You likely sleep better with your partner due to a combination of hormonal and psychological factors, specifically related to the release of oxytocin.
The Science Behind Better Sleep
Sleeping next to your partner isn't just about comfort; it triggers a cascade of physiological changes that promote relaxation and deeper sleep. Here's how it works:
| Factor | Benefit |
|---|---|
| Oxytocin | Increased production in both men and women. Often called the "love hormone," oxytocin fosters relaxation, calmness, and reduces stress and anxiety. |
| Estrogen | Increased production in women. Works with oxytocin to help women maintain an ideal body temperature and get more restful sleep. |
| Reduced Stress | The presence of a loved one provides a sense of security and comfort which, in turn, lowers stress hormones, such as cortisol, allowing the body to relax and settle into sleep. |
How These Hormones Help
The combined effect of oxytocin and estrogen (in women) on the body is profound for enhancing sleep:
- Relaxation: Oxytocin promotes a sense of calm and reduces feelings of stress and anxiety, making it easier to fall asleep.
- Body Temperature Regulation: Estrogen, when boosted by the physical presence of a partner, also contributes to the regulation of body temperature. This is key since the body's core temperature must lower in preparation for sleep.
- Deeper Sleep: The relaxation effect of oxytocin and optimal body temperature regulation helps achieve deeper, more restorative sleep cycles. This is beneficial for overall physical and mental health.
Practical Tips
Although the physical presence of a partner is beneficial for sleep, remember:
- Maintain Good Sleep Hygiene: Continue to prioritize a regular sleep schedule, a comfortable sleep environment, and avoid stimulating activities close to bedtime.
- Communication: Ensure you and your partner are both sleeping comfortably and not disturbed by one another.
- Individual Needs: Recognize individual sleeping needs. Even if sleeping together is beneficial, address any unique needs with patience and communication.
In conclusion, sleeping next to your partner increases the production of hormones like oxytocin and estrogen (in women), which foster relaxation and contribute to more restful sleep. The increased level of these hormones is a key factor in why you likely experience a better night's sleep compared to sleeping alone.
