Stress and anxiety may contribute to the worsening of sleep apnea, but are not a direct cause of sleep apnea. Sleep apnea, especially obstructive sleep apnea (OSA), is primarily caused by physical factors such as airway blockage and muscle relaxation during sleep. However, stress and anxiety may indirectly worsen sleep apnea by increasing muscle tension, disrupting sleep patterns, and consequently reducing sleep quality. In addition, anxiety can cause hyperarousal, making it difficult to fall asleep and stay asleep, while stress can contribute to weight gain, a significant risk factor for sleep apnea. Therefore, managing stress and anxiety is essential to improve sleep quality and reduce the effects of sleep apnea.
