7 ways caffeine affects your health and body

For those who need to stay awake or get an instant energy boost, caffeine has been the go-to stimulant.

Found in various sources like coffee, cocoa beans, tea plant, nectar and even in totally unexpected foods like ice cream and yogurt, caffeine is a natural substance that’s considered a “moderately effective alerting agent.” [1]

This means that caffeine promotes alertness and keeps you awake.

But it also does so much more than that!

Aside from helping you wake up and get out of sluggish zone, here are 7 ways caffeine affects your health and body:


Energy boost

First things first. To understand how caffeine helps you get out of bed, you need to know what adenosine is.

As the body metabolizes ATP, a high-energy molecule used for a constant supply of energy, it liberates adenosine, which is the reason for why you feel sleepy. As the sleep-inducing molecule in the body, adenosine binds to receptors in the brain, leading to a slowdown in nerve cell activity and drowsiness.

Caffeine enters the picture when it binds into adenosine receptors. Because it looks like adenosine, caffeine gets mistaken as such and binds into the receptors. It then blocks and prevents actual adenosine from linking to receptors.

Voila – instead of slowing down nerve cell activities, caffeine does the complete opposite and stimulates you! [2]

Mental performance

Caffeine can help you become more attentive and laser-focused. According to the European Food Safety Authority (EFSA), there’s a direct causal relationship between 75mg of caffeine, which is equivalent to a tall cup of coffee, and a higher level of attention and alertness. [3]

It can also enhance cognitive functions such as attentiveness, efficient learning, enhanced long-term memory, planning and concentration.

Sports performance

Athletes also enjoy the benefits of caffeine. In fact, 75% of the world’s elite athletes take advantage of caffeine’s performance-enhancing properties.

Caffeine helps athletes achieve optimal sports performance by delaying feelings of fatigue and preventing sleep. [4] This is especially helpful for those who need to cope with a different time zone and battle jetlag before gun start!

Also, a Men’s Health article reports that caffeine enhances “short-term, intense activities and improves endurance athletes’ times by up to 3 percent—a margin that could certainly matter in Olympic-caliber competition.” [5]

Caffeine can turn you into a walking ball of sunshine. It improves your mood and eases the risk of depression.

According to a study, a tall cup of coffee containing 75 mg of caffeine can result in a “pattern of sustained improvement of mood over the day.” It can increase alertness and well-being, help concentration, improve mood and limit depression. [6]

Also, a report by the Harvard School of Public Health says that caffeine can make you a generally positive person. This is because of the substances that activate the reward systems of the brain, thus mimicking the effects of a mild antidepressant. [7]

To those trying to lose or watch their weight, here’s a big heads up –

Caffeine can actually boost your metabolism!

  1. Caffeine has substances that boost metabolism, namely theobromine, theophylline and chlorogenic acid. These substances help your body slow down the absorption of sugars and carbohydrates.
  2. Caffeine helps burn fat. Research shows that drinking coffee before a workout helps burn more fat than going without it. [8] Caffeine increases energy levels during physical exercise and leads to increased endurance. People who drink coffee before hitting the gym find themselves working harder and longer, burning more calories.
  3. Caffeine increases metabolic rate. Studies show that caffeine can increase Resting Metabolic Rate (RMR) by 3–11%. [9] This simply means that our favorite stimulant helps our body burn calories more efficiently and lose weight faster.

Not everything’s rainbows and butterflies with the stimulant in question.

Unfortunately, caffeine can also have a negative interaction with certain medications.

A report by the New York Times says that caffeine can influence the effectivity of some medications and hinder them from working properly. [10

Some interactions may range from mild to moderate, all the way to lethal. If you are taking medications and craving for a cup of joe, it’s best to consult a medical professional first to find out whether it’s safe to mix your meds with caffeine.
