For those who need to stay awake or get an instant energy boost, caffeine has been the go-to stimulant.
Found in various sources like coffee, cocoa beans, tea plant, nectar and even in totally unexpected foods like ice cream and yogurt, caffeine is a natural substance that’s considered a “moderately effective alerting agent.” 
This means that caffeine promotes alertness and keeps you awake.
But it also does so much more than that!
Aside from helping you wake up and get out of sluggish zone, here are 7 ways caffeine affects your health and body:
First things first. To understand how caffeine helps you get out of bed, you need to know what adenosine is.
As the body metabolizes ATP, a high-energy molecule used for a constant supply of energy, it liberates adenosine, which is the reason for why you feel sleepy. As the sleep-inducing molecule in the body, adenosine binds to receptors in the brain, leading to a slowdown in nerve cell activity and drowsiness.
Caffeine enters the picture when it binds into adenosine receptors. Because it looks like adenosine, caffeine gets mistaken as such and binds into the receptors. It then blocks and prevents actual adenosine from linking to receptors.
Voila – instead of slowing down nerve cell activities, caffeine does the complete opposite and stimulates you!

Athletes also enjoy the benefits of caffeine. In fact, 75% of the world’s elite athletes take advantage of caffeine’s performance-enhancing properties.
Caffeine helps athletes achieve optimal sports performance by delaying feelings of fatigue and preventing sleep.  This is especially helpful for those who need to cope with a different time zone and battle jetlag before gun start!
Also, a Men’s Health article reports that caffeine enhances “short-term, intense activities and improves endurance athletes’ times by up to 3 percent—a margin that could certainly matter in Olympic-caliber competition.”

Caffeine can turn you into a walking ball of sunshine. It improves your mood and eases the risk of depression.
According to a study, a tall cup of coffee containing 75 mg of caffeine can result in a “pattern of sustained improvement of mood over the day.” It can increase alertness and well-being, help concentration, improve mood and limit depression. 
Also, a report by the Harvard School of Public Health says that caffeine can make you a generally positive person. This is because of the substances that activate the reward systems of the brain, thus mimicking the effects of a mild antidepressant.

Dehydration happens when there’s not enough fluid in your body.
With dehydration comes electrolyte imbalance.
This makes it a little tougher to perform physical activity, more so an intense one like a workout.
If you suspect dehydration, you should put off exercise until you’re fully hydrated.
If you start noticing unusually more hair falling out – alarmingly more than usual – then ask yourself:
have you been stressed lately?
The link may not be that obvious, but it’s been established that stress causes hair loss.
So you’ve embarked on a mission called the ketogenic diet.
In the early days, your body may be going through a few changes, like a drop in insulin levels and a reduction in glycogen stores.
As a result, you may be experiencing weight loss and less of that bloated feeling… which could most likely be your primary goal for the diet, right?
But because the ratio of glycogen (stored carbs) to water is 1:3 grams, fewer glycogen stores can also mean less water in your body. And out goes your electrolytes too.
If this is a cause of worry for you, fret not! You can still keep a healthy level of electrolytes even under a low-carb diet. The key is to know what the rich sources of electrolytes are.
