Effects of Alcohol on Sleep

disturbed sleepMany of you will say that you need a drink in order to sleep, that alcohol actually helps you sleep better. While it may be true that drinking will get you off to sleep quicker, unfortunately the quality of your sleep will be much worse overall.

Alcohol inhibits the brain from entering REM stage sleep, which is when we do most of our dreaming, and prolongs the initial stage of deeper sleep. So when you wake up, you will probably not have dreamt enough – and dreaming is an essential component of sleeping. That or you wake up early once the alcohol has worn off.

Alcohol also inhibits your kidneys from absorbing water, so you tend to urinate more, and end up dehydrated. This further disrupts the quality of your sleep, and often produces a headache by morning. As such you end up feeling tired and unable to concentrate for the rest of the day. If you drink every evening, then you may be chronically sleep deprived, even though you might sleep all night, the quality of your sleep is not what it should be.

Making the transition to drinking less is often marked by a difficulty in falling asleep however, so you’ll have to readjust to dropping off naturally again. Getting regular, strenuous exercise is a good idea then – if you’re physically tired you’re much more likely to be able to sleep without needing your usual ‘knock-out drops’.

Dangerous Levels of Drinking

alcoholic drinkingAccording to figures released today by the NHS:

  • 1 in 4 adults are drinking at hazardous levels,
  • 1 in 10 men are on the verge of alcoholism,
  • 1 in 6 women drink at levels sufficient to damage their liver or lead to depression,
  • 1 in 10 men and 1 in 25 women are approaching alcohol dependence (admittedly rather vague terminology).

We have to ask ourselves why people in the UK seem to be developing more problems with alcohol, and what can be done about it. The cost to the health service alone is staggering – presently some £2.7 billion. That’s before we even consider the personal and social costs involved.

Alcohol causes increased breast cancer risk

alcohol causes breast cancerEveryone knows that alcohol causes harm like brain damage and liver cirrhosis. What most people aren’t aware of is that alcohol consumption also causes cancer. Recent studies show an increased risk of colorectal and breast cancer, liver and larynx cancer from regular heavy drinking.

The Harvard Centre for Cancer Prevention found an average of two alcoholic drinks per day increases the risk of breast cancer by about 25 percent.

Swedish scientists have found this risk to be exacerbated by Hormone Replacement Therapy (HRT). And the more you drink, the higher the risk. If you combine this risk level with the other well-known risk factors, such as a young age for starting your period (12 years or less), or a close female relative who has had breast cancer, then you really should consider cutting down on your alcohol consumption.

Cornell University have an informative summary of the issues involved with alcohol and breast cancer.

Abstinence reduces alcohol damage to brain & nervous system

alcohol nerve damage repairs itselfBecause alcohol is highly neurotoxic, as we’ve said before, it leads to damage of the brain and nervous system. Over time it can cause cognitive deficits, or loss of mental abilities in areas such as memory, concentration, motor control and ability to learn.

However, there is some hope now that those precious brain-cells are not lost for ever. Researchers at Stanford University have found that after at least six months of sobriety, the brain damage caused by alcohol’s toxicity does in fact repair itself.

They concluded that the mental abilities of their study group of long-term alcoholics, who had all been sober for between six months and thirteen years, were now the same as their control group who had not been alcoholics. The only capability that had not been recovered was spatial awareness.

Surely this is information to further motivate anyone who’s alcohol consumption is out of control – if you keep drinking, you’ll gradually lose all your faculties. If you stop, you’ll be dazzling friends with your razor-sharp wit just like you used to, right?

Antioxidants reduce the toxic effects of alcohol

brain damage from alcoholFor those of you who are drinking too much alcohol, but aren’t yet ready to change, here’s some useful health advice.

Alcohol is highly neurotoxic, meaning it directly destroys nerve cells – both those in the central nervous system (the brain and spinal chord), and those in the peripheral nervous system (the rest of the body).

Unfortunately nerve cells do not regrow as well as ordinary tissue, so such damage can be irreparable.

This can have a number of unpleasant effects, from peripheral neuropathy (pain, numbness or tingling, especially in the extremities), to atrophy of brain tissue.

In alcoholism particularly, this damage to brain tissue can cause a condition known as Korsakoff’s Syndrome. This is similar to Alzheimers, and is characterised by short-term memory loss and confabulation (making things up).

Fortunately though, some of this damage can be prevented with proper nutrition, or more easily, with vitamin supplements. Common vitamins called antioxidants can help the brain deal with the effects of alcohol by limiting the damage to nerve cells. These include the vitamins A, C and E plus the mineral Selenium. The vitamin Thiamine (B1) is also essential in preventing the onset of Korsakoff’s. They are all available in most health stores.

Of course taking vitamins won’t eliminate the toxic effects of alcohol, so don’t think that by popping a whopper mega-vitamin tablet every day you can magically drink as much as you like. It doesn’t work like that. But you might just lessen the damage a little.
