6 Ways Coffee Makes You Tired

Coffee is widely consumed in the United States, with approximately 75% of American adults enjoying it, and nearly half doing so daily. Rich in caffeine and mood-enhancing compounds, coffee is a popular choice to boost alertness and mood. Coffee is often incorporated into morning routines for a wakeful start to the day.

Despite its stimulant properties, some may feel that coffee makes them feel sleepy rather than alert. 

We’ll explore potential reasons for this and offer strategies to prevent caffeine from making you tired. 

6 Reasons Why Coffee Makes You Tired

Sleep Deprivation

Sleep deprivation is prevalent, with over one-third of Americans falling short of the recommended seven hours of sleep per night. Despite coffee providing a quick energy boost, it’s not a substitute for adequate sleep. Sleep deprivation can reduce alertness, slow response times, and impair cognitive function. 

Relying on coffee to combat tiredness can backfire, as excessive caffeine intake adversely affects sleep, creating a counterproductive loop. Increased coffee consumption disrupts sleep, leading to prolonged tiredness—a cycle where fatigue prompts more coffee consumption, exacerbating the problem.

Caffeine Tolerance

Caffeine tolerance may explain why coffee loses its effects over time. Initial caffeine intake enhances mood, reaction times, and physical performance. Similar to alcohol tolerance, regular consumption diminishes responsiveness. 

Increasing coffee intake to reclaim positive effects can disrupt sleep without reinstating the initial benefits. Additionally, three days of consistent caffeine use can induce withdrawal symptoms upon cessation. 

Effectively understanding and managing caffeine tolerance is vital for preserving coffee’s desired impact on alertness.

Dehydration

Coffee, being a diuretic, can increase the need to urinate, leading to fluid loss and potential dehydration. Frequent bathroom trips during the night can disrupt sleep, contributing to fatigue the next day. 

Mild dehydration itself can induce tiredness, diminish cognitive performance, impair memory, and elevate anxiety and tension.

It’s worth noting that the impact on hydration may vary, with non-regular coffee drinkers being more susceptible. The effect may not be noticeable until a certain level of caffeine is reached. 

Being mindful of hydration is essential, as it plays a role in both the short-term and long-term effects of coffee on alertness and well-being.

Altering Blood Sugar 

Morning coffee consumption may contribute to insulin resistance, affecting the body’s glucose tolerance. This can make you more susceptible to sugar or carbohydrate sensitivity. It can lead to a temporary spike in blood sugar levels.

Even if blood sugar levels don’t clinically peak, a subsequent drop after the initial surge can result in heightened tiredness. 

Adenosine Levels

Adenosine, a sleep-promoting chemical released in larger quantities when sleep-deprived, induces feelings of sleepiness. Coffee combats this by blocking adenosine receptors, reducing tiredness. 

However, the body may compensate by increasing sensitivity to adenosine, leading to a surge in sleepiness and muscle fatigue once the coffee’s effects wear off. Understanding this interplay is crucial for managing the balance between coffee-induced alertness and potential post-caffeine fatigue.

Caffeine Metabolism

Individuals metabolize caffeine differently, leading to variations in its effects. Some, known as slow metabolizers, may experience a delayed alertness effect, while fast metabolizers may feel a quicker decline, leading to early sleepiness. 

Factors such as smoking accelerate caffeine metabolism, while conditions like pregnancy or liver disease can slow it down. Recognizing these factors is crucial, helping individuals tailor their caffeine intake to match their unique metabolism for optimal alertness management.

How To Have Coffee The Right Way

Here’s how you can maximize the benefits of coffee:

  • Prioritize Adequate Sleep: Ensure you get enough sleep, as coffee’s alertness boost has limits for higher cognitive processes. Persistent tiredness may indicate sleep deprivation, prompting a need for longer and potentially higher-quality sleep. For adequate sleep, make sure you cut off the screen time. You can use the Ocushield Anti Blue Light Tempered Glass Screen Protector for iPhones.
  • Time Your Coffee Consumption: Drink coffee strategically, preferably in the morning. Studies suggest that consuming coffee within six hours of bedtime can disrupt sleep. Follow the U.S. FDA recommendation of no more than 400mg of caffeine per day, adjusting based on individual sensitivity.
  • Be Mindful of Added Sugar: Watch what you consume with your coffee, including added sugar. In many places, coffee drinks contribute hidden sugars to diets. For individuals with diabetes, sugar intake can lead to fatigue. Additionally, caffeine might affect the body’s sugar management, potentially exacerbating fatigue. If you are into drinking, you can consider the sugar-free natural wines from Dry Farm Wines
  • Hydrate Effectively: Counteract potential dehydration from higher caffeine doses by drinking plenty of water. This is especially crucial for non-regular coffee drinkers, who may be more sensitive to its diuretic effects.
