefore, that consuming energy drinks during prolonged periods of exercise is potentially dangerous.

The potential hazards, however, go beyond risk of dehydration. Some energy drinks also contain ephedrine, a stimulant often used in diet pills that has been linked to heart problems, along with other ingredients whose effects are not yet fully understood.

When used in moderation, energy drinks can be a safe source of stimulation for people who are feeling listless. It is important, however, to understand exactly what we are putting into our bodies and the effects it may have.
