This means that even subtle signals — breathing changes, touch, movement — can be interpreted by the female brain as “something to pay attention to.” Men tend to sleep well regardless of small relationship tensions, while women’s sleep quality can drop sharply after conflict. Sharing a bed doesn’t remove these responsibilities — but it does add disturbances. Women feel these changes more sharply, especially on shared mattresses that don’t isolate motion well.
“Women experience more fragmented sleep than men overall, and co-sleeping amplifies this effect due to differences in physiology and sensitivity.” “The quality of a woman’s sleep is often directly tied to the emotional climate of the relationship.” “Men and women have biological clocks that don’t always synchronize, and this creates natural friction in co-sleeping.” Scandinavian couples swear by this — each partner gets their own duvet to minimize heat, movement, and blanket stealing.
