Sweating, also known as perspiration, is a crucial process for our bodies. It helps us cool down by absorbing heat and then evaporating. It’s normal to sweat more when it’s hot outside or when we’re exercising. However, some people sweat a lot even when they’re not doing much. This is called hyperhidrosis, where the sweat glands work overtime and produce more sweat than needed. Things like caffeine in coffee and nicotine in cigarettes can also make people sweat more. Interestingly, men usually sweat more than women.
Antiperspirants help stop sweat from reaching the skin. There’s a special type of sweat gland called the apocrine gland that makes sweat containing fats and proteins. Bacteria on our skin eat these substances, which can cause body odor. To fight this, we use deodorants or antiperspirants. Deodorants make it hard for bacteria to grow, while antiperspirants create a gel-like barrier that blocks sweat. However, some of these products might have harmful ingredients, so it’s best to use them carefully.
Penguins are amazing at living in cold places without getting their feet frozen. They have a special trick called countercurrent heat exchange. In their feet, the arteries and veins are wrapped closely together. When warm blood flows to their feet, it transfers heat to the colder blood returning to the body. This helps keep their feet warm enough to avoid frostbite.
Pimples happen because of the sebaceous glands in our skin, which produce an oily substance called sebum. Sometimes, our pores get blocked by dead skin cells, causing sebum to build up. This can lead to bacteria growth and infection. Our immune system then sends blood and immune cells to the area, causing inflammation and forming a pimple.
Our bodies generate heat through muscle movement and metabolism, which helps keep us warm. However, some people feel cold all the time due to conditions like hypothyroidism, where the thyroid gland doesn’t work properly, slowing down metabolism and reducing heat production. Another condition is Raynaud’s disease, where stress or cold causes the arteries in the extremities to narrow, reducing blood flow. Other factors like low muscle mass, low iron levels, and smoking can also make someone feel cold.
Conduct a simple experiment to understand how sweating helps cool the body. Fill two balloons with water and wrap one in a damp cloth. Place both balloons in a sunny spot and observe which one stays cooler. Discuss why the damp cloth helps keep the balloon cooler, similar to how sweat cools our skin.
Create a model of an antiperspirant using clay or playdough. Explain how it works to block sweat from reaching the skin. Discuss the differences between deodorants and antiperspirants and why it’s important to choose products carefully.
Learn about countercurrent heat exchange by creating a simple model using straws and warm water. Wrap two straws together, one with warm water and the other with cold water, and observe how the temperatures change. Discuss how this helps penguins keep their feet warm.
Create a poster that explains how pimples form and how to prevent them. Include tips on skincare routines and the importance of keeping pores clean. Share your poster with the class to help everyone understand how to take care of their skin.
Participate in a relay race where each team member must complete a physical activity like jumping jacks or running in place. Discuss how muscle movement generates heat and why some people might feel cold more often. Explore ways to stay warm through exercise and proper nutrition.

**It’s AumSum Time!**
Hi guys! Can you guess the title of my next video? Hurry up and write your guess in the comments section below.
**Why do some people sweat more than others?**
Sweating, or perspiration, is a very essential process. It helps regulate our body temperature by absorbing heat and evaporating. While it’s normal to sweat more on hot days or during exercise, some people experience excessive sweating even under normal conditions. This condition is known as hyperhidrosis, where the sweat glands overreact and produce more sweat than necessary. Additionally, substances like caffeine in coffee and nicotine in cigarettes can increase sweating. Interestingly, men tend to sweat more than women.
**How do antiperspirants work?**
Antiperspirants work by blocking sweat from reaching the skin. A type of sweat gland called the apocrine gland produces sweat that contains fats and proteins. Bacteria on our skin consume these substances, leading to body odor. To combat this, we use deodorants or antiperspirants. Deodorants create an environment that is unfavorable for bacteria, while antiperspirants form a gel-like substance that blocks sweat. However, some deodorants and antiperspirants may contain harmful components, so it’s advisable to use them in moderation.
**Why don’t penguins’ feet freeze?**
Penguins have adapted to cold climates to prevent their feet from freezing. One adaptation is a mechanism called countercurrent heat exchange. In their feet, arteries and veins are closely wrapped together. As warm blood flows to the feet, heat is transferred to the colder blood returning to the body, helping to keep the feet warm enough to avoid frostbite.
**Topic: Pimples**
**Why do we get pimples?**
Pimples are caused by the activity of sebaceous glands in our skin, which produce an oily substance called sebum. Sometimes, pores can become blocked by dead skin cells, leading to an accumulation of sebum and the growth of bacteria, which can cause infection. Our immune system responds by sending blood and immune cells to the area, resulting in inflammation and the formation of a pimple.
**Why are some people always cold?**
Humans generate heat through muscle movement and metabolism, which helps maintain body temperature. However, some people may feel cold due to conditions like hyperthyroidism, where the thyroid gland does not function properly, leading to a slower metabolism and less heat generation. Another possibility is Raynaud’s disease, where stress or cold exposure causes narrowing of the arteries in the extremities, reducing blood flow. Other factors such as low muscle mass, low iron levels, and smoking can also contribute to feeling cold.
