The internet is filled with claims about the supposed health benefits of drinking hot or warm water. From improved digestion to weight loss, many videos and posts promote this habit as a wellness secret. However, medical professionals say the reality is more nuanced. The trend has roots in traditional Chinese and Ayurvedic medicine, where warmth is linked to improved “chi” – the body’s energetic force – and digestive health.

Cultural Significance and Relaxation

Drinking hot water is deeply embedded in many cultures, particularly through tea consumption. Doctors emphasize that the soothing and relaxing effect of warm fluids is a genuine benefit. Stress reduction alone can positively impact overall health. If hot water is part of your routine or cultural practice, continuing it is fine. But those seeking specific health outcomes may be disappointed.

Hydration and Digestive Flow

Regardless of temperature, drinking water is essential for hydration, supporting optimal bodily function. Warm liquids can facilitate movement through the digestive tract by relaxing sphincters – the muscles controlling flow from the mouth to the colon. This stimulation can aid bowel movements and even trigger the gastrocolic reflex, a natural process that encourages defecation.

However, drinking water of any temperature helps with defecation, as stretching the stomach signals the gastrocolic reflex.

The Truth About Digestion and Weight Loss

Contrary to popular belief, hot water doesn’t necessarily aid digestion. Studies show that both hot and cold drinks can slow gastric emptying compared to body-temperature fluids. The digestive system functions best at 37°C (98.6°F); extreme temperatures can temporarily disrupt motility.

Furthermore, there’s no scientific evidence to support claims that hot water detoxifies, boosts metabolism, or causes weight loss. Weight loss benefits stem from replacing high-calorie beverages with water, a benefit shared by cold water too.

Placebo Effect and Practicality

The measurable effects of drinking hot water remain unclear. Some individuals may experience benefits, but the extent to which this is due to placebo is unknown.

Doctors agree that drinking hot water isn’t harmful and can be part of a wellness routine if it makes you feel better. But it’s crucial to understand that no major health changes are guaranteed.

The scientific evidence isn’t there to suggest that hot water, uniquely, detoxifies, improves digestion, boosts metabolism, or causes weight loss. However, if it aids your mood or rituals, that can be beneficial.
