Transcript

  • 00:00- My name is Brienne Miner, and I'm assistant professor
  • 00:03at Yale University in the section of geriatrics.
  • 00:05I've also done training in sleep medicine.
  • 00:08And today, I'm gonna talk about sleep and aging
  • 00:11and I'm gonna cover the different ways
  • 00:13that sleep might change as we age,
  • 00:15all of the different factors
  • 00:17that might be causing sleep problems as we get older,
  • 00:20and when you should speak with your doctor
  • 00:22about a sleep problem.
  • 00:26Most people think that as you get older you need less sleep.
  • 00:30But if we look at how much sleep is recommended,
  • 00:34it really doesn't change from middle to older age.
  • 00:37So middle-aged adults,
  • 00:39according to the National Sleep Foundation,
  • 00:41should be getting, the real sort of sweet spot
  • 00:44is seven to nine hours.
  • 00:46And in adults 65 and older it's seven to eight hours.
  • 00:50So you know, we do recognize that a little bit
  • 00:53on either side, so five hours or up to nine hours
  • 00:56may be appropriate.
  • 00:57But I think the interesting thing is that
  • 01:00if you compare middle-aged and older age adults,
  • 01:03the recommendation for how much sleep you should be getting
  • 01:05is the same.
  • 01:09As we get older, there are probably multiple things going on
  • 01:14at the same time that might impact our sleep.
  • 01:16So I like to think about what medical conditions
  • 01:20or medications a patient of mine might be taking
  • 01:22and how that might affect their sleep.
  • 01:24Medical conditions could certainly cause pain
  • 01:27or other sleep disruptive symptoms.
  • 01:29People can be on medications
  • 01:31that could make them very sleepy during the day.
  • 01:35Those medications could make it hard for them
  • 01:37to sleep at night.
  • 01:38Or interestingly, those medications might cause
  • 01:42or worsen an underlying sleep disorder.
  • 01:44In terms of behavioral factors,
  • 01:47we like to think about having good sleep hygiene,
  • 01:50having good behaviors around sleeping.
  • 01:53And so those are basic things like going to bed
  • 01:55at the same time every night,
  • 01:57getting up at the same time every morning,
  • 02:00avoiding napping during the day,
  • 02:02especially if you have trouble sleeping at night,
  • 02:04and a big one that I like to touch on
  • 02:06is what substances might contribute to sleep.
  • 02:09So alcohol, especially as you get older,
  • 02:13can cause more problems with sleep
  • 02:16because your body is not as good at metabolizing alcohol
  • 02:19as you get older, and you can't drink the same amount
  • 02:24in your older age that you could in your middle age.
  • 02:26Caffeine, same story as alcohol, and nicotine as well
  • 02:30can make it hard to fall asleep,
  • 02:32can make it hard to stay asleep.
  • 02:34Other things like being socially isolated,
  • 02:38I think we've all been thinking a lot about that
  • 02:39especially in the setting of COVID.
  • 02:42So why does social isolation cause problems with sleep?
  • 02:45Well, you're less physically active during the day
  • 02:49and that can make it harder
  • 02:50to have a normal sleep/wake schedule.
  • 02:53And those social interactions are actually also
  • 02:56very important for giving cues to our body
  • 02:59to help help us maintain a normal sleep/wake rhythm.
  • 03:01And then I would be remiss if I didn't mention what we think
  • 03:04about a lot in sleep medicine, which is that almost all
  • 03:07of the sleep disorders that are out there
  • 03:10become more common as we age.
  • 03:12So people in their older age could have
  • 03:15multiple things going on at the same time.
  • 03:19One of the major changes that's normal
  • 03:22and is not necessarily a sign of disease
  • 03:25is that many older people prefer to go to bed earlier
  • 03:29and wake up earlier.
  • 03:31So as opposed to going to bed at maybe say 10 or 11 o'clock,
  • 03:34some people may have a preference to go to bed at seven
  • 03:38or 8:00 PM, and that's because there's a a change
  • 03:42in the timing of melatonin release from our brain.
  • 03:45So melatonin is sort of setting that time for us.
  • 03:50And in many older people, our brain releases melatonin
  • 03:53in an earlier time.
  • 03:55So again, it's not necessarily a problem
  • 04:00except that many people don't like to go to bed at 7:00 PM
  • 04:04or wake up at three or four o'clock in the morning.
  • 04:08So I would say, if your preference is to go to bed
  • 04:11at 8:00 PM, there's no problem with that.
  • 04:15But you wouldn't want to, or it would be normal then
  • 04:19to wake up at three or four o'clock in the morning.
  • 04:22That's still a normal amount of sleep.
  • 04:24So there's actually no problem with that
  • 04:25unless it's a problem for your schedule.
  • 04:30So some important takeaways about sleep as we age,
  • 04:34are first that the timing of sleep may change.
  • 04:37So older adults may find that they have a preference
  • 04:40to go to bed earlier and therefore wake up earlier.
  • 04:45The amount of interruptions or arousals from sleep
  • 04:49become more frequent as we get older.
  • 04:51But as long as they're brief and you're able
  • 04:53to get back to sleep, that's not a problem.
  • 04:55And then finally, I would say there could be
  • 04:57a lot of things contributing to sleep problems in older age,
  • 05:02but I look at that as a glass half full kind of person.
  • 05:05When somebody comes to me with a sleep problem,
  • 05:07I think there are a lot of things we could do to help sleep,
  • 05:10whether it has to do with medical conditions, medications,
  • 05:15behaviors or treating an underlying sleep disorder.
  • 05:18So I think that's an important takeaway.
  • 05:20If you do have a sleep problem,
  • 05:22you should talk to your doctor,
  • 05:24you should get an evaluation, and there might be
  • 05:26a lot of options for you that don't necessarily mean
  • 05:28having to take another medication.
