W: Mr. Kim. Lots of people are suffering from being unable to sleep, including me.
M: Well, you must be feeling bad, twisting around, and trying to find a comfortable position. But you’re probably only making matters worse.
W: Really. I thought changing positions would help.
M: (1)That’s not right. What happens is that your heart rate actually increases, making it more difficult to relax. You may also have some bad habits that contribute to the problem.
W: Really? Like what?
M: (2)Do you rest frequently during the day? Do you get virtually no exercise, or do you exercise too much late in the day? Do you sleep a lot or sleep late on weekends?
W: You’re talking about me! I’m leading a life like that. I guess lots of people do like this.
M: (2)Haha! Any of these facts might be leading to your insomnia by disrupting your body’s natural rhythm.
W: What should we do then on those sleepless nights? Should we take some sleeping pills?
M: (3)Don’t bother with sleeping pills: they can actually cause worse insomnia later.
W: I thought sleeping pills would help. (4)What’re your suggestions for our audiences?
M: The best thing to do is to drink milk or eat cheese or tuna fish. They are all rich in amino acid that helps produce a substance in the brain that induces sleep. This substance will help you relax. And you’ll be on the way to get a good night’s sleep.
W: I’m so excited to hear all this. (4)I guess many of us will change our way of life since they have listened to our talk.
M: Your sleeping will become better and better if you insist.
W: I’m sure I will! (4)Thank you much for your advice and thanks for joining us this evening!
M: It’s my pleasure.
