How caffeine makes people "high"

Associate Professor of Clinical Medicine explained that our body actively secretes cortisol, a hormone that is very important in regulating the sleep/wake cycle.

This is how caffeine makes you high

When the body consumes caffeine, it stimulates the adrenal glands to produce cortisol. These substances increase blood pressure and speed up blood flow to deliver more nutrients such as glucose to cells as quickly as possible, so you will feel energetic and getting higher and higher. Cortisol is also known as the "stress hormone" to protect the body. Researchers also pointed out in a 2009 study that cortisol is also released when people feel stressed to help fight stress.

One choice: sugar or no sugar

For most people, the main reason for adding sugar to coffee is to reduce the bitterness of the coffee and make it easier to drink. Those who choose not to add sugar appreciate the aroma of the coffee itself. Adding sugar or milk will take away the original "fun" of drinking coffee.

Add sugar? No sugar?

A 2014 study on the effects of sugar and/or caffeine on behavioral abilities showed that people who regularly drink caffeinated beverages have a lower risk of developing certain neurological diseases. In addition, "caffeine + sugar" can enhance people's motivation to explore new things and increase their enthusiasm for participating in social activities.

Coffee plus sugar, power plus

In another study in 2016, a university researcher said that people who regularly drink sugary drinks also eat more refined foods with higher calories. The end result is excess calorie intake and weight gain.

Adding sugar to coffee may also make you fat

Coffee drinking knowledge: Compared with when to drink, how much to drink is more important?

From a broad perspective, the upper limit of caffeine intake for adults is 400mg per day. The associate professor said, "Different people have different sensitivities to caffeine." When some people find that their sensitivity to coffee has decreased, they will choose to increase their caffeine intake to get the same stimulating effect as before, unknowingly causing excessive caffeine intake.

The associate professor said, "Some studies have shown that moderate caffeine intake has certain health benefits." However, if the amount is not controlled, excessive caffeine intake is harmful to the human body.

Caffeine clearly has some positive effects on things like mood, memory, mental sharpness, and cognitive function, but like most things, too much can lead to ineffectiveness or impairment.

Professor warns: Some people experience palpitations, insomnia or anxiety after consuming too much caffeine. The effects of caffeine appear half an hour after ingestion and can last up to six hours.

The correct way to drink coffee

Is this how you should drink coffee? Drink coffee between meals, such as at 10 a.m. or 3 p.m., which will neither affect appetite nor sleep; 2-3 cups a day (200-300ml); do not add sugar or powdered sugar to coffee, as this will increase calories and energy, especially for girls who want to lose weight. Please pay attention to coffee products with less sugar, which usually only contain coffee (and milk).

In real life, some people are used to drinking coffee frequently because they sometimes feel tired without coffee. This article will tell you how people feel energetic after drinking coffee. As for whether to add sugar to coffee, it depends on how each friend drinks it. Moreover, research has found that drinking coffee frequently reduces the risk of neurological diseases and increases people's enthusiasm for socializing. However, if you add sugar to coffee frequently or drink too much coffee every day, it is easy to make people fat.
