Lemon water has become a go-to morning drink for many Americans looking to kickstart their day with a healthy habit. Made by mixing fresh lemon juice with warm or room-temperature water, this simple drink has been linked to better hydration, improved digestion, and overall wellness.
A 2014 study in Nutrition Journal highlighted that daily lemon intake may positively affect blood pressure and increase citric acid levels in the body. Dr. Saurabh Sethi, a gastroenterologist trained at AIIMS, Harvard, and Stanford, recently shared insights on the lesser-known benefits of lemon water.
Hydration Boost
Dr. Sethi notes that roughly 75% of adults are chronically dehydrated. Adding lemon to water can make drinking fluids more appealing, helping with energy, digestion, and focus. Its natural electrolytes and vitamin C help replenish hydration after workouts or during hot weather, while its mild alkalizing effect supports metabolism.
A Natural Source of Vitamin C
One lemon provides about 35 mg of vitamin C—roughly 40% of daily needs. This essential nutrient strengthens immunity, supports collagen production for skin health, enhances iron absorption, and protects cells from oxidative stress.
Supports Digestion
Warm lemon water may stimulate gastric juices and bile flow, especially helpful for those with low stomach acid. A morning glass can aid in digestion, relieve bloating, and promote regular bowel movements. While lemon water itself doesn’t “detox” the body, it can help the liver and digestive system work efficiently.
Soothing and Gentle
Warm lemon water is easier on the stomach, although vitamin C begins to break down above 70°C. Drinking it warm, rather than piping hot, ensures you still get some of its benefits.
Caution for Acid Reflux and Teeth
Citrus can worsen symptoms for up to 20% of people with GERD. Dr. Sethi recommends avoiding lemon water on an empty stomach if you experience burning or bloating. Because lemon is highly acidic (pH around 2), it’s best consumed through a straw in one sitting, followed by rinsing with plain water to protect tooth enamel.
The Takeaway
Lemon water is a simple, gut-friendly ritual. It helps with hydration, supports digestion, and may benefit the microbiome. While it’s not a miracle detox drink, incorporating it into your morning routine can be a refreshing and healthy habit—just be mindful of reflux and tooth health.
