(63) The World Health Organization (WHO) emphasizes purification to reduce exposure to toxins and heavy metals. (64) Additionally, cleaner water supports digestion and nutrient absorption, promoting overall health. (65)

7. Drink at a Comfortable Temperature

Drinking warm water at a comfortable temperature (120-140°F or 49-60°C) prevents irritation and optimizes hydration [Epstein & Moran]. ({%  trusted %}) Studies suggest that extremely hot water can damage the esophagus, while lukewarm water enhances digestion and metabolism. (66) Research also highlights that proper hydration temperature influences thermoregulation and overall comfort. (67) The World Health Organization (WHO) recommends maintaining a safe and moderate temperature for drinking water to reduce risks of burns and discomfort. (64)

Drawbacks of drinking warm water in the morning

While drinking warm water in the morning offers benefits, excessive intake may cause burns, disrupt digestion, or dilute stomach acids. Overconsumption can also lead to electrolyte imbalance and frequent urination.

1. Risk of Burns

Drinking warm water at a comfortable temperature (120-140°F or 49-60°C) prevents irritation and optimizes hydration. (68) Studies suggest that extremely hot water can damage the esophagus, while lukewarm water enhances digestion and metabolism. (66) Research also highlights that proper hydration temperature influences thermoregulation and overall comfort.

(82) Research highlights that enamel demineralization occurs when exposed to acidic and warm beverages, increasing wear over time. (83) Additionally, prolonged exposure to warm water may soften enamel, reducing its protective properties and increasing sensitivity. (84)

Myths vs. Facts about Drinking Warm Water

There are many claims about the benefits of drinking warm water, but not all of them are backed by science. Here’s a detailed breakdown of common myths vs. facts to help clarify what warm water can and cannot do for your health.

1. Myth: Drinking Warm Water Aids in Weight Loss

Fact: While drinking water in general is beneficial for weight management, there is no direct evidence that warm water itself accelerates weight loss. Hydration supports metabolism and digestion, which can help with weight control, but the temperature of the water does not play a significant role in fat burning. Instead, factors like diet, exercise, and caloric intake determine weight loss success.

What Science Says: Research shows that drinking water before meals increases satiety and reduces calorie intake, but whether warm water has an added advantage is uncertain. Some studies suggest cold water slightly boosts calorie burning because the body must expend energy to heat it, making it technically more beneficial for metabolism than warm water.

2. Myth: Warm Water Detoxifies the Body

Fact: The human body naturally detoxifies itself through organs like the liver, kidneys, and digestive system. Drinking warm water may support hydration and digestion, but it does not “flush out toxins” faster than regular or cold water. The concept of detox through warm water is largely a myth promoted by alternative wellness trends.

What Science Says: The body continuously removes toxins through urination, sweating, and bowel movements. Proper hydration helps these processes, but the temperature of water does not enhance detoxification. Detox diets and cleansing drinks often lack scientific backing.

3. Myth: Warm Water Improves Digestion

Fact: There is limited scientific evidence that drinking warm water significantly enhances digestion. Some proponents argue that warm water stimulates digestive enzymes, but digestion is a complex process controlled by the gut, stomach acids, and enzymes, not the temperature of consumed fluids.

What Science Says: Warm water can help relax intestinal muscles, which may aid people with constipation or bloating. However, no conclusive research states that warm water is essential for good digestion. Drinking enough water of any temperature is the key to supporting a healthy digestive system.

4. Myth: Drinking Warm Water Prevents Colds and Flu

Fact: Warm water may soothe a sore throat and relieve congestion, but it does not prevent colds or flu. Viral infections are caused by viruses, and warm water does not have the ability to kill them or prevent their spread.

What Science Says: Warm fluids can temporarily ease symptoms by thinning mucus and keeping the throat moist. However, hand hygiene, a balanced diet, and a strong immune system are more effective in preventing colds and flu than drinking warm water.

5. Myth: Warm Water Hydrates Better Than Cold Water

Fact: The temperature of water does not affect its hydrating properties. Warm water and cold water hydrate the body equally well. The only difference is personal preference—some people find warm water more comfortable, while others prefer cold water for refreshment.

What Science Says: Studies show that cold water is often absorbed faster due to quicker gastric emptying, which may be beneficial in hot weather or during exercise. However, in cold climates, warm water may be more soothing and help regulate body temperature.

Conclusion

Incorporating warm water into your morning routine offers numerous health benefits, from improving digestion and detoxification to boosting metabolism and enhancing circulation. This simple habit supports hydration, skin health, and overall well-being. By drinking warm water regularly, you can promote a healthier digestive system, reduce stress, and even aid in weight management. For added benefits, consider infusing it with lemon, honey, or herbal ingredients. Making this a daily practice can contribute to long-term health improvements, ensuring a refreshing and energized start to your day.
