Sleep difficulties refer to any issues or disruptions in the normal sleep patterns of an individual. This can include difficulty falling asleep, staying asleep, or experiencing poor quality sleep. Sleep difficulties can result from a variety of factors, such as stress, anxiety, medical conditions, or lifestyle choices. Chronic sleep difficulties can have negative impacts on physical, mental, and emotional health, leading to problems such as fatigue, mood disturbances, and impaired cognitive function. Research in this area focuses on understanding the causes of sleep difficulties, developing effective treatments, and improving overall sleep quality for individuals experiencing these issues. Additionally, studies may also explore the relationship between sleep difficulties and other health conditions, such as depression, obesity, and cardiovascular disease.
