If you are someone who suffers from sleep apnea, you may have a hard time traveling. Sleep apnea is a medical condition categorized by lapses in breathing while an individual is asleep. Untreated it can be life-threatening, though most often it causes an awful night sleep with very frequent waking episodes. Fortunately, sleep apnea can be treated with a continuous positive airway pressure (CPAP) machine. Some people with less severe sleep apnea simply leave their equipment at home and take the risk of sleeping without it, since it can be such a hassle to pack.
