A Wakefield research study found that approximately 80 percent of adults use weekends to catch up on sleep lost during the week. A conscious failure to go to bed on time is not always the reason for this lack of shut-eye. Some people who struggle to get enough sleep have dyssomnia, a broad category of disorders that cause difficulty falling or staying asleep. Diagnosis of each disorder is a lengthy process that starts with medical consultation and leads to physical and psychological evaluations and treatment.


1. Insomnia

Insomnia is habitual sleeplessness. While it's common for everyone to experience trouble sleeping at times, excessive drowsiness and lack of energy from sleep problems that occur at least three times a week for at least three months signify chronic insomnia. One example is altitude insomnia, an intrinsic dyssomnia disorder. High altitudes reduce carbon dioxide levels, and the body doesn't use it to regulate breathing in the same way. During sleep, carbon dioxide levels drop to a certain level, and the drive to breathe turns off. When the body senses the drop in oxygen, breathing suddenly resumes, disturbing the sleep cycle. Experts suggest that increasing ambient oxygen levels with the help of a special device can improve restfulness.
