Hey there! I’m Craig, and today we’re diving into a big question: “Why do we get dark bags under our eyes when we’re tired?” Let’s explore this interesting topic together!
First, it’s important to know that dark circles and eye bags are not the same thing. Dark circles can appear under your eyes due to genetics and tiredness. Eye bags, on the other hand, are caused by a mix of different factors. Let’s find out more about each!
The skin under your eyes is super thin and covers muscles, fatty tissue, and blood vessels. The darkness you see can be affected by your skin color, how thick your skin is, and your genetics.
One idea about why dark circles are more noticeable when we’re tired is that our blood vessels get bigger. When you’re tired, your body makes more cortisol, a hormone that increases blood flow and makes blood vessels larger. Another reason could be that blood collects under your eyes when you lie down all night.
Eye bags haven’t been studied as much, but they seem to be linked to getting older. People used to think that as we age, the fat under our eyes moves to other parts of the body. However, a study in 2008 found that the fat under our eyes actually increases as we age. This means older people might have more noticeable eye bags, even if they’re not tired.
When you’re tired, eye bags can look worse because water can build up in the fatty tissue under your eyes. Eating a lot of salty food or having allergies can also cause this.
Gravity affects us as we age, causing tissues to droop over time. To help with this, experts suggest not lying flat in bed. Instead, try propping your head up a bit to reduce the effect of gravity on your eye bags.
Thanks for joining me on this exploration of why we get dark bags under our eyes. If you have any big questions you’d like answered, feel free to share them. See you next time!
Create a chart comparing dark circles and eye bags. Include factors like causes, appearance, and any differences in how they develop. Use colors and drawings to make your chart visually appealing. This will help you understand the differences between the two.
Pair up with a classmate and role-play a scenario where one of you is a doctor and the other is a patient concerned about dark circles and eye bags. Discuss possible causes and suggest lifestyle changes or remedies. This activity will help you practice explaining scientific concepts in everyday language.
Conduct a simple experiment to see how gravity affects fluid retention under your eyes. Lie flat for a few minutes, then prop your head up and observe any changes. Record your observations and discuss how gravity might play a role in the appearance of eye bags.
Research how genetics and skin thickness can influence the appearance of dark circles. Create a short presentation or poster to share your findings with the class. This will deepen your understanding of the biological factors involved.
Work in groups to create a skit that shows how lifestyle choices like sleep, diet, and stress management can affect the appearance of dark circles and eye bags. Perform your skit for the class to demonstrate how these factors are interconnected.
Sure! Here’s a sanitized version of the transcript:

Hi, I’m Craig, and this is Mental Floss on YouTube. Today, I’m going to answer a big question: “Why do we get dark bags under our eyes when we’re tired?”
Dark circles and eye bags are actually two different things. If you get dark circles under your eyes, genetics and tiredness play a role. As for bags, they are caused by a combination of factors, which we will discuss after this introduction.
Let’s get started! First, let’s talk about what’s happening under your eyes. The skin in that area is very thin and covers muscle, fatty tissue, and blood vessels. The appearance of darkness can be influenced by skin color and thickness, as well as genetics.
One popular theory as to why dark circles stand out more when we’re tired is that blood vessels expand. When someone is tired, cortisol production increases, leading to more blood flow and larger blood vessels. Another possibility is that blood accumulates in that area from lying down all night.
Now, what about the bags? This area hasn’t been extensively studied yet, but there seems to be a correlation with age. It was once believed that as people age, the fat under the eyes shifts to different areas of the body. However, a study from 2008 showed that the fat under the eyes actually increases in volume with age. Therefore, older individuals may have more noticeable bags under their eyes, regardless of tiredness. However, tiredness can make them more prominent because water can accumulate in the fatty tissue under the eyes. This can also happen after consuming a lot of salt or due to allergies.
Gravity also plays a role over time. As we age, tissues may begin to droop. Experts recommend not lying flat in bed to help mitigate this effect.

Let me know if you need any further modifications!
Dark Circles – Dark circles are the shadows or discoloration that appear under the eyes, often due to tiredness or lack of sleep. – Example sentence: After staying up late to study, Maria noticed dark circles under her eyes the next morning.
Eye Bags – Eye bags are the mild swelling or puffiness under the eyes, often caused by fluid retention or aging. – Example sentence: When John didn’t get enough rest, he noticed eye bags forming under his eyes.
Skin – Skin is the outer covering of the body that protects it from external factors and helps regulate temperature. – Example sentence: The skin is the body’s largest organ and plays a crucial role in protecting us from germs.
Genetics – Genetics is the study of heredity and how traits are passed from parents to offspring through genes. – Example sentence: Genetics can influence many aspects of our health, including our risk for certain diseases.
Blood Vessels – Blood vessels are the network of tubes in the body that carry blood to and from the heart and other organs. – Example sentence: Healthy blood vessels are essential for maintaining good circulation and overall health.
Cortisol – Cortisol is a hormone released by the adrenal glands in response to stress, helping the body manage stress and maintain energy levels. – Example sentence: High levels of cortisol can lead to increased stress and affect the body’s ability to function properly.
Tiredness – Tiredness is the feeling of needing rest or sleep, often resulting from physical or mental exertion. – Example sentence: Tiredness can affect concentration and make it difficult to focus on schoolwork.
Gravity – Gravity is the force that pulls objects toward the center of the Earth, affecting how blood and fluids move in the body. – Example sentence: Gravity causes blood to pool in the lower parts of the body when standing for long periods.
Fatty Tissue – Fatty tissue is a type of body tissue that stores fat, providing energy and insulation for the body. – Example sentence: Fatty tissue helps keep the body warm and stores energy for later use.
Allergies – Allergies are the body’s immune response to certain substances, which can cause symptoms like sneezing or itching. – Example sentence: People with allergies may experience symptoms like sneezing and itchy eyes when exposed to pollen.
