Reducing High Blood Pressure to Support the Immune System.

Last week I chatted briefly about a condition called metabolic syndrome (MetS), and how it’s inflammatory effects can alter the normal functioning of lymphatic tissues involved in the immune response.

Now there are 5 risk factors that fall under the banner of metabolic syndrome, but in today’s post, I’m going to concentrate on High Blood Pressure, also known as hypertension.

First and foremost, something to keep in mind is that high blood pressure is an inflammatory disease that impairs immune function.  That being said, a compromised immune system also leads to inflammation, so it works both ways.

When the immune response becomes dysregulated, it causes the sympathetic nervous system (a fancy way to describe our ‘fight or flight’ stress response), to go into overdrive. This raises our heart rate and blood pressure (which is fine in the short term), but over the long-term, can lead to oxidative damage causing arterial stiffening and hardening of the arteries.

Picture a rusty pipe and this is pretty much what oxidative damage does to our inner piping, so definitely something we want to avoid!


Cardiovascular Disease and Shift Work:

Is There A Connection And If So, What Can You Do About It?

It’s certainly no secret that shift work is taxiing on our health in more ways than one.  In fact I’m sure you can appreciate first hand just how challenging it is to work irregular hours day after day after day … or should I say night?

But what about cardiovascular disease?

Does working shift work enhance our risks of developing cardiovascular conditions such as hypertension and coronary heart disease?

The simple answer is ‘yes’.

And whilst the mechanisms for doing so vary, the fundamental driver behind this, is unhealthy sleep patterns – which I’m sure every single shift worker on the planet can relate too.

But exactly how does lack of sleep raise our risks of developing cardiovascular disease?

Well it essentially comes down to an overactive sympathetic nervous system, otherwise known as the fight-or-flight’ stress response arm of the nervous system which instigates a lot of physiological responses within the body including the release of stress chemicals that raise blood pressure and heart rate.  One of which includes cortisol.
