While dehydration is often associated with being thirsty, that’s not the only warning sign our bodies share with us.

The condition can occur when you use or lose more fluid than you take in, which can impact the body’s ability to perform its normal functions, say experts.

The body loses fluids and water through sweating and urination, according to Cleveland Clinic.

“In warm and hot weather in particular, your body loses water and fluid faster,” Mike Sevilla, M.D., a family physician with Salem Family Care in Salem, Ohio, told Fox News Digital.

“If these fluids are not replaced, the body becomes dehydrated.”

Although anyone can become dehydrated, it can be especially dangerous for vulnerable groups, such as young children and the elderly.

5 surprising symptoms of dehydration

Doctors shared with Fox News Digital some of the signs of dehydration that go beyond thirst.

1. Sweating

It may come as a surprise that excessive sweating could be an indicator of dehydration.

“In heat and humidity, we lose more water in the form of perspiration, which is what triggers the body to tell the brain that it needs water and the actual feeling of thirst,” Lauren Fine, M.D., a board-certified dermatologist with Fine Dermatology in Chicago, told Fox News Digital.

2. Sickness

Illness is an often overlooked cause of dehydration. With excessive vomiting or diarrhea, the body can quickly become depleted of fluids — especially with younger people and older adults, Sevilla said.

“Having a fever or an infection can also lead to dehydration, because fever can cause you to sweat and thereby lose fluid,” he cautioned. 

3. Fatigue

One of the initial signs of dehydration is fatigue.

Fatigue is one of the early signs of dehydration, according to experts. (iStock)

“People usually ignore this symptom, thinking that they are just tired,” Sevilla said — but it can progress to dizziness and lightheadedness.

To combat fatigue, he recommends consuming beverages with electrolytes to boost energy levels.

4. Dark urine

If your urine is amber- or honey-colored, or dark orange, this may indicate that your body isn’t getting enough water, according to Health.com. 

      

“If you’re dehydrated and are holding onto more of the actual water itself, the urine will become darker and darker,” Michael A Palese, M.D., chair of the Department of Urology at Mount Sinai in New York, told Health.com.

5. Skin changes

Dehydrated skin can look dull and dry, and can also show premature signs of aging, such as surface wrinkles.

“Skin cells need water to survive,” said Fine.

To keep the skin hydrated, she recommends drinking water while working out, reducing intake of coffee and other caffeinated beverages, and eating more fruits, vegetables and legumes.

When to seek medical attention

The longer dehydration continues without intake of sufficient fluids, the worse the symptoms become, according to Sevilla.

Severe dehydration leads to dizziness, confusion, increased heart rate and low blood pressure, the physician said.

“The more severe the case of dehydration is, the more difficult it is for people to drink enough fluid to help the situation,” he said.

Words and game of Scrabble keep married couple in wedded bliss for decades

A married couple who have long enjoyed the game of Scrabble both together and separately before they even met are never at a loss for words — and attribute their wedded bliss in part to their love of the nostalgic game.

They’re still playing in tournaments built around the game decades after they began doing so.

Graham Harding and his wife Helen Harding, both in their 60s, have been married for over 20 years.

WATCHING GAME SHOWS LIKE ‘JEOPARDY!’ AND ‘WHEEL OF FORTUNE’ CAN BOOST COGNITIVE HEALTH, SAY EXPERTS

They met in the 1990s at Scrabble tournaments, as news agency SWNS reported.

Graham Harding is from the East Berkshire Scrabble Club, while his wife Helen is from the Leicester Scrabble Club in the U.K.

They have been taking part in the UK Open Scrabble Championship in Reading this week.

“The more words you know, the more ammunition you’ve got.”

“Scrabble is all about having a good vocabulary,” said Graham Harding, SWNS noted.

They each took up the hobby early in life well before they met each other. 

The tournament that’s been taking place this week is the first since the COVID pandemic after a five-year break — and the couple has played some two dozen games in it as of Friday, SWNS reported.

Deep sleep can keep two big health problems at bay, new studies suggest

Deep sleep can keep two big health problems at bay, new studies suggest

It might be worth working a little bit harder to get that much-desired, but often elusive, good night’s sleep.

Deep sleep clears the mind of waste just as a “dishwasher” cleans dirty plates and glasses, just-published research suggests — and there’s more.

The findings also offer insights into how sleeping pills may disrupt the “brainwashing” system — potentially affecting cognitive function for people over the long run.

ANOTHER REASON TO GET MORE SLEEP AND THIS ONE MIGHT SURPRISE YOU

Study senior author professor Maiken Nedergaard of the University of Rochester and the University of Copenhagen said norepinephrine (a neurotransmitter and hormone) triggers blood vessels to contract — generating slow pulsations that create a rhythmic flow in the surrounding fluid to carry away waste, news agency SWNS noted.

Said Nedergaard, “It’s like turning on the dishwasher before you go to bed and waking up with a clean brain. . . . We’re essentially asking what drives this process and trying to define restorative sleep based on” this “glymphatic clearance.”

The brain has a built-in waste removal process – the glymphatic system – that circulates fluid in the brain and spinal cord to clear out waste, according to the scientists. 

The process helps remove toxic proteins that form sticky plaques linked to neurological disorders, such as Alzheimer’s disease.

But the scientists indicated that what drives the system was unclear until now, according to the study.

Is all sleep created equal? The researchers wanted to find out.

To find clues, Nedergaard and her team looked into what happens in mice when their brains sleep, as SWNS reported of the study. The team focused on the relationship between norepinephrine and blood flow during deep sleep.

They found that norepinephrine waves correlate to variations in brain blood volume — suggesting that norepinephrine triggers a rhythmic pulsation in the blood vessels. The researchers then compared the changes in blood volume to brain fluid flow.

The brain fluid flow fluctuates in correspondence to blood volume changes, suggesting the vessels act as pumps to propel the surrounding brain fluid to flush out waste.

Natalie Hauglund of the University of Copenhagen and the University of Oxford, the study’s lead author, said, “You can view norepinephrine as [the] conductor of an orchestra.” 

She added, “There’s a harmony in the constriction and dilation of the arteries, which then drives the cerebrospinal fluid through the brain to remove the waste products.”  

‘I CAN’T SLEEP BECAUSE OF RACING THOUGHTS AT NIGHT — HOW CAN I STOP THEM?’: ASK A DOCTOR

Hauglund said she wanted to understand whether all sleep is created equal. 

To find out, the research team administered zolpidem, a common drug to aid sleep, to mice.

“If people aren’t getting the full benefits of sleep, they should be aware of that, so they can make informed decisions.” 

They found that the norepinephrine waves during deep sleep were 50% lower in zolpidem-treated mice than in naturally sleeping mice. 

Although the zolpidem-treated mice fell asleep more quickly — fluid transport into the brain dropped more than 30%, as SWNS reported.

Two new studies indicate the importance of getting a good night’s sleep — with one study saying a lack of sleep may be sabotaging the brain’s ability to keep intrusive thoughts at bay. (iStock)

The researchers say their findings, published in the journal Cell, suggest that the sleeping aid may disrupt the norepinephrine-driven waste clearance during sleep.

Hauglund said, “More and more people are using sleep medication, and it’s really important to know if that’s healthy sleep. If people aren’t getting the full benefits of sleep, they should be aware of that, so they can make informed decisions.”

The research team said the findings likely apply to humans, who also have a glymphatic system, although it requires further testing.

Nedergaard added, “Now we know norepinephrine is driving the cleaning of the brain, we may figure out how to get people a long and restorative sleep.”

Meanwhile, a lack of sleep may be doing more damage than just making people groggy.

Another new study, this one published in the Proceedings of the National Academy of Sciences, found that sleep deprivation weakens the brain’s defense against unwanted memories, allowing them to flood the mind, according to the New York Post. 

“We show that sleep deprivation disrupts prefrontal inhibition of memory retrieval, and that the overnight restoration of this inhibitory mechanism is associated with time spent in rapid eye movement (REM) sleep,” the scientists said.
