0Erinome: Hello dear friends, welcome back to our podcast. Today we are going to talk about a very interesting topic - how our mind can affect our body.
Enceladus: Wow, that sounds amazing. You mean, just by thinking, we can change our health?
Erinome: Yes, exactly. There is a lot of new research about this. For example, there is something called the "placebo effect". You know that?
Enceladus: Um, I think I heard about it. Is it when a patient feels better after taking a pill with no medicine, just because they believe it will work?
Erinome: That's right! A study published in Nature Medicine showed something similar. They trained people to activate a specific part of their brain.
Enceladus: Haha, train the brain? How?
Erinome: They used a technique called "neurofeedback". People lay in a brain scanner and saw a score. They tried different mental strategies to make the score go up.
Enceladus: What kind of strategies?
Erinome: Oh, like thinking about happy memories, or imagining good things. They learned to activate areas called the ventral tegmental area and nucleus accumbens.
Enceladus: Those names are hard! But why do this?
Erinome: After the training, they gave all the people a hepatitis B vaccine. They found that people who activated the ventral tegmental area better had more antibodies.
Enceladus: Antibodies? So their immune system was stronger?
Erinome: Yes! Their bodies fought the vaccine better. This shows a link between brain activity and the immune system.
Enceladus: That's incredible. So a positive mind can really make the body stronger?
Erinome: It seems so. The study says it's like an evolutionary thing. When we feel rewarded, maybe our immune system gets ready for danger.
Enceladus: Interesting. But this is just for vaccines, right?
Erinome: The researchers say it could be a tool to help, but not replace real medicine. We need more tests.
Enceladus: I see. But there are other stories too, right? Like people with serious illness living longer because of a strong mind.
Erinome: Oh yes. The news talked about a professor from Taiwan. She had cancer and was told she had only six months to live.
Enceladus: Oh no, that's sad.
Erinome: But she changed her mindset, her diet, and did healthy training. She lived for more than thirty extra years!
Enceladus: Wow, that's powerful. So belief is very important.
Erinome: Exactly. Another story is about an old Buddhist monk. He had cancer at 80 and was told he had five years left.
Enceladus: And then?
Erinome: He did not worry too much. He lived to 107!
Enceladus: Haha, amazing. So managing your thoughts and emotions is a secret to long life.
Erinome: It seems so. There was even a fun experiment about eyesight.
Enceladus: Eyesight? How can mind change that?
Erinome: Normally, the eye chart has big letters at the top and small ones at the bottom. So people expect to see less at the bottom.
Enceladus: Right.
Erinome: In the experiment, they flipped it. Small letters on top, big ones at the bottom. So people expected to see better at the bottom.
Enceladus: And what happened?
Erinome: Their real eyesight got better! They could see letters they couldn't see before.
Enceladus: No way! That's like magic.
Erinome: It's the power of expectation. If you believe you will see better, your body might help you see better.
Enceladus: This makes me think about getting old. Many people think old means weak.
Erinome: But that's not always true. There was a famous experiment with old people. They lived for a week like it was 20 years ago.
Enceladus: How?
Erinome: They stayed in a place made to look like 1959. They listened to old music, read old newspapers, talked about old news.
Enceladus: That sounds fun. What was the result?
Erinome: After one week, their bodies got better. Their memory, hearing, even their walking improved. Especially the group that really "lived" in the past.
Enceladus: So, if you believe you are young, your body acts younger?
Erinome: Yes! The mind can lead to physical changes. Aging is not just about the body, it's also in the mind.
Enceladus: But what about bad times, like during the pandemic? Many people felt stressed.
Erinome: That's a good point. Another article talked about normal psychological changes during COVID-19.
Enceladus: Like what?
Erinome: When we face big stress, we go into a "stress response". Our emotions, body, thoughts, and behavior can change.
Enceladus: For example?
Erinome: Emotionally, we might feel more anxious, fearful, or sad. Physically, we might have stomach pain, or no appetite.
Enceladus: I felt that. My sleep was not good.
Erinome: That's a common change. Our thoughts can change too. We might worry more, or find it hard to focus.
Enceladus: Yes, I couldn't decide what to eat sometimes, haha.
Erinome: And our behavior. We might wash hands too much, or avoid going out.
Enceladus: But the article says these changes are normal, right?
