What Does Too Much Caffeine Do To You

How Likely Is A Caffeine Overdose

Is Too Much Caffeine BAD For You?

A person might find consuming too much caffeine and experiencing side effects to be easy. However, a life-threatening overdose is rare, and a caffeine overdose as a cause of death even rarer.

In a 2018 review of scientific journal articles, researchers identified 92 reported deaths from caffeine overdose. This review included all journals since online databases began. The researchers believe that around one-third of these deaths are likely to be suicide.

In general, caffeine will begin to affect the body if there are more than 15 milligrams per liter in the blood. A concentration of 80 to 100 mg/L can be fatal.

Caffeine overdose is most likely to result from taking a dietary supplement or caffeine tablets rather than from drinking coffee, especially when people combine these products with energy drinks, sodas, or coffee. Supplements increase the risk due to having higher levels of caffeine than foods and drinks.

Unlike drinking coffee, or even taking supplements containing caffeine, using purified caffeine powder is highly dangerous and much more likely to cause an overdose.

The United States Food and Drug Administration warns that a teaspoon of powdered caffeine can be equivalent to 28 cups of coffee. It stresses that pure and highly concentrated caffeine products can have serious health consequences.

How Can I Cut Back On Caffeine Without Causing Unpleasant Side Effects

If youre used to drinking caffeine-containing beverages every day, and want to cut back, its best to do so gradually. Stopping abruptly can cause withdrawal symptoms such as headaches, anxiety, and nervousness. Unlike opioid or alcohol withdrawal, caffeine withdrawal is not considered dangerous, but it can be unpleasant. You may want to talk to your health care provider about how to cut back.

The American Academy of Pediatrics has taken a clear position on energy drinksthey have no place in the diets of children and adolescents.

A single energy drink could contain as much as 500 mg of caffeine, which is the equivalent of 14 cans of soda.

Despite the warning, approximately 50% of adolescents consume energy drinks and 31% consume caffeine on a regular basis. Some parents confuse energy drinks with sports drinks and many teens mistakenly believe energy drinks are healthy alternatives to soda.

Plus, energy drink companies create packaging and labels that appeal to a younger audience and frequently sponsor events that are likely to appeal to teens.

Energy drinks contain other substances that can be unhealthy for teens, including guarana, which is derived from a plant found in South America. Although it contains caffeine, its often not included in the caffeine tally.

Energy drinks can also contain amino acids, vitamins, and additives. The effects of these substances are largely unknown.

Caffeine: Are You Having Too Much?

In a world where nearly everyone is yearning for a more youthful appearance, giving up caffeine could be the greatest solution. Yes, it turns out that your coffee could be at least partially to blame for prematurely aged skin.

While you regularly depend on caffeine to keep you alert and energized, drinking too much of this stuff can have the opposite effect on your appearance. As soon as you start drinking it, caffeine begins cutting down on your skin’s production of collagen. “Collagen gives the skin tightness and elasticity that is responsible for keeping its youthful and vibrant appearance,” registered dietitian Trista Best explained to Health Digest.

When you have less collagen, you get more wrinkles. Obviously, this is expected as we age, but not when we’re simply relying on caffeine to keep us going. While you may not be ready to give up your lattes just yet, you may want to consider reducing your consumption. “Cutting back on coffee is one way to prevent this decrease in collagen and improve skin’s appearance,” Best said.
