What’s The Easiest Way to Reduce Your Cancer Risk?

By Lee Euler / May 8, 2022

Skimping on sleep has become the American norm. And Americans are paying a terrible price through mounting troubles, including a greater danger of cancer. By some estimates, sleep deprivation is the #1 health problem in America.

Eating yourself to death — that I can understand. Prime rib and Black Forest cake might be worth dying for. The pleasure is undeniable. But wrecking your health because you never get enough sleep? To me, that’s weird! Keep reading and find out what too little sleep could be doing to you…

The wonders of our electrified world have stolen a decent night’s sleep from us. Before electricity, most people went to bed when darkness fell. During the winter, that was early, and people slept a lot. Candles and lamp oil were expensive in a world where the average family made a few hundred dollars a year (if they were lucky). So, the sensible thing to do was go to bed and wake up when the sun rose.

Then came the electric light bulb. Suddenly days could last well past dusk. But it really took television to get us addicted to after dark excitement and mental stimulation. It’s safe to say that, pre-television, everyone got plenty of sleep. Once the tube was ensconced in every home like an altar, millions stayed up to watch the Tonight Show and assorted other late-night distractions. And these days, sleep also loses out to the Internet, e-mail, and who knows what else.

How sleep-deprived are YOU?  

Take this simple five-point test suggested by James Maas, PhD, pioneer in the field of sleep research, sought-after speaker, and author of The New York Times Best Seller book, Power Sleep:

  1. Do you need an alarm clock to wake up in the morning?
  2. Do you hit the snooze button several times before finally dragging yourself out of bed?
  3. Do you sleep in on weekends?
  4. Do you fall asleep the minute your head hits the pillow?
  5. Do you crave a nap to get through the day?

Did you answer “yes” to any of these? If so, consider yourself sleep-deprived. And you’ve got plenty of company. Consider:

  • 43 percent of respondents report that daytime sleepiness interfered with their work and other normal daytime activities.
  • In a “Sleep in America” poll of 1,000 adults, nearly a third said that they need at least eight hours to avoid feeling sleepy the next day. However, their average sleep time was only 6.9 hours on weeknights and 7.5 on weekends.
  • Falling asleep the moment your head hits the pillow is a sure sign of sleep deprivation… a well-rested person takes 15 to 20 minutes to fall asleep.
  • A 4,000-person survey found that only 19 percent were diagnosed with a sleep disorder, yet 74 percent said they got less sleep than they needed. What’s worse is that a whopping forty-six percent said they missed the sleep they needed by at least three hours!

But wait — it gets much worse than just feeling worn out.

Short-term consequences of sleep loss    

Lack of sleep has dramatic effects on your health and quality of life. If you lose one night’s sleep, you’ll be irritable and clumsy the next day. You either feel exhausted, or you feel hyped because you’re running on adrenaline (and caffeine, no doubt).

After a second night’s sleep loss, most people have trouble concentrating and will make mistakes on routine tasks. Three missed nights, and they start to hallucinate and lose grasp of reality.

If you get just a few hours of sleep each night, over time you incur a large “sleep deficit” — and you start to see the above problems, not by losing a whole night at once but by cumulatively losing a little sleep EVERY night.

You can feel the short-term consequences of sleep loss right away. They’re obvious. But it’s the long-term impact on your health that can be devastating (beyond the obvious risks of drowsy driving and workplace accidents).

Hidden long-term risks of sleep debt    

As if the above costs aren’t enough, new studies show that chronic sleep deprivation is one of the biggest predictors of obesity.

Your quality and quantity of sleep dictates the hormonal activity that regulates appetite — via the hormones leptin and ghrelin. Sleep deprivation causes your leptin levels to drop and ghrelin to rise dramatically.

Leptin signals “fullness” so if it’s disrupted, you end up craving food — especially carbs. Ghrelin sets off your hunger pangs.

I think it’s fascinating that sleep correlates with the other bad habits that are killing millions.

In a national study of nearly 10,000 adults, between the ages of 32 and 49 years old, those who sleep less than seven hours were significantly more likely to be obese.

Another study of 18,000 adults found that those who regularly sleep less than four hours per night were 73 percent more likely to suffer from obesity. Wow! Who would have thought losing weight could be easy if you just get more sleep?

Sleep is not only critical to your metabolism, it’s also essential to healthy immune function. In fact, too little sleep can dampen immune function.

Studies show that sleep deprivation adversely affects your white blood cell count and your body’s ability to fight infections. It makes your immune system vulnerable and less able to fight off viruses, bacteria, toxins, and potentially cancerous cells.

Sleep deprivation can cause cancer    

New studies suggest that how you sleep may determine how well your body fights cancer.

In fact, it’s well-known that working the graveyard shift may increase your cancer risk. A number of studies show that women who worked nights for years seem more prone to breast cancer. And men who work the night shift have higher rates of prostate cancer.

Several reports from the Harvard Nurses’ Health Study link insufficient or irregular sleep to an increase in colon cancer and breast cancer.

This is proven in animals as well. When animals have their light-dark schedules reversed, studies show they’re more likely to grow cancerous tumors and die more quickly.

How does insufficient sleep impact cancer?    

Sleep problems affect two hormones that influence cancer cells.

Cortisol regulates your immune system and releases certain natural killer cells that help fight developing cancer cells. Cortisol levels peak at dawn, suggesting sleep’s role. (This is the same stress hormone triggered during anxiety.)

The second hormone is melatonin, produced by your brain during sleep. Scientists think it may have antioxidant properties that help prevent cellular damage leading to cancer.

Melatonin can only be released in total darkness and may cause a reduction in estrogen production. Researchers speculate that experiencing light late at night may interfere with melatonin release, allowing estrogen to rise, and promoting the growth of breast and endometrial cancers.

Melatonin is also the prime suspect in the “shift work theory.” People working in artificial light at night may have lower melatonin levels, raising cancer risk.

Further, certain processes like cell division and DNA repair happen at regular times. If your body does something at an unusual time — like produce insulin in the middle of the night to digest food — a chain reaction of biological mistakes is set up.

Potentially even worse than the graveyard shift is flipping between night and day shifts. Also at risk are frequent long-haul travelers and insomniacs, who experience similar sleep disruption.

You need a dark night’s sleep… eight pitch-black hours every night. So, why don’t people get their eight hours?

In the survey cited above, 65 percent of respondents named stress as a major factor in insomnia. Closely following that, 53 percent said they felt work or school didn’t leave them enough time to sleep.

Six tips for improving your sleep    

  1. Reduce stress as much as possible. Don’t sweat the small stuff!
  2. Put some quiet space between your day and your night. Get to your room 20 minutes before bedtime, and relax with light reading, meditation, or quiet music, keeping the lights low and the atmosphere relaxing.
  3. Complete exercise at least three hours before bedtime.
  4. Get sunshine every day. Your body needs the extremes of light and dark.
  5. Eat properly. Healthy people sleep better. Take your evening meal at least two hours before bedtime, preferably three. Never overeat just before bedtime.
  6. Make your bedroom pitch-black, quiet, and cool. Use black-out curtains. Use ear plugs if there’s street noise or noise from other family members in nearby rooms. The optimal sleep temperature is 60 to 68 degrees Fahrenheit so run the AC if appropriate.

My takeaway    

You may be one of those people who have been sleepy for so very long you don’t know how it feels to be wide awake.

Let the world wait till tomorrow — not your sleep. It is a fundamental health need. Once you truly start sleeping again, you’ll love the joy of sleep’s restoration and rejuvenation, and the energy you’ll have — not to mention its cancer-protective benefits.
