whether these symptoms are familiar to you:
• In the evening at work - brains "do not cook," do not want to do, just walk over the internet.
• When coming home, the forces only enough to sit on the internet the night before.
• You often wake up already tired.
• You notice that even one thing you sometimes difficult to keep in mind.
• You can forget that now wanted to do.
• In summer, all is well, and in winter - apathy, do not want to do.
All of this can be quite a trivial reason.
And the reason for this - an overabundance of carbon dioxide in the room.
Now the street an average of 400 ppm of carbon dioxide (ppm = part per million, 400 ppm - 0.04%), twenty years ago, it was about 350 ppm. Man feels fine when CO2 concentrations up to 700 ppm. At 1000 ppm there will be a bit stuffy.
Man indoors produces about 35.2 grams of CO2 per hour, the measurements showed that in 20m2 unventilated room in which there is one person, CO2 level rises from 400 to 1500 3 ppm per hour. If the room is two, respectively, for 1.5 hours.
In order to avoid the "poisoning" of carbon dioxide need to constantly ventilate the room and control the level of CO2.
For good ventilation is not sufficient to open the window a couple of times a day, you need to constantly ventilate. Winter or have to endure the cold or put a system of forced ventilation with heating.
Devices, showing the level of CO2 (CO2-monitors), are quite expensive.
I use the device with datalogerom and accurate hygrometer (humidity meter) AZ Instruments 7798 CO2 datalogger ( http://ammo1.livejournal.com/500385.html) behind $139.
Friends and relatives of all holidays bestow devices Dadzhet MT8057 ( http://ammo1.livejournal.com/791485.html) for 5450 rubles, or a previous version of the same device MASTER KIT MT 8057 ( http://ammo1.livejournal.com/613146.html), which can still be found for sale.
The cheapest measuring CO2 levels on Aliexpress worth $ 74.65 or 4756 rubles.
