Should I wear anything under my scrubs?

Good day, I have a question regarding attire for a professional setting. Specifically, I'm wondering if it's necessary or advisable to wear anything underneath my scrubs when working in a healthcare environment. Are there any specific considerations I should be aware of, such as comfort, hygiene, or regulatory requirements? Additionally, would the choice of undergarments potentially impact my work performance or the patient experience in any way? Thank you for your guidance on this matter.
