Waking up groggy - high CO2 levels in bedroom?

[Marcos]

Nah, cheaper!

Something like this:

They're not very accurate or even that well built, but it's good enough.

I won't get that one just on the principle of them using "Vintage" in the title :-p

We always have the bedroom window open at night. Simply because it is easier to sleep when the air is cool and fresher.

Could be worse, my 3rd year Bio teacher made me inhale & exhale air in a jar over water to test this. After one recycled breath you can't really tell the difference: two starts to feel a little odd, after the third it's downright awful and a struggle to make yourself breathe the air again.

Oh it was much much worse than that. Re-breathers, scrubbers.. all sorts of things were used whilst measuring various things. I won't go into the effects and detailed methods.

2000 vintage maybe

But you get the idea

How much does a canary in a cage cost?

Might be the cheapest solution.

The mention of 'groggy' made me think of the potential for carbon monoxide poisoning. I don't want to scare monger, but tiredness is a symptom.

Presumably you have one of these carbon monoxide detectors near you boiler. Maybe grab another and put it in the room, just to be on the safe side.

Would this be relevant if the entire building runs on electric? No gas at all. Or does something else cause CO?

No, an electric heater can't produce CO.

OR .... You may have a sleep disorder such as fibromyalgia, like I do

I wake up after 14 hours sleep and still feel ruff as old boots, but thats another story

Copied from CO2 Meter site:

CO is the result of oxygen-starved combustion in improperly ventilated fuel-burning appliances such as oil and gas furnaces, gas water heaters, gas ovens, gas or kerosene space heaters, fire places and wood stoves. CO is generated by any gasoline engine that DOES NOT use a catalytic converter

If you are going to measure CO2 levels over a period of time, you need a calibrated and repeatable method.

You might find some suitable products and more information here...

However, as g8ina says, have you ruled out a sleeping disorder, he mentions one, another possibility is sleep apnoea...
