1) What are the benefits of drinking hot water?
Although there is little scientific research on the benefits of drinking hot water, alternative health advocates argue that hot water is an easy way to improve health. In this article, we look at the evidence.
Benefits
While drinking water of any temperature can support overall well-being, drinking hot water is thought to provide a range of additional health benefits.
People have consumed hot drinks for thousands of years. Folk medical literature is filled with stories of how hot water can improve health, but researchers have only just begun to look into the benefits of drinking hot water.
This article looks at eight of the potential benefits and the theories behind them.
1. Healthier digestion
Hot water is said to be an easy way to improve health.
When a person does not drink enough water, the small intestine absorbs most of the water consumed through food and drinking. This causes dehydration and can make it more difficult to have a bowel movement.
Chronic dehydration can cause corresponding chronic constipation. This constipation can make bowel movements painful and may cause other problems, including hemorrhoids and bloating.
Drinking hot water helps to break down food faster than drinking cold or warm water. It reduces the risk of constipation by supporting regular bowel movements.
2. Body detoxification
Natural health advocates argue that hot water might help the body detoxify. When water is hot enough to raise a person's body temperature, it can cause sweating. Sweating expels toxins and can help clean the pores.
3. Improved circulation
Hot water is a vasodilator, meaning it expands the blood vessels, improving circulation. This can help muscles relax and reduce pain.
Although no studies have directly linked hot water to sustained improvements in circulation, even brief improvements in circulation can support better blood flow to muscles and organs.
4. Weight loss
Research has long supported the idea that drinking more water can help a person lose weight. This may partially be because drinking water increases feelings of fullness. Water also helps the body absorb nutrients, and it flushes out waste.
A study published in 2003 found that switching from drinking cold water to hot water could increase weight loss. Researchers found that drinking 500 ml of water before a meal increased metabolism by 30 percent.
Raising water temperature to 98.6 degrees accounted for 40 percent of the increase in metabolism. This metabolic step-up lasted for 30-40 minutes, following water consumption.
5. Reduced pain
Hot water improves circulation and may also improve blood flow, particularly to injured muscles. No research has directly linked hot water consumption to pain relief.
However, people routinely use heat packs and hot water bottles to reduce pain. Consuming hot water may offer some internal pain relief, but it is important to note that heat can also exacerbate swelling.
6. Fighting colds and improving sinus health
Heat applied to the sinuses can alleviate pressure caused by colds and nasal allergies. Steam also helps unclog the sinuses.
Drinking hot water may help mucous move more quickly. This means that drinking hot water may encourage coughing and nose-blowing to be more productive.
7. Encouraging consumption of coffee and tea
Hot water mixed with tea or coffee may offer some additional health benefits.
When mixed with coffee or tea, hot water may offer additional health benefits. Coffee and caffeinated teas can dehydrate the body, especially at high doses, but they also offer some health benefits in moderation.
Research published in 2017 linked coffee consumption to a longer life. Other research has found a link between moderate coffee consumption and a reduced risk of Parkinson's disease, some cancers, type 2 diabetes, some liver disease, and heart health problems.
Tea may reduce the risk of stroke, heart disease, type 2 diabetes, and liver disease. Some studies have linked tea to a reduced risk of cancer, but the results vary.
8. Reduced stress
A soothing cup of hot water may help people manage stress and anxiety. An older study found that consumption of hot liquids, such as tea and coffee, could lower stress and reduce feelings of anxiety.
The study argues that some of the effects are due to caffeine, but that the warmth also played a role in the improved mood of participants.
Risks
Drinking hot water from a covered cup may reduce the risk of being burned from a spillage.
The primary risk of drinking hot water is one of being burned. Water that feels pleasantly warm on the tip of a finger may still burn the tongue or throat. A person should avoid consuming water that is near boiling temperature, and they should always test a small sip before taking a gulp.
Drinking hot water in a covered, insulated cup can reduce the risk of spilling the water and getting burned.
Drinking caffeinated coffee or tea may cause a person to become overcaffeinated or jittery.
A person can prevent this by limiting the cups of coffee or tea they consume, or replacing caffeinated drinks with plain hot water.
The right temperature
Hot beverages, such as coffee or tea, are often served at near-boiling temperatures. It is not necessary for a person to risk a burn to gain the benefits of hot water. People who dislike hot water should consider drinking water at or slightly above body temperature.
A 2008 study reported an optimal drinking temperature of 136 °F (57.8°C) for coffee. This temperature reduced the risk of burns, but still offered the pleasant sensations of a hot drink.
Conclusion
Drinking hot water will not cure any diseases but, as long as the water is not scalding, the risks are minimal. So people who already enjoy hot water or who want to try a simple method for improving their health should feel assured that they are benefiting from it.

2) When is the best time to drink water?
The human body needs water to perform normal bodily functions. It is therefore vital for a person to drink water every day. However, there is some debate about whether people should drink water before going to bed.
In this article, we look at the benefits of drinking water, how much to drink each day, and the pros and cons of drinking water near bedtime.
Fast facts on drinking water before bed:
- Drinking enough water is vital for keeping hydrated and for general health.
- There is little evidence to suggest any specific benefits of drinking water at bedtime.
- If a person loses more water than they consume, they risk becoming dehydrated.
Water before bed: Pros and cons
If someone feels dehydrated at night or is at risk of dehydration, then they should drink some water. Beyond this, there are few specific benefits of drinking water before bed.
However, drinking water before going to bed can increase a person's risk of nocturia.
What is nocturia?
Drinking water before bed may increase the need to urinate at night.
Nocturia is the increased need to urinate at night. While asleep, the human body produces more hormones that slow down kidney function and decrease urine production.
This combination reduces the need for people to urinate during the night and helps them sleep uninterrupted. Repeatedly getting up can reduce both the duration and quality of sleep.
Risks of nocturia
When people's sleep is disturbed by nocturia, it can have a significantly impact on their quality of life.
A person's memory, concentration, and mood can be negatively affected by sleep deprivation. The risk of a range of disorders can also be increased, including obesity, heart disease, diabetes, and depression.
Nocturia can happen to anyone at any age but is more common in older people. The following can also increase the risk of nocturia:
- benign prostatic hypertrophy
- overactive bladder
- diabetes
- bladder infections
- heart disease
- constipation
- certain medications
Getting rid of nocturia
People with nocturia should avoid drinking water in the late evening. A person could try having their last glass a few hours earlier than normal.
Drinking an adequate amount of water during the day is still important. Unless the person is drinking too much, reducing total intake does not usually help.
However, close to bedtime, people should reduce or avoid:
- alcohol
- tea
- coffee
- cocoa or hot chocolate
- cola or sodas
The need to urinate is increased by caffeine and alcohol. Caffeine can also make it more difficult for someone to fall asleep.
People should see a doctor to rule out other possible underlying conditions if they are experiencing persistent nocturia.

3) How much water do people need to drink?
Sweating due to exercise or physical activity will increase the need to drink water.
A person should drink fluids whenever they feel dehydrated or if there is a high possibility of dehydration. Signs of dehydration include:
- thirst
- dry mouth, lips, nasal passages, and eyes
- passing only small amounts of urine
- urinating less than four times a day
- strong-smelling and dark-colored urine
The following things increase the risk of dehydration:
- hot environments or being in the sun too long
- intense physical activity or anything that causes excessive sweating
- diabetes
- diarrhea or vomiting
- drinking too much alcohol
- fever
According to the European Food Safety Authority (EFSA), it can be fatal if a person loses more than 10 percent of their body water.
There is no consensus on how much water people should drink each day. The Centers for Disease Control and Prevention (CDC) and the Food and Nutrition Board (FNB) say thirst alone is enough to guide most people on how much to drink.
However, the FNB suggest women should take in around 2.7 liters of water daily and men around 3.7 liters.
These amounts include the water obtained from eating, which is estimated to make up 19 to 20 percent of daily intake.
Health benefits of drinking water
Water is a cheap and effective way of quenching thirst and replacing lost fluids. As well as being essential for general health, drinking water has several other potential benefits:
- managing body weight
- improving mood and mental performance
- preventing headaches
One small study suggests that increasing daily water intake by 1.5 liters in people with migraines may reduce the headaches. However, it only showed a limited effect in preventing them altogether.
Preventing hangovers
Drinking alcohol in moderation is the most effective way to prevent a hangover, although drinking a glass of water before sleep may also help.
Alcohol increases the need to urinate. This can lead to dehydration, which causes some of the symptoms of a hangover.
The best way to avoid a hangover is to drink alcohol in moderation. However, the following tips can also help prevent or reduce the effects of a hangover:
- avoiding alcohol on an empty stomach
- having a glass of water or a non-carbonated soft drink between alcoholic beverages
- drinking a glass of water or two before sleep
Takeaway
Getting enough water is essential for health. In most healthy people, thirst is sufficient in guiding them to know how much to drink.
Water is a cheap, no-calories alternative to sugary drinks and may help improve mood and mental performance. It can also help to prevent headaches and hangovers.
However, if a person drinks water before bed, it can increase the need to urinate during the night and significantly impact on their sleep.
