Caffeine. Sometimes, it’s a love-hate relationship. It keeps us awake when we need to (read: all-nighters), but it can also keep us more alert than we’re supposed to.
For something we consume regularly, caffeine tends to consume us back. We enjoy it so much to have one, two, three cups of our favorite caffeinated drink, only to realize the consequence when that 1 AM moment hits.
Caffeine can be a much-needed boost – that’s common knowledge – but we’ve never really paid much attention to how it works.
That’s what this article’s for. We’re going to dive deep into caffeine and how it affects sleep.
Coffee, tea or (caffeine) mints.
So, which of these have you popped or downed today?
These products all contain varying amounts of caffeine, alongside others you wouldn't have thought to contain it. Ice cream, frozen yogurt, breakfast cereals, pudding, pain medications … even cocoa butter lotion apparently all have it! 
Do you like most (or all) of these products? Then you must be wondering how much caffeine you take in daily.
We've got you covered.

Feeling antsy and hyperactive, being impulsive, and having short attention span are telltale signs of Attention Deficit Hyperactivity Disorder or ADHD.
ADHD is usually thought of as a disorder in children, but people can have it even as an adult.
You might think the last thing you should take is caffeine, which is known to boost energy. But it may be just what the doctor could prescribe.
Some of our favorite athletes are just like us – they have their everyday caffeine regimenand love it.
But did you know that some athletes don’t just have it as part of their morning routine; they also use it to boost sports performance?
In fact, three-fourths of the world’s elite athletes take advantage of caffeine’s performance-enhancing properties.
But have athletes always been allowed to drink coffee and other products with caffeine in them, especially right before the sport?
If so, how much are they allowed to consume?
Pregnant ladies may be going through A LOT of changes (such an understatement, we know).
This is probably true not just with their body (physical and physiological), but also in their diet. There’s a lot of foods and beverages to avoid during pregnancy, which is a tall order for a lot of people! 
And for many, quitting caffeine is the toughest.
But is getting a caffeine fix really bad for pregnant women?
We’re going to try to answer this million-dollar question by putting together the various research and studies we’ve found on the topic and try to help you ladies come up with not just an answer, but a solution.
Migraines can get so painful that people who suffer from them are often only able to do little, if none at all.
Migraine headaches are very common and are a major health problem globally. In the United States alone, there are about 38 million migraine patients - adults and children alike . That's about 1 in 4 households with people prone to migraines.
But there’s a silver lining:
Caffeine, which is in so many delicious products, actually help relieve symptoms and boost the effectiveness of medications.
Sounds too good to be true? Not really!
It's all backed by science.
Feeling down? Going through mood swings? Having one of those days?
What if I told you that you can turn your day around as easy as getting a caffeine fix?
I'm not pulling this out of a hat. Science suggests that caffeine is not just a stimulant that keeps you alert, it can also improve your mood and help you become a walking ball of sunshine. This may seem like a tall order for caffeine but wait ‘til you order a tall cup of coffee and experience it yourself!
Based on a review conducted by A. Nehlig, having 75mg of caffeine (a cup of coffee) every 4 hours can lead to a “pattern of sustained improvement of mood over the day.” It can increase alertness and well-being, help concentration, improve mood and limit depression.

Want to hear something shocking?
Having your caffeine fix first thing in the morning will NOT perk you up.
But the good news is, you no longer need to make that sluggish early morning trip to the coffee-maker daily, nor join that long rush hour queue in your go-to café.
If you’re wondering whether we’re pulling some sick April Fool’s joke in the middle of August, there’s actually scientific evidence to all of this.
Caffeine has been known for its several benefits – from something so simple as helping you get over that afternoon slump, to lowered risk of Type 2 diabetes, Alzheimer’s and heart disease.
And for those wanting to lose weight, listen up!
Caffeine can also INCREASE METABOLISM.
Yes, you read that right. In fact, increased metabolism is observed for up to three hours after consuming 8 mg/kg of coffee (1).
So how exactly does the magic happen?
The effects of caffeine on one's mental state are an important area for scientists to explore because about 90 percent of the world's adults take the stimulating substance. Some prefer coffee, some tea, some soda pop and others take it in energy drinks. Caffeine is also in chocolate, some over-the-counter pain relievers and other products, including Viter Energy Mints.
As to depression and caffeine, some scientists say it helps alleviate symptoms, and some say it causes depression to worsen. Some claim caffeine's positive effects are so great that it can help prevent suicide.
Scientists have been studying whether eight 8-ounce glasses are necessary, and whether moderate amounts of caffeine make you dehydrated. The answers: no and no.
It was claimed caffeine makes you urinate so much you become dehydrated. In fact, taken in moderate amounts, caffeinated beverages can contribute to your overall daily water needs. Drink up, but beware you might have to go to the bathroom a lot.
Does caffeine stunt growth? A lot of people may say that, but the science doesn't support the contention. It's an urban legend now. About 90 percent of Americans consume caffeine in one product or another.
Caffeine is the world's most popular stimulant. It and coffee are legal, and in moderate doses do no harm but actually may help people by decreasing the risk of several conditions.
