Rethink the just one drink mindset

Daily alcohol consumption - even a glass a day - increases blood pressure, according to a new analysis published in the journal Hypertension. The analysis of 7 studies involving 19,000 people challenges the prevailing notion that a single daily drink could be innocuous. Even people who drank one glass a day showed a link to higher blood pressure when compared to non-drinkers. Citro explains the science that says we may need to think about 'just one glass' .

Alcohol, blood pressure and heart health

It's no secret that high systolic blood pressure - a measure of the rate your blood is pumped from your heart through your body - can lead to serious health issues.

High blood pressure tends to correlate with cardiovascular disease - which is Australia's biggest killer.

Systolic blood pressure can easily be checked by a doctor or pharmacist and is often managed successfully with medication and lifestyle and diet changes.

Some people don’t experience any symptoms of high blood pressure but common signs of high blood pressure can include:

Persistent headaches: Frequent, throbbing headaches, especially in the morning, can be a sign of high blood pressure.  

Blurry vision: High blood pressure can damage blood vessels in the eyes, causing vision problems or sudden blurriness. If your vision seems unusually fuzzy, it's a good idea to get your blood pressure checked.

Fatigue and confusion: Feeling persistently tired, mentally foggy, or confused can be indicative of reduced blood flow to the brain due to high blood pressure.

Chest pain or irregular heartbeat: While these symptoms could signal various issues, including a heart attack, they can also indicate high blood pressure. It's crucial to seek medical attention immediately if you experience chest discomfort.

Shortness of breath: If climbing a flight of stairs leaves you more breathless than usual, it might not just be due to lack of exercise. High blood pressure can strain your heart, causing shortness of breath.

Nosebleeds: While not always linked to high blood pressure, frequent nosebleeds can sometimes be a sign of elevated blood pressure levels.

Flushing or facial redness: An unusually red face, particularly if it occurs suddenly and frequently, could be a result of elevated blood pressure.

Difficulty sleeping: If you're struggling with sleep, whether it's difficulty falling asleep, staying asleep, or experiencing restless nights, high blood pressure may be worth looking at.

Swelling: Swelling in the legs, ankles, or feet, especially if it's accompanied by other symptoms like shortness of breath, could indicate high blood pressure-related heart problems.

Dizziness or lightheadedness: Frequent bouts of dizziness or feeling lightheaded could be due to changes in blood pressure, potentially caused by hypertension.

Regular blood pressure checks are more important for people with risk factors like a family history of hypertension, a sedentary lifestyle, poor diet, or other health conditions.

Detecting and managing hypertension early can significantly lower the risk of heart disease, stroke, and other health complications.  

What the new science says about alcohol and blood pressure

Contrary to the popular belief that moderate alcohol intake could be harmless, this study underscores the need to reconsider the 'just one drink' mindset, as even low-level alcohol consumption has been linked to elevated systolic blood pressure (SBP).

The force exerted on blood vessels when the heart pumps blood, known as systolic blood pressure (SBP), can be impacted by even minimal alcohol consumption. The research revealed this impact was consistent across individuals with no history of hypertension.

The study authors didn't expect to find that an already-low level of alcohol consumption could be linked to elevated blood pressure changes over time, even when compared to no alcohol consumption.

It’s opened up a new avenue of exploration into the complex relationship between alcohol and blood pressure dynamics.

Interestingly, original research deviated from convention by analysing the grams of alcohol consumed rather than the number of drinks.

This approach aimed to eliminate biases arising from varying alcohol content in 'standard drinks' across different countries and beverage types.

The study's results highlight a strikingly clear pattern: the more alcohol consumed, the higher the systolic blood pressure reading.

This linear association challenges the assumption that a certain threshold of alcohol intake could be considered harmless. Whether it's a single drink or more, the upward trend in blood pressure remained consistent.

And the idea of a glass of red wine a day … hmm, maybe not

This research also dismantled the notion that moderate alcohol consumption might confer health benefits.

There were no positive effects in adults who consumed a low level of alcohol compared to those who abstained completely, dashing the hopes of those who believed in the 'one-drink' theory for potential health advantages.

But what if my blood pressure isn’t high?

For people who notice even a slight increase in their blood pressure, regardless of whether it's officially categorised as 'high,' the study suggests that curtailing alcohol consumption or abstaining altogether might be beneficial.

Although the research indicated that genetic and environmental factors could interact with alcohol's effects in complex ways, the overall message was clear: alcohol's contribution to blood pressure elevation was significant.

In conclusion, this study may be a wake-up call for those of us who think 'moderate' alcohol consumption is all A-OK.

The evidence suggests that even a single daily drink can disrupt blood pressure dynamics, challenging the previously accepted safety of low-level alcohol intake.

There is a complex relationship between alcohol, lifestyle and individual health status.

It's not just the quantity of alcohol consumed but also how and when it's consumed that can significantly influence its effects on health.

The interplay between our lifestyle and physiological responses adds layers of complexity to being handed the wine list, right?
