More and more people are starting to drink coffee, but there are many misconceptions about coffee. Let's take a look at the truth:
Misconception 1: Coffee is addictive
This statement has some truth to it, but it depends on how you define "addiction." For the central nervous system, coffee is a stimulant. Regular consumption can lead to mild physical dependence. However, coffee does not harm physical or mental health like other addictive substances. If you suddenly stop drinking coffee, you might experience symptoms like headaches, fatigue, anxiety, irritability, depression, and difficulty concentrating, but these symptoms usually only last for a few days.
Misconception 2: Coffee causes insomnia
The body absorbs caffeine quickly and also metabolizes it rapidly. Caffeine has a short half-life. Generally, it takes only 4 to 5 hours for the body to eliminate half of the caffeine, and after 8 to 10 hours, 75% of it is gone. Therefore, if a person drinks coffee in the morning, their sleep at night should not be affected. However, drinking coffee in the evening might impact sleep. Most people can drink coffee 6 hours before bed without it affecting their sleep. But, based on individual differences in metabolism and sensitivity, as well as the amount consumed, the effects can vary. Highly sensitive individuals may not only experience insomnia but also nervousness and gastrointestinal discomfort after drinking coffee.
Misconception 3: Coffee increases the risk of osteoporosis, heart disease, and cancer
Generally, 300 milligrams of caffeine or 3 cups of coffee per day is harmless to health. However, for sensitive individuals, such as those with high blood pressure or the elderly, the situation might be different. Consider the following facts:
Osteoporosis and caffeine: High caffeine intake can increase the excretion of magnesium and calcium in urine. However, recent research has found that adding a spoonful of milk to your coffee can prevent any negative effects on bone density. Nevertheless, coffee can contribute to hip fractures in the elderly because they are more sensitive to its effects. So, if you want to drink coffee, discuss with your doctor whether you can reduce your daily caffeine intake to 300 milligrams or less. Cardiovascular disease and caffeine: Sensitive individuals may experience a slight increase in heart rate and blood pressure due to caffeine. However, studies have shown that caffeine does not cause irregular heartbeats, elevated cholesterol levels, or an increased risk of cardiovascular disease. If you have high blood pressure, consult your doctor to determine a suitable coffee intake level.
Cancer and coffee: Research indicates that coffee does not cause cancer and may even have a protective effect against certain types of cancer.
Misconception 4: Women who want to get pregnant should not drink coffee
Studies have shown that low to moderate coffee consumption is not associated with pregnancy, miscarriage, birth defects, premature birth, or low birth weight. However, for women who are already pregnant or planning to become pregnant, it is best not to exceed 200 milligrams of caffeine per day, as high amounts can increase the risk of miscarriage.
Misconception 5: Coffee is dehydrating
Coffee may make you feel the urge to urinate, but this fluid loss is compensated for. Although coffee has a mild diuretic effect, research shows that it does not cause dehydration.
Misconception 6: Coffee is harmful to children
Surveys indicate that it is safe for children aged 6 to 9 to consume 22 milligrams of caffeine per day. However, many children are sensitive to caffeine and may experience temporary anxiety or irritability. Moreover, most of the caffeine children consume comes from carbonated drinks, energy drinks, or sugary tea. These beverages are high in sugar and can lead to obesity in children. Therefore, even if caffeine itself is not harmful, caffeinated beverages are not good for children.
Misconception 7: Coffee sobers you up
People stubbornly believe that coffee can sober them up, so they drink it with alcohol. However, studies show that their reaction time and judgment are actually impaired. Research has found that college students who drink alcohol and coffee together are more likely to be involved in car accidents.
Misconception 8: Coffee has no health benefits
In fact, the potential benefits of coffee are quite interesting. Anyone who regularly drinks coffee will tell you that it can increase alertness, improve concentration, boost energy, clear the mind, and provide a sense of social belonging. Scientific research has also confirmed these findings. Some studies even suggest that coffee can slow the decline in cognitive abilities. Additionally, coffee's anti-inflammatory effects can strengthen the immune system and alleviate allergic reactions. Other research indicates that coffee may lower the risk of Alzheimer's disease, liver disease, intestinal diseases, and type 2 diabetes. However, remember not to consume caffeine in excessive amounts.
