A group of researchers from the University of Nevada-Reno discovered that coffee grounds can be used as biodiesel, and quite possibly in the near future, your car fumes will smell like a cup of freshly brewed cappuccino. But that very first cup of coffee that fuels most of us in the morning may not be the best way to start your day. In fact, doctors believe the best time to enjoy your cup of java is mid- to late-morning, between 9:30 a.m. and 11:30 a.m.
We at Bright Side usually look forward to our first cup of coffee in the morning, but the effects it can have on your body when you drink it on an empty stomach can be a true wake-up call.
1. You may feel sleepier.
Coffee is a wake-up drink for many of us, but drinking it as soon as you roll out of bed may have the opposite effect. Caffeine doubles the levels of stress hormones and may lead to problems with sleep, which results in tiredness. If you start your day with a cup of cappuccino with sugar, you might feel sleepy again after a short period of time. This happens because our body produces insulin to offset the sugar, causing your blood glucose levels to drop, which results in a lack of energy and anxiety.
2. Your body may lose essential minerals more quickly.
Having your regular dose of coffee early in the morning can cause you to lose many essential vitamins and minerals. It can sabotage the absorption of iron, magnesium, and B vitamins which are vital to our nervous system. Too much caffeine can also leach calcium from your bones, making them weak and brittle.
3. It may upset your stomach.
While your beloved beverage will help you to wake up in the morning, it may also give you the urge to use the bathroom more often. In fact, some medical experts even recommend drinking coffee as a way to prepare for certain exams. Coffee activates our nervous system, which in turn affects the colon and may cause diarrhea. Many people also like adding milk or cream to their morning cup of java, and because most of us have difficulty digesting lactose, it may cause stomach discomfort as well.
4. It may lead to weight gain.
Although black coffee may help you burn fat, it can also upset your healthy sleep patterns. When you don’t get enough sleep, you tend to feel hungrier and have more cravings for sweet snacks. Many coffee beverages, like popular sweetened blends, are packed with sugar and calories and might cause you to gain extra pounds.
5. It can worsen anxiety.
When you wake up in the morning, your stress hormones levels are usually at their highest. Because caffeine is a stimulant, it gives your body a jittery effect and can even trigger anxiety attacks for some people.
6. It can dry out your skin.
Because coffee makes you use the restroom more often, it dehydrates your body. When you become dehydrated, it’s harder for toxins to exit the body through your skin. This, in turn, dries the skin out and makes it more vulnerable to various problems, like premature wrinkles.
7. It may raise your blood sugar level.
Your morning cup of coffee makes it harder for your cells to regulate blood sugar, which can lead to various diseases. High blood sugar, in turn, can lead to weight gain and even raise your risk of skin infections.
When do you usually drink your first cup of coffee? Have you noticed any of these side effects?

Can you solve this math puzzle
Have you ever come across a math problem that seems easy at first glance, only to realize that most people get it wrong? The equation 9 – 9 ÷ 9 + 9 – 9 ÷ 9 = ? is one such puzzle that confuses many. It looks simple, but if you’re not careful, you might end up with the wrong answer.
Are you ready to put your math skills to the test? Take a moment to solve it before reading ahead. Think you got it right? Let’s find out!
Why Do So Many People Get This Wrong?
At first glance, this equation appears straightforward. However, small details in mathematical rules trip people up. Here are some common mistakes that lead to the wrong answer:
- Ignoring the Order of Operations (PEMDAS/BODMAS) – Many people solve the problem from left to right without following the correct order of operations.
- Misplacing Parentheses (Even When They Aren’t Written) – Some assume parentheses where there are none, changing how they approach division and subtraction.
- Rushing Through the Calculation – The problem is designed to look easy, so people tend to solve it quickly and overlook critical steps.
So, what’s the correct approach? Let’s break it down step by step.
Step-by-Step Solution
To solve this equation correctly, we must follow the order of operations. The most commonly used rule is PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).

The given equation:
9 – 9 ÷ 9 + 9 – 9 ÷ 9
Step 1: Solve the Division First
According to PEMDAS, division comes before subtraction and addition. So, let’s divide first:
- 9÷9=19 ÷ 9 = 19÷9=1
- 9÷9=19 ÷ 9 = 19÷9=1
Now, substitute these values back into the equation:
9 – 1 + 9 – 1
Step 2: Perform Addition and Subtraction from Left to Right
Now, we calculate in order from left to right:
- 9 – 1 = 8
- 8 + 9 = 17
- 17 – 1 = 16
So, the correct answer is: 16
Common Incorrect Answers and Why They Happen
Many people arrive at incorrect answers because they don’t follow the correct order of operations. Here are some of the most common mistakes:
- Answer: 0 – This happens when someone groups all the numbers together without following PEMDAS, incorrectly simplifying the problem as:
9−9−9+9−9=09 – 9 – 9 + 9 – 9 = 09−9−9+9−9=0 - Answer: 1 – Some mistakenly subtract 9 from itself first before dividing, leading to:
(9−9)÷9+9−9÷9=1(9 – 9) ÷ 9 + 9 – 9 ÷ 9 = 1(9−9)÷9+9−9÷9=1
These errors reinforce the importance of following the correct mathematical rules step by step.
Why Understanding Order of Operations Matters
You might wonder—why does it even matter? Well, mathematics is built on logical rules, and following them correctly ensures we get consistent, accurate answers. The order of operations is used in everything from programming to engineering to everyday calculations.

Think about it this way: If a recipe tells you to bake a cake at 350°F for 30 minutes before adding frosting, you wouldn’t reverse the steps, right? Math works the same way—sequence matters!
