Everyone has different preferences for hot or cold coffee, but experts reveal the characteristics of each type of coffee.

Coffee is a popular beverage; some people prefer it hot, others cold, and sometimes the preference changes with the seasons.

Coffee can also be a healthy beverage if consumed in moderation. Several studies have shown that coffee offers numerous health benefits, from preventing chronic diseases to improving metabolism. Drinking the right amount of coffee, not excessively, can help reduce the risk of type 2 diabetes, Alzheimer's disease, heart disease, liver disease, and many other health problems.

Many people wonder whether iced or hot coffee offers more benefits.

What are the benefits of hot coffee?

According to Dr. Majid Basit, a cardiologist at Hermann Sugar Land Memorial Hospital in Texas (USA), drinking hot coffee enhances its aroma, and the fragrance of hot coffee can improve mood and reduce fatigue.

Jordan Karchner, a coffee expert, also suggests that smelling the aroma of hot coffee can help you feel more relaxed. A hot cup of coffee usually has a stronger aroma because the rising steam carries the fragrance away.

Many people also feel more relaxed when drinking a little hot coffee. Hot coffee has a stronger aroma, so this effect is greater than with iced coffee. Hot coffee also often makes people feel happier and warmer, especially when it's cold. Sometimes, a cup of hot coffee makes your meeting warmer, more intimate, and more caring than iced coffee.

What are the benefits of iced coffee?

Iced coffee also has certain benefits beyond the benefits of coffee; the ice cubes also offer advantages for those who enjoy it.

According to Dr. Eva Cwynar, an endocrinologist based in Beverly Hills, coffee is acidic and disrupts the gut microbiome, so sensitive individuals may experience heartburn and indigestion; iced coffee might be a more suitable option.

In that case, iced coffee is better than hot coffee because hot coffee may have a higher acidity level, causing discomfort.

Ice helps dilute the acidity in coffee, making it better for people who are prone to caffeine intoxication or those with stomach problems or poor digestion. Furthermore, iced coffee can provide a refreshing and cooling sensation.

3 things you should do when drinking coffee, which is like a miracle cure: 4 things to avoid to prevent harm to your health.

 3 healthy coffee drinking habits

Add a little sweetener.

Nutritionists share that adding too much sugar to coffee every day can lead to weight gain for some people, while for others it can cause a sudden increase in type 2 diabetes.

Add protein powder to your coffee.

Adding protein powder to your coffee can help boost your morning nutrient intake. Protein offers numerous health benefits, particularly in building muscle, reducing fat, and providing energy throughout the day.

Do not use disposable coffee cups.

Sometimes we don't have many choices, but by choosing not to use takeout cups we can avoid some harmful microplastics. Some coffee cups may contain microplastics that can leach into your coffee, harming hormone balance and overall health.

In addition, drinking black coffee is very good for your health. Black coffee is the best type for health because it contains all the healthy polyphenols and antioxidants without any other inflammatory compounds.

4 habits to avoid that could harm your health.

Drinking too much

When you drink coffee in moderation, it can be beneficial for brain health. But drinking too much does more harm than good. One study by scientists showed that drinking more than 6 cups of coffee a day increases the risk of reduced brain volume and the risk of dementia by 53%.

A healthy adult should consume 400 ml of caffeinated beverages per day, which is about 4 cups of coffee. Maintaining this amount or less will help you reap various benefits for your brain.

Drinking too late in the day

Coffee contains a lot of caffeine – a stimulant that lingers in the bloodstream for a long time. Coffee usually helps you stay alert and control lethargy in the morning and at midday. However, drinking coffee late in the day can make you restless and irritable.

According to experts, the average person takes about 5 hours to absorb caffeine, and it takes approximately 10 hours for the body to completely eliminate coffee from its system. That's why drinking coffee is detrimental to sleep.

Mistakes when drinking coffee

Coffee with too much sugar

A cup of coffee that's too sweet isn't a good choice for the brain. Excessive sugar consumption in adults is linked to poorer cognitive function. Additionally, chronically high blood sugar levels can lead to brain shrinkage, affecting the organ's functional connections and resulting in microvascular disease.

Stopping coffee abruptly

Stopping your coffee habit abruptly can also be harmful. Specifically, you may develop caffeine withdrawal headaches or difficulty concentrating. According to Livestrong, to avoid severe headaches and brain fog, you should reduce your caffeine intake gradually.

10 amazing benefits for people who have a habit of drinking coffee in the morning.

Scientists have discovered the amazing benefits of regularly drinking coffee after breakfast. This has been reported in mainstream media, and I'm sharing the details in the article below for everyone to know!

First effect: Reduces the risk of developing certain types of cancer.

All studies indicate that the high polyphenol content in coffee and caffeine can inhibit the growth of cancer cells. Coffee also stimulates bile production and reduces estrogen levels, lowering the risk of cancer, according to the scientific journal Scitech Daily.

Second benefit: Nourishes the brain, enhances concentration.

Many people drink coffee in the morning to kickstart their bodies. Studies show that the caffeine in coffee can stimulate the central nervous system, improving attention, reaction time, and memory.

In addition, caffeine can also boost the activity of nerve cells, helping people think and solve problems more effectively. Therefore, drinking a cup of coffee in the morning can help you handle many different tasks and work better.

Third benefit: Improves memory and slows down the aging process of the brain.

Caffeine is a stimulant that increases brain activity. Moderate amounts of caffeine can improve concentration, alertness, reaction time, as well as memory and learning abilities.

Fourth benefit: Weight control

Drinking coffee in the morning can also help boost your metabolism. The caffeine in coffee stimulates the release of adrenaline and norepinephrine, two hormones that help people burn fat and sugar more efficiently in a short time, thereby increasing energy levels.

Furthermore, research shows that caffeine can also increase the basal metabolic rate, meaning people consume more energy while at rest. Therefore, drinking coffee in the morning can help you burn calories and control your weight more easily.

Fifth benefit: Reduces the risk of developing type 2 diabetes.

Studies show that one cup of coffee can reduce the risk of developing diabetes by about 8%, and drinking more can reduce it by up to 30%. This is thanks to the magnesium and polyphenols in coffee, which help regulate glucose metabolism, according to Scitech Daily.

Sixth benefit: Good for the liver and reduces liver diseases.

According to a study by British scientists, people who drink coffee regularly have a lower risk of developing chronic liver disease. The researchers analyzed and compared data between 384,818 coffee drinkers and 109,767 non-coffee drinkers, monitoring their liver health over an 11-year period.

As a result, coffee drinkers had a 21% lower risk of chronic liver disease, a 20% lower risk of fatty liver disease, and a 49% lower risk of dying from chronic liver disease compared to non-coffee drinkers.

Seventh benefit: Helps you live longer.

A study conducted by the TH Chan School of Public Health, Harvard University (USA), has found that people who drink 3-5 cups of coffee a day are less likely to die prematurely, according to the British newspaper Express.

Eighth benefit: Helps improve mood, relieve stress, and prevent depression.

Besides providing energy, drinking coffee can also improve a person's mood. Caffeine stimulates the brain to release dopamine, a neurotransmitter that makes people feel happy.

Therefore, drinking a hot cup of coffee in the morning will help you feel happier and more relaxed.

Ninth benefit: Develops better social interaction.

Drinking coffee in the morning can also help promote social interaction. Drinking coffee in a cafe is a very common way to socialize, where people can mingle, share, and chat, making people feel more relaxed and comfortable, helping to relieve tension and stress.

In a coffee shop, people can make new friends and reconnect with old ones, making social activities more enjoyable and relaxed.

Although coffee has many benefits for you, you shouldn't overdo it. You should only drink it in moderation, aiming to reap the benefits for your body.

Benefit #10: Reduces the risk of Parkinson's disease.

Similar to Alzheimer's disease, Parkinson's disease also has no specific cure, making prevention even more important. Studies have shown that people who drink a lot of coffee have a 32-60% lower risk of developing Parkinson's disease, with caffeine in coffee being the main factor.

Parkinson's disease is the second most common neurodegenerative disease worldwide, after Alzheimer's. Parkinson's disease can cause nerve cells to die, thereby reducing nerve impulse transmission by decreasing dopamine levels in the brain.
