If you’re looking to improve your health, some people may tell you to drink warm water every day. While drinking warm water may sound like a healthy practice, there is little evidence suggesting that warm water is significantly better for your health than room-temperature or cold water.

With all of the different health fads out there, odds are you’ve heard someone say that drinking warm water is great for your health. But is that actually true? Our friendly Synergy Science™ Hydro Bro dives into this claim. Check out his video here!

What Is Warm Water Supposed to Help With?

Many people claim that drinking warm water is supposed to help with a variety of health issues, including digestion and constipation, detoxification, skin issues, and stress. While some people may experience these benefits, is the idea of drinking warm water a myth, or is it supported by science? Let’s take a look at what the studies say.

Drinking warm water for health benefits may be more myth than science.


When you don’t drink enough water, your small intestine will absorb the majority of the water you do consume. If you’re not consuming enough, this can cause dehydration and lead to more difficult bowel movements. (1) Drinking warm water is supposed to help break down food faster than colder water, thus helping to reduce your risk of constipation and promote proper digestion.

This benefit makes sense in theory, but what does science say? A handful of studies actually support this specific benefit of drinking warm water. One study found that drinking warm water had a favorable impact on intestinal movement. (2) A scientific article states that consuming warmer beverages can stimulate the overall physiological process of digestion better than cold or room-temperature water because warm water helps lubricate the body more efficiently.

Detoxifying the body is an increasingly popular health practice. Whether your detox involves a juice cleanse, a trip to the sauna, fasting, or some other method, it is important to support a healthy body. However, some people claim that drinking warm water is enough to help get those toxins out of your body. The claim: drinking warm water raises your body temperature, which causes you to sweat. Sweating releases toxins, thus helping to cleanse your body and your pores. (1)

While some people may find that drinking warm water raises their body temperature enough to sweat out toxins, there are no scientific studies to back up this claim. If drinking warm water works for you, that’s great! Otherwise, you can always try the Synergy Sauna™, which gives you an at-home spa experience that will make you sweat as much as a 30-minute run in just 10 minutes! Now that’s the kind of detox we all need.

Colds and Stuffiness

If you’ve ever had a cold or stuffy nose, you may have reached for a cup of warm water or tea to help relieve your symptoms. This age-old remedy is simple and effective for many people, and there are a few studies that back up this tradition.

One study found that sipping hot water helped increase mucus velocity better than drinking cold water or even drinking warm water through a straw. As a result, you may be able to experience less congestion and fluid in your upper respiratory tract. (4) Another study found that warm water not only helped “cure bacterial cold-water disease,” but it also supported immune defense against the causative bacteria Flavobacterium psychrophilum. (5)

Skin Care

Some people believe that drinking warm or hot water can help give you better skin because it can increase your body temperature and thus help flush out toxins that can clog your pores. Others suggest that drinking warm water daily can keep your skin hydrated and moisturized. In addition, still others claim that warm water can help increase circulation, which helps deliver nutrients to skin cells, ultimately resulting in healthier skin. (6)

While these theories may be true, there are extremely limited studies on how warm water can benefit your skin. One study shows that alternating between cold and warm baths (instead of drinking warm water) can help increase blood flow in the skin. (7)

On the other hand, one study found that drinking water in general, rather than specifically warm water, may be all you need. The skin is 30% water, which helps with its elasticity, plumpness, and resilience. Drinking enough water, especially for those who have a lower water intake, can improve skin density and thickness. However, this study does not support the idea that even drinking regular water helps with wrinkles or other signs of aging. (8)

Many say that drinking warm water can help boost your overall circulation. This is because warm or hot water is a vasodilator, which means that it expands the blood vessels and thus improves circulation. As a result, you can experience reduced pain and increased muscle relaxation. (1) While all of these benefits sound great and some people may experience them, there are no scientific studies that support these claims.

Weight Loss

A common belief about drinking warm water is that it helps with weight loss. While some people may notice this benefit, there are more studies that focus on the benefits of drinking water in general to help with weight loss, rather than drinking warm water specifically.

One study found that drinking 500 mL (16.9 oz.) of water prior to eating a meal can help reduce energy intake and promote more weight loss when paired with a low-calorie diet, specifically among those who are middle-aged or older. (9) Another study found that increasing water intake in general is associated with the loss of both body weight and fat over time. (10)

When it comes to drinking warm water specifically, one study found that drinking 500 mL of water helped increase a person’s metabolic rate by 30% and created a thermogenic response (raising of the body temperature) of about 100 kJ. When the water was warmed to a temperature between about 71°F and 98°F (22°C and 37°C), it accounted for 40% of the thermogenic effect. (11) This shows that drinking warmer water can create a greater thermogenic effect and potentially help increase metabolism.

Reduce Stress

Depending on who you talk to, some people believe that drinking warm water can help reduce feelings of stress and anxiety. This is because warm water creates a soothing effect. However, many people with high stress and anxiety may reach for a cup of warm coffee or tea instead of plain warm water. As a result, it is unclear whether the stress relief comes from the warm water itself, the caffeine, or the other ingredients in a tea blend. At the moment, there are no scientific studies to support the idea that warm water helps relieve feelings of anxiety or stress.

Supporting a Healthy Body With Water

If you’re looking for a simple way to boost your health, you can certainly try incorporating warm water into your daily routine. However, if you’re looking for something that is backed by over 1,000 different studies and offers benefits like improved digestion, reduced signs of aging, improved immune function, healthy weight loss, and so much more, then you need hydrogen water.
