Summary: Do you know that a lack of sleep makes weight gain?

The explanation why a lack of sleep causes weight gain is an imbalance in two key appetite-regulating hormones, which is leptin and ghrelin. Leptin is a hormone that sends a signal of full stomach and feel satiated of the food to the brain. In contrast, ghrelin sends a signal of hunger to the brain. These two hormones do not work properly when we do not have enough sleep. In particular, a lack of sleep decrease amounts of leptin so you will not feel satiated of the food. Also, increasing the level of ghrelin due to insufficient sleep causes that you will feel hungry constantly and want to eat more foods.

Moreover, the reason that you gain weight when you do not have enough sleep is not only hormones but also a change in what you want to eat. Especially, a lack of sleep will change to preferences of high-calorie food and too sweet food. For example, we prefer hamburgers, juice that includes a lot of sugar. What's more, the relationship between sleep and food is influenced each other. This means that eating bad health foods leads to worse sleep quality and a lack of sleep.

Therefore, if you will care about weight, let's thinking sleep to help control your weight and improve your health.

Summary: form memories, it’s important to strengthen neural connections through a process called long-term potentiation. The three main causes of memory loss are: 1. changes in the brain due to aging,2 . stress and lack of sleep, and 3. mental health conditions such as depression.

In addition, the video highlights that memory is formed in stages from sensory memory to short-term memory, and finally to long-term memory. Repeating information and linking it to what you already know helps strengthen those memories.

Forgetting is also a natural brain process that helps remove unnecessary information and keep the brain efficient. The hippocampus plays a major role in memory formation, and emotional experiences tend to be remembered more clearly due to increased brain activity.

To prevent memory decline, it’s essential to sleep well, reduce stress, and care for your mental well-being.

Vocabulary words:

Decline: The loss of momentum of things and people, becoming weak, or declining.

Chronic: Symptoms and conditions persist for a long time, difficult to cure, or slow to progress.

Summary: The video starts by relaying a 2019 study participants who were encouraged by early success learned better in the next round, while those forced to fail struggled despite equal information.

Major barriers to learning from mistakes include:

•The emotional pain of failure, which threatens self-esteem and can stop the brain from processing new information.

•Failure is often ambiguous. It’s hard to figure out why something went wrong, making it tougher to learn from it.

How acceptance varies by skill level:

•Beginners often crave praise to stay motivated.

•Advanced learners prefer critical feedback because they’re invested in improvement.

Positive learning strategies encouraged include:

•Cultivating a growth mindset.

•Focusing on self-talk—framing experiences as “learning opportunities” rather than failures.

•Leveraging successes: replicate what works, rather than dwelling only on missteps.

In brief, the video emphasizes that while failure can feel painful and unhelpful, developing resilience, understanding the underlying causes, and using positive framing can turn errors into powerful lessons.

Vocabulary words:

ambiguous: The content is hard to grasp and unclear.

crave: To desire fervently.

Emma Watson was appointed six months ago to speak about feminism.　She notes fighting for women's rights is often wrongly seen as man-hating.　Feminism means equal rights and opportunities for men and women politically, economically, and socially.　From childhood, she questioned gender stereotypes (e.g., being called bossy for leading).　She experienced sexualization by media and saw friends dropping sports to avoid appearing "muscley."　She decided to identify as a feminist because it seemed straightforward.　However, feminism has become unpopular; some women avoid the label as it’s seen as too strong or anti-men.

Emma believes in equal pay, bodily autonomy, political representation, and social respect for women.　No country has yet achieved full gender equality worldwide

summary Arnav Kapur talks about a future where human thought and AI are directly connected in this TED Talk. He is researching technology that allows communication with AI by 'thinking only' without speaking. This device works in such a way that the AI understands the words we form in our minds and responds accordingly. For example, by simply thinking, 'What time is it now?' without speaking it aloud, the AI reads that question and answers it right in your ear. If such technology is realized, we will be able to connect seamlessly with AI without using external devices like smartphones or keyboards.

Summary: The average human being is made up of 55~60% water. A newborn baby is 75 percent water, similar to a fish.

The role of water in our bodies is to manage body temperature and nourish the brain. Water not only makes up our blood, but also three-fourths of our adult brain and heart. In other words, we are made of water.

We lose 2,3 L of water every day from sweating, urinating and defecating, and breathing. Because these functions are essential to us, we need to compensate for the loss of water. Persistent dehydration leads to loss of energy, mood, skin moisture, and vision loss. It also leads to excess water, headaches, vomiting, and death.

Finally, the amount of water that should be consumed is 2.5~3.7 L per day for men and 2~2.7 L per day for women; we can also hydrate ourselves from coffee, tea, and fruits that contain caffeine.

Vocabulary:

dehydration (n): Dryness resulting from the removal of water.

impairment (n): Functional decline or damage

Discussion:

#1 How much water do you drink a day?

#2 What do you drink most often besides water?
