Happy wife, happy life, says a man in Singapore, and experts confirm it’s true – being married to an optimist improves your mental health
- Having a positive partner improves our mental well-being and optimistic people contribute to their partners’ health by reducing their risk of cognitive decline
- A Singaporean couple share how their marriage and mental health have benefited from each other’s encouragement and support

Colin Teo is about as positive and optimistic as they come.
His wife of 17 years, Ho Joo Kah, describes Teo as a “half glass full” type of man. She says it’s his sunny nature and upbeat attitude that have helped the Singaporean couple and their four children navigate the challenges they’ve experienced together.
“Whatever my worry, Colin always listens to me and encourages me to look on the bright side,” says Ho, 47.
“His positive approach to life and unwavering support for me are, I believe, a big part of why we enjoy a close and loving relationship – and why I’m a happy wife.”
“When Joo Kah is happy, I’m happy,” says Teo, 48, a urologist. “In a marriage, you’re bound to experience rough patches, so it’s important for both partners to be positive and hopeful for each other. If you can’t bring joy to your partner or encourage them to believe in anything good, how can you have a fulfilling relationship?”
