Melatonin content may differ from amount listed on label

How Much Melatonin Is Really in That Supplement?

Supplementary melatonin is the fourth most popular natural product used by adults in the United States and the second most popular given to children.

But supplements like melatonin are not subject to the same quality controls as prescription medications. A new study of melatonin sold over-the-counter shows that information on the label often does not reflect the content of the product.

Insomnia with short sleep increases susceptibility to overweight

Sleep and Body Weight: A Close Relationship

“If you weigh too much, maybe you should try sleeping more.”

This commentary in the journal Sleep caught my eye. Flip as it sounds to a person who would sleep more if she could, it points to a relationship between sleep and body weight that should be widely publicized.

Sleep can also affect your ability to keep weight off. As for the relationship between insomnia and body weight, the latest news is surprising. Read on for details:

Paradoxical insomnia may respond to treatment with CBT & therapies lowering arousal

Paradoxical Insomnia: A Second Look at Treatments

Paradoxical insomnia: a diagnosis given to people whose sleep studies show they sleep a normal amount but who perceive they sleep much, much less. When I wrote about it in 2015, the word was that cognitive behavioral therapy (CBT)—the gold standard in treatments for insomnia—might not be an effective treatment for it.

But a brief testimonial that recently appeared in American Family Physician argues otherwise. Here’s an update on this puzzling sleep disorder.

Insomnia can be relieved by focusing on stress reduction and self-care

Tips for Stressed-Out Caregivers Seeking Better Sleep

Occasionally I get emails from people with take-charge, type A personalities wondering what to do about insomnia. Full of self-reliance, they’ve often scoured the internet for remedies—and tried every one—or amassed a mountain of books about sleep—and read them all—to little avail. Can I suggest anything that might help?

Coffee: The Sleepless, Too, Can Enjoy the Benefits

I love coffee and I’m always glad to hear coffee is beneficial to my health. Two new studies—one of humans and the other of mice—add to this growing body of knowledge.

Yet coffee contains caffeine, and people with insomnia are often advised to cut down on caffeine because it interferes with sleep. Is there a middle course the sleepless can steer to avoid the harms and reap the benefits?

Proteins linked to Alzheimer's a function of insufficient deep sleep

Alzheimer’s Disease: Are You, Poor Sleeper, at Risk?

I talk quite a bit about dementia and Alzheimer’s disease with family and friends. Our parents are drifting into cognitive impairment, asking the same questions again and again and struggling to find words to express themselves, and we wonder if we’re destined for the same fate.

The concern may be justified in middle-aged adults with chronically poor sleep, according to new research on sleep and two proteins involved in Alzheimer’s disease. Here’s more about the study and its relevance to people with insomnia and other sleep disorders.

Causes of insomnia are closer to being figured out

7 New Insomnia Genes: What’s in It for Us

A flurry of articles recently announced the discovery of seven new risk genes for insomnia. In an era when new genes are being identified for everything from infertility to schizophrenia, you might regard this discovery as simply the soup du jour.

Not me. Growing up when trouble sleeping was attributed to psychological factors, coffee, and alcohol, I was elated by this news. We stand to gain so much from knowing the genetic underpinnings of insomnia.

Have you had insomnia all your life? Have your parents said you were a poor sleeper even as a baby?

Trouble sleeping that starts early in life is called idiopathic insomnia. If insomnia is still the black box of sleep disorders, then idiopathic insomnia is the little black box inside the black box.

Here’s what is known about the disorder and options for management.
