Huberman Lab · How to Improve Your Memory & Cognitive Function at Any Age | Dr. Alan Castel · 13 Jul 2026 podcast

We know a lot of memory formation happens when you're sleeping.

We know as we get older, our sleep quality tends to decline, even if our quantity tends to increase.

So I think just knowing that there are some things we can do, and I'm using physical exercise as the example, and it doesn't have to be the extreme version, walking, dancing, a lot of people enjoy being outside.

That can be incredibly important to offset some of the things we do know can lead to dementia.

You know, in this group, I think it's really 30 to 40 minutes and there's nothing special, certainly about walking, but it's something where you can randomly assign people to either walk or engage in stretching.

So if you're biking, if you're swimming, if you're dancing, any of these things can be beneficial.

But here it's, you know, you can randomly assign people to walk and it should be at a rate where you're, you know, there's research showing that the people who walk slightly faster actually live longer.

So, you know, you're not sure exactly.

Could certainly be that.

And a lot of this research, it's tough to do aging research because it's hard to randomly assign people to certain conditions.

But I think as a psychologist, knowing that you have a little bit of control over the process is important.

And I think most people, when they talk about aging, they're so worried about dementia and Alzheimer's disease as a specific form.

But balance is even more important, I think.

And most people aren't even aware of their balance.

So one in four people over the age of 65 will experience a fall.

And that fall can be very detrimental.

You can break your hip, your collarbone.

Often you're getting up at night more frequently, you trip over a carpet or a rug.

And if you're in bed, just recovering from these falls, you're not walking, your hippocampus is shrinking.

If you ask people, how's your balance?
