Sleep apnea negatively affects physical health by interrupting normal breathing during sleep, leading to oxygen deprivation and poor sleep quality. This condition can increase the risk of serious complications, including hypertension, heart disease, and stroke. Additionally, sleep apnea can contribute to excessive daytime sleepiness, impair cognitive function, and negatively impact mood. Treating sleep apnea not only enhances sleep quality but also improves overall health and well-being, allowing for more effective participation in physical activities.
