Daytime Sleep: Easier And Here's Why

Many people find it easier to sleep during the day than at night. This phenomenon could be attributed to various factors, including individual differences in circadian rhythms, stress, and anxiety levels, as well as environmental factors such as light and noise. For some, daytime sleep may be a result of working night shifts or a sign of underlying health conditions like insomnia, depression, or Delayed Sleep Phase Syndrome (DSPS). Establishing a consistent sleep schedule, creating a relaxing sleep environment, and practising good sleep hygiene can help improve nighttime sleep.

A person's sleep/wake cycle may be delayed with respect to the external day/night cycle

There are several factors that can contribute to this condition:

• Stress and Anxiety: The pressure to fall asleep at night and the associated stress and anxiety can make it more challenging to fall asleep. During the day, there is less perceived pressure to sleep, allowing individuals to relax and fall asleep more easily.
• Trauma: For individuals who have experienced trauma, the daytime, especially with the presence of sunlight, may feel safer and more relaxing, making it easier to fall asleep.
• Circadian Rhythm Mismatch: For those who work night shifts or have irregular work schedules, their internal circadian rhythm may not align with the external day/night cycle. This mismatch can lead to insomnia and other sleep disorders.
• Sleep Deprivation: Sleep deprivation, whether due to external factors or underlying sleep disorders, can disrupt the body's natural sleep/wake cycle. As a result, individuals may find themselves sleeping during the day to compensate for lost sleep at night, creating a cycle that further delays their sleep/wake cycle.
• Environmental Factors: Factors such as exposure to sunlight, noise, temperature, and electronic device usage can impact sleep quality. Adjusting the sleep environment to minimise these distractions can help improve sleep during the night.
• Lifestyle Choices: Consuming caffeine, alcohol, or certain medications close to bedtime can disrupt sleep patterns. Engaging in relaxing activities, such as meditation or a warm bath, can aid in preparing the body and mind for sleep.

It is important to note that if individuals suspect they may have a sleep disorder or experience persistent difficulties with their sleep/wake cycle, they should consult a healthcare professional or a sleep specialist for personalised advice and treatment options.

During the day, there is no pressure to hurry up and get some sleep

This can be contrasted with nighttime sleep, where there is a sense of urgency to fall asleep as soon as possible. This pressure can sometimes lead to performance anxiety, making it harder to fall asleep.

Additionally, during the day, people are often occupied with work or other activities, which can help take their minds off the need to sleep. At night, the absence of such distractions can make it more difficult to fall asleep, especially if one is already sleep-deprived.

Furthermore, the body's natural circadian rhythm is aligned with the day-night cycle, making it easier to fall asleep at night and wake up in the morning. Attempting to sleep during the day goes against this natural rhythm, which can make it challenging for some people.

However, for those who work night shifts or have other commitments that require daytime sleep, establishing a consistent daytime sleep schedule is crucial. This may involve creating a relaxing sleep environment by blocking out sunlight, reducing noise, and maintaining a comfortable temperature. It is also essential to minimize distractions, such as turning off phones or electronic devices, to ensure uninterrupted sleep.

People may feel safer and more relaxed during the day

Additionally, some people may find daytime sleeping more manageable due to the absence of social expectations or pressure to fall asleep. During the day, there is less emphasis on the need to "hurry up and get some sleep", allowing individuals to approach sleep with a calmer mindset. This can be particularly beneficial for those who struggle with insomnia or a restless mind at night.

Furthermore, the daytime can provide a sense of comfort and security for those who find solace in the presence of others. Being around people or simply hearing them nearby can help drown out intrusive thoughts and worries, making it easier to fall asleep. This sense of connection and companionship can promote relaxation and improve sleep quality.

Finally, the daytime may offer a sense of flexibility and freedom regarding sleep schedules. Without the pressure of adhering to a strict bedtime routine, individuals may feel more in control of their sleep patterns. This can reduce the performance anxiety associated with falling asleep at night, making it easier to drift off during the day.

Daytime naps can be helpful but may also signal chronic sleep deprivation

Napping during the day can be beneficial in multiple ways. In many cultures, napping in the afternoon is a common practice and is considered a part of daily life. In the US, about a third of adults take a midday catnap, as per the National Sleep Foundation. These short daytime sleeps can help you catch up on a late night, make you feel less cranky, or ensure you're well-rested for a job that falls outside traditional daytime work hours. They can even keep you safe on the road by protecting you from drowsy-driving accidents.

However, the need to nap during the day might also indicate chronic sleep deprivation. Some studies have found that adults who take long naps during the day are more likely to have conditions such as diabetes, heart disease, and depression. The urge to sleep during the day could be a sign that they are not getting enough sleep at night, which is associated with a higher risk of developing those chronic conditions. Daytime drowsiness may also be a sign of low-quality sleep, possibly indicating a sleep disorder.

Additionally, napping can create a vicious cycle. You sleep during the day to make up for lost sleep at night, but then you have a harder time falling asleep at night because you napped. Limiting naps might be a strategy to improve overall nighttime sleep.

If you plan to take a nap during the day, it is recommended to time it right by choosing the early afternoon when your body experiences a natural circadian dip. Keeping it short, around 20 minutes, may be best to avoid grogginess and trouble falling asleep later.

If you nap regularly, it is important to assess why you may be sleepy enough to fall asleep during the day. Track your sleep to see how much shut-eye you are getting at night. If you aren't getting enough, try to improve your sleep habits. If you are already getting at least seven or more hours of sleep at night and are still tired during the day, discuss this with your doctor.

Sleep disorders, such as insomnia, may be a reason why it is easier to sleep during the day

Hypersomnia is a condition where individuals experience extreme daytime sleepiness despite getting sufficient or more than adequate nighttime sleep. It affects an individual's ability to function socially and at work and increases the risk of accidents. Hypersomnia can be caused by various factors, including sleep disorders such as insomnia, medical conditions, medications, mental states, and environmental factors.

For individuals with insomnia, the pressure to fall asleep during the day may be less intense compared to the nighttime routine. The expectation to sleep at night, along with the mental inventory of the day's experiences and planning for the next day, can contribute to a more challenging sleep onset. During the day, the absence of this pressure and mental activity can make it easier to fall asleep.

Additionally, the natural light cycles and the body's circadian rhythm play a significant role in sleep patterns. Working night shifts or having a circadian rhythm disorder can disrupt the alignment between an individual's internal body clock and the natural light-dark cycles, making it easier to sleep during the day instead of at night.

If you suspect that you may have a sleep disorder, it is advisable to consult a healthcare professional or a sleep specialist for an accurate diagnosis and appropriate treatment. They can help identify any underlying conditions and provide guidance on improving your sleep quality.
