Don’t Rinse Your Toothpaste (and Other Pieces Of Advice)… True or Myth?

Throughout our lives, we are given random pieces of advice, and sometimes they stick and we insist on doing certain things, or avoiding certain things.

I decided to explore some of things I’ve been told, and see if they have any truth in them!

Advice:

After washing my hair, I have always given it a final rinse with cold water.

Why?

I was told that it makes your hair shiny and stops it getting damaged.

Truth:

It’s not true! The hair contains no living cells, so the temperature of the water makes no difference to the hair! Cold water could cause the blood capillaries in the head to constrict, so could actually impede hair health!

 

Advice:

I was told don’t rinse out your toothpaste- though I have always continued to rinse!

Why?

I was told that the toothpaste continues to protect and clean your mouth so it’s vital you don’t rinse it out.

 

Truth:

There’s arguments for both sides. If you rinse the toothpaste out, you are getting rid of the fluoride which continues to protect your teeth.

But on the flip side, by not rinsing you will be leaving bacteria in your mouth, plus fluoride can cause irritation if swallowed. So if you have, like me, always rinsed and never had a problem with your teeth- then there’s no harm in doing so.

As long as you properly clean your teeth for 2 minutes – and you could also enhance the protection from the fluoride by using your toothpaste mixed with water as a mouthwash before you spit it out.

 

Advice:

Sleep before midnight is more beneficial.

Why?

Apparently we can fall into a deeper sleep before midnight, giving us better quality of sleep.

Truth:

The truth is that the first third of our night’s sleep is the deepest and most restorative part. But it doesn’t matter when we get the sleep, as long as we’re getting enough! (see this previous blog post for info on how much sleep we need!)

 

Advice: 

Using a hairdryer is dangerous.

Why?

I cant remember the exact reason, but it was to do with something being emitted which is linked to causing cancer I think!

Truth:

Hairdryers, along with other household appliances (basically everything) emit electromagnetic radiation (like what X-Rays produce but milder), and studies have linked it to cancer, along with increasing the risk of other diseases such as Alzheimer’s, and other health risks.

So there you have it, it looks like most of the advice wasn’t complete rubbish, but doesn’t need to be strictly adhered to either!
