Dehydration

High Salt Intake and Dehydration Can Hasten Aging

Staying hydrated may slow the aging process. NIH researchers followed 11,255 adults for 30 years and found that compared to those who didn’t drink enough fluids, those who stayed well-hydrated:
• aged more slowly,
• lived longer, and
• were far less likely to develop chronic diseases such as those of the heart, lungs and kidneys (EbioMedicine, January 02, 2023). These findings were first presented August 27, 2021, at the European Society of Cardiology Congress.

How Not Drinking Enough Fluids May Shorten Your Life
Studies in mice found that lifelong water restriction increased the blood sodium levels by five millimoles per liter and shortened their life spans by six months, which equals about 15 years in humans (JCI Insight, Sept 5, 2019;4(17):PMC6777918). Not drinking enough fluids can raise your blood levels of sodium salt that raises blood pressure to increase risk for arterial damage.

Blood levels of sodium can be used as an indicator of levels of hydration or dehydration. All of the people in the NIH study had “normal American blood levels of sodium” from 135 to 146 millimoles per liter. So the researchers looked at those on the high end of “normal” (above 143) and found that they had a 20 percent increased risk of premature death than people with sodium levels below 144. Those with sodium levels of 145-146 were 50 percent more likely to show signs of physical aging. Those who had blood sodium levels between 142 to 143 were also at increased risk for high blood pressure, high cholesterol, high blood sugar, heart failure, stroke, chronic lung disease, diabetes and dementia.

Precaution on These Findings
This study does not prove that drinking more water prevents chronic disease. It is more likely that the people with high normal blood levels of sodium have much higher sodium levels when they are stressed, such as during exercise or exposure to hot weather, and therefore are being damaged by normal body stresses that would not have damaged them otherwise. Severe dehydration can also cause kidney damage.

How Much Water Should You Drink?
The CDC says that the average U.S. adult drinks more than five cups of fluid a day. No solid research supports the often-recommended “drink eight glasses of water a day.” The National Academies of Medicine recommend six to nine cups of fluid per day for women and eight to 12 for men, but this also is not supported by good research because fluid requirements vary tremendously depending on the person and the conditions. You get 27-36 percent of your intake of fluids from the food that you eat, and low fluid drinkers do not compensate by eating more water-rich foods (Nutrients, Oct 14, 2016 Oct;8(10):630). I believe that you should drink when you are thirsty and have at least a glass of fluid with each meal, and then probably some more several times during the day. If you have any health problems, you should check with your doctor for recommended fluid intake.

Problems From a High-Salt Diet?
A high-salt diet increases risk for high blood pressure, heart attacks, strokes and premature death (Kidney Int Suppl, Dec 2013;3(4):312-315). High blood pressure affects 108 million adults, increasing risk for heart attacks, the leading cause of death in the United States. Low-salt, plant-based diets dramatically lower both high blood pressure and markers of heart muscle damage in just four weeks (J Am Coll Cardiol, Jun 2021;77(21):2625-2634). In one study, salt restriction lowered systolic blood pressure by less than 5 mm Hg and diastolic blood pressure by only 2.5 mm Hg (JAMA Intern Med, 2014;174(4):516-524). However, the subjects in that study were already on a high-plant diet which, by itself, can lower high blood pressure because plants contain potassium and a high-potassium diet can counter some of the harmful effects of taking in too much salt (JAMA Pediatr, June 2015;169(6):560-568). You should be on a high plant, low-processed food diet that restricts meat. A review of 85 studies, following participants for up to three years, found that low-salt diets were associated with significantly lowered blood pressure (Circulation, Feb 15, 2021).

My Recommendations
Chronic dehydration can damage your cells and appears to increase risk for premature aging. Dehydration and the typical high-salt North American diet increase blood pressure risk to increase risk for heart attacks, strokes, kidney and other organ damage and premature death. I recommend that you:
• Drink a glass of water with every meal, and more fluids throughout the day or whenever you are thirsty.
• Eat lots of vegetables. They contain potassium which will counter the effects of taking in too much salt.
• Restrict processed foods that often contain added salt; check the labels.

The healthful low salt, high-potassium diet I recommend includes (per day):
• Up to 8 servings (1/2 cup cooked or equivlent) of whole grains
• At least 5 vegetables
• At least 5 fruits
• Up to 3 servings of plain yogurt or cheese (optional)
• 2 servings of seafood per week (I recommend that you avoid meat from mammals)
• Beans or legumes (no limit)
• A few handfuls of unsalted nuts or snack seeds
• A few tablespoons of olive oil (optional)

Many cases of high blood pressure can be controlled with a high-plant, low-salt diet and other lifestyle changes that include:
• trying to exercise every day
• maintaining a healthful weight
• avoiding alcohol
• avoiding smoking and second hand smoke
• keeping blood levels of hydroxy vitamin D above 30 ng/mL

4 Signs You’re Dangerously Dehydrated During Your Workout

Dehydration can sneak up on you. Here’s how to tell if you need to drink up.

 

I was rollerblading (yes, rollerblading, don’t judge) around the neighborhood I was visiting—just cruising around, nothing crazy, so I didn’t bring any water with me.

dehydration

About an hour in, I suddenly felt dizzy. I sat down under a tree in the shade for 15 minutes to get my bearings, then rolled home to enjoy a long stretch of A/C and sweet tea.

I’ve since had some scary episodes during long bike rides, but the fact is you don’t have to be pushing hard or going long to succumb to dehydration.

“It’s normal to experience mild dehydration during exercise,” says Rob Pickels, physiology director at CU Sports Medicine and Performance Center in Boulder, Colorado—especially if you’re in the heat and sweating.

“However, prolonged moderate dehydration or severe dehydration can be detrimental to your health; especially your kidney function,” he says.

You already know you need water when you feel thirsty, but there are less obvious signs that you’re on your way to serious dehydration. Here’s what Pickels warns to watch for.

A faster heart rate can be a sign of dehydration

Heart rate goes up with intensity, and it will tend to drift with long exercise (especially in the heat). However, if you’re seeing heart rates that are 15 to 20 beats higher than you’d expect, it could be your heart is compensating for reduced blood volume (aka dehydration) by beating faster.

Dizziness can be a sign of dehydration

You know how your head swims a bit when you suddenly stand from a sitting position? It’s called postural hypotension, and it’s the result of blood not reaching your head quickly enough as you change positions, thanks to low blood volume.

If you start feeling that at the gym when switching from seated to standing workouts, it could be a sign of dehydration.

Saggy skin can be a sign of dehydration

Technically called “decreased skin turgor,” when the skin on the back of your hand doesn’t snap back from being pinched, it’s a sign you need more fluids, stat.

“With normal hydration, the pinched skin should return back to normal essentially immediately,” says Pickels.

With moderate to severe dehydration, it will be slow to return.

“Try it now (I know you are) by pinching your skin for 2 to 3 seconds and then letting go. That’s your baseline,” he says.

Smelly urine can be a sign of dehydration

If nature calls and it smells like you’ve wandered into a bus station bathroom, that’s another good sign to drink more.

“A strong urine smell can be a sign of dehydration,” says Pickels.

Of course, it’s still good that you have to pee at this point, since once you hit severe dehydration, urine production decreases dramatically. Avoid slipping into that next stage by boosting your fluid intake as soon as possible.

We need water as much as the air we breathe in! Keeping your body hydrated is not a joke.

Did you know that dehydration actually sets in just before you start feeling thirsty? Sipping water throughout the day is the best way to handle it. Always have a bottle or a glass of water handy! If you’re not a morning person, having two glasses of water right after you wake up will boost up your blood pressure to normal levels, and it’s way healthier than having your first coffee on an empty stomach.

Many of us believe that merely drinking fluids like sweetened juices, soda or tea will hydrate you as well as water does. This is not true. It’s actually the opposite! To deal with the excess sugar and salt you are taking in your body wastes immense amounts of precious water just to clean it out from your system. And if you love your coffee, make sure to drink one extra glass of water for every cup you have.

Drinking water regularly speeds up your metabolism and makes you feel more ‘full’. You will eat less once you start drinking more! It’s the safest and healthiest way to lose weight. Drink up!

Beauty Benefits of Drinking Water

We all know not drinking enough water can cause the body dehydration and in the meantime obviously make us very thirsty. But, not only is purified water good for the body and the way we feel, but also the way we look. Have you ever stopped and wondered…what are the affects that dehydration is having on our appearance?

Our body is made up of roughly 70 percent water, which keeps our cells plump and healthy. When you don’t drink enough purified water, the effect of dehydration sucks all the moisture from our body and leaves our organs no choice but to steal that moisture from our skin, hair, and fingernails.  By stealing the moisture, it leaves our skin looking and feeling dry, hair looking lifeless and dull, and nails brittle and weak. Now I don’t know about you, but that is not the look I am going for.

When we’re talking appearance, these are the 3 parts of our body that suffer the most when we aren’t getting enough purified water:

Skin

Your skin is the largest organ of the body and skin cells like any other organ cells require water to function properly.  You need to drink throughout the day, whether you are thirsty or not, to help keep your skins’ moisture and elasticity. Improvements to the skin are often the most obvious benefits of drinking purified water, along with improved energy.  One of our customers, Angela from Coombabah, suffered from really bad eczema and since only using the  chemical free water her skin started to clear up!

 

Hair

Our hair thrives on moisture-rich environment and purified water is one of the best ways to quench its thirst. Just like our skin, hair also needs lubrication from inside out. Dehydration has a direct impact on the growth and a lack of moisture results in dry and brittle hair. It may even stop growing at the maximum genetic rate if you don’t drink enough purified water to meet your daily needs.  Why not also protect your hair even more by showering in chemical and chlorine free water.

 

Nails

Just like the water in your hair and skin, the water in your fingernails is important to the healthy look and feel of your nails.  Purified water will help in keeping your nail plates healthy and this will provide a strong base for your nails to grow. If you walk around dehydrated all the time your nails will be dry and brittle and they will peel and break easily.

 

Drinking purified water helps replenish the moisture back in our bodies and thus helping skin to be more supple and radiant, hair to be shinier and even nails will grow longer and be less brittle. To make sure you’re staying hydrated, be sure to keep a water bottle with you throughout your day and fill it up with purified water from your Pure Water Systems Water Purifier.

Is drinking extra water good for your skin?

Posted by

If you yearn for smooth skin that glows with youth, the chances are that at some point you will have heard the exhortation to drink lots of water in order to flush out those evil toxins and keep your skin healthy.

The exact amount people suggest varies. US-based advice tends to recommend eight glasses a day, while in hotter climates people are advised to drink more to compensate for higher rates of sweating. But regardless of the exact volume of water suggested, the principle behind the advice remains the same – taking extra water on board will keep your skin hydrated. In other words, water acts like a moisturiser, but from the inside out.

This is such a common idea you might be surprised at the lack of evidence to back this up. You might expect there to be countless studies where people are separated into two groups, one assigned to sip water all day, the other to drink a normal amount. Then the smoothness of the skin could be assessed a month or so later to establish whether sipping more led to smoother skin.

In fact such studies are rare, partly because water can’t be patented, so it is hard to find anyone to fund such research when there will be no new medication or cosmetic to sell that could repay the costs.  A review by the dermatologist Ronni Wolf at the Kaplan Medical Centre in Israel found just one study looking at the effect of long-term water intake on the skin. But the results were contradictory. After four weeks, the group who drank extra mineral water showed a decrease in skin density, which some believe suggests the skin is retaining more moisture, while those who drank tap water showed an increase in skin density. But regardless of the type of water they drank, it made no difference to their wrinkles or to the smoothness of their skin.

That’s not to say that dehydration has no effect on skin. We can measure some effect through the assessment of skin turgor. This is a measure of how fast it takes the skin to return to normal if you pinch some skin and lift it up. If you are dehydrated your skin will take longer to get its shape back.

But it doesn’t follow that because drinking too little water is bad for the skin, drinking above average quantities is good. It would be like saying that because a lack of food leads to malnutrition, overeating must be good for us. Or as Wolf puts it, it’s like saying a car needs petrol, therefore the more petrol the better.

Mystery advice

Another common belief is that if you drink extra water the body will somehow store it. But it depends on how fast you drink it. Drink several glasses within a fifteen-minute period and you will just pass extra urine. If you spend more than two hours sipping the same amount, more liquid is retained.

There is one study suggesting that drinking 500ml of water increases the blood flow through the capillaries in the skin. But the skin was only evaluated thirty minutes after drinking the water, and what we don’t know is whether this in turn improves skin tone.

One counterargument is that skin contains up to 30% water, and this helps it to look plump. This may be true, but the skin’s youthful appearance is affected more by factors such as genetics, exposure to the sun and damage from smoking.

So the mystery is where the eight-glasses-a-day recommendation for good skin comes from. Few of the official guidelines even refer to the skin. Water is undoubtedly the most important nutrient for the body. Without it we die in a matter of days, and there are of course other health benefits from staying hydrated. A review in 2010 found good evidence that it reduces the recurrence of kidney stones in those who have already had them, but evidence for other specific benefits is weaker.

 

Rural communities across Africa may soon benefit from improved water supplies thanks to mobile phone technology.

Arguments rage over the eight glasses a day rule, with disputes over how much is needed to clear the kidneys of toxins and whether or not water helps curb the appetite. It depends on how high the ambient temperature is and how much you are exerting yourself. It’s also a myth that other liquids don’t count. It doesn’t have to be water. Even food contains more liquid than you might expect.  Pizza is 40-49% water, for instance. The percentage of water we derive from food in the diet depends on where you live. In the US it’s 22%. In Greece, where people eat more fruit and vegetables it is much higher.

So the problem is a general lack of evidence that drinking more water makes any difference to your skin. We can’t say it definitely doesn’t work, but there’s no evidence that it does. Which leaves the question of how much water you should drink. Since it depends on the weather and what you are doing, then there is a very good internal guideline we all have that can help. And that’s thirst.
