It also has harmful properties. The caffeine contained in the drink activates the activity of the heart, which causes blood vessels to narrow and blood pressure to increase. People who drink more than 6 cups per day have a 50% increased risk of heart attack.
Coffee stimulates the production of dopamine, and the nervous system is in an excited state. Therefore, insomnia and other sleep disorders may occur.

Effects of coffee
The effects of coffee taken in moderate doses (4 mg/kg caffeine per day) are mostly positive and, among other things, promote gastric activity, slow heart rate and help with bronchodilator dilation, improving allergic or asthmatic conditions.

The instant drink is easy to use and store. It has no sediment and dissolves not only in boiling water, but also in cool water.
The instant invigorating drink has fewer calories. But lovers of natural coffee claim that instant coffee cannot be compared to real coffee; the aroma and consistency are far from natural.
Many people think that an instant drink has less caffeine in its composition than a natural one, but this is far from the case. In fact, the amount of caffeine in natural coffee is an order of magnitude less. Because of this, doctors do not recommend drinking instant drinks often. It is better to replace it with grain.

Overcoming addiction is beneficial
Addiction to any substance is a risky and often harmful habit. Of course, the worse the substance, the more serious the problem. Drugs or illegal medicines are some of the worst examples. However, addiction to any substance is harmful to health. If you are addicted to coffee and rely on it every day, it is not healthy. Overcoming any addiction will give you more freedom and power over yourself.
For most people, caffeine is somewhat addictive, although some describe it as highly addictive. Regular and large amounts of coffee and caffeine consumption changes our brain chemistry, meaning we need more and more of the substance to achieve the results we want.
Giving up caffeine or coffee interrupts the cycle and frees us from the daily need to drink coffee to function properly.
Financial Savings
If you drink coffee regularly, you will also have to buy it. Coffee prices vary greatly, some are cheaper, others are very expensive. If you drink a lot of coffee, you will also spend a lot of money on it.

Especially all kinds of cafe visits in the city, regularly visited, drain your budget. Drinking coffee at home is, of course, cheaper, but more and more people like to drink coffee in the city. We come to a cafe for work, meet with friends, and at each such outlet there are regular expenses for coffee.
The cost of coffee and caffeine addiction can be significant, and you can save a lot of money by giving up coffee.
Better sleep
Of course, it is known that coffee and the caffeine it contains are a natural brain stimulant, but its consumption affects your sleep and the quality of your sleep. Even if you don't drink coffee before bed, it can affect your sleep.
Caffeine can significantly reduce the quantity and quality of sleep. Drinking coffee or energy drinks in the evening may interfere with sleep, as caffeine has a half-life of 4-6 hours. Even people who don't drink caffeine at 12 noon report better sleep quality after quitting caffeine.
People who stop drinking coffee often see improved sleep quality and feel more alert after sleep. This in turn means they have more energy throughout the day.
Best mood
Coffee affects your mood. For those who are accustomed to drinking coffee regularly, a lack of it at certain times can cause poor mood and well-being.

Caffeine changes your mood. Many people say they are more irritable until they drink their morning coffee, while others feel like they are sluggish when the caffeine stops working in the afternoon.
Eliminating coffee from your diet can offset these fluctuations—the ups and downs of your mood. Don't let any substances or bad habits affect your mood, emotions and the way you communicate with people. Stimulants should not have any power over you.
Reducing Anxiety
Research shows that coffee often increases anxiety and worry levels. This is because caffeine increases the amount of adrenaline in the body. Caffeine stimulates the adrenal glands.
Quitting coffee or caffeine may make you feel less anxious, especially if you are prone to anxiety problems.
Deciding to stop taking caffeine completely can be a great solution for people suffering from anxiety, especially if they begin to experience increased levels of anxiety and stress.
Less headaches
Caffeine is the main factor that causes headaches. Any changes in your daily caffeine intake can cause caffeine withdrawal headaches. Caffeine can also cause migraines.
Fewer trips to the toilet
Caffeinated drinks cause you to urinate more frequently and may even cause urinary incontinence in some people. Caffeine also stimulates the smooth muscles of the colon, which causes them to contract. This can be a problem during meetings, travel, or when there is no bathroom or its cleanliness is not conducive to use.
Eliminating coffee may reduce the need to use the toilet frequently, especially in the morning.
Healthy and white teeth
Drinking one cup of coffee a day is enough to notice changes in the color of your teeth over time. Depending on the coffee you drink, and especially the amount of sugar and milk you add to it, you may also experience dental problems. Especially if you drink all types of aromatic coffee with sweet additives.

Coffee, sour and sweet energy drinks, or sodas erode tooth enamel and can cause tooth decay. Eliminating these drinks results in whiter, healthier teeth.
Slender silhouette
Unless you drink your coffee black without any additives, caffeinated drinks tend to add empty calories to your diet that we don't really need. Many people sweeten their coffee and add milk to it.
Many experts say that sugary drinks are a component of the obesity epidemic that is plaguing our world.
A study conducted by the University of Victoria found that when caffeine is contained in a sweet drink, it causes people to consume more of that sweet drink compared to a decaffeinated sweet drink.
A cleaner natural environment

Caffeine addiction is an additional burden on our natural resources. Think about the number of mugs, bottles, jars and cups that need to be made to meet your needs.
Caffeine also showed up in city water supplies in the form of discarded coffee grounds. Quitting caffeine reduces your environmental footprint.
Caffeine will work again
Many people drink coffee every day because they need extra energy in the morning and afternoon.
However, after some time, our body gets used to a certain dose of caffeine, and coffee stops working for us. We stop seeing the energy benefits of drinking coffee.
Daily consumption of caffeine causes the human body to develop tolerance. After a longer period of regular caffeine consumption, the phenomenon of tachyphylaxis (tolerance) occurs, that is, a gradual weakening of the body's biological response. The same dose of caffeine causes a person to achieve a sense of normalcy rather than the euphoria they once felt.
Eliminating coffee restores caffeine tolerance, allowing it to actually work well in situations where it's really needed.
Less risk of drug interactions
Caffeine can interact with medications, causing them to not work properly. Avoiding caffeine reduces this risk.
No more seizures
Because caffeine is a natural stimulant, if we drink too much of it, it can cause our body to tremble. If you drink a lot of coffee and often suffer from involuntary cramps, you are likely experiencing one of the many side effects of taking too much caffeine.
This side effect of drinking coffee and caffeine can be annoying and even debilitating for some people. Quitting coffee can restore your balance.
Time savings and greater efficiency
What would you do with an extra hour every day? People who are addicted to coffee can easily waste time standing in line at cafes, taking coffee breaks at work, stopping at coffee shops, spending time cleaning and descaling the home machine, etc. The time saved can be use more productively.

Here are the main advantages and disadvantages of drinking coffee. You must decide for yourself whether drinking or stopping coffee is the best choice for you and your body.

With milk
Everyone knows that milk is a storehouse of vitamins, minerals and amino acids. Its beneficial properties have been known to mankind since ancient times. You can and should consume milk and dairy products at any age; they are perfectly digestible. When consumed, the pros and cons of coffee with milk boil down to the fact that there is only one minus, it should not be drunk by obese people.
Adding milk to a drink is very useful; the ingredients in the invigorating drink remove beneficial substances from the body, and milk replenishes them. Caffeine has an stimulating effect on the body, while milk has a calming and relaxing effect. A drink with milk has a positive effect on the body, increasing productivity, giving vigor and energy.
This drink is useful for people with liver disease, as well as those suffering from gastritis, atherosclerosis, and heart disease. Even doctors recommend drinking coffee, but only natural coffee diluted with milk.
Diabetic patients are advised to add only skim milk to their coffee. Elderly people who cannot cope with insomnia are recommended to drink weak coffee diluted with milk at night.

Decaf Coffee: Pros and Cons
The caffeine-free product is a healthy alternative to the classic drink. Since caffeine has a generally depressing effect on the body, causing addiction, anxiety, insomnia, and constant fatigue , it is better to drink the drink without it. All negative effects (increased blood pressure, increased heart rate, liver problems) are caused by the action of this substance.
The caffeine-free drink also has its downsides. So, it lowers blood pressure. This is due to the diuretic effect, which is neutralized in a regular product due to caffeine. But this same property can benefit patients suffering from high blood pressure.
Regardless of the preparation method, it will not be possible to completely remove caffeine; at least 1–2% will always remain.
Caffeine content should be considered before offering coffee to pregnant women or children.
In general, decaffeinated coffee does not differ in aroma and taste from the regular version of the drink. It does not have an invigorating effect, so it can be consumed before bed.

The benefit is to stimulate the nervous system and cardiac activity, thereby increasing performance and increasing blood pressure (which is good for hypotensive patients).
- Drinking coffee helps prevent type 2 diabetes. This is due to the content of chlorogenic and caffeic acids, as well as caffeine. These 3 substances inhibit the accumulation of amyloid protein, which contributes to the development of non-insulin-dependent diabetes mellitus.
- Coffee prevents the development of Parkinson's disease. Scientists noticed this connection in a practical way, noting that decaffeinated coffee does not prevent this disease (by the way, this effect was more pronounced in men).
- Prevention of stroke and cardiovascular diseases occurs due to the dilation of blood vessels in the brain and heart under the influence of caffeine.
- Substances contained in coffee increase gastric secretion - they increase the acidity of gastric juice. This property is useful for patients with gastritis with low acidity.
- Coffee is believed to help combat depression. Moreover, in women this effect is more pronounced.

What are the benefits of coffee?
The quality of the drink, its tonic effect and richness depend on how much caffeine it contains. The benefit of the substance is that it stimulates the functioning of the brain and strengthens memory. This is especially important for people over 50 years old. The beneficial properties also include the fact that coffee enhances performance, improves mood, and helps relieve stress.
In small quantities, Coffee strengthens potency and affects sexual desire.
In addition, it improves kidney function and has a positive effect on the functioning of the lungs, increases the content of fatty acids in the blood, which helps replenish wasted energy.
Coffee contains antioxidants. These substances slow down the processes of destruction and aging of body cells. They help keep you healthy and fresh. If coffee beans are roasted for a short time, the antioxidant content will only increase, while in over-roasted beans their volume will decrease as they disintegrate under the influence of high temperature.
The benefits of coffee are that when consumed without added sugar, tooth decay can be prevented. In addition, coffee has medicinal properties and is a prophylactic for the following diseases:
- diabetes;
- cirrhosis of the liver;
- cancer;
- Parkinson's and Alzheimer's diseases.
There is no end in sight to this dispute, since coffee, unlike energy drinks, is a natural product, therefore, it can be both beneficial and harmful. An analogy can be made with a tomato. This fruit is tasty and healthy, but in patients with gout it can cause an exacerbation of the disease, and if you eat several kilograms of tomatoes at a time, you can get poisoned. We will talk about coffee, the benefits and harm to human health in the presence of any diseases in the article.

Here's how the drink affects the male body:
- Ground coffee contains tannins, proteins, chlorogenic acid, minerals, polysaccharides, and fiber that are valuable for the body.

A short excursion into history
In ancient times, black coffee beans were not brewed, but rather eaten after being fried in oil. For several centuries in a row, the drink was not a drink at all, but was included in the list of expensive, gourmet dishes. The product was primarily valued for its powerful tonic and stimulating effect.
The whole world owes the appearance of this delicious drink to Arab merchants; it was they who first brought grains to Yemen. Of course, at that time no one thought about the question of whether drinking coffee was healthy, but simply enjoyed the taste and aroma. However, very soon clergy and healers began to talk about the benefits of coffee - coffee infusion helped overcome feelings of fatigue and cope with drowsiness.
Coffee makes you smarter
We all experience a certain physical-emotional slump at 2 p.m. You just ate too much for lunch, causing all your blood to go to your stomach instead of to your brain. Maybe you didn't get enough sleep last night, and your morning efforts are paying off.
In normal doses, caffeine stimulates the production of brain chemicals such as dopamine and norepinephrine. It lifts your mood, improves concentration, reduces reaction time and even improves memory. A person is less likely to suffer from depression with long-term caffeine consumption.
"Energy" drinks do not have to display caffeine content on the bottle, but many do contain more caffeine than regular drinks. They're also flavored with sugar, so try drinking straight black coffee instead of energy drinks.
Drinking a cup or two can be a good way to start the work day or compensate for fatigue; even if you drink coffee frequently and your body has developed some tolerance to caffeine. The half-life of caffeine is how long it takes for the kidneys and liver to reduce the amount of the substance in your blood by 50%; and this rate varies significantly among individuals. You may notice that the energizing effect wears off within an hour and a half or even ten, and you need to feel more energetic for 15 minutes or 2 hours.
