But that
sleep
is a missing piece in the explanatory puzzle of aging and Alzheimer's is exciting because we may be able to do something about it.
And one way that we are approaching this at my
sleep
center is not by using sleeping pills, by the way.
Now if you apply this stimulation during
sleep
in young, healthy adults, as if you're sort of singing in time with those deep-sleep brainwaves, not only can you amplify the size of those deep-sleep brainwaves, but in doing so, we can almost double the amount of memory benefit that you get from
sleep.
Can we restore back some healthy quality of deep sleep, and in doing so, can we salvage aspects of their learning and memory function?
So that's an example of
sleep
for your brain, but
sleep
is just as essential for your body.
We've already spoken about
sleep
loss and your reproductive system.
Or I could tell you about
sleep
loss and your cardiovascular system, and that all it takes is one hour.
Now, in the spring, when we lose one hour of sleep, we see a subsequent 24-percent increase in heart attacks that following day.
In the autumn, when we gain an hour of sleep, we see a 21-percent reduction in heart attacks.
But as a deeper dive, I want to focus on this:
sleep
loss and your immune system.
So here in this experiment, you're not going to have your
sleep
deprived for an entire night, you're simply going to have your
sleep
restricted to four hours for one single night, and then we're going to look to see what's the percent reduction in immune cell activity that you suffer.
That's a concerning state of immune deficiency, and you can perhaps understand why we're now finding significant links between short
sleep
duration and your risk for the development of numerous forms of cancer.
In fact, the link between a lack of
sleep
and cancer is now so strong that the World Health Organization has classified any form of nighttime shift work as a probable carcinogen, because of a disruption of your sleep-wake rhythms.
So you may have heard of that old maxim that you can
sleep
when you're dead.
There's a simple truth: the shorter your sleep, the shorter your life.
Short
sleep
predicts all-cause mortality.
And if increasing your risk for the development of cancer or even Alzheimer's disease were not sufficiently disquieting, we have since discovered that a lack of
sleep
will even erode the very fabric of biological life itself, your DNA genetic code.
So here in this study, they took a group of healthy adults and they limited them to six hours of
sleep
a night for one week, and then they measured the change in their gene activity profile relative to when those same individuals were getting a full eight hours of
sleep
a night.
Now those genes that were switched off by a lack of
sleep
were genes associated with your immune system, so once again, you can see that immune deficiency.
In contrast, those genes that were actually upregulated or increased by way of a lack of sleep, were genes associated with the promotion of tumors, genes associated with long-term chronic inflammation within the body, and genes associated with stress, and, as a consequence, cardiovascular disease.
There is simply no aspect of your wellness that can retreat at the sign of
sleep
deprivation and get away unscathed.
Sleep
loss will leak down into every nook and cranny of your physiology, even tampering with the very DNA nucleic alphabet that spells out your daily health narrative.
And at this point, you may be thinking, "Oh my goodness, how do I start to get better
sleep?
What are you tips for good sleep?"
Well, beyond avoiding the damaging and harmful impact of alcohol and caffeine on sleep, and if you're struggling with
sleep
at night, avoiding naps during the day, I have two pieces of advice for you.
Regularity is king, and it will anchor your
sleep
and improve the quantity and the quality of that
sleep.
Your body needs to drop its core temperature by about two to three degrees Fahrenheit to initiate
sleep
and then to stay asleep, and it's the reason you will always find it easier to fall asleep in a room that's too cold than too hot.
That's going to be optimal for the
sleep
of most people.
Well, I think it may be this: sleep, unfortunately, is not an optional lifestyle luxury.
Sleep
is a nonnegotiable biological necessity.
