Sleep deprivation occurs when you consistently don’t get enough quality sleep. It can lead to both short-term issues, like trouble concentrating, irritability, and fatigue, and long-term health risks, including heart disease, obesity, and weakened immunity. Common causes of sleep deprivation include poor sleep habits, underlying medical conditions, or sleep disorders such as obstructive sleep apnea (OSA). Understanding the impact of sleep deprivation and how to improve your sleep quality is vital for overall health.
