How Drinking Coffee First Thing After Night Of Poor Sleep Impacts Blood Sugar
Physiologists at Bath examined 29 men and women after each of them experienced three distinctly different nights of sleep. In one experiment, the participants enjoyed a normal night of rest. This was followed by a sugary drink which roughly equals the calories eaten during breakfast.
During the next two experiments, each volunteer was woken up every hour throughout the night to create a disrupted sleep. In one instance, the participants were given the same sugary drink after waking up. After the other bad sleep, researchers gave the group a strong black coffee 30 minutes before having their sugar. A blood test was then taken following each night of sleep and the drinks each person consumed.
The results show that one good or bad night of sleep makes little difference in a persons blood sugar/insulin responses. Researchers note that previous studies link several nights of insomnia to metabolic issues, but add a single incident where you cant fall asleep doesnt carry the same weight.
When coffee enters the picture, thats when the body sees a drastic change. Study authors report participants drinking coffee right after a bad night of sleep increased the blood glucose response to breakfast by around 50 percent.
We know that nearly half of us will wake in the morning and, before doing anything else, drink coffee intuitively the more tired we feel, the stronger the coffee, Prof. Betts explains.

Does The Amount Of Caffeine Matter
Donât start loading up on coffee to lower your blood glucose levels. Your response to caffeine will also depend on your baseline blood glucose level, how much caffeine you consume, genetics, and how your body handles caffeine. Most healthy people can safely consume up to 400 mg of caffeine per day without adverse side effects.
One thing to consider is that your response may depend on more than just CGAs. Recent studies suggest the difference in your glucose response may stem from your genetic makeup, with specific genes linked to your rate of caffeine metabolism. For some, this could mean they metabolize coffee quicker, resulting in more dramatic glycemic responses from the same amount of caffeine.
Before you decide what a healthy level looks like for you, the best thing to do is to experiment and pay attention to your threshold to figure out how much caffeine is appropriate for your daily limit. Even if youâre healthy, itâs a good idea to consume caffeine in moderation and find what amount is right for you. Remember that, like everything else, caffeine has its side effects and risks. It can lead to headaches, restlessness, and anxiety. Certain types of coffee, like unfiltered coffee, can lead to an increase in cholesterol, and there may also be an increase in your risk of things like heartburn. And, of course, if youâre loading up on the cream, milk, and sweetener, too, you may be putting yourself at risk of diabetes.
How Does Coffee Affect Your Blood Sugar
Studies show that even though coffee can temporarily increase blood sugar, long-term it’s protective against type 2 diabetes for otherwise healthy people.
While it isn’t clear exactly why this is the case, one reason it supports healthy blood sugar may be related to the many antioxidant compounds found in coffee that lower inflammation. Daily coffee consumption is linked to reduced markers for inflammation in the body. The compounds in coffee could also improve glucose uptake into your muscle cells.
A large meta-analysis found that drinking more coffee was associated with a significantly decreased risk of developing type 2 diabetes for both caffeinated and decaffeinated coffee, so the protective compounds in coffee are likely independent from caffeine. But coffee could be problematic for people with type 2 diabetes because of caffeine.

How Does Caffeine Affect Your Blood Sugar
A growing body of research suggests people with type 2 diabetes react to caffeine differently. It can raise blood sugar and insulin levels for those with the disease.
One study looked at people with type 2 diabetes who took a 250-milligram caffeine pill at breakfast and another at lunchtime. Thatâs about the same amount as drinking two cups of coffee with each meal. The result: Their blood sugar was 8% higher than on days when they didnât have caffeine. Their reading also jumped by more after each meal.
Thatâs because caffeine can affect how your body responds to insulin, the hormone that allows sugar to enter your cells and get changed into energy.
Caffeine may lower your insulin sensitivity. That means your cells donât react to the hormone by as much as they once did. They donât absorb as much sugar from your blood after you eat or drink. This causes your body to make more insulin, so you have higher levels after meals.
If you have type 2 diabetes, your body already doesnât use insulin well. After meals, your blood sugar rises higher than normal. Caffeine may make it tougher to bring it down to a healthy point. This may lead to too-high blood sugar levels. Over time, this may raise your chance of diabetes complications, like nerve damage or heart disease.
Coffee Does Not Seem To Raise My Blood
The graphs below show my blood-glucose levels over a 4-hour period for three separate experiments. The blue line is the blood glucose on a morning I drank coffee. The red line is on a morning without coffee.
Experiment one
The first experiment indicated that coffee may raise my blood sugar. But only slightly:
The graph above could suggest that drinking coffee prevents my blood-sugar levels from dropping to the same levels as the morning when I didnt drink coffee.
Experiment two
The second experiment indicates that coffee does NOT noticeably raise my blood sugar. Theres a lot of variety in my blood-glucose levels on these two days, but to us it seems that coffee does not raise my blood sugar relative to not drinking coffee .
Experiment three
The third experiment also suggests that coffee does not raise my blood sugar much. My blood-sugar levels are quite flat, both on the morning when I drank coffee and the morning I didnt, indicating that the coffee didnt impact my blood-sugar levels much.

How To Make Black Coffee
While there is no one correct way of making black coffee and different people make their black coffee in their own ways, there are steps you can take to ensure that your beverage tastes amazing every time.
There are two ways you can make black coffee by grinding it on your own, or by using a machine.
If you want a clear black coffee with a truly delicate taste, then grinding it on your own is the best option. Take about three tablespoons of coffee and grind them till they are as fine as sea salt. Boil about 600 grams of water. Add a filter to your dripper, filling it with the ground coffee. Gently tap the surface and pour it over in a cup. Your black coffee will be ready in no time.
Another option is to simply use a coffee machine, which most people do because of how convenient it is.
Using The Spike From Coffee To Prevent Lows
If you tend to go low during or after exercising, you can use coffee as a way to limit that risk
Drink a cup of coffee about an hour before an intense cardio workout, for example, could prevent low blood sugars without requiring you to eat food, calories, carbs, etc. But remember not all types of exercise drives blood sugar down so you want to combine the coffee with the right type of exercise.

Even though those flavored creamers are a mere tablespoon of liquid, they are very high in sugar. Enough sugar to definitely cause an even larger spike in your blood sugar.
One of the most useful things you could do for yourself as a coffee drinker with diabetes is to gradually adjust your tastebuds to appreciate the taste of black coffee.
Try removing the sweetener and milk from your coffee for two weeks. Just two weeks! And see how you start to like the taste of black coffee! You might be surprised to find that you eventually find sweetened coffee to taste overwhelmingly sweet.
Watch Out For The Infamous Dawn Phenomenon
It’s not uncommon to wake up to a high blood sugar reading, even if your number was in the green zone when you went to bed. You may be experiencing the “dawn phenomenon,” which occurs when the body preps for waking up by releasing cortisol and other hormones, between 2 and 8 a.m., according to the Mayo Clinic.
These hormones make the body less sensitive to insulin, and in people with diabetes, can contribute to a morning blood sugar spike. Alternatively, you may start the day with a low glucose level if, for example, you’re taking too much insulin or medication at night or not eating enough in the evening, McDermott says. She notes that eating a small, protein-rich, low-carb snack at bedtime can sometime help by shortening the fast .
If you see a trend in your morning readings or they’re highly erratic from day to day you’ll want to work with your doctor or diabetes educator to identify the problem so you can take steps to correct it, says Bonsignore.

How Does Coffee Raise Blood Sugar If You Have Diabetes
As we know caffeine is the main ingredient of coffee. It increases the levels of epinephrine, cortisol and reduces insulin sensitivity. Insulin hormone is responsible for the conversion of blood glucose into energy. Lower insulin sensitivity causes blood sugar accumulation which further increases the risk of liver problems, nerve damage, and heart attack.
Why Caffeine Can Spike Your Blood Sugar
We often think that its the caffeine itself that gives us energy when we drink a cup of coffee, tea, or soda, but its actually related to what the caffeine triggers hormonally in our body.
Caffeine is a stimulant that tells gives you energy through a variety of ways, explains Science Direct:
We also tend to think of adrenaline as something that simply gives us energy, but like caffeine, its more complicated than that! Instead, adrenaline actually triggers your liver to release stored glucose, giving you the fuel you need to endure a soccer game, a rollercoaster ride, or your usual Monday morning.

Drinking Caffeine At Different Times Of Day
Its also important to notice whether the time of day you drink caffeine or coffee changes the impact, too.
Most people experience some level of insulin resistance in the morning which wears off throughout the day. Adding coffee to an already insulin resistant situation can be the recipe for very high morning blood sugar. If you also have dawn phenomenon , it might be an idea to convert your morning coffee into you afternoon pick-me-up
Traveling Can Disrupt Routines And Thus Sugars
Skipping a few time zones during a long flight throws almost everyone off, but it’s an even bigger concern for people with diabetes. The time change can disrupt your medication schedule and cause unusual eating and sleeping habits, which interfere with blood sugar control, McDermott says.
Plus, when youre on vacation or traveling, you may eat more, drink more alcohol, or be more active all of which can cause blood sugar swings. She advises checking your blood sugar more frequently while traveling to catch any concerning trends before they become serious problems.
McDermott also recommends packing healthy carb-balanced snacks as well as a refillable water bottle to help you stay hydrated. Try to eat something every four hours throughout the day, even if it cant be at the exact same times you usually eat. If you take insulin and you’re shifting time zones, be sure to work out a medication schedule with your diabetes care team before your trip so you don’t mistime any doses, she says.

How Caffeine Impacts Your Blood Sugars
While coffee and caffeine have been shown to possibly prevent the condition in people who dont already have it, that morning cup of Joe could have some serious effects on your diabetes.
The Science
According to WebMD, caffeine can impair insulin reaction. This means it may take more time for your dose of insulin to fully kick in. Caffeine can also increase your bodys resistance to insulin. This can ultimately lead to high blood sugar levels and to further diabetes complications.
In addition, a 2008 Duke University study showed that caffeine may have an impact on your blood glucose levels. The study examined people with type 2 diabetes. One group of participants took 500 mg caffeineabout the equivalent of about two cups of coffeeevery day for a week, while the second group abstained from caffeine. Each persons blood glucose levels were tested multiple times throughout the week, and it was found that those who drank caffeine had blood sugars around 8 percent higher than those who didnt take caffeine.
