Wie Sie Ihre Schlafprobleme in den Wechseljahren lindern können

Research conducted on behalf of the British Menopause Society (BMS) revealed that around 4 in 10 women surveyed had unexpected Wechseljahresbeschwerden that were worse or much worse than expected. One of these was sleep disturbance. More than 7 in 10 women experienced night sweats that disrupted their sleep.

Other studies suggest that around 6 in 10 women will have Schlaflosigkeit or other sleep problems at menopause. A multi-ethnic study in the USA found that difficulty staying asleep was the most common problem, with sleep maintenance and early morning wakening worsening significantly through late perimenopause.

The health impact of poor sleep

"Quality of sleep declines for everyone as they age," explains Dr Heather Currie, a specialist gynaecologist, and founder of Menopause Matters. "But significantly so for many women as they approach menopause. And it doesn't just impact upon mood, energy and brain function in the short term."

Dr Michael Savvas, a consultant gynaecologist with a special interest in menopause and sleep disturbance, agrees.

"It's important to recognise that disturbed sleep is a major symptom of the menopause that often goes unrecognised," he says. "Poor sleep has long-term effects, including Herz-Kreislauf-Erkrankungen, Diabetes, Demenz und Fettleibigkeit, reduced Immunsystem, and even Krebs. So, it is crucial to take steps to improve things if you're not getting around seven hours of good-quality sleep every night."

"Studies have shown that the change in hormone levels (oestrogen and progesterone) has a direct effect on the sleep cycle beyond hot flushes and night sweats," says Currie. "Also, melatonin levels lower as we age, and this impairs the circadian system that regulates sleep."

Hot flushes and night sweats

Hot flushes and night sweats (vasomotor symptoms) are caused by changing hormone levels affecting the body's temperature control. "These symptoms are often at their worst during perimenopause," says Savvas, "though for some women they may last for up to ten years or more."

Insomnia and mood disorders

Mood changes are common in menopause and include Depressionen, Angstzustände, and irritability.

"Anxiety can make it difficult to get to sleep and depression can be a factor in non-restorative sleep and early morning waking," says Currie. "Though it has been proposed that menopausal sleep disturbance may actually be the underlying cause of anxiety and depression."

"There is a greater risk of developing mood changes around the time of the menopause if there is a history of postnatale Depression und pre-menstrual syndrome," adds Savvas.

Genitourinary syndromes of menopause (GSM)

A 2015 Studie revealed that 45%-63% of menopausal women had bladder and vaginal symptoms including needing to pee during the night (nocturia), soreness and irritation, and painful sex (Dyspareunie). The decline in oestrogen leads to thinning, drying, and inflammation (atrophic changes) of the delicate tissues in the bladder and vagina, which can cause sleep disturbance.

Flare-ups of vaginal Soor, bakterieller Vaginose, bladder infections, overactive bladder syndrome, Vulvodynie, and Lichen sclerosus are also common in menopause.

Muskuloskelettale Probleme

Many women having Gelenkschmerzen at menopause, and aching, twitching muscles. Research found that chronic pain syndromes such as Fibromyalgie may worsen at menopause, and women with Restless-Legs-Syndrom (RLS) often find the condition is worsened.

"One study of RLS patients found 69% of postmenopausal women perceived their symptoms as worse than before menopause," says Currie. "However, it is not clear whether restless leg syndrome contributes to sleep disturbance, or if women who are not sleeping well are more aware of the problem."

Breathing issues

Studies show that sleep-disordered breathing and obstruktive Schlafapnoe are more common after menopause. These conditions may be associated with weight gain, and lowered levels of progesterone as this hormone influences the respiratory system.

"Sleep apnoea is not just about loud snoring and gasping," observes Currie. "In women it can also manifest as headaches, insomnia, depression or anxiety, and daytime fatigue. Studies have shown that night sweats and hot flushes may be linked to increased risk of sleep apnoea, and it appears to be more common in women who have had a surgical menopause compared to natural menopause."

Simple Schlafhygiene tips such as cutting out caffeine from the afternoon onwards, and avoiding heavy meals, alcohol, nicotine, and screen-time later in the evening can help you rest better.

Hormonersatztherapie (HRT)

Topical Hormonersatztherapie (HRT) in the form of oestrogen creams and intra-vaginal pessaries can help alleviate vulval symptoms, and vaginal and urethral atrophy. But beware of products that contain mineral oil or other additives that can irritate sensitive tissues.

Systemic HRT can improve sleep quality, making it easier to get off to sleep, with less night-time waking. it has also been shown to improve chronic pain, mood and genitourinary symptoms, and ease hot flushes and night sweats.

Savvas is a member of the BMS medical advisory group and co-authored their guidelines on the use of HRT.

"HRT is the most effective way of alleviating menopausal symptoms, including issues that disturb sleep," he advises. "It is safe for most women to use and also protects against Osteoporose und Herzerkrankungen. Taking oestrogen transdermally - by a patch, gel, or spray - rather than by tablet reduces the tiny cancer risk even further and there is no risk of Thrombose. There is no time limit for how long you can stay on HRT though you should discuss this with your doctor."

The primary aim of HRT is to treat symptoms caused by oestrogen deficiency. However, for sleep disturbance, the addition of progesterone may have an added benefit. Utrogestan, natural progesterone, taken by mouth at night can increase drowsiness and help induce sleep - though the effect depends on dosage, and how it is metabolised varies from person to person. Progesterone is also associated with increased non-REM 3 sleep which is crucial for well-being.

Standard treatments for sleep issues

"Studies have shown that kognitive Verhaltenstherapie (CBT) reduces menopausal symptoms including low mood, anxiety, and sleep disturbance," says Currie. "Sleep hygiene and lifestyle changes are also useful. HRT is recommended to be used first-line for menopausal symptoms, but for women who are unable to take HRT, other medicines such as low-dose antidepressants, and Gabapentin and clonidine may be helpful particularly for night sweats."

Savvas adds that women in perimenopause who are having sleep problems are often wrongly treated with sleeping pills for insomnia, when in fact it is declining hormone levels that are the cause.

"Women in their 40s who are still having periods may start getting sleep issues, mood changes, and anxiety which are common symptoms in perimenopause," he explains. "If this is the case for you, make sure their GP considers perimenopause as a possibility. Sleeping pills may be helpful in the short term, but there are numerous side-effects with long-term use, including dizziness, memory problems and even increased risk of dementia."

Supplements and complementary therapies

There are various alternatives to HRT to ease the symptoms of menopause.

Interest has been shown in the use of melatonin for sleep disturbance, as the 'sleep hormone' is influenced by the decline in oestrogen and progesterone at menopause. However, there is uncertainty around the appropriate dose and possible interactions with medicines including Antidepressiva, Antikoagulantien, and medicines for diabetes.

"While it's true that the body produces less melatonin with age," says Savvas, "the evidence that melatonin actually helps with sleep is poor. It can help with jetlag where the circadian rhythm is out of sync, but there's little evidence of benefit in supplement form for long-term sleep issues or for women at menopause."

Yoga, acupuncture, massage, and meditation have all been shown to have beneficial effects on wellbeing and may help with relaxation and sleep. There is limited evidence to show that supplements such as magnolia bark, L-theanine, magnesium, 5-HTP, and valerian can help improve sleep - and black cohosh and red clover are thought to reduce night sweats. Phytoestrogens from plants including soya, tofu, chickpeas, and nuts also act like a weaker form of oestrogen in the body.

However, more scientific evidence for effectiveness is needed for supplements, phytoestrogens, and complementary therapies. Not all supplements contain pure ingredients or high enough levels to have a therapeutic effect, and they may induce side effects or have contra-indications with other medicines.
