Drinking hot water, coffee, teas_Benefits and risks

Drinking enough water can support skin, muscle, and joint health. Water helps the body’s cells absorb nutrients and fight infections. Drinking a few glasses of warm or hot water each day might offer even more benefits.

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.

While drinking water of any temperature can support overall wellbeing, 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

ResearchTrusted Source 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 2003Trusted Source 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 2017Trusted Source 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.

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 studyTrusted Source 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 benefitting from it.

As more people adopt this health strategy, more research may become available.

Air Canada has published a 100-page  Notice of Annual Shareholders  document detailing compensation for the company’s executives. The company received funding from the government, and part of the clause involved restrictions on executives’ pay. With those restrictions now gone, executives saw pay rises of over 100%. According to the document, in 2021, Rousseau was paid $3,717,000 in share-based awards, option-based awards, annual incentive plans, and pension value. Following the retirement of his predecessor, Calin Rovinescu, two years ago, Rousseau took the helm as Air Canada’s chief executive officer in February 2021. This year’s numbers mean Rousseau earned $6,000 per hour and received a monthly payment of...

Garlic mustard identification and control

Image
  Alliaria petiolata Garlic mustard, a Class A noxious weed, is a biennial or winter annual herb that generally grows 2-3 (up to 6) feet tall. Lower leaves are kidney-shaped with scalloped edges. Leaves feel hairless, and the root has an "S" or "L" shape just below the stem base. In spring, roots and new leaves smell like garlic, and small, four-petal white flowers appear clustered at stem ends, followed by long, skinny seedpods. This weed spreads by seed and can self-pollinate, helping it rapidly displace native plants along trails, in forests, and on riverbanks, among other areas. History and impacts Introduced from Europe originally as a food plant, this species is now a serious concern in forests across North America. Garlic mustard is an invasive non-native biennial herb that spreads by seed. Although edible for people, it is not eaten by local wildlife or insects. It is difficult to control once it has reached a site; it can cross-pollinate or self-pollinate, ...

In this article, I’m going to share some tips on saving your dill seeds for future planting and how you can also add them to your spice rack for cooking. Waiting for dill seeds to form Once your dill plants start to flower, they will attract a TON of beneficial insects to the garden. My plants are always abuzz with bees and other beneficial insects. Ladybugs,  tachinid flies , green lacewings, and hoverflies, which help to control aphid populations, all love dill flowers. The flowers stick around for a while and take some time to mature, so you need to be patient while the seeds...
