The Effects Of Caffeine On Your Body

Many of us rely on a morning cup of coffee or a jolt of caffeine in the afternoon to help us get through the day. Caffeine is so widely available that the U.S. Food and Drug Administration , says about 80 percent of U.S. adults take some form of caffeine every day. But caffeine does so much more than just keeping you awake. Its a central nervous system stimulant that affects your body in numerous ways.

Knowing the symptoms of caffeine and its long-term effects on your body may make you think twice about having that fourth cup of coffee. Read on to learn more about these effects.

Caffeine provides no nutritional value on its own. Its tasteless, so you wont necessarily know if its in your food either. Even some medications may contain caffeine without your knowledge.

This ingredient almost always causes some symptoms. At a minimum, you may feel more energetic, but over time, too much caffeine may cause withdrawal symptoms. According to the Mayo Clinic, its safe for most healthy adults to consume up to 400 milligrams of caffeine per day. Keep in mind that a standard size cup of coffee is eight ounces. If youre using a mug or getting your fix at a coffee house, chances are youre drinking 16 ounces or more, so reading labels is important.

How Late Is Too Late To Drink Caffeine

We know how it works. We know about how long it can last. But, put together, what does this mean for someone who’s trying to have some caffeine without it affecting his or her sleep?

Unfortunately, this is a question with a fairly murky answer.

The short-and-sweet version is that most experts recommend setting your caffeine cutoff for 2 or 3 p.m.

While there’s plenty of research showing that caffeine disrupts sleep, only one study has examined how the timing of caffeine intake affects sleep. The study results showed that having caffeine even as early as six hours before bedtime can impact sleep, even if you don’t actually notice the disruption.

However, it’s also important to note that the study’s 12 participants were given the maximum daily dose of caffeine . This might not be a realistic representation of the average adult’s afternoon coffee consumption, but it may be a totally accurate representation of, say, a college student’s afternoon caffeine consumption.

Still, this study generally supports sticking with the 2 to 3 p.m. caffeine cutoff window experts suggest especially if you’re someone who starts winding down for bed around 9 p.m.

Ultimately, though, there’s probably no one-size-fits-all rule as to how late is too late when it comes to consuming caffeine.

The length of time your favorite caffeinated beverage might hang around in your system varies depending on:

Coffee Vs Energy Drinks For Teens

Aside from coffee and tea, soft drinks, and in particular, energy drinks, can include high levels of both caffeine and sugar. Cancer Councils research found that one in six Australian teenage boys drinks at least 52 litres of soft drink every year. Given some energy drinks can contain as much as 320mg of caffeine , this is a reason for concern.

The mix of caffeine and sugar can also affect mood, according to dietitian Susie Burrell. She says that after drinking an energy drink, teenagers can experience a down period about 30-40 minutes afterwards, which can lead to poor health choices. This correlates to research conducted by Cancer Council, which found teenagers who drink soft drinks and energy drinks are twice as likely to also be consuming more junk food.

Consuming too much caffeine can stop a teenager from getting adequate nutrition, says Gemma. Especially if they choose to drink coffee and soda rather than consuming more nutrient-dense foods, for example.

What Other Problems Can Happen

All The Ways Caffeine Affects Your Body in One Handy ...

Here are some other reasons to limit kids’ caffeine consumption:

  • Kids often drink caffeine contained in regular soft drinks. Kids who drink one or more sweetened soft drink per day are 60% more likely to be obese.
  • Caffeinated drinks often contain empty calories, and kids who fill up on them don’t get the vitamins and minerals they need from healthy sources. Too much soda can mean missing the calcium kids need from milk to build strong bones and teeth.
  • Too many sweetened caffeinated drinks could lead to dental cavities from the high sugar content and the erosion of tooth enamel from acidity.
  • Caffeine is a diuretic that causes the body to eliminate water , which may contribute to dehydration. It’s wise to avoid excessive caffeine in hot weather, when kids need to replace fluids lost through sweating.
  • Abruptly stopping caffeine may cause withdrawal symptoms , especially for those who consume a lot of it.
  • Caffeine can make heart problems or nervous disorders worse, and some kids might not know that they’re at risk.

Does Caffeine Sober You Up

People who have drunk too much alcohol often turn to coffee or an energy drink to sober them up.

However, caffeine does not sober a person up or make them fit to drive. It may make them more alert, but it does not reverse the poor judgment and other effects associated with alcohol.

In fact, it could be more dangerous because, without the drowsiness, a person is more likely to believe they are sober, which could lead to hazardous activities such as driving home or consuming more alcohol.

There is some controversy around energy drinks. They have been banned from a number of student campuses, because of reports of health problems and even fatalities.

The amount of caffeine in an energy drink depends on the brand and type.

While one 16-ounce Americano coffee can contain 225 mg of caffeine, the caffeine content of a 16-ounce can of energy drink until recently ranged from 160 mg to 357 mg.

Producers of the drink that contained 357 mg of caffeine have now lowered their caffeine content to 300 mg. It carries a health warning that it should not be consumed by children, those with heart problems, or those who may have an intolerance to caffeine.

Energy drinks contain not only caffeine but other plant-based stimulants, simple sugars or artificial sweeteners, and additives. A 16-ounce serving of one well-known energy drink would contain , or 1.75 ounces, or 5 teaspoons of sugar.

These high concentrations of caffeine and sugar could have a negative impact on the body.

What Does Caffeine Do to Your Body – the Pros and Cons

If you’re taking in too much caffeine, you may want to cut back. To avoid caffeine withdrawal, try cutting back slowly.

Replace caffeinated sodas and coffee with drinks without caffeine, like water, decaffeinated coffee, caffeine-free sodas, and caffeine-free teas.

Keep track of how many caffeinated drinks you have each day. Then, substitute one of these daily drinks with a decaf or caffeine-free alternative.

After a week or so, swap out another of your daily caffeine drinks with a decaf or caffeine-free option.

Do this for as many weeks as it takes to bring your daily caffeine intake to one caffeine drink a day, or even less.

How Caffeine Affects Your Nervous System

Increased Alertness

Caffeine is a stimulant. In the brain, it blocks the effects of a chemical called adenosine, which makes you feel sleepy. You then feel more alert and energetic, which is why many people drink coffee or tea to stay awake.

Sleep Cycle Changes

Caffeine may keep you awake even if you donât want it to. Levels of the hormone melatonin, which your body needs to fall asleep, decrease in the presence of caffeine. If you have trouble sleeping, you may want to limit your caffeine consumption in the afternoon and evening.

Feelings of Anxiety

The other downside is that caffeine may make you feel jittery or anxious, especially if you take in too much. If you have an existing anxiety or panic disorder, your doctor may advise you to avoid caffeine.

Increased Dopamine Levels

In other cases, caffeine can boost your mental well-being. It boosts the flow of dopamine, a brain chemical that makes you feel happy and engaged with the world around you. This may be why drinking a moderate amount of coffee has reduced some study participantsâ risk of depression and suicide.

Positive Impact on Memory and Cognition

Caffeine may even help you to think and remember better. Study participants who drink coffee have performed better on tests. Also, older people who consume caffeine may be less likely to develop Alzheimerâs disease and other age-related memory issues.

Addiction and Withdrawal

What Is Caffeine And How Does It Affect You

Caffeine is a central nervous system stimulant. When you drink it, you feel less tired and more alert. It helps you focus and can decrease headaches and migraines. Because caffeine absorbs into your bloodstream through your stomach, it takes one to two hours to reach its full effect.

If you overdo it, caffeine can also give you negative symptoms like heartburn and nausea. Thats why researchers suggest you keep your caffeine consumption under 400 milligrams per day. The average cup of coffee contains 95 milligrams of caffeine, so you can safely consume about four cups of caffeinated coffee every day.
