"compared with iced coffee, hot coffee is the cooling artifact in summer!"

The temperature outside is close to 40 degrees Celsius, humid and muggy, and your sweat is even on the chair. At this time, you get up and make yourself a cup of steaming coffee.

Wait, there seems to be something wrong with such a scene! Believe that you in front of the screen, hot to sweat, want to stand under the air conditioner, dazzling ice drink bar.

In recent days, looking at all kinds of news reports about high temperature, I can't help but sigh: my life is given by ice drink, air conditioner and Wi-Fi! However, even when the somatosensory temperature exceeds 51 degrees Celsius, there are still people who are loyal to hot drinks.

A survey shows that coffee consumption has reached a new high in the past two decades, among which many daily coffee drinkers drink a cup of coffee with ice every day. In the hot summer, it is more common for handsome men and women on the street to hold a cup of iced coffee.

Have you ever wondered why iced coffee has become a must drink in summer?

Some friends may answer, in such hot weather, without a cup of iced coffee, I will melt!

Indeed, now that the North Pole is so hot that it can wear short sleeves, it is only natural to get rid of the temporary dryness and heat with ice drinks. At the very least, many people think that cold drinks quench thirst more than hot drinks.

Some friends will answer that iced coffee tastes better and is easier to taste than hot coffee.

On this point, we need to start with different perceptions of taste at different temperatures. In theory, the aroma is usually more obvious when the temperature is high. But why do you think iced coffee tastes good?

When we drink hot coffee, we can feel the change in the taste of coffee from high temperature to low temperature, while when tasting iced coffee, low temperature reduces the perception of bitterness and sweetness of taste buds, but magnifies the perception of sour taste.

In the eyes of some people, the act of buying iced coffee is simply robbing one's own wallet. Watching the barista pour ice into the cup crazily, just took two big sips, the coffee is about to bottom, looking at the heart will pull out the cold.

People may wonder why there are so many ice cubes. Is this really not a robbery? At this time, there will be some clever little brains, asking baristas to put less ice in the hope of getting more drinks.

The coffee workshop mentioned earlier that iced coffee reduces the taste buds' perception of bitterness because of its low temperature. What few people know is that when there is more ice, the drink cools faster and the ice melts more slowly, so the drink will be diluted more slowly.

In the eyes of many people, iced coffee is the artifact of relieving summer heat. However, some scientific studies have shown that hot drinks can really cause the cooling effect of the human body. On the contrary, ice drinks make people feel hotter.

Ollie Jay of the University of Sydney said in an interview with ABC that hot drinks can cool the body because of increased sweat, which takes away too much heat when sweat evaporates, bringing the experience of cooling. The more sweat flows out, the more sweat evaporates, which means more heat is taken away. In one experiment, researchers gave exercisers non-alcoholic drinks made from crushed ice, and the results showed that ice drinks made people feel hotter.

Whether it is iced coffee or hot coffee is a personal choice, since some people like hot coffee in summer, of course, some people like to drink iced coffee in winter.
