Water dethroned: these 5 drinks hydrate even better, according to science

Water: vital, yes — but not unbeatable

Let’s get one thing straight: no one is denying how essential water is. Nearly all living things depend on it to function and survive — it’s the foundation of life itself. Still, when we look at the facts, is it really the drink that hydrates us best?

It seems obvious that the answer would be yes. If you’re thirsty, drink water — problem solved, right? Not so fast. Chemically speaking, the story is a little more complex. The formula H₂O refers to distilled water, not the kind we actually drink. Tap and bottled waters contain trace minerals like calcium, magnesium, and potassium — which, as it turns out, make a big difference.

Our bodies are accustomed to mineral water, but drinking distilled water over time can upset our balance of electrolytes — the charged minerals that regulate chemical reactions, nerve function, and fluid balance. That’s why the drinks that hydrate best are those rich in electrolytes.

You might think first of an oral rehydration solution — those powdered mixes often given to babies after a bout of gastroenteritis. They’re designed to replace lost water, salts, and nutrients, helping the body recover its balance quickly.

The top five most hydrating drinks

With an endless array of beverages — from fruit juices to sports drinks to sodas — it’s hard to tell which ones actually hydrate best. Since hydration power isn’t listed on labels, researchers at the University of St. Andrews decided to test it scientifically.

They evaluated how quickly different drinks hydrate the body and how long the effect lasts. The key discovery? Drinks that contain small amounts of lactose, protein, or fat help the body retain fluids longer — because these components slow down how fast water exits the system.

The results were surprising. Skim milk ranked first, with a Beverage Hydration Index (BHI) of 99%, tying with oral rehydration solutions and whole milk. Orange juice came next, with a BHI of 95%, just edging out water itself.

Here’s the ranking:

  1. Skimmed milk
  2. Oral rehydration solution (for children, athletes, or seniors)
  3. Whole milk
  4. Orange juice
  5. Water

Yes, plain water only comes fifth — though researchers caution that the hydration differences are minor. This doesn’t mean you should start swapping water for milk every day. But for groups like older adults, infants, or people who struggle to drink large amounts of liquid, these alternatives might provide better hydration support.

In short: water is still life’s essential liquid — but when it comes to sheer hydration, science says it might not always be number one.

10 Warning Signs of Bladder Cancer to Watch Out For

Bladder cancer is the ninth most common cancer in the world, with the highest rates being in North America and Europe. This is why you need to pay attention to all possible signs and symptoms so that you can detect it before it is too late. Here's what you need to pay attention to:
 
1. Blood in Your Urine  
Bloody pee is the primary sign of bladder cancer. Urine color may range from pink to red to dark brown, and you often won't be able to see it with the naked eye. Blood in your urine may also mean you have a bladder infection, UTI or even kidney stones.

2. Pelvic Pain  10 Warning Signs of Bladder Cancer to Watch Out For
 
If a malign tumor grows within your bladder wall, pressure or pain may be present. Make sure to tell your doctor about ongoing pelvic pain or a strange feeling of pressure, particularly if it’s accompanied by any other symptoms.

3. Frequent Urination  
Having to get up to pee all the time could be a sign of an infection. However, it could also indicate that bladder cancer is developing inside of you. 
 
4. Swollen Feet 
Swelling in the ankles or feet is a sign that bladder cancer may have advanced and metastasized to other parts of your body. What's more, swollen feet may also be a symptom of either bladder or kidney cancer. 
 
5. Loss of Appetite or Weight 
Common with many cancers, a loss of weight or appetite may mean that cancer cells have formed inside of you. Sudden and unexplainable changes in your eating habits or weight should be a red flag, so make sure to visit a physician as soon as possible.

6. Feeling Weak or Fatigued 
Bladder cancer may lead to fluid accumulating in your body, which in turn can make you feel lethargic, which is why you should visit a doctor if you're feeling tired for no apparent reason. 
 
7. Unable to Pass Urine 
A blockage in your urinary tract might be preventing your bladder from passing urine. If this is the case for you, you should get examined to determine if it’s being caused by a tumorous growth, cyst, kidney stone or some other condition.


8. Feeling of Having to Pee 
What this means is that even though your bladder is empty, you still often feel an urgent need to pee. If this keeps happening to you on a regular basis, visit a health professional. 
 
9. Burning or Pain During Urination 
A painful, burning sensation during urination is linked to many types of illnesses, so you should never just wait for this symptom to disappear of its own accord. In fact, this symptom is present in 3 different kinds of cancers – bladder, kidney, and prostate. 
 
10. Back Pain 
Back pain may be a sign that bladder cancer has entered a more advanced stage, but it may also indicate that you have a kidney infection or some other urological condition, so you should visit a doctor as soon as possible.

How Garlic Keeps Your Blood Sugar and Cholesterol Low

Adding some garlic to your diet has been found to lower blood sugar and cholesterol levels. A new meta-analysis, a research approach that combines data from many studies, revealed favorable findings on garlic intake. 

Researchers from Southeast University and Xizang Minzu University in China examined 22 previous studies, which included 29 randomized controlled trials. Their findings suggest that frequent garlic consumption may be linked to lower blood sugar levels and lower amounts of certain cholesterol types.

Blood sugar and blood lipids, primarily glucose and cholesterol, are essential elements for human health. Glucose is the body's major source of energy, whereas lipids are the building blocks for cell membranes and hormones. However, modern dietary habits can contribute to an imbalance in these essential components, leading to an increased risk of various health issues. Furthermore, lifestyle choices other than diet can significantly affect blood sugar and cholesterol levels, such as alcohol consumption and exercise patterns.

Glucose and lipid metabolisms are meticulously controlled in healthy individuals, as noted by the researchers in their published paper. "Disorders of glucose and lipid metabolism can lead to a number of chronic diseases, including atherosclerosis, diabetes and fatty liver disease," they add. 
 
Garlic has a long history of being associated with good health. Previous research, albeit conducted in isolation, suggested that it may have a role in regulating blood lipids and glucose levels. This new study builds upon this existing body of evidence. 
 
Analysis of the cumulative studies validated the benefits of garlic consumption. Individuals who incorporated garlic into their diet had significantly lower blood glucose levels, indicating better long-term control. They also saw an increase in HDL (good) cholesterol, a drop in LDL (dangerous) cholesterol, and a reduction in total cholesterol levels.

Interestingly, triglyceride levels did not appear to be considerably affected. However, it is important to acknowledge that the current evidence cannot conclusively prove a cause-and-effect connection. In other words, we can't say for certain that eating more garlic lowers the risk of heart disease. 
 
However, the association strongly suggests that including garlic in our diets might be a delicious way to manage glucose and cholesterol levels. Further research with more focused studies is needed to explain the precise mechanisms at play. The studies included in the meta-analysis used various types of garlic, such as fresh cloves, aged extracts, and powdered pills, with durations ranging from three weeks to a year.

"The results showed that garlic has a beneficial effect on blood glucose and blood lipid in humans, and their association was statistically significant," write the researchers. The association between garlic consumption and improved cardiovascular health and blood sugar control is believed to be a result of the combined action of various active ingredients present in garlic. One important role is to reduce oxidative stress, which causes cellular damage and can lead to conditions such as cardiovascular disease. 

Garlic also contains alliin, an antioxidant molecule associated with blood glucose, blood lipids, and the gut flora. The combined impact of these processes is likely responsible for the favorable results seen in the study. 

The importance of diet in influencing health outcomes, both positive and negative, is undeniable. This new study provides further reasons to incorporate garlic into our diets. 
 
“[The study] provides new ideas for the development of natural products against diseases related to glycolipid metabolism,” write the researchers. 
 
The research has been published in Nutrients.

Health Experts Say These Teas Can Help You Live Longer

For centuries, people have turned to tea not just for its comforting warmth and delightful flavors but also for its potential health benefits. As science continues to unravel the secrets of longevity, it's becoming increasingly clear that certain teas can play a significant role in helping us live longer, healthier lives. 
 
From classic varieties like black and green tea to lesser-known gems like oolong and hibiscus, these seven teas have been scientifically proven to support longevity in various ways. This isn't about chasing a magic bullet, but rather understanding the potent compounds within these simple leaves and flowers, and how they can contribute to overall well-being. 
 
So, grab your favorite mug, and let's explore seven teas that not only please the palate but may also add years to your life. 
 
1. Oolong Tea
Healthy Teas
Oolong tea,  a traditional Chinese favorite, bridges the gap between black and green teas. It’s derived from the same plant as its counterparts but is processed differently, resulting in a unique flavor profile and a range of health benefits. Oolong tea contains a compound called EGCG, which is thought to have anti-cancer properties. 
 
Research has suggested a strong link between oolong tea consumption and a reduced risk of ovarian cancer. A study comparing tea-drinking habits revealed that regular oolong tea drinkers had a 71% lower risk of developing the disease. While more studies are needed, these findings are promising.
 
Oolong tea is widely available and doesn’t require a trip to specialty stores. Pour water heated to 190-200°F over oolong tea leaves and let it sit for 3-5 minutes. Enjoy the complex, floral notes of this semi-oxidized tea without additives for the best experience. 
 
2. Turmeric Tea
Healthy Teas
Known for its vibrant color and earthy flavor, turmeric tea is celebrated for its potential to support longevity. The health benefits of turmeric stem largely from curcumin, a powerful compound with anti-inflammatory and antioxidant properties. 
 
Studies suggest curcumin may play a role in reducing the risk of certain cancers and other chronic diseases. Health professionals have noted that turmeric’s bioactive compounds can help combat oxidative stress, a key factor in aging and disease. 
 
Simmer fresh or powdered turmeric with water, and optionally, other spices like ginger and black pepper for enhanced benefits. Strain, then sweeten with honey or maple syrup and add a splash of milk (dairy or non-dairy) for a creamy, golden latte. 
 
3. Black Tea
A staple in many households, black tea offers more than just a morning pick-me-up. Rich in antioxidants, black tea has been linked to improved heart health and reduced risks of cardiovascular diseases. 
 
Studies have found that drinking three or more cups of black tea daily may lower the risk of heart disease and stroke. One study even indicated a 9–13% reduction in overall mortality rates among regular black tea drinkers. 
 
Infuse black tea leaves in freshly boiled water for 3-5 minutes, controlling strength by brewing time. Savor its bold flavor neat, or customize with milk and sugar, a slice of lemon, or warming spices. 
 
4. Green Tea
Healthy Teas
Green tea is often hailed as a superfood in beverage form, packed with antioxidants that support a range of health benefits. It has been shown to reduce the risk of cardiovascular disease and promote brain function. 
 
Japanese studies have highlighted how drinking at least two cups of green tea daily may lower the risk of heart-related deaths by up to 33%. Matcha, a powdered form of green tea, offers even greater benefits due to its high concentration of catechins, which combat inflammation and oxidative stress. 
 
Use water heated to about 160-180°F and steep high-quality green tea leaves for 2-3 minutes. Enjoy the grassy, refreshing flavor without milk or sugar to preserve its natural taste and health benefits.
 
5. White tea
 White tea, known for its delicate flavor, is one of the least processed teas available, preserving its natural antioxidants. It has been praised for its ability to support healthy skin, boost the immune system, and promote weight management. 
 
Research indicates that white tea’s catechins can help boost metabolism, making it a beneficial choice for maintaining a healthy weight. Additionally, its anti-aging properties may contribute to skin health, keeping your complexion youthful.

Gently steep white tea leaves in hot, but not boiling, water (around 175°F) for a short period to avoid bitterness. Enjoy its delicate, sweet flavor and subtle aroma unadulterated, or with a touch of honey if desired. 
 
6. Hibiscus Tea
Healthy Teas 
Hibiscus tea stands out with its tangy flavor and vibrant red color. Beyond its taste, it may support heart health and lower blood pressure, which are both critical for longevity. 
 
Studies have shown that regular consumption of hibiscus tea can significantly reduce blood pressure levels in prehypertensive and mildly hypertensive individuals. Its natural compounds are also believed to help manage cholesterol and triglyceride levels. 
 
Steep dried hibiscus flowers in hot water for a vibrant, tart tea, then sweeten to taste and enjoy either hot or chilled over ice. Adding a slice of citrus or a sprig of mint enhances the flavor further!
 
7. Chamomile Tea
Healthy Teas
Chamomile tea is often associated with relaxation, but its benefits go far beyond calming the mind. This herbal tea has been linked to a lower risk of mortality, particularly among older women. 
 
 A study found that women over 65 who drank chamomile tea had a 29% lower risk of death from various causes. Chamomile’s anti-inflammatory properties may also help protect against heart disease, age-related bone loss, and even certain types of cancer. 
 
Let dried chamomile flowers release their calming essence in hot water for a soothing, apple-like infusion. Enjoy this naturally sweet, caffeine-free tea before bed, optionally with a drizzle of honey for extra comfort.
