Now, listen to Part Two of the interview.
W: Well. It’s hard, you know.
M: So, this isn’t going to be an overnight change.
W: Trying to learn to sleep is a long process and it takes a lot of dedication and you have to stick with it.
M: And so this is someone who’s going to really stick with the program. You tell them from the beginning that this is not going to be like a boot camp, isn’t it?
W: It isn’t like a boot camp. It’s a lot like quitting smoking or drinking, whatever else. You have to really put the time in it. If people are ready, it would work, though not easy.
M: Let’s talk about something you call "sleep hygiene"—the tips you say anyone can use to improve their habits. (6-1) No. 1, "Make sleep a priority".
W: Well, that’s hard. I mean we have so many responsibilities in the world. But if you find that your sleeplessness is disturbing the way you feel during the day, you have to make it a priority.
M: And then(6-2/7-1) "Make your bedroom comfortable".(7-2) Are we talking about mattress and pillow or lightings?
W: Well, both! I mean all of the above need to be comfortable and cozy.(7-3) You shouldn’t have your computer in your bedroom or be paying your bills while you are lying in bed. It ought to be comfortable and inviting.
M: We all know that caffeine will keep us awake. But you say(6-3) " Don’t have caffeine after lunch". Someone’s going to bed at nine or ten. I mean does it really stay with them that long?
W: Caffeine can stay with you up to 10 hours. And so you have to make sure you stop if it’s bothering you and if you have trouble sleeping. You shouldn’t have caffeine after lunchtime.
M: I’m reading the next tip:(6-4) "Don’t take a nap during the day. "
W: Well.(8-1) I think naps are good. If they are people who have a crazy schedule and can’t get to sleep, and maybe tonight have something else that they have to do, a nap is good. It’s going to revive them.
M: Do you like a twenty-minute nap or two-hour nap? I mean is too much bad?
W:(8-2/9) Too much is too bad. You have to keep it less than 45 minutes. If not, you will end up getting deep sleep and wake up feeling worse instead of better.
M: Alright. Getsy, thank you for being here with us.
