Understanding Sleep Deprivation: Why I Avoid Sleep

Sleep is an essential pillar of health, alongside good nutrition and exercise. However, many people struggle with bedtime procrastination, or revenge bedtime procrastination, where they delay sleep beyond their intended bedtime. This phenomenon is driven by various factors, such as busy schedules, stress, and the desire for personal time. While occasional bedtime procrastination is normal, consistently sacrificing sleep can lead to sleep deprivation, negatively impacting both physical and mental health. To combat this issue, it is crucial to address the underlying causes and develop healthy sleep habits and a relaxing bedtime routine.

Revenge bedtime procrastination: staying awake to reclaim personal time lost during the day

Revenge bedtime procrastination is a phenomenon where people put off sleep in favour of "me time" activities. The term was popularised in China, but the phenomenon is likely widespread, with overworked individuals all over the world staying awake to claim some personal time. It is especially common among people with busy, high-stress lives and those with poor time-management skills.

Reasons for revenge bedtime procrastination

People may engage in revenge bedtime procrastination due to various reasons, including:

• Busy schedules and daily responsibilities that prevent the enjoyment of leisure time earlier in the day.
• High-stress jobs or lifestyles that leave little time for personal activities.
• Poor time management skills that result in a lack of personal time.
• A desire to reclaim freedom and control over one's time, especially after a long and demanding day.

Impact of revenge bedtime procrastination

Engaging in revenge bedtime procrastination can have several consequences, including:

• Exhaustion and fatigue: Staying up late consistently can lead to fatigue and a lack of energy during the day.
• Poor productivity: Lack of sufficient sleep can impact focus, concentration, and overall productivity.
• Health ramifications: Inadequate sleep has been linked to various health issues, including impaired cognitive function, a weakened immune system, anxiety, mood disorders, and increased mortality.
• Shame: Individuals may feel guilty or ashamed about their sleep habits, especially if they know that staying up late is unhealthy.

Strategies to address revenge bedtime procrastination

• Reclaim daytime hours: Prioritise satisfying and tiring activities during the day and stick to a schedule. This will make staying up late less tempting.
• Practice good sleep hygiene: Establish a bedtime routine and maintain consistent sleep and wake-up times, even on weekends. Avoid screens at least an hour before bed, as the blue light from electronic devices can interfere with sleep.
• Set your circadian clock: Incorporate early morning sunlight and sunsets into your daily routine to regulate your body's natural sleep-wake cycles.
• Prioritise self-care: Learn to put yourself first consistently and set boundaries to ensure you get the personal time you need during the day.
• Address the root cause: Revenge bedtime procrastination is often a symptom of underlying issues, such as high stress levels, poor time management, or a lack of freedom and control over one's daily life. Addressing these root causes can help reduce the urge to stay up late.

Seeking professional help

While occasional revenge bedtime procrastination is normal, consistent sleep deprivation can negatively impact your health. If you feel that your sleep habits are affecting your daily life, consider seeking professional help. A therapist or doctor can help you examine the source of your sleep issues and provide guidance on improving your sleep habits and overall well-being.

Sleep disorders: conditions like insomnia, restless leg syndrome, or sleep apnea

Sleep disorders are a common issue that can significantly impact your health and well-being. There are several types of sleep disorders, including insomnia, restless leg syndrome, and sleep apnea.

Insomnia is a sleep disorder characterised by difficulty falling or staying asleep. It can be acute, lasting from one night to a few weeks, or chronic, occurring at least three nights a week for three months or more. Insomnia may be primary, meaning it is not linked to any other health condition, or secondary, where it is caused by an underlying health issue, medication, or substance use. Stress, environmental factors, genetic factors, mental health issues, and certain medications can all contribute to insomnia.

Restless legs syndrome (RLS), or Willis-Ekbom Disease, is a neurological disorder causing unpleasant sensations in the legs and an irresistible urge to move them. The symptoms are typically triggered by resting or attempting to sleep and can severely disrupt sleep patterns. RLS affects up to 10% of the US population and is more common in females. While there is no cure, treatments are available to manage symptoms, including medication and lifestyle changes.

Sleep apnea is a sleep disorder characterised by pauses in breathing or shallow breaths during sleep. These breathing interruptions can last from a few seconds to minutes and can occur 30 times or more per hour. Sleep apnea can lead to frequent awakenings and affect the quality of sleep. It is a serious condition that can increase the risk of various health problems, including high blood pressure, heart disease, and stroke.

If you are experiencing sleep difficulties, it is important to consult a healthcare professional for proper diagnosis and treatment. They may recommend lifestyle changes, behavioural therapy, or medications to improve your sleep quality and duration.

Circadian rhythm misalignment: when your internal clock doesn't match your environment

Circadian rhythm misalignment occurs when an individual's sleep-wake cycle is out of sync with their internal circadian clock and the external environment. This can be caused by shift work, jet lag, or social jet lag, where an individual's sleep schedule is misaligned with their social schedule.

Circadian rhythm misalignment can have negative health consequences, including an increased risk of cardiovascular disease, diabetes, obesity, cancer, and psychiatric disorders such as depression, bipolar disorder, and attention-deficit hyperactivity disorder (ADHD).

Circadian rhythm misalignment can lead to sleep disturbances, daytime sleepiness, changes in feeding patterns, metabolic function, and mood. It can also disrupt the timing of central and peripheral clocks, such as the timing of central vs. peripheral clocks, which can have downstream effects on health.

Treatments for circadian rhythm misalignment include bright light therapy and melatonin supplementation, which can help to realign the circadian rhythm with the external environment.

Stress and anxiety: elevated cortisol levels can disrupt sleep

Stress and anxiety can have a significant impact on sleep patterns and quality. Cortisol, often referred to as the "stress hormone," plays a crucial role in the body's response to stress and regulation of sleep-wake cycles. When faced with stressful situations, the body releases cortisol, which can be beneficial in short bursts, preparing us for a "fight-or-flight" response. However, chronically elevated cortisol levels due to prolonged stress or anxiety can disrupt sleep and contribute to a vicious cycle.

Elevated cortisol levels at night can make it difficult to fall asleep and lead to insomnia and other sleep disturbances. This disruption can be attributed to the alerting effects of cortisol, which increases heart rate and prepares the body for potential threats. As a result, individuals may experience difficulty falling asleep, frequent awakenings during the night, and reduced sleep duration.

Additionally, stress and anxiety can affect sleep indirectly through their impact on mental health. Research has linked high cortisol levels with various mental health conditions, including anxiety and depression. These conditions can further exacerbate sleep problems, creating a cycle of poor sleep and elevated cortisol.

To break this cycle, it is essential to address the underlying stress and anxiety. This may involve stress management techniques, such as mindfulness or deep breathing exercises, improving sleep hygiene, maintaining a consistent sleep schedule, and creating a relaxing bedtime routine. Additionally, seeking professional help or therapy can be beneficial in managing stress, anxiety, and their impact on sleep.

By reducing stress and regulating cortisol levels, individuals can improve their sleep quality and overall well-being. It is important to note that everyone's experience with stress, anxiety, and sleep is unique, and a personalized approach is often necessary to address these interconnected issues effectively.

Poor sleep hygiene: e.g. screen time, caffeine, and a sedentary lifestyle

Poor sleep hygiene can be a major factor in a person's reluctance to sleep. This can include excessive screen time, high caffeine consumption, and a sedentary lifestyle.

Excessive screen time before bed, particularly on smartphones, has been linked to bedtime procrastination. Research has shown that procrastinators spend an average of 80 minutes on their devices before bed, compared to 18 minutes for non-procrastinators. This can have a significant impact on sleep quality and duration, leading to negative health outcomes such as cardiovascular issues, cognitive problems, and depression.

Caffeine consumption, especially in the afternoon and early evening, can also disrupt sleep. Caffeine taken even 6 hours before bedtime can reduce total sleep time by over an hour. This can have detrimental effects on daytime functioning if experienced over multiple nights. It is recommended to refrain from substantial caffeine use for at least 6 hours before bedtime.

A sedentary lifestyle can also contribute to sleep problems. Daytime activity and exercise are important for maintaining strong circadian rhythms and achieving good quality sleep. Lack of routine and physical activity during the day can increase the risk of developing mental or physical disorders, which can, in turn, impact sleep. Additionally, long periods of sitting can cause stiffness in the neck and back, affecting sleep quality and contributing to a poor sleep posture.

To improve sleep hygiene, it is important to establish a healthy routine, including regular exercise, a healthy diet, and moderate screen time. These behaviors contribute to good sleep hygiene, which helps to maintain strong circadian rhythms and promotes better sleep.
