Benefits of Drinking Hot Water: How Does it Affect Your Body?

Water is a crucial element for overall well-being, and the consumption of warm or hot water may offer additional advantages such as aiding digestion, enhancing circulation, and reducing stress. Whether one prefers warm or ice-cold water, there is no distinction in terms of hydration. However, the varying temperatures can evoke different sensations. Warm beverages provide comfort, while a glass of chilled water imparts a more refreshing feeling.

While scientific research on the benefits of hot water is limited, proponents of alternative health argue that it is a simple method to enhance health. Many individuals find solace and benefits in drinking plain hot water or hot lemon water. Hot water contributes to hydration and may aid in alleviating congestion, improving digestion, relieving stress, and creating a warmer sensation.

Regardless of temperature, staying hydrated by drinking water is essential for maintaining a healthy body. Some assert that hot water, in particular, may enhance digestion, relieve congestion, and induce relaxation, as opposed to cold water. Most health benefits associated with hot water are anecdotal, given the limited scientific research in this field. Nonetheless, many individuals report experiencing positive effects, particularly when consuming hot water in the morning or before bedtime.

For those consuming hot beverages, research recommends an optimal temperature ranging from 130 to 160°F (54 to 71°C) to avoid burns or scalds. For an additional health boost and a dose of vitamin C, incorporating a twist of lemon into hot water to make lemon water is suggested. This article explores the evidence for these claims. Medflick has brought you the answers for the Benefits of Drinking Hot Water: How does it Affect Your Body?

What are the Benefits of Drinking Hot Water?

1. May Assist in Digestion

Regular water consumption supports the continual movement of the digestive system. As water traverses the stomach and intestines, the body becomes more adept at eliminating waste.

There is a belief that drinking hot water is particularly beneficial for activating the digestive system. The notion is that hot water may aid in dissolving and dispersing food that the body may have struggled to digest.

While additional research is necessary to validate this potential benefit, a study from 2016 indicated that warm water might have positive effects on intestinal movements and gas expulsion following surgery. In the interim, if you find that drinking hot water aids your digestion, there is no harm in utilizing it as a remedy.

2. Maintains Hydration

While some evidence suggests that cool water is optimal for rehydration, drinking water at any temperature plays a crucial role in sustaining hydration. The Institute of Medicine recommends that women aim for 78 ounces (2.3 liters) of water daily, while men should target 112 ounces (3.3 liters). These figures encompass water from various sources, including food like fruits and vegetables.

Additional water intake is necessary for individuals who are pregnant, breastfeeding, involved in strenuous activities, or working in hot environments. Consider beginning your day with a serving of hot water and concluding it with another. Water is essential for executing virtually every fundamental bodily function, underscoring its paramount importance.

3. May Alleviate Nasal Congestion

Inhaling the gentle steam generated by a cup of hot water can potentially ease nasal congestion. Holding the hot water cup and taking a deep breath of the vapor may help loosen blocked sinuses and provide relief from a sinus headache. Hot water with natural home remedies like asafoetida and/or honey helps in reducing nasal and clearing chest congestion.

Given the presence of mucous membranes in the sinuses and throat, the act of drinking hot water might contribute to warming this area, offering soothing effects on a sore throat caused by mucus accumulation. According to an earlier study from 2008, a hot beverage like tea demonstrated swift and lasting relief from symptoms such as a runny nose, cough, sore throat, and fatigue, proving more effective than the same beverage at room temperature.

4. May Aid in Alleviating Constipation

Dehydration is a prevalent factor contributing to constipation. In many instances, the consumption of water proves to be an effective method for relieving and preventing constipation. Maintaining hydration levels assists in softening stool, facilitating easier passage. Regular consumption of hot water may contribute to maintaining regular bowel movements.

5. May Support the Body's Detoxification Systems

While concrete evidence regarding the specific benefits of hot water in this context is lacking, a study from 2020 revealed that increased water intake can aid in safeguarding the kidneys by diluting waste materials in the blood.

As suggested by the Arthritis Foundation, the consumption of water plays a crucial role in purging the body. It contributes to combating inflammation, maintaining well-lubricated joints, and preventing gout.

6. Alleviates Shivering in Cold Conditions

A study from 2017 discovered that, while the natural response of the body in cold environments is to shiver, the consumption of warm fluids can mitigate shivering. Participants in the study wore suits infused with slightly above-freezing water and drank water at various temperatures, including up to 126°F (52°C). The findings revealed that consuming hot water promptly assisted the participants in expending less effort to maintain their body temperature. This aspect could prove beneficial, particularly for individuals working or exercising in cold conditions.6

7. May Alleviate Symptoms of Achalasia

Achalasia is a condition characterized by difficulties in moving food down the esophagus into the stomach. Individuals with achalasia encounter challenges in swallowing, often feeling as though food gets stuck in the esophagus instead of progressing to the stomach, a condition known as dysphagia. While the exact reasons remain unclear, an earlier study from 2012 found that drinking warm water may offer comfort to individuals with achalasia, aiding in more comfortable digestion.

8. Enhances Circulation

Optimal blood circulation plays a vital role in various aspects, ranging from blood pressure to the risk of cardiovascular disease. Indulging in a warm bath causes the expansion of circulatory organs, such as arteries and veins, promoting more efficient blood transport throughout the body. While limited research supports the idea that drinking hot water may have a similar circulatory benefit, the warmth derived from consuming hot water or bathing in the evening may contribute to relaxation and preparation for a restful sleep.

9. May Enhance Central Nervous System Function

Insufficient water intake, whether warm or cold, can negatively impact the functioning of your nervous system, ultimately influencing mood and brain function. A study from 2019 has indicated that consuming water can enhance the activity of the central nervous system and positively affect mood. This research demonstrated an increase in participants' brain activity during demanding tasks, coupled with a decrease in self-reported anxiety, when they consumed water.

10. May Reduce Stress Levels

Given that drinking hot water aids in enhancing central nervous system functions, it can potentially lead to a reduction in anxiety. According to a study from 2014, a decrease in water intake resulted in diminished feelings of calmness, satisfaction, and positive emotions. Consequently, maintaining proper hydration levels may positively impact mood and levels of relaxation.

What are the Side Effects of Drinking Hot Water?

Excessive hot water consumption can cause esophageal tissue damage, tongue scalding, and taste buds to burn. While consuming hot water, it is critical to exercise extreme care. Cool water, instead of hot water, is the best choice for rehydration. The main concern with drinking hot water is the possibility of burns. Even water that feels pleasantly warm to the touch can cause tongue or throat burn. Water that's too close to boiling temperature should be avoided, and a small amount ought to be checked before taking a large gulp to mitigate the potential side effects. Drinking hot water using a covered, insulated cup is advised to reduce the risk of spills and burns. 

Caffeinated coffee or tea can trigger jitteriness or over-caffeination. This can be avoided through limiting coffee and tea consumption or replacing caffeine-laden drinks with plain warm water. Drinking hot water, in general, has no negative effects and has been deemed safe for use as a remedy.

What is the Right Temperature for Drinking Hot Water?

Hot drinks like coffee or tea are frequently served at temperatures close to boiling. There's no need for individuals to jeopardize getting burned to enjoy the advantages of hot water. If you don't like hot water, you should choose water that is either body temperature or just a little bit warmer.

A study from 2008 indicated an ideal drinking temperature of 136°F (57.8°C) for coffee. This temperature minimizes the risk of burns while still providing the enjoyable warmth of a hot beverage.
