It's a basic necessity of life, as important to our health and well-being as air, food and water. When we sleep well, we wake up feeling refreshed, alert and ready to face daily challenges. When we don't, every part of our lives can suffer. Our jobs, relationships, productivity, health and safety (and that of those around us) are all put at risk. And lack of sleep due to sleep loss or sleep disorders is taking a serious toll.
