There are many reasons why people sleep better with a partner. One of the main reasons is the feeling of safety and security that comes with sleeping next to someone. This can lead to a reduction in stress and anxiety, making it easier to fall asleep and contributing to a sounder sleep. Additionally, the physical touch and intimacy of sleeping with a partner can release oxytocin, also known as the cuddle chemical or love hormone, which promotes feelings of empathy, trust, relaxation, and reduced anxiety. Furthermore, research has shown that couples who sleep side-by-side experience increased and less disrupted rapid-eye movement (REM) sleep, which is associated with memory organization, emotion regulation, creative problem-solving, and improved social interactions. However, it is important to note that not all couples experience improved sleep when sharing a bed, as individual differences in sleep habits and preferences can come into play.

What You'll Learn
The release of oxytocin, dopamine, and serotonin
Oxytocin, often referred to as the "cuddle chemical" or the "love hormone", is a chemical compound produced in the brain that promotes feelings of empathy, trust, relaxation, and reduced anxiety. Physical touch and close contact with a partner stimulate the release of oxytocin, resulting in a sense of calmness and protection. This feeling of safety and security contributes to a more relaxed state, making it easier to fall asleep and enhancing the quality of sleep.
Additionally, the release of dopamine, often associated with pleasure and reward, is heightened when sharing a bed with a loved one. This increase in dopamine levels contributes to the feeling of happiness and pleasure associated with partnered sleep. Serotonin, known as the "happy chemical," is also released during shared sleep, further boosting mood and emotional well-being.
The combination of these chemical releases creates a positive feedback loop that reinforces the emotional and physical benefits of sleeping with a partner. The resulting sense of security, reduced anxiety, and improved mood contribute to a more relaxed state, making it easier to fall asleep and promoting deeper, more restorative sleep.
It is important to note that the benefits of oxytocin, dopamine, and serotonin release during partnered sleep may be more pronounced for individuals with secure attachment styles. According to attachment theory, romantic partners can serve as a secure base, providing feelings of safety and protection that buffer against daily stressors. This sense of security contributes to reduced psychological and physiological arousal, facilitating sleep onset and improving sleep quality.
While the release of these chemicals plays a role in better sleep with a partner, it is not the sole factor. Other aspects, such as relationship dynamics, attachment styles, and individual sleep habits, also come into play and can either enhance or hinder the sleep experience for couples.

Increased feelings of safety and security
Feeling safe and secure is a prerequisite for falling asleep. According to attachment theory, romantic partners serve as an important source of safety and security, especially during times of vulnerability.
When you sleep with someone you trust, your body releases oxytocin, the "cuddle chemical" or "love hormone". This hormone prompts feelings of empathy, trust, relaxation, and reduced anxiety. The release of oxytocin, along with the sense of security that comes from sleeping with a partner, can help you fall asleep faster and experience better rapid eye movement (REM) sleep.
Research has shown that couples who sleep side-by-side have increased and less disrupted REM sleep compared to when they sleep apart. This stage of sleep has been linked to memory organization, emotion regulation, creative problem-solving, and improved social interactions. Additionally, the physical advantages of sleeping with a partner include lowered blood pressure, a stronger immune system, and reduced inflammation.
However, it is important to note that not all couples experience these feelings of security. Individuals with insecure attachment styles may not be able to use their partner as a secure base, and may not receive the same stress-buffering benefits of sleeping with a partner.
Overall, increased feelings of safety and security due to the presence of a trusted partner can lead to better sleep quality and improved mental and physical health.

Improved relationship quality
Sharing a bed with a partner can improve the quality of your sleep, which in turn can improve your relationship. Research has shown that couples who sleep side by side experience increased and less disrupted rapid-eye movement (REM) sleep, which has been linked to memory organisation, emotion regulation, creative problem-solving, and social interactions.
Undisturbed REM sleep can protect you from sleep deprivation and sleep disorders such as insomnia, which are known to increase the risk of developing mental health conditions such as depression. Improved REM sleep can also contribute to better emotional processing and resilience, enhancing your overall psychological well-being.
Additionally, the physical touch and proximity of sleeping with a partner can lead to the release of oxytocin, also known as the "cuddle chemical" or "love hormone". Oxytocin promotes feelings of empathy, trust, relaxation, and reduced anxiety, all of which can contribute to improved relationship quality.
Furthermore, the simple act of sharing a bed and creating physical closeness with your partner can strengthen your emotional bond and sense of security within the relationship. This can lead to reduced stress and improved mental health, making it easier to fall asleep and promoting better sleep quality.
While sharing a bed with a partner can have numerous benefits, it is important to note that not all couples experience improved sleep or relationship quality. Individual differences, attachment styles, and sleep habits can influence the impact of partnered sleep on the relationship. Some individuals may prefer sleeping alone or may find that their partner's sleep habits disrupt their sleep, leading to a preference for separate sleeping arrangements.

Health benefits, such as lower blood pressure
Sleeping with a partner can have a positive impact on your health and well-being. It can help you fall asleep faster and improve your overall sleep quality. According to attachment theory, romantic partners serve as a source of safety and security, which can reduce vigilance and promote relaxation, making it easier to fall asleep. This sense of security can also buffer against daily stress, reducing physiological arousal and contributing to sounder sleep.
Women in cohabiting relationships may alter their bedtimes or wake-up times to match their partners, resulting in longer total sleep time. Additionally, the stress-relieving feelings of comfort and security gained by sleeping with a partner can make it easier to fall asleep and enhance sleep continuity.
Sleeping with a partner is associated with longer sleep durations and better sleep quality. A 2020 study found that it is linked to 10% more rapid eye movement (REM) sleep, which is crucial for cognitive functions like learning and memory. Furthermore, a 2022 study published in the Sleep Journal found that sleeping with a partner improved overall sleep quality and well-being, reducing depression, anxiety, stress, sleep apnea, and insomnia.
In terms of health benefits, such as lower blood pressure, sleeping with a partner can indeed have a positive impact. Sleep is essential for maintaining healthy blood pressure. The quantity and quality of sleep can significantly impact blood pressure readings. During sleep, blood pressure naturally dips, allowing the cardiovascular system to recover from the demands of being awake. This nocturnal dipping is crucial for cardiovascular health, and inadequate sleep can disrupt this process, leading to elevated blood pressure and an increased risk of hypertension.
Therefore, by improving sleep quality and duration, sleeping with a partner can indirectly contribute to lower blood pressure and a reduced risk of hypertension. Additionally, the feelings of security and reduced stress associated with sleeping with a loved one can also positively impact blood pressure by lowering stress hormone levels and physiological arousal.
In summary, sleeping with a partner can lead to better sleep quality and longer sleep duration, which indirectly contributes to lower blood pressure and improved cardiovascular health. The feelings of security and reduced stress associated with sleeping with a partner can also positively impact blood pressure by lowering stress hormone levels and physiological arousal.

Enhanced REM sleep
Sleeping with a partner is associated with increased rapid-eye movement (REM) sleep and greater sleep synchronization. According to a study published in Frontiers in Psychology, couples sleeping together experienced approximately 10% more REM sleep, longer undisturbed REM sleep fragments, and greater sleep synchronization despite increased limb movements. This positive feedback loop may further enhance and stabilize REM sleep, which is beneficial as REM sleep improves social interactions and reduces emotional stress.
REM sleep is a vital stage of sleep that accounts for about 25% of total sleep time and is characterized by rapid eye movements behind closed eyelids. It is during this stage that most dreams occur, and brain activity resembles that of a waking state. The first episode of REM sleep is usually brief, lasting only a few minutes, but subsequent episodes lengthen, with the final one lasting up to half an hour.
The benefits of REM sleep extend beyond just memory consolidation. It aids in brain development, particularly the central nervous system, which includes the brain and spinal cord. This could explain why newborns and infants require a significant amount of REM sleep. Additionally, REM sleep may offer protection against dementia. Research suggests that a 1% reduction in REM sleep corresponds to a 9% increase in the risk of developing dementia.
The presence of a romantic partner during sleep provides feelings of safety and security, contributing to better sleep quality. According to attachment theory, romantic partners serve as a secure base, fostering feelings of protection and comfort. This sense of security helps individuals relax and fall asleep more easily, resulting in sounder sleep.
While sharing a bed with a partner has its advantages, it is important to consider individual differences in attachment styles. Persons with insecure attachment styles may not experience the same stress-buffering benefits and could find that their sleep is disturbed by their partner's movements or sleep disorders. Nevertheless, for those with secure attachment styles, co-sleeping can lead to enhanced REM sleep and improved overall sleep quality.
