Ni dung bài nghe
Host: Welcome to another episode of healthiness. Today, I'm joined by Dr. Dorothy
Allen. She's here to discuss her new book “Forever young”.
Dr. Dorothy Allen: Thanks for having me.
Host: Let's get to it. My listeners want to know what they can do to have a healthier life.
Dr. Dorothy Allen: I think the most important thing is to get enough sleep.
Host: How much sleep do you think people need? .
Dr. Dorothy Allen: In my opinion, you need to give yourself seven to nine hours in bed
each night and research supports that.
Host: My teenage son always wants to sleep in on the weekends and I try not to let him
get too much sleep. Do teens need more sleep?
Dr. Dorothy Allen: Especially important for teenagers because their brains and bodies are
developing. Early morning sleep helps us prepare our mind which helps us manage our
feelings and avoid getting too stressed.
Host: Wow. How about fitness?
Dr. Dorothy Allen: It's a mix of diet and exercise. You need to make sure you eat enough
meat and vegetables to have a balanced diet and avoid eating too much added sugar
Host: And exercise?
Dr. Dorothy Allen: I believe you need to decide if you want to focus on lifting weights or
improving your heart health. Spend three days a week on the one you want to focus on
and two days on the other then give yourself two days to chill out and keep a healthy
social life.
Host: Can you tell our listeners more?

harmful to our health.

rest and recover.

if we play too much, it will be harmful to the eyes.

B: No. I believe we do not need to lift weights every day because doing so can result in
soft tissue injury or even a bone fracture.

from studying.
