The Short Version
Strong peer-reviewed evidence supports both time management and social support as beneficial strategies for university students' wellbeing and stress reduction. Multiple systematic reviews and meta-analyses confirm these associations. However, the claim slightly overstates the evidence by framing these as strategies for "establishing healthy boundaries" specifically — the strongest empirical sources demonstrate wellbeing and stress outcomes rather than boundary-setting per se. The core practical message remains sound, but effect sizes for social support vary, and these strategies are not universally effective under heavy academic demands.
