Sleep disorders affect millions of people worldwide, disrupting rest and leading to daytime fatigue, irritability, and reduced productivity. Common conditions include insomnia, sleep apnea, restless legs syndrome, and narcolepsy. Poor sleep not only impacts mental focus and mood but also increases the risk of chronic health issues like heart disease and diabetes. Adopting healthy sleep habits such as following a regular bedtime routine, avoiding caffeine before bed, and creating a calm sleep environment can significantly improve rest quality. In some cases, medical intervention may be necessary to manage severe or persistent sleep problems.
