Which of the following is a common non-pharmacological intervention for nausea?

Ginger is a well-known non-pharmacological intervention for managing nausea. It has been widely studied and documented for its antiemetic properties, making it a popular natural remedy. The active compounds in ginger, such as gingerol and shogaol, are believed to enhance gastric emptying and reduce feelings of nausea, particularly in cases such as morning sickness in pregnancy, motion sickness, and postoperative nausea.

While other options may provide some relief or comfort, they are not primarily recognized for their anti-nausea effects. Ice cream might be soothing or appealing when someone is feeling unwell, but it does not have specific antiemetic properties. Caffeine, a stimulant, can sometimes exacerbate nausea rather than alleviate it. Mint is often used for digestive issues and can provide mild relief from nausea for some individuals, but it is not as widely recognized or as extensively studied as ginger for its effectiveness in combating nausea. Thus, ginger stands out as the most established non-pharmacological intervention for this purpose.
