CPAP therapy can have a great impact on heart health, especially for those with sleep apnea. Sleep apnea causes breathing to stop and start during the night, which can strain the heart and lead to issues like high blood pressure and heart disease. CPAP works by keeping the airways open to ensure uninterrupted breathing and improved oxygen levels while sleeping. This reduces the stress on the heart and can help lower blood pressure over time. Overall, using a CPAP machine not only enhances sleep quality but also supports better cardiovascular health.
