Alcohol is probably the most socially acceptable drug around, and for most of us who enjoy a beer, a glass or two of the old vino, or a G&T, it can be hard to even think of alcohol as a drug.
Indeed, alcohol could be considered an intrinsic part of leisure boating, a dead cert for Superyacht guests and a frequent way to relax off duty for anyone working at sea.
There have been multiple reports of people’s alcohol intake increasing during the lockdowns of the last couple of years and as it is so easily accessible, it’s a common ‘go to’ when people feel stressed.
Alcohol literally has been around since caveman times too! Late Stone Age jugs have been discovered, which suggests that intentionally fermented beverages existed as early as 10,000 BC. Use of alcohol can also reflect cultural and religious peculiarities as much as geographial and sociological conditions.
Seafarers must follow the drug and alcohol policy of the company or organisation that they work for, and the majority of leisure boaters are sensible and don’t drink until moored up for the night - the risks of drinking at sea are well known, well documented and can result in death or serious injury to yourself and others.
But what are the effects of alcohol short and long term? How do we know what our routine of a sundowner, or a quick drink when the sun is over the yardarm (which is always is somewhere in the world), is doing us some damage?
The effects outlined below assume a normal tolerance to alcohol. Dependent drinkers can often drink much more without noticeable effects. Remember that one unit is a pub measure of your chosen tipple or half a pint.
- 1 to 2 Units
- will speed up your heart rate and expand your blood vessels, giving you that warm, sociable and chatty feeling, associated with moderate drinking.
- 4 to 6 Units
- your brain and nervous system start to be affected, impacting on judgement and decision making. This can lead to more reckless and uninhibited behaviour. It also impairs the nervous system cells, making you feel light headed, slowing down reaction time and reducing co-ordination.
- 8 to 9 Units
- reaction times become much slower, speech slurs and vision begins to lose focus. Your liver (which filters alcohol out of the body) won’t be able to remove all of the alcohol overnight so you might wake up with a hangover.
- 10 - 12 Units
- co-ordination becomes highly impaired, vastly increasing the risk of an accident. The high levels of alcohol have a depressant effect on mind and body, making you drowsy. Levels of alcohol are now reaching toxic levels and your body will try to flush it out in your urine. This can cause dehydration an a severe headache. It can also upset your digestive system leading to nausea, vomiting, diarrhoea and indigestion.
- More than 12 Units
- an increased risk of developing alcohol poisoning, especially if you’ve drunk a lot of units in a short time. As a rough guide, it takes 1 hour for the liver to remove one unit from the body. Alcohol poisoning means the alchol is starting to interfere with the bodys autonomic functions, such as breathing, heart rate and the gag reflex which stops you from choking. It can even lead to unconsciousness and death. Deaths from aspirating on vomit are not uncommon when excessive alcohol is involved.
Some of the other risks involved with alcohol misuse include:
- Accidents and injuries. More than 10% of visits to UK A&E departments are alcohol related.
- Violence and antisocial behaviour. More than 1.2m violent incidents are linked to alcohol in the UK every year.
- Unsafe sex – this can lead to unplanned pregnancies and sexually transmitted infections.
- Many people lose personal possessions, such as their wallet or mobile phone, when they're drunk.
- Unplanned time off work or college, which could put your job or education at risk.
- Longer term, the effects of drinking large amounts of alcohol for many years will take its toll on many of the body's organs (brain, nervous system, heart, liver and pancreas), causing damage. It can also weaken your bones, placing you at greater risk of fracturing or breaking them.
- Heavy drinking can also increase your blood pressure and blood cholesterol levels, both of which are major risk factors for heart attacks and strokes. Long-term alcohol misuse can weaken your immune system, making you more vulnerable to serious infections.
There are many long-term health risks associated with alcohol misuse:
- High blood pressure
- Pancreatitis
- Liver disease
- Liver cancer
- Mouth cancer
- Head and neck cancer
- Breast cancer
- Bowel cancer
- Depression
- Dementia
- Sexual problems
- Infertility
And if this wasn’t enough, alcohol misuse can also have long-term social, as well as health, implications:
- Family break-up and divorce
- Domestic abuse
- Unemployment
- Homelessness
- Financial problems
So, let's imagine that we’ve had a run ashore and the alcohol has been flowing freely… how could you recognise if a colleague has alcohol poisoning and what would you do about it?
Signs
include confusion, vomiting, seizures, slow breathing, pale or bluish skin, cold and clammy skin, unconsciousness.
Of course if you’re on land, you can call for assistance from the emergency services. If not, you will need to manage carefully and constantly monitor your casualty.
Don’t try to induce vomiting as it could cause an airway problem. But lie the casualty on their side, ideally in the recovery position, so that any vomit drains away and the airway remains open. You can put a pillow or cushion under their head too.
If they become unconscious, they shouldn’t be left alone to sleep it off. Blood alcohol levels can continue to rise for 30-40 minutes after the last drink so symptoms can worsen and the risk of aspirating on vomit increases as they are unable to protect their own airway.
In most cases, the casualty will recover in time, drinking plenty of fluids (non alcoholic!) and with over the counter pain relief such as paracetamol.
However, if you are concerned, or symptoms seem to be worsening, consider contacting your shoreside medical support for advice. Remember that in the worst cases, alcohol poisoning can be fatal and clinical intervention may be required.
