Many breastfeeding mothers wonder if it's OK to take caffeine. In fact, many nursing mothers just avoid caffeine in case it would keep their babies fussy, jittery and awake.
The answer is yes, you can take caffeine while breastfeeding, as long as you don't go over about 300 mg a day.
It's an important question because caffeine is in so many products, and taking coffee, tea, or soda is such a common ritual.
And breastfeeding mothers may be tempted to take caffeinated products because they are deprived of sleep by their newborns' odd sleep schedule.

So you like your coffee or tea, energy drinks, or caffeinated mints. But you're afraid too much caffeine is unwise.
In a meta-study published in the British Medical Journal, the researchers looked at the results of 218 other studies, most of the observational, to find the optimal amount of coffee consumption per day.
The result?
Three to four 8-ounce cups per daywill not only satisfy your caffeine cravings, but it results in some health benefits.

Scientists speculate that the caffeine lowers the body's sensitivity to insulin, meaning the hormone is not as effective as it once was. The cells don't absorb as much sugar from the blood after eating or drinking. To compensate, the body creates more insulin, which raises its level after your meals.
It's a double whammy because the body already uses insulin poorly, and blood sugar rises higher than it should. Caffeine might make this worse and make it hard to reduce blood sugar to healthy levels.
In time, the complications of diabetes, like heart disease or nerve damage, could become worse from the higher blood sugar induced by caffeine consumption.

That said, be careful you don't take caffeine so late that it prevents you from falling asleep. Sleep deprivation can have a big impact on mental health and can worsen depression. Sleep deprivation can also cause physical health problems, which can exacerbate depression.

Coffee beans are very stable chemically, even when roasted. That means coffee beans don't lose much caffeine in the roasting process.
However, light-roasted coffee beans are denser and heavier because they lose less water, so they have more caffeine per bean.
Dark-roasted coffee beans are less dense and weigh less. So you need to use a bigger volume of dark beans to get the same amount of caffeine in an equal volume of light-roasted beans.
But be cautioned, if you use a larger volume of dark beans, you are likely to have a very strong pot of coffee.

Speaking from experience, when you have severe symptoms of COVID, you may have trouble carrying out day-to-day tasks. For example, making yourself a cup of coffee or tea may be a task that you just are not up to.
Instead, you might buy some Viter Energy Mints, which require no preparation and have 40 mg of caffeine per mint. The mints also contain B vitamins, and mint to freshen the breath.

It seems caffeine may enhance memory and learning, but not if it is taken before the lesson is to be learned. Research from a few years ago says caffeine should be taken after that important business meeting, crucial college lecture or other knowledge-imparting event you need to recall.
Some studies show a benefit from caffeine on memory, some show none. Same with alcohol. But it seems scientists find with few exceptions that good diets promote healthy minds and bodies.

U.S. National Public Radio published a story titled "Caffeine for Sale: The Hidden Trade of the World's Favorite Stimulant" about how caffeine is removed from coffee beans and then where it goes after the decaf coffee is made.
Now there is a huge, worldwide trade in caffeine extracted from coffee beans. It is used in soda, energy drinks, medications and candies that have no natural caffeine content. And people wonder if synthetic caffeine is more dangerous than caffeine from natural sources. Scientists say there is no difference between the two.

Should you drink coffee at night? Apparently not. Between not getting enough sleep and drinking alcohol or doing drugs, many people are not getting enough sleep, and the sleep they do get is not optimal, researchers say.
A recent study says if you drink coffee or take caffeine at night that can interfere with sleep patterns by disrupting the circadian rhythm, or the body's internal clock that regulates when you sleep and stay awake.

What is the chemistry of coffee? Caffeine is the most famous chemical compound in coffee, but roasted coffee beans contain more than 1,000 other compounds. Some of these chemicals are noxious but still are not unhealthy because they are present in such low amounts.
You never hear anybody wake up and say, “I need a big dose of putrescine and dimethyl disulfide in my morning cup.”

Preparing for exams and tests in high school and college may be essential to getting an A, entering the university of your dreams or making the grade to go on for a master’s degree. Assuming you’ve studied the subject or subjects thoroughly, what should you do just one before an exam?
If it’s a big mid-term or final, an Advanced Placement or a Graduate Record Exam or other graduate school test, most people have to study the subjects thoroughly during the semester or school year or years. Attempting to learn all the material one hour before the very end is not a good strategy for a final exam or for a placement test.
