Blood Pressure

High blood pressure, low blood pressure, what are you saying, doctors? What is blood pressure and why should we care?

What is blood pressure?

Blood pressure is the pressure that your blood exerts on the blood vessels. I know…. that’s a bit redundant.

Let me explain blood pressure a bit more, so you can visualize this. From what we’ve learned in school, the molecules in fluids interact closely with one another, meaning that they will not fill the entirety of a container unless you’ve placed enough of that fluid into the container to fill it completely. Each molecule exerts its own amount of force on each other and on the portion of the surface of the container that it interacts with.

Pressure is defined as a force exerted on a particular area. So the amount of force that the molecules exert on a particular portion of a container’s surface is equivalent to the pressure exerted by the molecule onto the container.

Now, if you replace the fluid with blood serum,the molecules with blood cells and the container with blood vessels, you’ll have the same situation; the blood cells each exert its own amount of force on portions of the blood vessel, which is the blood pressure.

Blood pressure naturally increases when your heart contracts to push blood into the blood vessels, and decreases when your heart relaxes.

Why is blood pressure important?

Blood pressure determines how hard your heart has to work to continuously feed your circulatory system with blood. The harder your heart works, the more strain there is in your circulatory system. This can lead to higher risk for health problems.

It’s also important to note that there are a variety of factors that affect blood pressure including how active you are, how much rest you get, your body temperature, diet, posture, medications and even your emotional state. So it’s important to try and stay healthy and active, for your heart and your health!

Alcohol – Effects on the Body

I’m a university student and you can bet that I’ve seen a lot of people under the influence of alcohol. They can be loud, giggly, emotional, and sometimes really tired.

I wanted to see just what effects alcohol has on our bodies, so posts about the different effects of alcohol will be popping up every now and then. For now, I thought it would be cool to see the list of effects alcohol has been found to have on our bodies.

Some of these effects are real extremes, so take them lightly. 🙂

List of the effects of alcohol on our body

Short-term effects

  • Nausea
  • Diarrhea
  • Makes you urinate more frequently (stay tuned, we’ll be talking about this one shortly!)
  • Flushed appearance
  • Reduced cognitive and motor skills(which is why you shouldn’t drink and drive!)
  • Loss of inhibitions and more confidence
  • Blurred vision (aka beer goggles) and slurred speech
  • Intense moods, e.g. aggression, elation, depression
  • Headache
  • Blackouts
  • Alcohol poisoning, which is really lethal

Diseases/conditions (in extreme cases!!!)

  • Can lead to the development of heart disease after long-term excessive use.
  • Potential cancer developing effects
  • May cause pancreatitis, which can lead to the development of diabetes
  • Liver disease
  • High blood pressure
  • Depression and/or anxiety
  • Weakened immune system
  • Anemia

Effects on our reproductive systems?!

  • Linked to damaging fertility (extreme case)
  • Small amounts of alcohol can affect a woman’s menstrual cycle
  • Alcohol can reduce the amount of testosterone a man produces
  • May affect the quality of a man’s sperm

And this is just a sampling of all of the effects of alcohol. In a couple of weeks, we’ll be talking about urination so that we can get to explore the effects of alcohol on it the week after :).

So, take it easy with eggnog for now, ladies and gents. No need to binge drink, it may just lead to some unhealthy effects!

I will be on hiatus until the first week of January, due to the holidays but Happy holidays and Happy New Year 🙂 Stay safe!
