Is thirst a good predictor of dehydration?

Published

on

Water is important for on a regular basis functioning and health, and we are able to only survive a few days without it. However, once we breathe, we always lose water through sweating, urination, and even evaporation.

That’s why we have evolved a solution to regulate and maintain water in our body. Like other animals, our survival relies on a strong biological drive to seek out and drink water to compensate for fluid loss.

It’s thirst – the sensation of a dry mouth that signals that we want to drink. This basic physiological mechanism it’s controlled mainly by a part of the brain’s “control center” called the hypothalamus. Hypothalamus receives signals from various parts of the body and in return releases hormones that act as a transmitter signaling the sensation of thirst.

What is dehydration?

Staying hydrated (having enough water in your body) is significant several reasonsincluding:

  • regulation of body temperature through sweat and respiration
  • lubrication of joints and eyes
  • infection prevention
  • digestion and absorption of nutrients
  • flushing out waste (via the kidneys)
  • stopping constipation
  • brain functioning (including memory and concentration)
  • mood and energy levels
  • physical fitness and regeneration after physical exertion
  • skin health.

Dehydration occurs when there just isn’t enough water in our body. Even slight drops in fluid level occur noticeable consequencesresembling headaches, dizziness, lethargy and trouble concentrating.

Chronic dehydration it could possibly cause more serious health risks, including urinary tract infections, constipation and kidney stones.

What does the evidence say?

Although thirst is one of probably the most basic biological aspects that determine good hydration, science suggests that our feelings of thirst and subsequent fluid intake don’t at all times correlate with our hydration levels.

For example: recent research examined the impact of thirst on fluid intake and hydration status. Participants participated in laboratory testing within the morning after which later within the afternoon to offer indicators of hydration status (resembling urine, blood samples, and body weight). The relationship between the extent of thirst within the morning and the extent of hydration within the afternoon was negligible.

Additionally, thirst could also be attributable to environmental aspects resembling access to water. For example, one study tested whether abundant access to water within the laboratory affects how much people drink and the way hydrated they’re. The association between thirst and hydration levels was weak, suggesting that water availability had a greater impact on fluid intake than thirst.

Exercise can too change the mechanism of desirealthough research is proscribed at this stage.

Just because we’re thirsty doesn’t necessarily mean we’re dehydrated.

Interestingly, research shows that ladies feel thirsty more strongly than men, regardless of their hydration status. Understand gender differences in desireresearchers gave men and girls fluids after which measured their thirst and hydration status. They found that ladies generally reported thirst with lower levels of fluid loss. Women have also been found to react more often to the sensation of thirst drinking more water.

Other ways to inform if it is advisable to drink water

While it’s clear that some people might want to drink kind of, for many individuals, eight cups (or two liters) a day is the precise amount of water to aim for.

But beyond thirst, there are numerous other ways to inform if it is advisable to drink more water.

1. urine color: pale yellow urine normally indicates good hydration, while darker, concentrated urine suggests dehydration

2. frequency of going to the bathroom: regular urination (about 4 to 6 times a day) indicates good hydration. Infrequent urination may signal dehydration

3. skin turgor test: gently skin pinching (for instance, on the back of the hand) and observing how quickly the skin returns to its normal position will help assess hydration. Slow recovery may indicate dehydration

4. lips and lips: dry mouth or cracked lips will be early signs of dehydration

5. Headaches and Fatigue: chances are you’ll experience frequent headaches, dizziness or unexplained tiredness signs of insufficient hydration

6. sweating: in physically lively people, monitoring the quantity of sweating during activity will help estimate fluid loss and hydration needs. Higher sweat levels may predispose a person to dehydration in the event that they are unable to exchange fluids lost through water consumption

When used together, these indicators provide a more complete picture of hydration without relying solely on the sensation of thirst.

Of course, when you feel thirsty, it’s still a good idea to drink water.

The intersection of hair and culture inspired Meji Meji’s latest top, Essence

Meji Meiji designer Tolu OyeGrowing up, her relationship together with her hair was, in her words, “turbulent.” Ultimately, nonetheless, this was reconciled with acceptance and appreciation of her culture. Born in Lagos, Nigeria and raised in Ohio, Oye has heard mixed opinions about beauty standards for so long as she will be able to remember. Ultimately, in a city where diversity was rare, it was as much as her to make a decision what she desired to imagine.

The intersection of hair and culture inspired the latest Meji Meji top

“At some point I went through a relaxation phase. I didn’t want anything that was symbolic of me as an African. I think 2016 was a major change for me. I went to Nigeria again and in a sense I was reborn in terms of my love for my culture,” she tells ESSENCE. “Now, if I can spread the gospel of different elements of my culture in any way, even through hair, I want to use it as a form of storytelling.”

Her clothing brand Meji Meji, launched in 2020, is actually an example of this. One of her bestsellers, the Na Me Cause Am t-shirt, incorporates a black femme fatale with an afro within the primary role. And now? Her recent one Sisi Ologe top is an element of this tradition that not only embraces her relationship with hair, but in addition uplifts and preserves her culture.

The top embodies the photographs you would possibly see when flipping through a Seventies newspaper wig campaign ad: from the voluminous blowout and kinky coils to the intricately braided hairstyles that reflect the expansiveness of African beauty. Collaborating with artists on her work is amazingly essential to her since it allows her to be the voice of Africa. This time she selected an artist specifically Joseph Edgar. It took six months to perfect the print itself – it was an actual labor of love.

Meanwhile, the campaign imagery is reminiscent of Nollywood movies – combining nostalgia with contemporary Shuku updos. All this was achieved because of her long-time friends and collaborators, The law of jokes AND Opeyemi Oyebanji. Their hairdressing skills brought the designer’s campaign to life with intricate updos that highlighted the complexity of the highest

But the world of hair has all the time appealed to Oye’s soul long before she became the founder of the brand. At age 5, she called the basketry salon where her mother worked “her after-school program.” There, she helped her mother finish the ends of braids on her clients’ hair, and watching Nollywood movies ignited her love for fashion and beauty.

“I recently asked my mom if I was addicted to toys growing up, and she said, ‘Not at all, but you were.’ You sat in front of the TV and watched the transformations over and over again. Then I noticed your interest in hairstyles and fashion. She wasn’t surprised when I started taking on my own clients from school,” Oye says.

She was influenced by how hairstyle and fashion can improve someone’s self-confidence. She knew that design was her calling, but it surely was also crucial for her clothes to be connected to her roots – her history as an African woman – and to include her personal love of preserving African braiding techniques.

“I am grateful to my parents for nurturing my talent, which led to me moving to New York at the age of 15,” where she attended Art & Design School. “It took years to become a muse” – because of her signature look, which included braids with bangs, freestyle braids, twisted mohawks and more. “I was giving hairdressers headaches because they were saying, ‘That girl and her crazy hairstyles are back.'” That was until she found her tribe with Helena Koudou AND Lawal’s joke– who were equally excited to create hair magic together with her.

In 2018, Oye got here up with a hairstyle titled Suspicion + Periwinkle. It featured a tall cone pinned up with three rows of curled braids in front as bangs. This style was in all places, from the CFDA red carpet to Jameson’s packaging to the Burna Boy music video. “Seeing people’s reactions to this style around the world made me realize it’s not just about the hair,” she says. And like those iconic moments, Oye understands how essential it’s to have that representation in the whole lot he does. As he explains, “it’s about maintaining traditional techniques while adding a modern twist. This is my legacy.”

Are Colonics really good for the skin? – Essence

Published

They say it’s higher to depart than to enter? At least that appears to be the general consensus amongst the who’s who of the wellness community – where colon health is all the rage. If you are not aware of the science of colon therapy – also generally known as colon therapy, colonic hydrotherapy, and colonic irrigation – colonics describes the strategy of flushing out the intestines with a considerable amount of fluid.

On social media, influencers and personalities are sharing très chic selfies and boomerangs in luxurious spa-like settings, documenting their intestinal processes as if it were a daily visit to a beauty salon.

How did we get to the point where intestinal hydration is touted in the same wellness wheelhouse as hydromassage and sugaring? Where else but TikTok, where else “hot girls” have stomach problemsIBS is sexy and “gut health” is all you’ll be able to discuss?

As such, the feeling of “emptying” your insides has develop into as desirable as a pair of Margiela Tabis or enchanted Coach bags. From MiraLax Julius smoothies to digestive lymphatic massages, gut tricks are regular menu options at the bustling online gut discourse restaurant.

However, in the colon school of digestive discourse, they’re the humble, cool kid on the block. And like all really cool kids, the colon is shrouded in an air of palpable mysticism. But don’t be concerned, because from the root to the trumpet, we have got you covered with every thing it’s essential to find out about the colon.

What is the large intestine?

“When people discuss colon treatment, they are often talking a few practice also generally known as colon hydrotherapy or colon cleansing; “This involves inserting a tube into the anus to flush the large intestine, or colon, in order to get rid of the feces accumulating in the colon,” he explains. Zofia Balzora board-certified gastroenterologist and professor of clinical medicine at New York University.

“Colon cleansing may also involve the process of removing feces/stool from the colon using medications administered rectally (enema) or orally,” explains Dr. Balzora.

Many individuals who use colon therapy say they do it for the waste-removal advantages, touting the fat-removing effects, but based on Dr. Balzora, our bodies do a reasonably good job of keeping us in check without tubes.

“There is a misconception that we’d like to assist our body detoxify. Or help ‘boost’ our immune system or make it simpler,” says Dr. Balzora.

our bodies are literally very effective at absorbing what we’d like from food and eliminating excess toxins and waste.

“The function of the colon, or large intestine, is to manage water absorption and hold stool until it’s able to be passed. This is a traditional process occurring in the large intestine and doesn’t require cleansing assistance, which just isn’t supported by clinical evidence and will even be dangerous,” explains Dr. Balzora.

Is the colon good for the skin?

Our skin can tell us loads about our health. As our largest organ, it largely reflects what is occurring inside us. From liver disease to skin cancer, many conditions can manifest themselves through our skin. However, colonic “detoxification” has no proven skin improvement advantages because constipation doesn’t affect our skin generally.

There are some stomach problems which will manifest externally, like the rash related to celiac disease, but treating the colon just isn’t a treatment for the disease. We all want glowing skin, but colon medications don’t have any proven advantages for the appearance of our skin beyond temporary relief from bloating, which is a brief-term side effect and never price the effort. numerous threats which can accompany colon.

What is the risk?

Chronic constipation is getting quite a lot of attention on TikTok, and while an open dialogue about our health is great for destigmatizing previously taboo issues, it also opens the door to misinformation about what we needs to be putting in or taking out of our bodies.

“Colonectomy is not a medically necessary process and has no clinical or health benefits, but it can certainly cause harm,” explains Dr. Balzora.

To be clear, there are some rare medical cases where colon cleansing is crucial, comparable to before a colonoscopy. However, the protocol for these treatments is a thoroughly researched process, conducted under the supervision of a physician.

“Colon cleansing while waiting for medically indicated or necessary procedures is safe – the medications used (oral laxatives, suppositories and enemas, which have been rigorously researched and tested for safety) have a specific purpose under the supervision of a health care professional,” he says Dr. Balzor.

However, “detoxifying” the body through the colon is a dangerous endeavor.

“What is used [in detoxes] for cleansing the colon may contain substances which are rough or harmful to the colon mucosa,” says Dr. Balzora.

And (sorry to be sensitive), but there may be also a risk of perforations and tears in the intestinal lining, in addition to potentially life-threatening infections that may occur if the feeding tubes will not be properly cleaned. To summarize, no flat stomach is price your life.

The best alternatives for the colon?

So if a spa-style colon treatment is not what it’s cracked as much as be?

“If you’re concerned about constipation or have trouble going to the bathroom regularly, talk to your healthcare provider about safe and clinically proven alternatives, such as fiber supplementation or a diet high in fiber-containing foods,” says Dr. Balzora.

Additionally, an lively lifestyle can do wonders for improving your regularity. Maybe these viral clubs are on to something in spite of everything!

“Moving your body while exercising can also be an amazing and healthy option to get your intestines working. A rest room stool that sits flush against the toilet, providing a more natural angle for the anus and rectum, making it easier to pass stools for those affected by constipation, can work wonders for some, says Dr. Balzora.

When all of it comes right down to it relating to recent, exciting health routines and habits, there are still loads of gadget-powered practices you’ll be able to try without disturbing your internal organs.

how doctors use light to diagnose diseases

Published

By


You do not feel well. You’ve had a throbbing headache, dizziness, and vomiting all week after your previous few meals.

You visit your GP to get answers and sit as he shines a light in your eyes, orders a blood test and asks for imaging tests.

Everything your GP has done relies on light. These are only a number of the optical technologies which might be having a huge effect on the best way we diagnose diseases.

1. On-site testing

Point-of-care diagnostics allow doctors to test patients on-site and get answers in minutes, slightly than sending samples to a lab for evaluation.

A “flashlight” utilized by a family doctor to look contained in the eye (so-called ophthalmoscope) is an excellent example. This allows doctors to detect abnormal blood flow in the attention, deformation of the cornea (the outermost transparent layer of the attention), or swelling of the optic discs (the circular section in the back of the attention where the nerve connection to the brain begins). Swollen discs are an indication of increased pressure inside the top (or, within the worst case scenario, a brain tumor) which may be attributable to causing your headaches.

Invention lasers and LEDs has made many other miniaturized technologies available on the bedside or within the clinic, slightly than within the laboratory.

A famous example is pulse oximetry, during which a clip attached to the finger provides information concerning the level of blood oxygenation. He does this through measuring different reactions of oxygenated and deoxygenated blood to different colours of light.

Pulse oximetry is utilized in hospitals (and sometimes at home) to monitor the health of the respiratory system and heart. In hospitals, additionally it is a precious detection tool heart defects in infants.

See that clip on the patient’s finger? It is a pulse oximeter that monitors the condition of the respiratory system and heart using light.

2. Looking at molecules

Now let’s return to this blood test. Analyzing a small amount of blood allows you to diagnose many various diseases.

A tool called an automatic “complete blood count analyzer” that checks overall health indicators. This device directs focused beams of light through blood samples stored in small glass tubes. It counts the variety of blood cells, determines their specific type and provides the extent of hemoglobin (a protein in red blood cells that distributes oxygen within the body). Within minutes this machine can deliver snapshot general health.

To obtain more specific disease markers, blood serum is separated from heavier cells by centrifugation in a rotating instrument called a centrifuge. The serum is then subjected to special chemical stains and enzyme tests that change color depending on the presence of certain molecules, which could also be an indication of disease.

These color changes can’t be detected with the naked eye. However, a beam of light from an instrument called a spectrometer can detect small amounts of those substances within the blood and determine whether and at what concentrations biomarkers of diseases are present.

3. Medical imaging

Let’s look again on the medical images ordered by your GP. The development of fiber optic technology, which became famous for transforming high-speed digital communications (comparable to NBN), allows light to enter the body. Result? High resolution optical imaging.

A typical example is endoscopeduring which fibers with a small camera on the top are inserted into natural body openings (comparable to the mouth or anus) to examine the intestines or respiratory tract.

Surgeons can use the identical technology through tiny incisions to view the within the body on a video screen during surgery laparoscopic surgery (also generally known as keyhole surgery) to diagnose and treat diseases.

What concerning the future?

Advances in nanotechnology and a greater understanding of how light interacts with our tissues are leading to latest light-based tools that help diagnose disease. These include:

  • nanomaterials (materials on a particularly small scale, many 1000’s of times smaller than the width of a human hair). They are utilized in next-generation sensors and latest diagnostic tests

  • wearable optical biosensors nail size will be taken into consideration in devices comparable to watches, contact lenses and finger bands. These devices enable non-invasive measurement of sweat, tears and saliva in real time

  • AI tools to analyze how blood serum scatters infrared light. This enabled scientists to construct extensive database scatter patterns to detect any cancer

  • a kind of non-invasive imaging, the so-called optical coherence tomography for more detailed imaging of the attention, heart and skin

  • fiber optic technology that enables a small microscope to be introduced into the body the tip of the needle.

So the following time you see your primary care doctor who performs (or orders) certain tests, chances are high that a minimum of certainly one of those tests will depend upon light to diagnose the disease.
