“Closeness at night creates closeness in life.”

Research suggests that couples who sleep naked tend to report higher relationship satisfaction — and the reason goes deeper than comfort. Here’s what science says: • Skin-to-skin contact boosts oxytocin, the “bonding hormone” that increases trust, connection, and emotional closeness. • Sleeping naked helps regulate body temperature, leading to better, deeper sleep, which directly influences mood and relationship harmony. • Physical intimacy (even without sexual activity) reduces cortisol, the stress hormone, making couples calmer and more affectionate. • Studies show that couples who share more physical closeness at night feel more supported and secure during the day.
