Nobel prize winners’ quest for answers to sleep mysteries

- Esther J. Cepeda Columnist

As I type this column, I am exhausted from sleep deprivatio­n — a pretty standard state of being for me. Despite a lifetime of boring, monkish routine and impeccable sleep habits, my circadian rhythm has always been syncopated rather than regular or in any kind of harmony.

I’ve suffered from periodic bouts of insomnia for nearly all of my life.

As a young child, I would cry myself to sleep at 2, 3 or 4 in the morning and then feel completely wrecked at school. It drove my teachers absolutely crazy that I was half-asleep and headachy most of the time.

No, it’s not my thyroid, or narcolepsy. All the usual medical suspects have been ruled out time and again — I simply come from a long line of restless sleepers. Such medication­s as sleeping pills either don’t work or give me nasty side effects. Meditation helps, but only to a point.

My best hope is for science to figure this all out in time for sleep deprivatio­n to not finally get me with its increased chance of obesity, Type 2 diabetes and possibly even Alzheimer’s disease.

We only understand how the delicate cycles of sleep and wakefulnes­s are related to physical and mental well-being because of years of research.

Last week, three of the researcher­s behind some of these insights got an acknowledg­ment for unraveling a few of sleep’s deepest mysteries.

Jeffrey C. Hall, Michael Rosbash and Michael W. Young won the Nobel Prize in physiology or medicine for their pioneering work in figuring out how the body’s sleep/wake rhythms regulate critical functions like sleep, hormone levels, blood pressure and body temperatur­e.

Using fruit flies as a “model organism,” the trio of scientists isolated genes they dubbed “period,” “timeless” and “doubletime” that regulate the daily circadian rhythms.

The researcher­s found that these genes encode a protein that accumulate­s in cells during sleep at night, which then degrades during the day.

Subsequent­ly, the researcher­s identified additional protein components of this machinery inside the cells. Eventually they found that these “biological clocks” function by the same principles in cells of other multicellu­lar organisms, including humans.

This recognitio­n of achievemen­t in their field comes after three decades of their intimate study of the humble fruit fly, which yielded many of the facts about our bodies’ daily rhythms — like when we have the best coordinati­on, the highest body temperatur­e and the fastest reaction times — that so many breakthrou­ghs in understand­ing the importance of sleep are based on.

When you think about it, the most stunning part is that these scientists dedicated their careers to something as elemental and mysterious as sleep.

“I just thought it was a terrific problem and maybe the toughest thing I could try to tackle,” Young told Adam Smith, the chief scientific officer of Nobel Media, “because it was behavior; you know, what could we learn about a fairly complicate­d behavior that we all exhibit, which was most easily represente­d by sleep/wake cycles. And frankly I thought we might find out maybe a little bit. I never thought we would really understand what the motor behind this was, at the time. We were very lucky, we managed to find genes that fit together like puzzle pieces to explain how this thing worked.”

The next frontier in sleep science is applying this knowledge about sleep rhythms to the quandaries of preventing obesity and mental health disorders and how to optimize everything from exercise to the uptake of vitamins and medication­s.

Selfishly, I’m hoping that it won’t take another 30 years to figure out how to get reluctant creatures of the night to slumber.

But I’m perfectly willing to wait for whatever scientific discoverie­s can make me sleep way better than I did when I was a baby.
