Warm milk has long been touted as a drink that helps you sleep. Thats mostly due to comfort and ritual, but theres a small chance it could be traced to milks tryptophan content. Thats the amino acid that gives turkey its reputation for inducing sleep.

Tryptophan known to contribute to drowsiness and subsequent sleepiness, Dr. Greene says. Still, he cautions against blaming your fatigue on the cream in your coffee.

Lethargy, blood sugar and dehydration explain in part the paradoxical effects of coffee on our energy levels.

Caffeine, the main active ingredient in coffee, has a well-justified reputation for being an energy booster. But caffeine is also a drug, which means that it can affect each of us differently, depending on our consumption habits and our genes.

The paradox of caffeine is that in the short term, it helps with attention and alertness. It helps with some cognitive tasks, and it helps with energy levels, said , a professor in the Department of Psychiatry and Behavioral Sciences at the University of Washington, who has studied the impact of caffeine on people with A.D.H.D. But the cumulative effect or the long-term impact has the opposite effect.

Part of the paradoxical effects of caffeine results from its effects on what researchers refer to as sleep pressure, which fuels how sleepy we become as the day wears on. From the moment we wake up, our bodies have a biological clock that drives us to go back to sleep later in the day.

Chemically, caffeine looks similar enough to adenosine on the molecular level that it occupies those binding sites, preventing adenosine from binding to those brain receptors. As a result, caffeine works to temporarily suppress sleep pressure, making us feel more awake. Meanwhile, adenosine continues to build up in the body.

Caffeine May Interfere With Your Sleep

Why Does Caffeine Make Me Tired? Experts Explain

The caffeine in your coffee is a natural stimulant. It works by interfering with adenosine, a naturally occurring chemical that builds up through the day until it triggers sleepiness at night. As you sleep, levels drop again, only to start the cycle all over the next day.

Caffeine molecules block receptor sites, providing the temporary perception we are not as tired or sleep-deprived as we may be, says Dr. Greene. At a certain point, the adenosine volume will supersede caffeines effects, and we will most certainly have to sleep.

In other words, drinking too much caffeine could simply mean youll crash harder later.

This can lead to a vicious coffee cycle, in which you guzzle coffee to stay awake, stay up later thanks to the caffeine, and wake exhausted when your alarm goes off bright and early the next morning. And repeat.

In a 2018 study published in Risk Management and Healthcare Policy, the researchers discuss this cycle, stating, Researchers have commonly found that feeling tired in the morning leads to high caffeine use, which in turn is associated with impaired subsequent sleep patterns.

Caffeine Increases Blood Sugar Levels

Why Does Coffee Make Me Sleepy Instead of Giving Me Energy?

Coffees effects on blood sugar levels remains a point of controversy for researchers.

Many suggest that compounds inside coffee may improve glucose metabolism and reduce the risk of type 2 diabetes. However, the adverse effects of caffeine may negate the beneficial effects of drinking coffee.

According to a 2016 meta-analysis , caffeine can increase blood sugar levels by temporarily reducing insulin sensitivity.

In a small study, researchers observed that consuming 100 mg of caffeine adversely affected glucose metabolism in 10 healthy males with excess weight.

These findings suggest that caffeine, not coffee itself, can impact glucose metabolism, which can raise blood sugar levels.

People with high blood sugar may experience headaches, fatigue, trouble concentrating, increased thirst, or frequent urination until their blood sugar levels return to normal.

Coffee can affect more than a persons energy levels. The sections below discuss a few possible effects of drinking coffee.

Caffeine is also a vasoconstrictor. That means it makes blood vessels smaller and reduces blood flow. This reduced blood flow is why caffeine helps headaches. Amphetamine medications used to treat ADHD also make blood vessels smaller. Caffeine may have some effects similar to those of common ADHD medications.

Although the exact reason is unknown, reduced blood flow may help treat ADHD by reducing the activity of brain regions that are overactive, allowing them to better function and cooperate with the rest of the brain.

Caffeine Blocks Adenosine Receptors In The Brain

Adenosine is a brain chemical that affects the sleep-wake cycle . Adenosine levels increase during waking hours and decrease during sleep.

Normally, adenosine molecules bind to special receptors in the brain, which slows down brain activity in preparation for sleep. However, caffeine prevents this from happening by binding to adenosine receptors.

The body rapidly absorbs caffeine, so people may feel its effects within minutes. In fact, the body absorbs 99% of caffeine within 45 minutes of consuming it. Once the body fully metabolizes the caffeine, its effects will wear off.

The length of time caffeine stays in the body varies from person to person. Although it blocks adenosine receptors, it does not affect the production of new adenosine molecules.

When caffeine wears off, adenosine molecules can bind to their receptors, which can cause sleepiness.
