The danger of too much water.

I've posted before that the whole idea of having to have 8 glasses of water a day is a myth. In the primal blueprint there is also no need for so much water.


It all sounds nice and theoretical....until you see a story like this:

A mother died after drinking four litres of water in under two hours, an inquest has heard

Yeah, it's called hyponatremia. Basically, you start peeing out all your electrolytes because of so much water intake. The level of electrolytes in your brain stays pretty much the same. Since the brain/CSF fluid has a higher concentration of electrolytes now, the water rushes in to balance out the concentration of the blood and brain/CSF. Your brain swells, you die.

This can be easily solved by ingesting simple table salt if you suspect you or someone you know may have ingested too much water.

Happens a bunch especially to endurance athletes because they tend to sweat out a lot of their electrolytes and then hydrate with water. That's why it's important to ingest beverages with some form of electrolytes.

Hi there

yeah, I know it is hyponatremia.

i just wanted to highlight it again in this context - that we are told time and again to drink lots of water , but almost never warned of the dangers of too much. This woman was on a diet to lose weight and part of the recommendations were lots of water - she thought she was doing well but she killed herself.

very sad

Dry January

I mentioned a few weeks ago that I was taking part in "Dry January".  I didn't make a big song and dance about it, but I decided to go for a calendar month or so with no alcohol.  A few people have asked me about my experience, so here are a few points. Why take a break from drinking? Alcohol is an interesting topic.  As a drug it is widely accepted in society, central to so much of our socialising and leisure.  There seem to be lots of health benefits - so we are told - yet there are also a lot of problems in terms of health, relationships and lifestyle that come from drinking. Over a few years I'd begun to become aware and then concerned that I was drinking too much and too regularly.  I am in a busy and stressful job and sometimes a glass of wine after work to relax is really helpful.  But over time, one glass became two.  Two glasses became ....I might as well finish the bottle.  A habit got established....and was starting to get too e...

So where have I been?

You will have noticed that this blog has been quiet for a while....  There are a few reasons for that, reasons that I thought I'd list here: WORK -  my day job has been incredibly busy and stressful this year. Working 10-14 hour days the last thing on my mind when I got home was putting something on here.  FACEBOOK/TWITTER - I suppose I've been using other channels to do some of what I used to do here. Quick fire posts pointing to interesting studies or news etc tend to get posted to Twitter (@chrishighcock) or to the Facebook Hillfit group http://www.facebook.com/groups/263083947097000/  REASSESSMENT - I've found myself less comfortable with some of the positions I've taken in the past. Sometimes I'm embarrassed by some of the things I've promoted. I'm not Paleo or low carb. I think Tabata and intervals are misunderstood and misapplied. I cannot really claim to be HIT.   I find myselfunable  honestly to post things on here and pretend that I am some sort o...

Taking up space for a brief update

I've a couple of posts in draft that I will get up soon -  an update / reflection on Dry January and some thoughts on the scheduling benefits of short workouts if your life is busy.  Before that though, I am pointing to something else. However, I wanted to highlight something that is coming this weekend that I've been involved in.   Amber Rogers (Gokaleo and author of Taking Up Space ) has been pulling together a bundle of books from various authors with a common theme, one that I've been pushing here recently.   Keep it simple, avoid the hype, be patient, be consistent and flee the gurus.   I've talked before about how we get obsessed with pushing for more and more, when enough is OK.  I've given my view that so much of the health and fitness internet world is more like a gnostic religion than something that will benefit your life. There are other voices out there saying similar things and I'll be pointing to a bundle of books later this week ...
