What Happens When You Don't Drink Enough Water? 10 Hidden Effects on Your Body

  1. What happens to your blood when you become dehydrated? Blood contains: Red blood cells. White blood cells. Platelets. Plasma, which is mostly water. Proteins, electrolytes, nutrients and other substances. When the body loses too much water, plasma volume can decrease. This can cause hemoconcentration, meaning some substances in the blood appear more concentrated. Possible effects include: Increased blood viscosity under some circumstances. Reduced circulating blood volume. Increased strain on the cardiovascular system. Reduced blood flow to organs in severe dehydration. This is different from having excessive cholesterol or fatty deposits in arteries. NCBI+2 2. Does dehydration increase cholesterol readings? This is where our article can become particularly interesting. A small human study involving 15 healthy participants found that fasting without fluid replacement produced higher measured total cholesterol, LDL cholesterol and HDL cholesterol than fasting with water and sal...

Over 50 and Still Active? Don't Assume Exercise Alone Protects Your Heart

 

You may know someone in their 50s or 60s who appears remarkably fit.




They play badminton regularly. They walk, cycle, golf, swim, or take part in other sports. They seem energetic and healthy.

Then, sometimes, something shocking happens.

A person suddenly collapses during or after physical activity, leaving their friends and playing partners stunned.

How can someone who looks so active and healthy suddenly have a serious medical event?

The uncomfortable truth is that looking fit and being physically active do not eliminate cardiovascular risk.

Exercise Is Important—but It Isn't the Whole Picture

Regular physical activity is an important part of a healthy lifestyle.

But heart health involves more than exercise.

Blood pressure, cholesterol, diabetes, smoking, excess weight, family history, age and diet can all contribute to cardiovascular risk.

Some conditions can also exist without obvious symptoms.

That's why someone can appear perfectly healthy while an underlying problem has gone unnoticed.

High Blood Pressure Can Be Silent

This connects directly with our previous article.

A person may have high blood pressure without feeling unwell. WHO describes hypertension as often having no symptoms, which is why measuring blood pressure is important.

Someone who plays badminton twice a week may therefore think:

"I'm active, so I must be healthy."

But physical activity doesn't tell you what your blood pressure is.

You need to check it.

What Does Food Have to Do With It?

This is where healthy eating comes into the picture.

Your diet can influence several cardiovascular risk factors.

A diet high in sodium can contribute to higher blood pressure, while a healthy eating pattern emphasizing vegetables, fruit, whole grains, pulses and healthier sources of protein can support cardiovascular health.

That doesn't mean a particular food will prevent a heart attack or sudden cardiac event.

It means that your everyday eating pattern is one part of the bigger picture of cardiovascular health.

Don't Wait Until Something Goes Wrong

For people in their 50s and 60s, being active is something to celebrate—not something to fear.

But being active shouldn't become a reason to ignore health checks.

If you regularly participate in vigorous sport, particularly as you get older, it is sensible to discuss your individual health and exercise needs with a healthcare professional.

And don't ignore warning symptoms such as chest discomfort, unusual breathlessness, fainting, or unexplained dizziness during exercise. Those symptoms warrant medical attention.

The Bigger Lesson

Perhaps the lesson isn't:

"Don't play badminton after 50."

It's almost the opposite.

Stay active—but know your health.

Exercise. Eat sensibly. Keep an eye on your blood pressure. Know your cholesterol and blood sugar when appropriate. Don't ignore unusual symptoms. And have appropriate medical check-ups.

Because health isn't determined by how energetic you look on the badminton court.

It is built from many factors—some visible, and some completely silent.

A Final Thought

We often congratulate ourselves for being active and assume that means we're safe.

But perhaps a better attitude is:

Exercise because you want to stay active. Eat well because you want to protect your health. And check your health because you cannot always feel what is happening inside your body.

That's very much in line with the message of Why Healthy Eating?: healthy living isn't about waiting for a problem before we start paying attention.
