Energy drinks are highly caffeinated beverages disguised in fruity flavours like orange, berry and fruit punch. They can also contain natural stimulants, such as ginseng and guarana. Energy drinks can range from 75 to 200 milligrams of caffeine, which is about 105.2 milligrams more than the average cup of coffee.
Energy drinks are bad for your heart
In those who consumed the energy drinks researchers saw spikes in blood pressure and norepinephrine levels doubled – norepinephrine is a stress hormone that prompts the “fight or flight” mode in the body. A rise in blood pressure as well as stress hormones increases heartbeats and breathing as a reaction to stress. If you’re in a stressful situation, these are normal responses, but if not it can have negative effects. Every time your heart is put under such stress it increases the risk of a future cardiovascular event.
Researchers believe the combination of sugar and caffeine is what sparks the heart’s response. Therefore, the research outcome is suggesting that you cut out energy drinks from your daily routine and look for natural, safer ways to boost energy when you’re in a slump.
Other dangers of energy drinks
The negative consequences of energy drinks aren’t limited to the heart. Energy drinks have also been found to lead to dehydration, work as a diuretic, interrupt sleep and promote excessive perspiration. These effects are harmful to people of all ages, especially seniors.
If a lack of energy is your concern and that is why you’re reaching for energy drinks, try water instead. It has been shown that even the slightest dehydration can cause a lack of concentration as well as fatigue. Staying hydrated is important, so replenishing your body with water will make for a more alert you and a healthier heart.
