Menopause and insomnia: Could a low-GI diet help?

Sleep disturbances such as insomnia are extremely common, especially in women after menopause. According to data from the National Institutes of Health, sleep disturbance varies from 16% to 42% before menopause, from 39% to 47% during perimenopause, and from 35% to 60% after menopause.

Insomnia is a serious medical problem defined by frequent difficulty falling or staying asleep that impacts a person’s life in a negative way. Hormone changes around menopause can lead to sleep problems for many reasons, including changing sleep requirements, increased irritability, and hot flashes.

What menopausal women eat could have an impact on their risk of developing insomnia

Researchers recently looked at detailed dietary data from over 50,000 postmenopausal women (average age 63) enrolled in the Women’s Health Initiative study between 1994 and 2001. Carbohydrate intake was measured in several ways: glycemic index (GI) and glycemic load (GL), measures of added sugars, starch, total carbohydrate, and dietary fiber, and specific carbohydrate-containing foods such as whole grains, processed or refined grains, whole fruits, vegetables, and dairy products. They then looked at each participant’s risk of developing insomnia after three years of follow-up.

They found that the risk of developing insomnia was greater in women with a higher-GI diet, as well as in women who included more added sugars in their diet. Added sugars included white and brown sugar, syrups, honey, and molasses. The risk of developing insomnia was lower in women who ate more whole fruits and vegetables.

The researchers accounted for and adjusted for many potentially confounding factors, including demographic (education, income, marital status), behavioral (smoking, alcohol, caffeine intake, physical activity), psychosocial (stress, social connection), and medical factors (body mass index, various medical diagnoses, hormone therapy, snoring).

What is the glycemic index of food, and how could this affect sleep?

The glycemic index (GI) is a ranking of foods on a scale from 0 to 100 according to how much they raise blood sugar levels after eating them. I’ve written previously about planning meals with knowledge of the GI and the glycemic load of foods. High-GI foods are those that are rapidly digested, absorbed, and metabolized, and cause spikes in blood sugar and insulin levels. Some examples of high-GI foods include anything made with processed grains (bread, pasta, baked goods, white rice) and anything containing added sugars (sugary beverages, sweets).

Low-GI foods don’t cause your blood sugar and insulin levels to spike, and include plant foods such as most fruits and vegetables, legumes and beans, nuts, seeds, and whole grains. Even plant foods that have a high GI — such as bananas and watermelon — are not likely “bad” for you when eaten in moderation.

Researchers hypothesize that high-GI foods cause insomnia because of the rapid spike and then crash of blood sugar levels. Essentially, what goes up must come down, and after blood sugar and insulin levels peak, they tend to drop, which can cause a lot of symptoms, including awakening from sleep. The researchers of this new study cite multiple studies supporting this theory.

Nutrition is critical for so many aspects of our health, including sleep

Endless research connects the quality of our diet with our risk for heart disease, strokes, dementia, depression, and cancer. This new research notes that diet can also impact our risk for certain sleep problems. It’s not just about eating the obviously healthy foods, but also about avoiding the obviously unhealthy foods.

So how can you apply these findings?

In addition to practicing good sleep habits, here are some additional ways postmenopausal women can incorporate what we have learned from this study to sleep better (and be all-around healthier):

• Go for low-GI foods as much as possible. This means aiming to eat fruits and vegetables, beans and legumes, nuts and seeds, whole grains, and lean protein instead of anything made of processed grains or with added sugars. Think plain yogurt with berries and nuts instead of cereal or bagels for breakfast; a big plate of roasted vegetables and grilled salmon instead of pasta and meatballs for dinner.
• Never eat large meals close to bedtime. As a general rule, a large meal should be eaten at least three to four hours before lying down, maybe more. You do not want to go to bed with lots of food in your intestines!
• If you have to have a little something closer to bedtime, avoid sugars and processed grains. A sliced apple with a little almond butter; some blueberries and nut milk; or maybe hummus and carrots. Those are all well-balanced, plant-based snacks.

Sleep Problems and Menopause: What Can I Do?

Español

The years of the menopausal transition are often a time when there are other changes in a woman’s life. You may be caring for aging parents, supporting children as they move into adulthood, taking on more responsibilities at work, and reflecting on your own life journey. Add symptoms of menopause on top of all this, and you may find yourself having trouble sleeping at night.

Hot flashes, especially night sweats, and changes in mood — depression in particular — can contribute to poor sleep. Managing these issues may help to manage sleep symptoms as well.

Some women who have trouble sleeping may use over-the-counter sleep aids such as melatonin. Others use prescription medications to help them sleep, which may help when used for a short time. But these are not a cure for sleep disturbances, such as insomnia, and should not be used long term.

Not getting enough sleep can affect all areas of life. Lack of sleep can make you feel irritable or depressed, might cause you to be more forgetful than normal, and could lead to more falls or accidents. And research now suggests that waking from sleep itself may trigger hot flashes, rather than the other way around.

Developing healthy habits at bedtime can help you get a good night’s sleep.

Getting a good night’s sleep during the menopausal transition

To improve your sleep through the menopausal transition and beyond:

• Follow a regular sleep schedule. Go to sleep and get up at the same time each day.
• Avoid napping in the late afternoon or evening if you can. It may keep you awake at night.
• Develop a bedtime routine. Some people read a book, listen to soothing music, or soak in a warm bath.
• Try not to watch television or use your computer or mobile device in the bedroom. The light from these devices may make it difficult for you to fall asleep.
• Keep your bedroom at a comfortable temperature, not too hot or too cold, and as quiet as possible.
• Exercise at regular times each day but not close to bedtime.
• Avoid eating large meals close to bedtime.
• Stay away from caffeine (found in many coffees, teas, and chocolate) late in the day.
• Remember, alcohol won’t help you sleep. Even small amounts make it harder to stay asleep.

Talk to your doctor if you are having trouble sleeping. If these changes to your bedtime routine don’t help as much as you’d like, you may want to consider cognitive behavioral therapy for insomnia. This problem-solving approach to therapy has been shown to help improve sleep in women with menopausal symptoms. Cognitive behavioral therapy can be found through a class or in one-on-one sessions. Be sure that your therapy is guided by a trained professional with experience working with women during their menopausal transition. Your doctor may be able to recommend a therapist in your area.

Hot flashes and insomnia during menopause: what to do

With the onset of menopause, the amount and quality of sleep changes for the worse. The gradual fading of ovarian function and its complete cessation leads to insomnia, since its development is directly dependent on melatonin and estrogen.

Melatonin is the main regulator of circadian rhythms. With a decrease in this substance, not only sleep worsens, but other symptoms of menopause are exacerbated: hot flashes, irritability, apathy.

Estrogens – female sex hormones – affect in a complex:

• prolong REM sleep, make it easier to fall asleep;
• reduce the number of spontaneous awakenings per night;
• increase sleep duration.

The decrease in hormones during menopause is reflected in sleep.

What to do with hot flashes and insomnia during menopause? Experts often suggest starting artificial hormones. They replace their own estrogens and thereby eliminate or reduce the symptoms of menopause. Such drugs should not be taken without analysis and agreement with the doctor, subsequent health monitoring. Hormone therapy is contraindicated in a number of chronic diseases, which, unfortunately, are not rare in women over 45-50 years old.

An alternative to drugs for insomnia with menopause are complexes with phytoestrogens. These are active ingredients of plant origin, sensitive to estrogen, reduce the severity of menopause symptoms. Phytoestrogens do not have side effects and contraindications characteristic of synthetic hormones, they have a cumulative effect, they act gently, they can be taken for a long time, and dependence is not formed.

The non-hormonal complex Lady’s formula® Menopause Day-Night™ with anti-age effect is an excellent alternative to hormones, it has the recommendations of the Russian Society of Obstetricians and Gynecologists to eliminate the symptoms of menopause and insomnia.
