Can you imagine life without coffee? A cup of joe can instantly turn any groggy morning into a bearable one - but how does it affect your health?

Science has found that coffee can be good for one's health, as long as it is consumed in moderation. However, there are risks in drinking this drink, so here's everything you need to know about this wonderful drink:

Benefits

Coffee is an essential element for breakfast in most people's lives, because it can instantly awaken your still sleepy and groggy self.

Coffee makes your brain more alert and helps you focus on the tasks in front of you. It also has a high caffeine content, which provides that extra energy shake you need.

Caffeine is a psychoactive substance that stimulates the central nervous system, making you more alert. This vigilance or the effect of coffee usually lasts four hours - this natural stimulant can also be found in tea and soft drinks.

In addition to putting a bow in step, coffee can also help with migraine headaches, which is usually caused by an increase in blood flow due to enlarged blood vessels. Meanwhile, coffee narrows these vessels, a process called vasoconstriction , which in turn reduces blood flow.

It has also been found that coffee has a positive impact on your long-term health. It is said that this miracle drink helps reduce the risk of cardiovascular disease due to its content of antioxidants and micronutrients.

Coffee has niacin , a B vitamin that is beneficial for our digestive system and skin. It also has potassium, which regulates the heartbeat, and magnesium, which promotes strong bones.

Unfortunately, all these positive effects on our body should not be taken as a green light to indulge excessively with caffeine. Coffee can be beneficial in some ways, but how it affects our health depends on how we drink it.

You don't have to drink bitter black coffee every day to enjoy its benefits, but you should pay attention to how you flavor your drink. Cafes like Starbucks add liquid sweetener, which instantly accumulates calories.

Coffee also has different effects on people, but if you have a low tolerance for it, you may have a fast heartbeat, headache, irritability, insomnia, nervousness and upset stomach.

How much coffee should you drink then?

To avoid the risks mentioned, Mayo Clinic recommended drinking a maximum of four 8 ounces of coffee a day. However, if you are about 12-18 years old, the American Academy of Pediatrics has said that you should only take one cup of joe a day.

The general rule is to notice how coffee can make you feel.
