Did you know timing when you drink coffee intake may improve your life? In the morning when the alarm goes off, the first thing many people think of is getting a coffee fix.
Coffee and tea don’t just taste good, the ritual is not just comforting, you actually need the caffeine to feel alert, normal and ready to face the day.
And if you’ve developed a dependence on caffeine, you might even get a headache, be crabby and out of sorts or be too sleepy to perform well if you don't get your fix.
But what if we told you this is all wrong? That it’s better to wait until mid-morning to drink your coffee, tea or energy drink, or you could risk fatigue or even poor quality of life?
It has to do with body chemistry and the circadian rhythm or the body’s internal clock, which regulates when you feel awake or sleepy.
When you first get up, your body produces the stimulating “stress hormone” cortisol, which helps you wake up and be alert after a night’s sleep. But if you take caffeine first thing, your body may produce less cortisol, which could make you tired and dependent on caffeine.
A study  published in The Journal of Clinical Endocrinology and Metabolism says there are three times during the day when the body’s cortisol levels are at their highest: between 6 and 10 a.m., from noon to 1 p.m., and from 5:30 to 6:30 p.m. The very highest levels of cortisol peak between 8 and 9 a.m.
So take your caffeine around 9:30 to 11:30 a.m. and again between 1:30 and 5 p.m. If you have to get up early and go to bed early, you might drink your coffee or have your Viter Energy Mints  earlier in the afternoon.
The peak cortisol time frame varies some from person to person depending on when they wake up. A person’s weight and gender do not seem to make the peak times vary, the study said.
The scientific study states: “Cortisol has a distinct circadian rhythm regulated by the brain’s central pacemaker. Loss of this rhythm is associated with metabolic abnormalities, fatigue, and poor quality of life.”
A short video from the popular science YouTube channel AsapSCIENCE explains the phenomenon of cortisol, caffeine and the morning routine:
The narrator of the video asks:
What if I told you you’ve been drinking your coffee incorrectly this entire time Scientists have actually found that consuming coffee or energy drinks during peak cortisol production greatly diminishes the caffeine’s effect and builds up a greater tolerance to the drug in the long run.
Overall that means you get less of a buzz and need even more to stay awake in the future. Science says wait at least an hour to take your cup of joe, and your body will be optimally ready to go.
The video says the best time to drink coffee is during non-peak times. This is when your body needs the boost, and also it is less likely that the caffeine will interfere with your body chemistry and circadian rhythms if you take it then.
Of course, many people have trouble getting to sleep if they take caffeine later in the day, so you might want to avoid a cup of java or tea in the 5:30 to 6:30 p.m. peak cortisol time frame.
The stimulating effects of caffeine from coffee last 3–5 hours, and depending on individual differences, about half of the total caffeine you consume remains in your body after 5 hours.
Consuming coffee too close to bedtime, such as with dinner, can cause sleeping problems.
Also, NPR reports  on a study that gave participants a double shot of espresso three hours before bedtime.
That study showed the dose of caffeine slowed the release of another body chemical, melatonin, by about 40 minutes. Melatonin is a human hormone that helps people get to and stay asleep.
Circadian physiologist Kenneth Wright, one of the study's lead researchers, told NPR:
We found that caffeine did indeed, in the evening, shift your clock later. It was about half the effect the scientists noticed when they instead exposed the volunteers to bright light. What we’re seeing here now is another way that caffeine impacts our physiology that we didn’t know about before in humans.
The Washington Post reports  that when people talk about developing tolerance for caffeine, they are unknowingly referring to inhibition of cortisol production.
“Coffee drinkers who are exhausted in the morning without their coffee have likely altered their circadian rhythm in such a way that they need the caffeine boost in order to reach the level of wakefulness they used to achieve without it,” the article states.
Caffeine taken habitually seems to replace cortisol. But you can have your coffee and drink it too by timing your caffeine intake during troughs in cortisol production.
Timing the intake of caffeine for athletes can be important. Healthline.com has a recommendation  on timing your caffeine:
If you’re looking to optimize coffee’s beneficial effects on exercise performance, it’s best to consume the beverage 30–60 minutes before a workout or sporting event.
This is the time it takes caffeine levels to peak in your body.
The effective dose of caffeine for improving exercise performance is 1.4–2.7 mg per pound (3–6 mg per kg) of body weight.
For a 150-pound (68-kg) person, this equates to about 200–400 mg of caffeine, or 2–4 cups (475–950 mL) of coffee.
In addition to getting your caffeine, the mints will freshen your breath, which can be a convenience if you are in a place where you can't brush your teeth.

How bad is caffeine withdrawal? People who have a caffeine habit may empathize with a scene of the 1931 production of Frankenstein, in which the mad scientist exults over the animation of his monster, exclaiming “It’s alive! It’s a alive, it’s alive!” I know I get animated in the morning after drinking my first cup of the ichor we call coffee.
Caffeinated products are wildly popular worldwide, used by as much as 90 percent of the adult population. An estimated 80 percent of American adults take caffeine in one product or another, and it’s estimated half of those people are prone to headaches for one reason or another. If you are among the caffeine users who get caffeine withdrawal headaches from coffee, tea or energy drinks, there are a few things you can do to minimize the pain.

Studies of caffeine show that it does not increase the risk of death, but it causes a habit or possibly a dependence that the American Psychiatric Association now lists in its diagnosis manual as a disorder that warrants more study.
Scientists study caffeine and its use by humans a lot, some say more than any other psychoactive substance in the world. Caffeine is the most widely used drug, and more scientists are saying now there should be yet more studies into dependence and other aspects of caffeine consumption.

What is the chemistry of coffee? Caffeine is the most famous chemical compound in coffee, but roasted coffee beans contain more than 1,000 other compounds. Some of these chemicals are noxious but still are not unhealthy because they are present in such low amounts.
You never hear anybody wake up and say, “I need a big dose of putrescine and dimethyl disulfide in my morning cup.”
