Loma Linda University actively promotes a healthy moral lifestyle consistent with Seventh-day Adventist Christian principles. Therefore, the University expects students to attend the midweek University chapel service designed to focus the University community on its mission and to facilitate students' personal journey with God.

For Seventh-day Adventists, a basic tenet of our belief is worshiping on Saturday. Seventh-day Adventists observe Sabbath from sundown on Friday evening until sundown on Saturday evening. Consequently, the school offices and libraries close early on Friday afternoon and are not open on Saturdays. The library is open on Sunday.

The University expects students to exclude alcohol, tobacco products, cannabinoids, and illegal drugs from their lives while enrolled. When a student chooses a career in a professional field, it is important to portray a professional image.  Loma Linda University has created professional standards of appearance that will place our graduates in the highest level of professional health care expectations.  These standards include no visible tattoos or body piercings apart from simple earrings.  For further information, please visit Values and Lifestyle. Information on the professional expectations of School of Medicine students is provided in the Student Handbook.
