Lack of salvia hinders digestion. A study of people complaining of sleep problems suggests that these people spend too much time in bed. Sleep problems often disappear when the patients stop using their beds for anything but sleep. The subjects in the study group were instructed not to read, watch television, or eat in bed, and were to get out of bed if they were unable to sleep. This allowed the body to associate being in bed with sleeping, and made it easier for them to get to sleep when they did go to bed.
Many women suffer backache after having epidural anesthesia during childbirth.
This backache may persist for over a year. This study suggests that 8 out of every 100 women who have epidural anesthesia develop backache, which may become chronic. Frequency of intercourse, even with only one partner, also increases the risk of pelvic inflammatory disease. Those who had intercourse six or more times a week were 3.2 times more likely to develop pelvic inflammatory disease than those who had intercourse less than once a week. Obstetricians have routinely prescribed anticonvulsants in these women in the hope of preventing convulsions.
