Not only is sleep essential for healthy cognitive functions, it also assists in maintaining a balance of the hormones for both physical health and emotional well-being. For decades, a solid body of research has shown that a healthy lifestyle depends on getting quality sleep. Research shows that good sleep can be a natural immunity booster, and that adequate amounts of sleep are needed for optimal resistance to infectious diseases, particularly when coupled with diet and exercise. According to Health Affairs, up to 70% of our health is related to behavior, environment and physical influences. Quality sleep is critical to our well-being and fundamental to our health. It is the most basic of human needs, and yet most people are just beginning to understand its value. Lack of sleep has also been linked to several diseases and conditions prevalent today, including obesity, type 2 diabetes, heart disease and depression. Not getting enough quality sleep can also lead to injuries and disabilities caused by accidents on the road and at work. Numerous studies have found that insufficient sleep can impact everything from weight gain to mood regulation to general brain health. Moreover, lack of adequate sleep over time has been associated with a shortened lifespan.
