Effects of Caffeine on the Brain

In some parts of the world, coffee is seen as liquid gold. It is the high-performance brain fuel most of the Western world relies on to get through the day. The active ingredient in coffee that makes it so valuable? Caffeine. 80% of the US population consumes caffeine every day. It is a psychoactive “drug” with energy inducing properties and is the most commonly used drug worldwide but what are the real effects of caffeine on your brain?

There is also a negative tolerance to drinking too much coffee, along with developing a greater tolerance to the effects of caffeine. Scientists suggest that adults should not consume more than 400mg of caffeine a day. It is similar to about 4 cups of coffee. Once you recommend consuming caffeine, you will start feeling unwell. Dehydration, headache, palpitations, nervousness, and dizziness may all occur.

Once you start consuming too much caffeine per day, your body can also start experiencing caffeine withdrawal. Caffeine deficiency can cause headaches, fatigue, irritability, and nausea. The main thing to remember about coffee is that, like everything else, it is best consumed. We recommend sticking to a daily intake of 4 cups or less.

If you start feeling tired, why not switch to sparkling water? One of the main causes of exhaustion is dehydration. As a result, by hydrating properly, you ensure that you do not just dehydrate and look for a quick caffeine fix. For adults, three to five cups of coffee a day, or up to 400 milligrams of caffeine is safe.

  • Research shows that kids who consume one or more artificially sweetened soft drinks daily are at a 6% higher risk of becoming obese.
  • Drinking caffeinated beverages with added sugar can cause cavities.
  • Caffeinated drinks are full of empty calories, and kids who drink them regularly miss out on the crucial vitamins and minerals they get from healthy food.
  • Being a diuretic, caffeine causes the elimination of water from the body, and thus dehydration. In warm climates when kids sweat a lot it is best to avoid caffeine to prevent dehydration.
  • Caffeine can make heart or nerve disorders worse, and kids might not even know if they are at risk of such disorders.
  • Drastic reduction in caffeine intake can cause withdrawal symptoms such as irritability, headaches, and muscle aches.

They should also be made aware of the fact that caffeine does not provide any nutrients like protein or calcium, and we do not need it to stay healthy.
