Obstructive Sleep Apnea (OSA) is a serious sleep disorder where the airway repeatedly collapses during sleep, leading to disrupted breathing, loud snoring, and poor rest. Millions of adults, especially men over 40, are affected by OSA, often without knowing it. Common symptoms include excessive daytime sleepiness, morning headaches, poor concentration, and mood changes. Left untreated, OSA can increase the risk of high blood pressure, heart disease, diabetes, and stroke. Risk factors include obesity, smoking, alcohol use, and family history. Diagnosis usually involves a sleep study conducted by a qualified healthcare professional. Treatment options range from lifestyle changes and weight management to CPAP therapy and, in some cases, surgical interventions. Early management not only improves sleep quality but also enhances overall health and reduces the risk of long-term complications. Prioritizing sleep health is essential for better energy, focus, and well-being.
