Your New Year Exercise Regime will Lower Blood Pressure (and so will Tongue Scraping!)

Your new 2021 Exercise regime can be fun, sociable and healthy.

(But, beware of what you do to remove post-exercise toxicity in the mouth)

The medical evidence strongly supports the view that, exercise will reduce our blood pressure’ and sodeliver health benefits such as better cardiovascular health’.

The reason exercise leads to lower blood pressure has been explained by Dr Raul Bescos, Lecturer in Dietetics and Physiology at the University of Plymouth and Lead Author of a new study in Science Daily:

"Scientists know that blood vessels open up during exercise, as the production of Nitric Oxide increases the diameter of the blood vessels (known as vasodilation), increasing blood flow circulation to active muscles".

That’s good to hear, because cardiovascular disease (CVD) is the BIGGEST killer of Men & Woman in the UK & USA.

Now imagine this.

You finish that healthy jog, gym class or football game, feeling very self-satisfied, but then notice a stale toxic taste in your mouth (its because your saliva has dried out allowing toxicity to build up).

What do you do?

Reach for some antibacterial mouthwash perhaps?


Medical Research shows that ALL the blood pressure lowering benefits of exercise can be destroyed if you do this!

The new University of Plymouth study, by Dr Raul Bescos, has managed to quantify the blood pressure-lowering effect of exercise when people rinse their mouths with antibacterial mouthwash, rather than water.

In the study, 23 adults exercised and then their blood pressure was tested under different scenarios - using an antibacterial mouthwash, a placebo and mint water.

The results showed that, when an antibacterial mouthwash was used (0.2% chlorhexidine), the blood pressure-lowering effect of exercise was diminished by more than 60% over the first hour of post exercise recovery.

And totally abolished two hours after exercise, when participants were given the antibacterial mouthwash.

That is a significant drop!

What’s going on?

(AMANO advocates will already know this, following the work of Dr Nathan Bryan, which we have showcased)

As we have seen, up to 50% of our DAILY Nitric Oxide production comes from ‘good’ Oral Bacteria – that’s Bacteria in our mouth! 

(See Note 1. if you want the Science behind this). 

And Bacteria activity and hence capacity to produce Nitric Oxide increases with exercise.

(See Note 2. if you want the Science behind this).

If you prefer, we have a neat Explainer Video that demonstrates the Science:



HOWEVER - using an antibacterial mouthwash will KILL off this ‘good’ Bacteria - thus reducing Nitric Oxide production!

As Dr Nathan Bryan reports in 'News Medical Life Sciences';

"The use of antiseptic mouthwash can kill commensal Bacteria and disrupt Nitric Oxide production putting patients at risk for CVD"

Top-Line: Using an antibacterial mouthwash can negate the blood flow benefits of exercise!

So what to do if you feel your mouth is stale post exercise?

Do what I do – use an AMANO Tongue Scraper ...


Don’t take my word for it – you will actually be helping your Nitric Oxide Production at the same time!

This is because, as Dr Nathan Bryan has gone onto show in his research, having a clean oral environment, for instance by scraping the Tongue, will actually increase our Nitric Oxide levels - and so further lower blood pressure.

He reported in ‘Frontiers in Cellular and Infection Microbiology’:

“Tongue cleaning frequency was a predictor of changes in systolic blood pressure and Tongue Microbiome composition. From our analysis, regular Tongue cleaning results in a Tongue Microbiome that has a greater ability to reduce Nitrite to Nitric Oxide, and conversely, failure to clean the Tongue daily results in a Microbiome composition that is less favourable to Nitric Oxide production."

Top-Line: Clean your Tongue and boost Nitric Oxide levels! (As well as removing bad breath)

If you are interested in reducing your blood pressure, in a natural 100% chemical free way, why not try using a Tongue Scraper?

Preferably an AMANO we would hope ...

How to use an AMANO Tongue Cleanser

If you are completely new to the tongue 'scraping' experience, we would suggest you hold the head of your AMANO under a warm running tap first - to provide an additional level of 'lubrication'.

This is how easy and quick it is to use an AMANO (we prefer holding a handle in each hand ... but each to their own)

NOTE 1: What is the precise chemical process for creating Nitric Oxide? Dr Nathan Bryan explains:

"The process is known as the 'Nitrate-Nitrite-Nitric Oxide pathway'. Good Oral Bacteria are 'Nitrate Reducers' that generate Nitrite as a by-product of converting ingested Nitrate-rich food, known as 'Arginine', which then builds up in our saliva. Once swallowed these Nitrites mix with stomach acid to produce Nitric Oxide – which then enters our blood stream".

NOTE 2: Why does exercise boost Nitric Oxide? Dr Nathan Bryan explains:

"When we begin to exercise, the increase in shear stress in the lining of the blood vessels tells the Endothelial Cells to make Nitric Oxide which lowers blood pressure.  That is the primary pathway.  Also circulating Nitrite that comes from the Oral Bacteria can be reduced to Nitric Oxide during exercise, especially under low Oxygen conditions and this will lower blood pressure".
