What are the hazards of sleep depravation? my husband only gets about 3-5 hours of sleep a night. he is very short tempered now and seems to have anger issues. could this be attributed to his lack of sleep?

Yes...failure : Yes...Failure to obtain adequate rem sleep deprives the body of its ability to "recharge" itself. Lack of sleep can lead to many physiological (high blood pressure, heart disease) and psychological (irritability) will result. Suggest you consult with a sleep specialist for a consultation and possible sleep study to determine why this problem is occurring. Most major hospitals have a sleep specialists.

There : There is no question that sleep deprivation could result in irritability, however it is very important to have your husband checked to be sure there isn't a more serious disorder. For example, bipolar disorder can cause both short sleep and irritability at the same time. I suggest scheduling an appointment with your family doctor or with a sleep specialist to take a closer look at what may be going on.
