Sleep-deprived spouse harms your diet

A study shows your partner's poor sleep affects your eating habits.

In brief

A study shows your partner's poor sleep affects your eating habits. Poor sleep in one partner reduces both partners' efforts to eat healthily. Originally reported by New York Post.

Sleep affects diet

A man snores with his mouth open while his wife covers her ears with a pillow, visibly annoyed.

Poor sleep links to unhealthy eating habits for both partners in a study of 204 cohabiting couples.

“People with a sleep-deprived partner were essentially saying they have less confidence in their ability to follow a healthy diet, so they engage in less effort to do so.”
