In evenings when the temp. falls down from 29 degree cels. to 28 or less I start yawning repeatedly. The frequency is 15 or more yawns per 10 minutes. This lasts for nearly one hour,making my jaw joints painful.The period of yawning is more when I am outdoors.I could not understand the reason. Some friends say that since I smoke , my lungs crave for more oxygen.Others thought that when the temperature drops,whatever CO 2 has risen up due to heat,during the day comes down to earth level,resulting in reducing the ratio of oxygen. But then yawning effect should cover every one.Will any one kindly explain it ?
