In this brief health advice segment, Dr. David Perlmutter cautions against relying on prescription sleep medications, explaining that they do not provide the deep, restorative stage 3‑4 sleep needed for optimal brain function and can linger in the body, impairing next‑day performance. He offers practical sleep‑hygiene strategies: avoid caffeine after noon because it stays active longer than expected; schedule exercise earlier in the day rather than in the evening, as late‑day workouts can delay sleep onset; and discuss all current medications with a physician, since many drugs can disrupt sleep and may be better taken in the morning. The overall message is to adopt natural, lifestyle‑based approaches to improve sleep quality.

You know, the easy way out seems to be that you just tell your doctor, gee, I'm not sleeping well, and he or she would then write you a prescription for a sleep drug. That's pretty much the way of the world these days, and in reality, that idea is flawed on 2 counts. First, the depth and restorative ability of the sleep that you get on a drug is definitely not what it would be if it were natural sleep. That is, you're not really getting into the deeper levels of stage 3 and 4 sleep that are so restorative, giving you back that good brain chemistry so that the next day you're on the ball and ready to function. And the second thing is we clearly know that many of the medicines used will remain in your system for a lot longer than just the nighttime that you think that they're helping you. We've seen new reports of many of the most popular so-called sleep aids Actually compromising a person's function the next morning and well into the next day. So what can you do to help yourself sleep? Well, you want to avoid drinking caffeine any later than, let's say, noontime. Caffeine can actually remain active in your system for a lot longer than you think. Exercise is very, very helpful. One of the first things we recommend for people in terms of helping them feel tired at night and get to sleep But it's good to keep in mind that you shouldn't exercise in the evening. A lot of people say, well, that's the only free time I have. And what I, what I say to them is, let's look at this a different way. Let's do the exercise on the front end early in the morning, and that way when you get home in the evening, you can, instead of exercising in the evening, you can go to sleep a little bit earlier. Exercise is exciting no matter how you slice it generally, and it should be. But doing something like that late in the evening can tend to keep you from having the ability to go to sleep. And finally, I think it's a good thing to have a discussion with your physician about the various medications that you may be taking. Many medications actually can interrupt sleep and are oftentimes better taken in the morning. It's a good discussion to have with your doctor.
