Yesterday, I install an aircon(recycle air in my room). It's cool but when I woke up I feel headache. Why?

Question

The aircon is the type which recycle the air in my room. I wonder how does the oxygen came in thru the night. Is this the reason I feel headache?

Answer 1

If it strips away moisture as well it may have dried you out. The headache may be similar to a hangover due to the same reason. Check the box to see is it absorbs moisture. If so, invest in a cheap humidifier.

High oxygen usually gets rid of a headache and a machine would not be allowed to be sold if it reduced the amount in a room, that would just be dangerous.

Answer 2

#1 drink about 1/2 gallon of water per day - the head of neurorology at UCDavis (about 10 years ago) likened a car low on oil to a body low on water (engine siezing up).
#2 Daily muscle relaxer (1 or 2 swigs of molasses or 1 or 2 bananas) they contain magnesium and potassium.
#3 Massage therapy - professional or read The Trigger Point Therapy Workbook by Davies (it teaches you how). The principle that causes the headaches regardless of how severe is that muscles get knots (trigger points), which make the muscles stay tight, which press on nerves.
Your back, shoulders, neck and everywhere on your head will definitely play into the cause and it will take a while to get all the trigger points to go away.

Answer 3

It has nothing to do with your aircon per say. It is a simple matter of your system being dehydrated from a lack of moisture. TWO solutions. Cheap...drink 16oz of water 30 minutes to sack time. For a few buck, buy a humidifier and use that on the cycle mode.

One of the 1st things you learn when moving from a tropical environment to a "cold" climate.

Answer 4

dried the air out and dried out your nose and sinus's...dry sinus's can cause a headache...use some saline spray (for your nose)
bought at just about any store...
