Five Common Health Myths Debunked

Health myths can be particularly difficult to stamp out. When you’re raised with a false bit of wisdom that came from a well-meaning authority figure, it can seem like gospel. 
You may have held that belief for many years, carefully followed the advice, and shared it with other people along the way. After all that, it can be hard to let go.
So try to keep an open mind as you read through this list of five common health myths.

Eating Carrots Will Improve Your Eyesight

This health myth has a grain of truth to it, as carrots are rich in beta carotene. That’s an antioxidant that your body converts into vitamin A—which is essential in maintaining your vision.

However, the chances are very high that you already get enough vitamin A in your diet. So eating more carrots won’t improve your vision.

It’s true that research has shown that beta carotene can help people with age-related macular degeneration (AMD). But that research involved high-dose beta carotene formulas, not the lower amounts you’ll get from eating carrots.

Interestingly, this myth was popularized by the British Royal Air Force during World War II. In an effort to conceal their new radar technology, the RAF started a rumour to explain how its pilots were so successful at spotting enemy planes at night. The rumour was that British pilots ate lots of carrots.

Cracking Your Knuckles Causes Arthritis

When you crack a joint, what you’re really doing is slightly pulling the joint apart, which decreases the pressure in the fluid that lubricates the joint.

This pressure change allows bubbles to form and causes them to rapidly fluctuate. It’s this fluctuation that’s responsible for that satisfying cracking sound.

So, can these bubbles cause arthritis? There’s no reason to think so. A study from 2011 tried to find if there was any link between knuckle cracking and osteoarthritis and showed there was no connection.

You Can Catch a Cold From Being Cold

At some point, someone has probably told you to dress warmly or “bundle up” before heading out in cold weather, or else you’ll catch a cold. This piece of advice has been drilled into many of us so often that it could be easy to forget that the cause for the common cold is viruses, not chilly temperatures.

It’s true that some viruses spread more easily during the winter months, but the reasons for that might not be what you expect.

A common theory is that exposure to cold temperatures may temporarily weaken your immune system, making you more susceptible to cold viruses. There is some research that supports this theory, but it is not yet conclusive.

But one way you’re more likely to catch a cold during the winter is spending more time indoors. By spending more time in close quarters with other people, you make it easier for viruses to spread.

In addition, your immune system can be weakened by lack of vitamin D due to reduced sun exposure. So getting outside in the cold might not be such a bad idea!

You Should Drink Eight Glasses of Water a Day

You’ve probably heard that you should be drinking eight glasses of water a day to stay healthy. This often-repeated tip has been the popular opinion for decades. Eight glasses of water equals about 2 litres, which matches up with the most current recommendations from health researchers.

However, this recommendation doesn’t take into account the water you already get from other sources. For instance, other drinks will help you reach your recommended water intake. And besides the water you get from drinks, about 20 percent of the average person’s water intake comes from foods.

So don’t fret if you’re not drinking eight glasses of water a day. Just drink when you’re feeling thirsty and make sure you properly hydrate if you are very active or in a hot environment.

Microwave Ovens Can Cause Cancer

Part of this myth stems from people’s misunderstanding of radiation. You may know that certain types of radiation (such as x-rays from an x-ray machine, gamma rays from a nuclear explosion, or UV radiation from the sun) can harm your DNA and increase your cancer risks.

However, the radiation used in a microwave oven is very different. Similar to radio waves, microwave radiation is so low energy that it can’t harm your DNA. Besides that, microwave ovens are designed so that the radiation can’t escape. 

Some people also mistakenly believe that microwave cooking can adversely affect the food, or even make it radioactive. But once you understand how microwave ovens work you’ll see that there’s nothing to worry about. 

Microwave ovens produce microwaves that cause the water molecules in food to vibrate. This vibration produces heat, which is what cooks the food. So microwave ovens do not make any changes to the food that isn’t made by any other cooking method that involves heat.

Boost your immune system with these superfoods

There’s some wisdom in the old cliche that says “you are what you eat”. The foods you put into your body are what supplies it with the energy and vitamins it needs to work properly.

There are some foods that are so beneficial to your health that they become known as “superfoods”. If you’re not including them in your diet, you’re really missing out. 

These foods are packed with so many nutrients they can help you improve the way your body works, such as by boosting your immune system. 

Here is a list of great superfoods that do just that. And best of all, they are all foods that taste so good it will never feel like a chore to fit them into your diet!

Red bell peppers

When you think of sources for vitamin C, citrus fruits probably come to mind. But believe it or not, red bell peppers contain about twice as much vitamin C as citrus fruits.

Papaya

Papaya offers a number of benefits including B vitamins, folate, potassium, and a digestive enzyme that has anti-inflammatory effects. And as if that weren’t enough, a single papaya contains more than double the daily recommended amount of vitamin C.

Garlic

Garlic has a long history of being used for health purposes. Early civilizations including the Egyptians, Greeks, and Romans all understood that garlic has some special healing properties. Today, it is used in supplements for a variety of purposes including treating high blood pressure and high cholesterol. Some research suggests that the sulphur compounds found in garlic can boost the immune system.

Blueberries

Blueberries have a type of flavonoid called anthocyanin, which has antioxidant properties that can boost your immune system. 

Research has shown that flavonoids play a key role in the immune defence system of the respiratory tract, and that people who eat foods rich in flavonoids are less likely to catch a cold.

Dark chocolate

Dark chocolate contains an antioxidant called theobromine that can help boost the immune system. Theobromine’s benefits come from its ability to protect your cells from free radicals.

Free radicals are molecules that your body produces when it breaks down food or comes into contact with pollutants. These molecules can damage the body’s cells and may contribute to disease.

Ginger

Ginger has antibacterial properties and can help support your immune system, but its benefits don’t stop there. You may know that it’s an effective remedy for an upset stomach. It is also a natural blood thinner and contains an anti-inflammatory compound called gingerol that can help relax blood vessels.

Almonds

Almonds contain vitamin E which is essential to a healthy immune system. Vitamin E is a fat-soluble vitamin, which means in order for it to be properly absorbed into your body, it needs the presence of fat. Luckily, almonds also contain healthy fats!

Yogurt

Yogurt can benefit your immune system in several ways. Firstly, it contains vitamin D, which helps support and regulate the immune system. But it can also offer beneficial bacterial cultures that stimulate the immune system. When choosing your yogurt, look for ones that say “live and active cultures” on the label.

Remember to take your medication with these tricks

Do you have trouble remembering to take your medication? If so, you’re not the only one. Some research shows that 80 percent of patients occasionally forget to take their meds.

If you have several medications, keeping track of them all can get complicated. And if you miss a dose or can’t remember whether you took it or not, you might be left wondering what to do. Should you take the missed dose once you remember it, or wait for the next one?

Well, these tips will help. Here are some simple tricks that will help you remember to take your medications—and know what to do if you ever miss a dose. 

Weekly Pill Boxes

Weekly pill boxes that have a separate compartment for each day can be a big help when it comes to keeping track of your meds. There are also pill organizers with enough compartments to store all your meds for the month or organize your doses by the time of day.

So if you ever find yourself second-guessing whether you’ve remembered to take a pill, this simple solution can help.

Leave it Out

An easy way for remembering to take your medication is to leave your pill container somewhere you will see it. That could be the bathroom counter, on a nightstand next to your bed, or anywhere else you’ll look every day without fail. 

Reminder Apps

If you are one of the many people who treat your phone as an extension of your body, a medication tracking app may be the best solution for you. There are a variety of free apps available, and they make it easy to set up your medication schedule and get pill reminders when it’s time to take a dose.

These apps also let you set an alarm to let you know when a prescription is running low and it’s time to get a refill.

Make it Routine

Making medications part of your daily routine can take the effort out of remembering. So try to take your pills at the same time as a routine activity like brushing your teeth, or clearing the table after dinner.

By associating your medications with those things you know you do every day, taking your medications will become second nature.

Get Help

If you find yourself struggling with a complicated medication schedule, you should bring it up with your doctor or pharmacist. They may be able to help simplify your medication regimen. 

That may include prescribing different forms of your medications that don’t require as frequent a dose, or reducing the number of different medications you take.

What to Do if You Forget to Take a Medication

The recommendations for what to do after you forget a dose depends on several factors. That includes the type of medication and the severity of your condition. 

For example, some drugs have a longer half-life than others (meaning they stay in the body longer), so the odd missed dose is not a problem and you can just return to your normal schedule once you remember. The longer half-life also means that trying to make up for a missed dose is not a good idea, as it may cause an increase in side effects or other issues.

On the other hand, some health conditions require consistent doses of medications, and so it’s recommended to take the missed dose as soon as its remembered, unless your next dose is less than two hours away.

So speak to your pharmacist or doctor about the specific recommendations for your medications.
