Sleep Deprivation: Navigating The Week's Restlessness

Sleep is a necessity, but for many, it doesn't come easy. Insomnia is a common sleep disorder that affects nearly 30% of adults in the United States. It can be chronic, occurring at least three times a week for at least three months, or temporary, lasting less than three months. Those with insomnia may wake up frequently during the night, be unable to fall back asleep, and experience daytime fatigue, mood changes, and problems with concentration and memory.

There are many factors that can contribute to insomnia, including lifestyle choices, sleep habits, stress, and medical conditions. For example, consuming alcohol or caffeine before bed, napping late in the day, sharing a bed with a partner or pet, and having an irregular sleep schedule can all impact sleep quality. Additionally, certain medications, mental health disorders, and physical illnesses can also disrupt sleep.

To improve sleep quality, it is recommended to limit alcohol and caffeine intake, especially close to bedtime, establish a relaxing bedtime routine, maintain a consistent sleep schedule, and create a comfortable sleep environment.

Lifestyle factors: Alcohol, caffeine, and eating close to bedtime can disrupt sleep

Lifestyle factors such as alcohol, caffeine, and eating close to bedtime can disrupt sleep. Here are some ways in which these factors can impact your sleep:

Alcohol

While a glass of wine or two with dinner may make you feel relaxed or even sleepy, alcohol can interfere with your sleep. Although you may fall asleep quickly, alcohol can prevent you from falling into a deep sleep. It is recommended to avoid alcohol at least three hours before bedtime.

Caffeine

Caffeine, found in coffee, tea, soda, energy drinks, and chocolate, is a stimulant that can keep you awake. The effects of caffeine can last for hours after consumption, and it can stay in your system for up to six hours. To minimize its impact on your sleep, it is best to avoid caffeine eight hours before bedtime.

Eating Close to Bedtime

Eating a large meal close to bedtime can lead to discomfort and a disturbed night's sleep. Spicy foods can cause heartburn, and fatty foods can contribute to obesity, a risk factor for sleep apnea. It is advisable to eat dinner at least a couple of hours before bedtime and keep the meal light.

In addition to these lifestyle factors, it is also important to maintain a consistent sleep schedule, create a relaxing bedtime routine, and limit screen time before bed to improve your sleep quality.

Poor sleep habits: An irregular sleep schedule and napping can cause issues

An irregular sleep schedule can have a detrimental effect on your health. This includes sleeping too little during the week and then trying to make up for it on the weekend. This can negatively affect your body's metabolism, which controls how your body functions and uses energy. It can also put you at a higher risk of chronic diseases like diabetes.

The importance of a regular sleep schedule

Following a consistent sleep schedule trains your brain to recognise when it's time to sleep and when it's time to wake up. It's important to listen to your body and go to bed when you feel sleepy, but also to try to get 7-8 hours of sleep each night to meet your sleep needs.

The impact of napping

Napping can also interfere with your sleep quality. Naps lasting 2 hours or more are particularly problematic and may be a sign of a sleep disorder such as sleep apnea. If you have difficulty falling asleep at night, it's best to avoid taking prolonged naps. If you must nap, limit them to shorter periods of 15-20 minutes in the mid-afternoon and avoid sleeping in the late afternoon or evening.

Other factors affecting sleep quality

In addition to maintaining a regular sleep schedule and avoiding excessive napping, there are several other factors that can impact your sleep quality:

• Limit your exposure to electronic devices emitting bright blue light before bedtime, as this can trick your brain into delaying sleep.
• Make sure your bedroom is dark, quiet, and cool.
• Avoid consuming caffeine and alcohol close to bedtime, as these substances can disrupt your sleep.
• Get some sunlight in the morning to help wake you up and reset your circadian rhythm.
• Establish a relaxing bedtime routine with activities that calm you, such as taking a warm bath or listening to an audiobook.
• Exercise regularly, preferably in the morning, as it can help you sleep better. However, avoid high-energy aerobic exercise too close to bedtime, as it may make it difficult to fall asleep.

By addressing these factors and making some lifestyle adjustments, you can improve your sleep quality and overall health.

Work and travel: Shift work, long hours, and jet lag can affect sleep

Working late or irregular shifts can wreak havoc on your sleep schedule. Night shift workers often struggle to sleep during the day because their internal circadian alerting system is at its strongest during the daytime, making it difficult to fall asleep "on the wrong side of the clock". Similarly, staying awake at night can be challenging because the body's urge to sleep is at its peak. This can lead to chronic sleep deprivation, with night shift workers sleeping about one and a half hours less per night than daytime workers.

Shift work disorder, a chronic condition directly related to shift work, is characterised by insomnia when trying to sleep and excessive sleepiness when needing to be awake and alert. About half of all night shift workers experience this, and the resulting sleep deprivation can affect alertness, judgment, and performance, increasing the risk of accidents.

Measures to help shift workers include maintaining a consistent sleep schedule and creating a dark, comfortable, and quiet sleep environment. Workplace measures can also help, such as enhancing lighting to simulate daylight and the strategic use of caffeine.

Long work hours can also lead to poor sleep due to stress and anxiety about the upcoming work week. This can cause insomnia, especially on Sunday nights, as people start to dread the week ahead. Maintaining a regular sleep schedule, even on weekends, can help alleviate this.

Travelling for work can also disrupt sleep patterns due to jet lag, which occurs when your body's internal clock is out of sync with the current time zone. Symptoms include excessive daytime sleepiness, nighttime insomnia, headaches, loss of appetite, gastrointestinal problems, and irritability or mild depression. Jet lag is usually temporary, as the body's internal clock gradually adapts to the new time zone. To minimise its effects, it is recommended to avoid bright light during the late evening and night according to your internal clock and to seek light in the early morning.

Health conditions: Mental health issues, chronic pain, and sleep disorders can impact sleep

Mental Health Issues

Mental health and sleep are closely connected. Quality sleep is crucial for good mental health, but sleep issues can worsen mental health conditions, and mental health problems can lead to poor sleep. Sleep deprivation can increase the risk of mental health disorders, while also making it more difficult to cope with stress and regulate emotions. Research has shown that not getting enough sleep or poor-quality sleep can increase the risk of mental health disorders, including anxiety and depression, and even suicidal ideation.

Chronic Pain

Chronic pain is a prevalent problem, with over half of patients suffering from sleep disorders. Sleep problems can include difficulty falling asleep, sleep insufficiency, and low sleep quality, which can lead to a wide range of physical and mental problems. Sleep deprivation can increase subjective pain intensity and worsen peripheral/central pain sensitization. Sleep disorders are also one of the most common triggers of migraines. Patients with both chronic pain and sleep disturbances have greater pain severity, longer duration of pain, and are more likely to experience concurrent depression, anxiety, and suicidal ideation.

Sleep Disorders

Sleep disorders can be a cause and consequence of mental health problems. Obstructive sleep apnea (OSA), for example, is a disorder that involves pauses in breathing during sleep and a reduction in the body's oxygen levels, creating fragmented and disturbed sleep. OSA occurs more frequently in people with psychiatric conditions and may detract from their physical health and heighten their risk of serious mental distress.

Treatment Options

Cognitive behavioural therapy (CBT) is a commonly used treatment for both chronic pain and sleep disorders. It is recommended as a non-pharmacologic multimodal combination of treatments for coping with sleep problems and as a first-line therapy for insomnia. CBT aims to examine patterns of thinking and work to reformulate negative thoughts in new ways. In addition, certain medications and supplements, such as melatonin, pregabalin, and gabapentin, have been found to improve sleep quality and reduce pain.

Medication: Some prescriptions can cause insomnia or disrupt sleep

Prescription medications can sometimes be the cause of insomnia or poor sleep. If you are taking any of the following medications, it is worth considering if they might be the cause of your sleep issues.

Beta-blockers are used to treat high blood pressure, heart rhythm problems, and chest pain. They can lower your body's melatonin levels, causing you to wake up at night and experience nightmares. Beta-blockers include metoprolol, propranolol, atenolol, and labetalol, with the former two being more likely to cause sleep issues.

Selective Serotonin Reuptake Inhibitors (SSRIs) are a class of antidepressants that increase serotonin levels in the brain. While they can help treat anxiety and depression, they can also cause insomnia, nightmares, and sleep apnea. Common SSRIs include fluoxetine (Prozac), citalopram (Celexa), escitalopram (Lexapro), sertraline (Zoloft), paroxetine (Paxil), and fluvoxamine (Luvox).

Corticosteroids are used to lower inflammation and treat illnesses like asthma, allergies, rheumatoid arthritis, and lupus. They can cause insomnia, especially if taken later in the day. Examples of corticosteroids include cortisone, prednisone, methylprednisolone, and dexamethasone.

Cholesterol-lowering medications, or statins, can cause muscle pain that may make it difficult to sleep.

Cholinesterase inhibitors, used to treat Alzheimer's and dementia, can cause sleeplessness and nightmares. These include donepezil, galantamine, and rivastigmine.

Stimulants are often prescribed for ADHD and narcolepsy. They can cause insomnia, especially if taken later in the day.

Asthma medications can also disrupt sleep. Oral theophylline and inhaled rescue medicines can cause sleep problems and jitteriness, respectively.

If you suspect that any of these medications are affecting your sleep, it is important to consult your doctor before making any changes. They may be able to adjust your dosage or switch you to a different medication. Additionally, you can try taking your medication earlier in the day or improving your sleep habits by maintaining a regular sleep schedule, exercising, and reducing caffeine intake.
