Sleeping with a CPAP machine can be life-changing for people with sleep apnea. After the first night, many users report waking up feeling more rested, alert, and refreshed. The machine prevents pauses in breathing, which means your body gets consistent oxygen supply. This leads to fewer morning headaches, less daytime fatigue, and better mood stability. Over time, CPAP use improves focus and even reduces risks of heart problems. If buying seems costly, a CPAP machine on rent allows you to try therapy without a big investment. Renting is especially useful for beginners who want to adjust before committing. With proper mask fit and consistency, the benefits become clear quickly—better sleep, more energy, and a healthier lifestyle overall.
