early morning awakening can be avoided by postponing sleep

Relief From Early Morning Insomnia

It may be true that the early bird gets the worm. But there’s no advantage to waking up before the birds—or so I’m told by insomnia sufferers who routinely wake up at 2:30 or 3 a.m. and can’t get back to sleep. It’s depressing to wake up too early night after night.

Here’s why early morning insomnia occurs and how to get your sleep cycle more in sync with daylight and darkness.

Insomnia probably won't be alleviated by offering employee nap rooms

Nap Rooms? Flextime Might Help More

There’s a campaign going to educate people about the importance of sleep. Some companies are responding by installing “nap rooms” where employees can catch a few winks during the workday (or the work night).

But access to a nap room at work would not improve my productivity or my health. Nor would it make me less prone to insomnia. What would help (if I were still going in to work everyday rather than working from home) would be the option to work on a flextime schedule in sync with my body clock. Here’s why:

Electric lighting can be helpful and harmful to sleep

Back to Nature? Not for This Insomniac

Artificial lighting gets a bad rap in stories about sleep these days. Before Thomas Edison invented the light bulb, we’re told, our forebears slept longer than we do today.

There are reasons to think this might be true: Exposure to artificial lighting at night delays secretion of melatonin, in turn postponing sleep. Light at night can also reset the body clock, altering sleep timing and giving rise to circadian rhythm disorders and insomnia.

Advice for how to avoid these problems usually runs along the lines of dimming lights in the evening and getting plenty of exposure to sunlight during the day. Count me as a believer here. But the back-to-nature solutions some are touting? Meh, I’ll pass.

Eating irregular meals, and iron-high snacks at night, is harmful to sleep and health

Eat Right to Sleep Tight

In the late Renaissance, many medical authorities were convinced that digestive processes controlled the duration of sleep. People slept as long as necessary to digest their evening meal.

That proposition fell by the wayside long ago—yet new evidence suggests that the timing of meals does affect our sleep. Particularly in people who are prone to insomnia, eating more regular meals, and eating dinner earlier in the evening, may be important keys to sounder sleep and good health.

Blue light interferes with sleep and melatonin secretion at night but is beneficial during the day

Blue Light's Effect on Sleep? It's Not All Bad

Blue light gets a bad rap these days in articles about sleepy teens. Exposure to blue light in the evening interferes with the secretion of melatonin (a sleep-friendly hormone), pushing circadian rhythms out of whack. This can lead to insomnia or sleep deprivation. Doctors are counseling teens and the rest of us to turn off devices that emit blue light—computers, tablets, and smartphones—in the run-up to bedtime.

This is sound advice as far as it goes. But the story on light is bigger than this simple warning suggests. Knowing how to manage your exposure to blue light can help you steer clear of sleep problems and increase your daytime stamina.

working without natural light has a negative effect on sleep and stamina

Sleep Well Despite Poor Work Conditions

Stressors at work— demanding bosses, looming deadlines, performance reviews, and the like—can fuel insomnia. But low light and the timing of work can also affect sleep. Lack of exposure to sunlight on the job and night or shift work may reduce total sleep time and deprive you of energy in your waking hours.

But you may be able to manage these less-than-optimal work conditions in ways that improve both your sleep and your stamina.

Q&A: What Is Melatonin Replacement Therapy?

I’ve just heard of melatonin replacement therapy, a reader wrote last week to Ask The Savvy Insomniac, and I’m wondering if I should look into it. I’m 61. I never used to have problems with insomnia but now I wake up a lot at night. Over-the-counter melatonin does nothing for me. Is the melatonin used in replacement therapy somehow different?

The ADHD-Insomnia Connection

Got ADHD? Chances are you’ve got insomnia symptoms, too. About 92 percent of the subjects in a recent study of adults with ADHD reported going to bed late because they were “not tired” or “too keyed up to sleep.”

The sleep problems of adults with ADHD may be due to delayed (and possibly less stable) circadian rhythms. If you’ve got ADHD-related insomnia, treatments aimed at advancing circadian phase may help.
