MRIS 21C has a fully-equipped infirmary, Wellness Zone, an essential feature of every school. It is meticulously handled by an experienced Doctor who is expert in addressing first-aid and other medical treatments. The Wellness Zone is packed with nebulisers, inhalers, oxygen cylinders, and availability of the most vital medicines that are kept refrigerated at all times. 

A proper health record of each student is well-maintained through checkup rounds taken by the doctor continually, which is shared with the parents by the end of each academic session. The School also organises an annual eye and dental  check-up for instilling in our students the importance of eye and dental hygiene.
