If these questions are burning a hole in your brain, you’re right where you need to be. Keep reading to find out everything you need to know about coffee and its effects.

Why Does Coffee Make You Energetic?

Coffee contains an ingredient called caffeine. Caffeine, a stimulant, works by making the communication between your brain and body faster. Coffee also blocks adenosine, a neurotransmitter associated with tiredness. At the same time, it enhances adrenaline production. 

This is why drinking a cup of coffee can make you feel energetic. But how much time does it take to do so? Find your answer below!


How Much Time Does it Take for Coffee to Kick In?

A diluted cup of coffee is quickly absorbed by the body, so you start feeling its effects in seconds. In fact, caffeine is metabolized at a rate of 99 percent 45 minutes after consumption. 

Caffeine’s effects might be evident as quickly as five to ten minutes following its consumption. So if you drink a cup of coffee, you will start experiencing that boost of energy in just 10 minutes. 

The typical effects of a coffee kick in most intensely about 30-60 minutes after drinking it. 

How Long Does Caffeine Stay in Your System?

Coffee’s caffeine might take up to 10 hours to fully exit your bloodstream. But after about 5 hours, half of the caffeine leaves your system. 

To understand this better, imagine you had a cup of coffee with 20 mg of caffeine in it. After 5 hours, 10 mg would have left your body through urine. 

How Long Does It Take for Black Coffee to Kick In?

Black coffee is simply coffee without milk or any creamer. And since there is no caffeine in the milk itself, the amount of caffeine in Black coffee is the same as a milky cup of coffee. 

Therefore, black coffee also takes about 10 minutes to start showing its effects and about 30-60 minutes to reach peak effects. 

How Long Does It Take for Espresso to Kick In?

Again, since adding anything non-caffeinated to espresso/black coffee does not affect its caffeine content, espresso also acts similarly to regular coffee. 

You will start noticing the effects after 10 minutes, and it will kick in at a peak after about 30-60 minutes of consumption.

How Long Does Coffee Keep You Awake?

Half of the caffeine you take is metabolized by your body about 6 hours after you consume it. So if you take a freshly brewed cup in the morning, it should keep you energetic and awake for your working hours. 

If you’re looking to pull an all-nighter, taking coffee at dinner time may be a great option. This way, you may be able to stay awake throughout the night. And if you feel drowsy at any point, you can simply drink another cup. 

How Long Does Caffeine Affect Blood Pressure?

While coffee gives you an instant dose of energy, it has two other effects. One of the most prominent of them is the rise in blood pressure one experiences due to coffee’s caffeine content. 

About 1.5-2 cups of coffee can raise your systolic blood pressure by 8 mm Hg and your diastolic pressure by 6 mm Hg

This increased pressure may persist for up to 3 hours post-consumption. However, this timing varies greatly depending on how regular a coffee drinker you are. If you’re accustomed to it, this effect might be far milder.

How Much Coffee Can I Safely Drink?

If you’re a big fan of a steaming hot cup of coffee, it must be hard to resist the urge to have it multiple times a day. But you have to be careful! 

According to the FDA, 4-5 cups of coffee (400 mg/day) are safe. But for people more sensitive to caffeine or pregnant or breastfeeding, this amount may not be safe. So if you have conditions that make you less resistant to caffeine, consult your physician.
