Neither warm nor cold water is universally "better"; they offer different benefits, with warm water aiding digestion, relieving congestion, and promoting relaxation, while cold water provides superior refreshment and helps cool the body during exercise, but the most important factor for overall health is staying hydrated, making room temperature a good everyday choice. Your body quickly adjusts water temperature anyway, so personal preference and the specific situation often dictate the best choice, say health experts.
Warm water may help dilate blood vessels slightly, which can improve circulation. Better circulation ensures that oxygen and nutrients are effectively delivered throughout the body5. Improved circulation from warm water intake can ease mild muscle and joint discomfort.
Warm water accelerates intestinal muscles, which move food easily throughout the digestive system. It also softens faeces, leading to healthier, more pleasant bowel movements. Begin every morning by drinking warm water to prepare your digestion and cleanse your system.
Staying hydrated is important for your body, and drinking water throughout the day can help you achieve that. The best temperature range for water to be absorbed and rehydrate effectively is between 10-22 degrees Celsius (50 - 72 degrees Fahrenheit).
Staying Hydrated Is What's Important
The idea that drinking warm or hot water in the morning, or at any time, is better or worse than cold water is much more myth than fact. While water itself is essential for life, the temperature matters very little from a scientific perspective.
Warm water helps soften stool (poo), allowing bowel movement to occur more easily. Plus, starting your day with a glass of warm water on an empty stomach can help keep regulated & even cleanse your gut.
Water is the drink of choice for heart health. If you're thirsty, drink water. When the weather is warm or we're exercising, our bodies need more water than usual. Unflavoured milk, tea and coffee can be enjoyed in moderation.
In Traditional Chinese Medicine (TCM), cold drinks are thought to disrupt the body's internal balance by weakening key organs like the spleen, kidney, and liver.
On the night of April 14–15, 1912, the Titanic sank into the frigid waters of the North Atlantic. Some 1,500 people perished, and for most of the victims, the cause of death was hypothermia, not drowning. The water temperature was approximately 28 ℉ (−2 ℃), which is below the freezing point of water.
Hot and warm water is just as hydrating as cold and ambient water. However, we consume both in very different ways and often for quite clearly different reasons. When we heat up our water for tea or coffee, we do so with the aim of consuming a delicious drink to wake us up, or perhaps help us drift off to sleep.
Drinking hot water can calm the mind and body, which is great before bed. Not only does it activate your nervous system and promote relaxation, but it also increases your body temperature, triggering feelings of drowsiness and making it easier for you to fall asleep.
Warm Water and Blood Pressure:
Warm water does not directly lower high blood pressure significantly. It may help with relaxation, offering a mild, temporary effect.
By drinking water when you wake up, the blood flow to your brain is improved, helping you stay more alert. Flushes out toxins – As you sleep, your body carries on working to repair and regenerate cells. A glass of water in the morning will help your kidneys flush out your body's waste and toxins more effectively.
Potential Disruption of Digestion
Warm water can generally help with digestion. But drinking it right after a big meal or too close to bedtime might weaken your stomach acids, which can actually slow your digestion. This could cause bloating, a little discomfort, or indigestion while you're trying to sleep.
Filtered Tap Water: Drink it, cook with it.
Install a reverse osmosis filter if you can afford it, to remove contaminants that carbon filters can't eliminate, like arsenic and perchlorate (rocket fuel).
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.
Three small dogs, two Pomeranians and a Pekingese, survived the Titanic disaster cradled in their owners' arms as they climbed into lifeboats.
It only took about 30 minutes for all those poor people to freeze to death in the water. There was also Cold Shock where the moment you would hit that water it would cause immediate shock and gasping breaths. Titanic disappeared at 2:20 am on April 15th leaving over 1,500 people in the water.
One of these is a species of bacteria -- named Halomonas titanicae after the great ship -- that lives inside icicle-like growths of rust, called "rusticles." These bacteria eat iron in the ship's hull and they will eventually consume the entire ship, recycling the nutrients into the ocean ecosystem.
In Europe, ice never gained the same popularity — not in the 19th century and not today. Whereas Americans look upon ice with glee, generally speaking Europeans view ice as unnecessary, and even a little gross. “I'll order iced drinks during the summer out of necessity,” says Dinhut.
These are the countries with the cleanest drinking water in the world:
In China, tap water is not filtered sufficiently to be drunk as it is not sterilized, or purified, and may carry hazardous contaminants like sediments, rusts, bacteria, virus, chlorines, or other heavy metals). This water can be purified by boiling it which is why Chinese people often take their water hot.
Drinks rich in nitric oxide-boosting compounds, such as beetroot juice, green tea, and pomegranate juice, help open blood vessels and enhance circulation. These drinks aid in stimulating blood flow, lowering systolic blood pressure, and reducing the risk of arterial stiffness.
Water is a healthy and cheap choice to keep you hydrated, but other drinks can also count towards your fluid intake. We also get some fluids from the foods we eat. Not getting enough fluids can lead to dehydration.
