Sleep is a complex process that is affected by multiple factors, including age, health, and lifestyle choices. As people age, they may experience changes in sleep patterns, such as a tendency to go to bed and wake up earlier, as well as a decrease in the quality and quantity of sleep. For individuals around the age of 46, sleep disturbances may be influenced by various factors, such as hormonal changes, increased stress, chronic health conditions, and the use of certain medications. Understanding the underlying causes of excessive sleepiness is crucial for improving sleep quality and overall well-being.

What You'll Learn
Hormonal changes, especially in perimenopausal women
During perimenopause, there is a decline in reproductive hormones such as estrogen and progesterone. This hormonal change can directly and indirectly affect sleep. One of the direct impacts is on melatonin production. Melatonin is a hormone that helps us feel sleepy, and its levels can significantly drop during perimenopause, making it harder to fall asleep. Additionally, the decrease in estrogen can lead to changes in the hypothalamus, the part of the brain that regulates body temperature. This can result in hot flashes, night sweats, and flushing, causing abrupt awakenings during sleep.
The hormonal changes during perimenopause can also have indirect effects on sleep. For instance, hormonal shifts can lead to weight gain, which has been linked to poorer sleep quality and longer sleep onset latency. Additionally, weight gain and the decline in reproductive hormones can contribute to sleep apnea, a common condition where breathing pauses during sleep, further disrupting sleep quality.
The symptoms of perimenopause can also include anxiety, moodiness, and brain fog, which may contribute to insomnia and sleep disturbances. Hormonal changes, along with life circumstances such as divorce or caring for ageing parents, can impact mental health and increase the risk of anxiety and depression, often accompanied by chronic insomnia.
To manage sleep issues during perimenopause, various treatments are available, including hormonal and non-hormonal medications. Hormone replacement therapy (HRT) can be effective in treating perimenopausal symptoms like hot flashes and night sweats by replacing reproductive hormones. However, it's important to consider the potential detrimental effects of hormone therapy. Non-hormonal medications, such as selective serotonin reuptake inhibitors (SSRIs), can also help with sleep symptoms. Lifestyle changes, such as reducing alcohol consumption, establishing a bedtime routine, and maintaining regular sleep hours, can also improve sleep quality during perimenopause.

Medication side effects
While sleeping pills can be effective in treating insomnia, they can also have side effects and are not recommended for long-term use. The side effects of sleeping pills vary by medication, and different people respond differently to them. The most common side effects include drowsiness, difficulty with movement, impaired focus the next day, and sleepwalking. Sleeping pills can also be habit-forming, and it is important to keep the dose and duration of use as low and short as possible to mitigate the risk of dependency. Other side effects may include confusion, memory issues, abnormal behaviour, muscle weakness, and impaired balance, which can increase the risk of falls and hip fractures, especially in older adults.
Additionally, certain prescription medications, over-the-counter drugs, and supplements can also cause insomnia or sleep disturbances as a side effect. For example, heart medications such as alpha-blockers and beta-blockers can interfere with sleep by reducing REM sleep and lowering melatonin levels, respectively. Cholesterol medications like statins can cause muscle pain that disrupts sleep. Alzheimer's drugs can induce sleeplessness and vivid dreams. Stimulants prescribed for ADHD and narcolepsy may also cause sleep problems. Oral asthma medications and certain inhaled rescue medicines can have similar effects. Corticosteroids, which are used to treat asthma and allergic reactions, can energize rather than induce sleep. Antidepressants, specifically selective serotonin reuptake inhibitors (SSRIs), can alter brain cell communication and impact sleep.
If you suspect that your medication is causing sleep disturbances, it is important to consult your doctor before making any changes. They may recommend adjusting the dosage, trying a different medication, or exploring natural sleep aids like melatonin.

Age-related health conditions
As people age, the way they sleep changes. Older adults tend to go to bed earlier and wake up earlier, and the amount of time spent in each type of sleep decreases. Sleep tends to become shorter and lighter, and older people may wake up more often during the night.
There are several age-related health conditions that can cause or contribute to excessive sleepiness or sleep disturbances. These include:
- Dementia: People with dementia, especially in the later stages, often experience extreme fatigue and spend a lot of time sleeping during the day and night. The damage to their brains makes it exhausting for them to perform simple tasks.
- Sleep disorders: Sleep disorders become more common with age. These include insomnia (trouble falling or staying asleep), sleep apnea (pauses in breathing during sleep), and movement disorders such as restless legs syndrome.
- Chronic illnesses: Conditions such as arthritis, chronic pain, and diabetes can make it difficult for older adults to fall asleep and stay asleep.
- Cardiovascular and pulmonary diseases: These conditions have been associated with sleep complaints in older adults.
- Mental health issues: Depression and anxiety can trigger insomnia, and untreated insomnia may lead to depression.
- Menopause and perimenopause: Hormonal changes during menopause and perimenopause can affect sleep in women in their 40s and 50s.
- Medications: Older adults are more likely to take medications that can interfere with sleep. Polypharmacy, or the use of multiple medications, is also more common in this age group.
- Obesity: Being overweight can lead to sleep apnea and other sleep-related issues.
If you are experiencing excessive sleepiness or sleep disturbances, it is important to consult a healthcare professional for personalized advice and treatment options.

Poor sleep habits
Consistent Sleep Schedule
Maintaining a consistent sleep schedule is crucial for a good night's rest. Aim to go to bed and wake up at the same time every day, even on weekends. This helps regulate your body's internal clock, known as the circadian rhythm, which governs your sleep-wake cycles. Disrupting this rhythm by staying up late or sleeping in on weekends can negatively affect your sleep quality.
Relaxing Bedtime Routine
Establish a relaxing bedtime routine to prepare your mind and body for sleep. Avoid intense exercise and exposure to bright lights or screens an hour before bed. Instead, engage in calming activities such as reading a book, listening to soothing music, or taking a warm bath. Reducing stimulation before bedtime helps signal to your body that it's time to wind down and prepare for sleep.
Comfortable Sleep Environment
Create a bedroom environment that is conducive to sleep. Keep your bedroom quiet, cool, and dark. Use light-blocking curtains if necessary to minimize external light. Ensure your bed is comfortable and inviting, and avoid working, eating, or engaging in stimulating activities in bed. By associating your bed with relaxation and sleep, you can improve your overall sleep quality.
Limit Caffeine, Nicotine, and Alcohol
Caffeine, nicotine, and alcohol can interfere with your sleep. Caffeine and nicotine are stimulants that can keep you awake, while alcohol can disrupt your sleep patterns as it wears off during the night. Avoid consuming caffeine and nicotine close to bedtime, and limit alcohol consumption to improve your sleep quality.
Regular Exercise
Engaging in regular exercise can promote better sleep. Aim for at least 30 minutes of daily exercise, but avoid strenuous workouts too close to bedtime as they can raise your body temperature, heart rate, and blood pressure, making it difficult to wind down. Finding the right balance between exercise and relaxation can improve your overall sleep habits.
Manage Stress and Anxiety
Stress and anxiety can significantly impact your sleep. If you're experiencing difficulty sleeping due to stress, consider relaxation techniques such as meditation or deep breathing exercises before bed. Additionally, cognitive behavioral therapy (CBT) can be beneficial in managing insomnia and improving your sleep habits in the long term.

Stress and anxiety
Sleep is highly sensitive to stress and anxiety. Experiencing stress and anxiety can cause poor sleep quality and insomnia. For example, lifestyle changes that come with ageing, such as retirement, loss of independence, and social isolation, can increase stress and anxiety, contributing to sleep issues.
People with mental health disorders may also develop nighttime anxiety or nocturnal panic attacks, which can cause them to wake up during the night. These disorders include anxiety disorders, panic disorder, post-traumatic stress disorder (PTSD), mood disorders, major depression, bipolar disorder, alcohol and substance use disorder, and schizophrenia.
Sleep anxiety is a feeling of stress or fear about going to sleep or staying asleep. It can be challenging to break the cycle of sleep anxiety, as spending too much time in bed worrying about falling asleep can cause you to associate your bed with stress. This can lead to a self-reinforcing cycle where the stress caused by worrying about sleep disrupts your sleep even further.
To break this cycle, it is important to address the underlying causes of your stress and anxiety. Lifestyle changes, such as regular exercise, stress reduction techniques, and a balanced diet, can help improve sleep quality. Additionally, relaxation techniques before bedtime, such as deep breathing, identifying and addressing sleep-related worries, and encouraging sleep while in bed, can be beneficial. Seeking help from a healthcare provider or a psychologist who specializes in sleep problems can also be helpful in managing sleep anxiety and improving sleep quality.
