Discomfort or Choking Sensation: Some individuals might find it uncomfortable or may experience a choking sensation while drinking water in a standing position, especially if they're drinking rapidly or taking large gulps.
Digestive Discomfort (Traditional Beliefs): According to some traditional medicine systems, such as Ayurveda, standing while drinking water may disrupt the natural digestive processes, potentially leading to digestive discomfort or imbalances.
Potential for Reflux: In some cases, standing and drinking water quickly might increase the chances of gastroesophageal reflux (GERD) or heartburn, particularly if someone is prone to these conditions.
Inefficient Hydration: Some individuals might find it harder to control the amount of water consumed when standing, leading to inefficient hydration or potentially not drinking enough water throughout the day.
No Direct Scientific Evidence: It's important to note that while these side effects are occasionally mentioned anecdotally or in traditional beliefs, there's a lack of concrete scientific evidence proving direct harm or adverse effects from drinking water while standing.
