Love and Sleepiness: Why Do We Get Sleepy Around Those We Love?

Love and Sleepiness: Why Do We Get Sleepy Around Those We Love?

When we are around someone we love, we may find ourselves feeling more relaxed and, at times, even sleepy. This phenomenon can be both intriguing and puzzling. In this article, we will explore the possible reasons behind this feeling of sleepiness when we are with someone we love, drawing insights from scientific research and psychology.

Understanding the Connection Between Love and Sleepiness:

1. Oxytocin: Often referred to as the "love hormone," oxytocin plays a significant role in social bonding, trust, and attachment. When we are close to someone we love, our brain releases oxytocin, which helps us feel more connected and relaxed. This calming effect can lead to feelings of sleepiness, as our body and mind enter a state of relaxation and comfort. [Link:]

2. Emotional safety: Being around someone we love can create a sense of emotional safety and security. When we feel secure, our brain recognizes that we are in a safe environment, which may prompt our body to relax and allow us to become sleepy. This feeling of safety can help reduce stress and anxiety levels, further contributing to our sense of relaxation and drowsiness.

3. Parasympathetic nervous system activation: The parasympathetic nervous system, often called the "rest and digest" system, is responsible for calming our body and helping us unwind. When we are with someone we love, our parasympathetic nervous system may become activated, promoting a sense of relaxation and ultimately leading to feelings of sleepiness.

4. Physical touch: Physical touch, such as hugging, holding hands, or cuddling, can also contribute to feelings of sleepiness around someone we love. Touch can stimulate the release of oxytocin and activate the parasympathetic nervous system, creating a calming effect and promoting relaxation. The warmth and comfort associated with physical touch can also make us feel sleepy.

5. Emotional exhaustion: Experiencing intense emotions, such as love, can be mentally and emotionally exhausting. Our brain uses a significant amount of energy to process emotions, and when we are emotionally exhausted, we may feel sleepy as our body tries to conserve energy and recharge.

6. Mirror neurons: Mirror neurons are specialized brain cells that help us understand and empathize with the emotions and actions of others. When we are with someone we love, our mirror neurons may become activated, causing us to mimic their emotions and behaviors. If our loved one is feeling relaxed or sleepy, we might find ourselves feeling the same way.

7. Social entrainment: Social entrainment is the process by which our biological rhythms, such as sleep patterns, become synchronized with those of people around us. When we spend time with someone we love, our sleep patterns may become aligned with theirs, causing us to feel sleepy when they do.

8. Positive associations with sleep: If we have fond memories or positive associations with sleep, such as cuddling with a loved one, we may be more likely to feel sleepy when we are with someone we love. Our brain may link the feeling of love and comfort with sleep, prompting us to become drowsy in their presence.


Feeling sleepy around someone we love can be attributed to various factors, such as the release of oxytocin, emotional safety, activation of the parasympathetic nervous system, physical touch, emotional exhaustion, mirror neurons, social entrainment, and positive associations with sleep. Understanding these factors can help us appreciate the unique connection between love and sleepiness and deepen our understanding of the complex nature of human emotions and relationships.
