Many people enjoy starting their day with an espresso beverage. Espresso is made by brewing finely ground espresso beans rapidly with hot water in order to produce a rich, highly concentrated shot of espresso. Espresso is known for being stronger and arguably better tasting than a traditional coffee beverage. You may wonder, how long does espresso last in your system?

Espresso contains more caffeine than a traditional coffee beverage due to how concentrated it is. The effects of caffeine typically last an average of 5 hours, although this can vary somewhat from person to person. Some people assume that because espresso is stronger than some coffee beverages, the effects of the caffeine will last longer. However, this is not the case.

No matter how much caffeine is consumed, its effects will not necessarily last longer. Rather, they will be stronger. If you consume a higher amount of caffeine such as espresso, you may notice that the effects of caffeine are stronger but still only last the normal amount of time.

Many people have debated the benefits of caffeine and whether or not it is healthy to consume on a regular basis. On its own, caffeine offers no nutritional value and is simply a stimulant. Caffeine may be beneficial in reasonable doses to some people, but it can be harmful to others. You should consider your own personal caffeine intake and health to determine whether or not caffeine is beneficial for your consumption. 

How long does espresso last? In this article, we will delve into why caffeine lasts as long as it does and how this may vary from person to person, the effects you feel after consuming caffeine, and the risks and benefits.

How Much Caffeine Is in Espresso?

A shot of espresso is often used in coffee beverages such as an americano or cappuccino. A latte is made with syrup, milk, and one or two shots (or more) of espresso, depending on what size coffee you typically order. A shot can also be consumed by itself, and some enjoy its rich, dark flavor.

A single shot of espresso typically contains roughly 60mg of caffeine. Thus, most drinks made with espresso contain 60-120mg of caffeine. 

Most people will feel the effects of caffeine after consuming 100-200mg of caffeine. Some people may have higher tolerances to caffeine, but it is not recommended to consume more than 400mg of caffeine each day. So, how long does espresso last? No matter how much you consume, the peak of the effects will last around 5–6 hours. 

What Is the Half-life of Caffeine?

Half-life is the amount of time it takes for your body to break down half of a substance after consuming it. Effects of caffeine are measured through the half-life because it is difficult and nearly impossible to track the amount of time it takes for the remaining half of the caffeine to break down.

The half-life of caffeine is between three to five hours depending on the individual person’s metabolism and tolerance to caffeine. 

If you consume one shot of espresso, you will feel the effects of caffeine in as early as 15 minutes, but it can take up to 60 minutes depending on the speed of your metabolism and tolerance to caffeine. 

Even if you consume a high dose of caffeine, the amount of time it takes for you to feel the effects will still fall within this window. It is possible to develop a high tolerance to caffeine, but even if the effects do not feel noticeable, it is not recommended to consume more than 400mg of caffeine in a day. 

The peak effects of caffeine can last for up to 6 hours for an average person, so it is not recommended to consume caffeine within 6 hours of when you plan to sleep. For example, if you plan to fall asleep at 10 pm, you should not consume caffeine after 4 pm. 

What Are the Effects of an Espresso Shot?

While espresso is more concentrated and contains a higher amount of caffeine per ounce compared to a cup of coffee, a full cup of coffee will typically contain more caffeine than a single shot of espresso. Thus, if you frequently consume a standard cup of coffee, a single espresso shot may not feel very strong to you. 

For this reason, many people who seek out the stronger caffeine effects of espresso will opt for a double shot instead of a single shot. A double shot has more caffeine than a standard cup of coffee without being a drastically higher dose of caffeine than what most people are accustomed to. 

Considering that 400mg is the max recommended dose of caffeine you should consume in a day, it’s possible to consume 6 shots of espresso daily. However, the effects of 6 shots of espresso will feel quite strong if you don’t already tend to consume high amounts of caffeine.

For most people, 2-3 shots of espresso is more than enough to feel wide awake. If you’re wondering how long espresso lasts, it is important to note that consuming more shots will not increase the longevity of the caffeine effects.  

How Does Caffeine Impact Adenosine?

Caffeine blocks adenosine, which is a receptor that regulates the rhythm of the heart and helps us to fall asleep. When we are awake during the day, adenosine gradually increases until we feel tired enough to sleep. Adenosine also slightly suppresses the functions of immunity. 

“Feeling the effects of caffeine” simply means that caffeine is successfully blocking your adenosine receptors.

Caffeine May Increase Your Heart Rate

Many people report feeling jittery or anxious after consuming high amounts of caffeine. This is because caffeine is blocking the adenosine receptors that regulate the rhythm of your heart, so caffeine can temporarily raise your blood pressure. 

Caffeine is not known to have long term effects on blood pressure, but if you have any problems with having low or high blood pressure or an irregular heartbeat, it is best to consult with a doctor before consuming caffeine. 

Caffeine May Increase Urination

Caffeine is a diuretic, so it can dehydrate you while also causing you to urinate more frequently. This is because caffeine increases blood flow to the kidneys. After consuming caffeine, it is important to drink enough water to rehydrate yourself. 

Mental Alertness May Increase

Most people consume caffeine to feel more awake and alert. The reason this occurs is because caffeine blocks the adenosine receptors that make you feel drowsy. 

Your Energy Consumption May Be Improved

Caffeine causes your body to use fat as the primary energy source instead of glucose. Fat is a more effective and sustainable energy source, so you may feel more energized after consuming caffeine. 

Caffeine can even lead to weight loss for this reason, but it is not recommended to use caffeine as a weight loss aid because large amounts of caffeine can be harmful. 

Caffeine May Boost Your Immunity

Due to the fact that adenosine lowers immunity, caffeine can raise your immunity by blocking the adenosine receptors. Moderate caffeine intake may help to reduce the risk of cancer and heal your gut. 

Your Aerobic Capacity May Improve

After consuming espresso, you may find that you can withstand physical activity with more energy than usual. This is because caffeine increases airflow to the lungs. However, it also  decreases blood flow to the lungs.

You might find that you can exercise with more energy, but this will be limited by a lowered stamina because of decreased blood flow to the lungs.

The Correlation Between Addiction and Caffeine 

Caffeine can become addictive to some extent, and some people who consume excessive amounts of caffeine may become addicted because they rely on its energizing effects to start their days with energy and mental clarity. 

After becoming addicted to caffeine, you may struggle to stop consuming caffeine without feeling effects such as:

  • Anxiety
  • Nausea
  • Drowsiness
  • Migraines

Due to the addictive nature of caffeine, it is best to monitor your caffeine intake and consume a reasonable amount of caffeine.  Try not to consume more than 400mg of caffeine in one day. There’s not much point in consuming more than that anyway because an excessive amount of caffeine will not make the effects of caffeine last any longer. 

Final Thoughts

So, how long does espresso last in your system? Espresso provides a safe and effective boost of energy for roughly 5 hours after consumption. The effects of espresso can last for a longer or shorter amount of time depending on your individual metabolism and tolerance to caffeine. 

Most people can safely consume 1-3 shots of espresso in order to feel the effects of caffeine and go about their day with an increased level of mental clarity and energy. As long as you monitor your caffeine intake and consume it responsibly, espresso can be an enjoyable and beneficial way to start your day.
