Meal deals and extra support for mental health are part of a university's response to higher living costs.
University of Wales Trinity St David (UWTSD) has seen a "significant increase" in the number of applications for hardship funds.
The university, in south-west Wales, said Christmas was especially difficult for students with children.
The Welsh government said it offered the "most generous student support in the UK".
One student said the higher costs were limiting opportunities to socialise and take part in trips and clubs.
