Your afternoon coffee will cause insomnia.
Caffeine is a stimulant. However, the caffeine you consume in your post-lunch cup is processed through the liver at lightning speed and nearly all of it is flushed out of your body within 4 to 7 hours. So, if you drink your second cup at 3 p.m., it’s completely gone by bedtime, unless you’re really lame.
You should use boiling water on your grounds.
If the temperature of your water goes above 200 degrees Fahrenheit, the water will start to extract some of the bitter oils from coffee grounds and may even scorch them. You can Abe a contributing factor to the burnt taste of coffee in doing so.
Coffee dehydrates you.
Not true. Why exactly? Well, take a look at your cup of coffee. Notice the watery consistency? The amount of H2O in a cup makes up for the dehydrating effects of caffeine.
A cup of coffee will sober you up.
Not true. Caffeine can make an intoxicated person more alert, but a study by The American Psychological Association concluded that coffee does not reverse the negative cognitive impact of alcohol. It’s actually even worse for you, they report: “People who have consumed both alcohol and caffeine may feel awake and competent enough to handle potentially harmful situations, such as driving while intoxicated or placing themselves in dangerous social situations.”
Coffee Helps you lose weight.
Not exactly. The stimulating effects of caffeine can slightly increase your metabolism, but not enough to make a dent in your diet, especially in terms of long-term weight loss. Caffeine may reduce your desire to eat for a brief time, but there’s not enough evidence to show that long-term consumption aids weight loss.
Coffee stunts your growth.
This myth has been around forever. However, the belief that coffee does stunt your growth is nothing more than an old wives’ tale. It’s unclear how this myth got started, but there’s no scientific evidence supporting it.
Caffeine is highly addictive.
While there’s a little bit of truth to this one, it’s not as bad as some make it seem. Caffeine stimulates the central nervous system, which causes a very slight dependence, however the withdrawal effects last only a day or two and are a far cry from the withdrawal effects.
Coffee is bad for your health.
Consuming a moderate amount of caffeine on the daily isn’t going to hurt you. If you have high blood pressure, you could potentially experience a temporary rise in heart rate, but there is no link to caffeine and high cholesterol, or cardiovascular disease.
Pregnant women shouldn’t drink coffee.
This is a personal call. It is advised that pregnant women should limit their caffeine intake to only about one cup of coffee. Caffeine can pass through the placenta and reach the baby, but there are no concrete studies saying it’s harmful.
Decaf means no caffeine.
Despite being misleadingly named, decaf coffee actually does have a little bit of caffeine in it. According to USDA regulations, decaf coffee needs to be 97% caffeine free. So, that extra 3% probably won’t affect you too much, but it’s still there.
