You’ve heard “Drink more water!” a million times
The thing is, the old ‘8 glasses a day’ rule doesn’t cut it for healthy ageing.
You need essential electrolytes and minerals to keep your body running smoothly and optimise your blood markers
In this article, we’ll uncover the real impact of hydration on your health, and why plain water alone isn’t the whole solution.
Let’s dive in.
How Hydration Affects Your Health Markers.
Since your body is over 60% water, hydration directly impacts every system, including the vital blood markers that show how healthy you are
Blood Pressure:
When dehydration lowers your blood volume, your heart works harder, which triggers vasoconstriction and raises your blood pressure
On the other hand, overhydration dilutes your sodium levels, which suddenly drops your blood pressure
Blood Glucose Levels:
When you’re dehydrated, your blood thickens, making it harder for your body to control glucose levels.
When you stay well-hydrated, you maintain normal blood volume, which helps control your blood sugar better.
Resting Heart Rate:
Dehydration increases your resting heart rate because your heart needs to work overtime to circulate blood.
Hydration supports a steady heart rate and reduces unnecessary strain on your cardiovascular system.
Just drinking plain water all day isn’t enough to maintain them effectively.
That’s where the right balance of electrolytes makes all the difference.
Let’s get into four key electrolytes that directly affect these blood markers.
The Role of Key Electrolytes in Supporting Blood Markers
Plain water hydrates well, but it doesn’t deliver the electrolytes your body needs to truly thrive.
Let’s break down how these powerhouse minerals directly impact your blood markers:
Magnesium
Magnesium, often called the “relaxation mineral” helps regulate and support cardiovascular health.
Regulates Blood Pressure
Magnesium helps to relax the smooth muscles in your blood vessels and reduces strain on your cardiovascular system.
It achieves this by controlling calcium flow within cells, which plays a crucial role in muscle relaxation.
A deficiency in magnesium can disrupt this balance that leads to higher BP and irregular heart rhythms.
Supports Muscle and Nerve Function
Magnesium is involved in over 300 biochemical processes in your body, including transmitting signals between nerves and muscles.
It helps regulate ion channels for your nervous system and ensures proper muscle contraction.
Works With Other Minerals for Heart Health:
Magnesium teams up with potassium and calcium to maintain a steady heartbeat.
This balance is disrupted when magnesium levels are low.
Natural sources: Leafy greens, almonds, and pumpkin seeds.
Sodium
Sodium often gets a bad reputation, but it’s essential for maintaining fluid balance and normal blood pressure.
Maintains Fluid Balance
Sodium is key for drawing water into your cells, helping your body stay hydrated.
It does this by interacting with chloride ions to create osmotic pressure, the mechanism that controls water movement between cells.
Regulates Blood Pressure
Sodium directly impacts blood volume, which affects blood pressure.
Too much sodium can cause water retention, increasing blood pressure, while too little can lead to low blood pressure and fatigue.
Sodium requirements change based on sweat loss, diet, and overall health.
For example, athletes may need more to compensate for losses during intense workouts.
And, those who eat a lot of processed or packaged foods should monitor their sodium intake carefully to avoid overloading their system.
Table salt is the easiest (and most obvious) source of Sodium.
Potassium
Potassium balances sodium’s levels and keeps your body’s fluid levels in check.
Balances Sodium’s Effects
Potassium helps relax blood vessel walls, which can offset sodium's tendency to increase blood pressure.
It achieves this by encouraging the excretion of sodium through urine.
Supports Cellular Functions
Potassium regulates the electrical activity in cells, especially nerve and muscle cells.
This ensures proper muscle contractions, including your heartbeat.
Dependent on Health Factors
Kidney function plays a huge role in maintaining potassium levels. Poor kidney health can lead to imbalances that impact heart and muscle health.
Natural sources - Coconut water, bananas, or sweet potatoes.
Calcium
Calcium is famous for building strong bones, but its role in heart health is equally vital.
Crucial for Muscle Function
Calcium ions are vital for muscle contractions, including your heart muscle.
It acts as a signal to the muscle cells, enabling them to contract and relax rhythmically.
Heart Rhythm Regulation
Alongside magnesium, potassium, and sodium, calcium helps stabilise your heart's electrical activity.
Deficiencies can disrupt this balance and lead to irregular heartbeats.
Natural sources -Dairy, tofu, and fortified plant milks (like almond or oat milk)
Why ORS Isn’t the Answer for Everyday Hydration
ORS (Oral Rehydration Solution) is the go-to choice for most people when they think of the word “electrolytes”.
And sure, it’s useful in medical emergencies like diarrhoea or vomiting.
But reaching for ORS every day just because you’re thirsty isn’t doing your body any favours.
Let’s see why.
The Science (and sugar) In ORS
WHO-approved ORS packs about 13.5 grams of glucose per litre. .
The sugar in ORS isn’t there by accident. There’s solid science behind it.
It’s designed for emergencies, not casual sipping
The glucose helps your body absorb electrolytes faster and gives you a quick energy boost. It’s perfect when you’re severely dehydrated or losing electrolytes rapidly.
The Problem with Daily Use
Using ORS for everyday hydration is like using a fire engine to water your garden.
The sugar load, while necessary in medical situations, adds up fast if you’re not actively sweating it off.
For those managing blood sugar levels, it’s even trickier. That much glucose can spike your levels and take away the benefits of staying hydrated.
When ORS Makes Sense
Now, don’t toss ORS out completely. It’s a lifesaver when the situation calls for it.
If you’re sweating buckets during a tough workout, running under the scorching sun, or working long hours in high heat, ORS can help replenish the electrolytes and energy you’re losing.
In those moments, it’s not just about water; you need sodium, potassium, and other minerals that plain water can’t provide.
Here’s the Balanced Approach.
For your regular thirst, stick to water and natural sources of electrolytes like coconut water, fruits, or lightly salted beverages.
Save ORS for when you really need it, for situations like
-
Intense workouts or endurance sports
-
Long exercise sessions in hot weather
-
Activities that leave you drenched in sweat
-
Recovering from illness with severe dehydration
