Sleep apnea carries cardiac risks.

I read that sleep apnea raises blood pressure. What's the connection?

Larry, email

Sleep apnea is a condition that disrupts breathing patterns at night and causes carbon dioxide to build up in the bloodstream and oxygen levels to fall. Aside from wreaking havoc with natural sleep patterns, these changes trigger nerves to release adrenaline, elevating blood pressure, and potentially causing heart rhythm problems. High blood pressure can persist even after patients wake up and their breathing patterns return to normal. Treating sleep apnea, usually with continuous positive airway pressure (CPAP) machines that keep pressurized air flowing to the lungs, restores blood pressure to normal in most people.
