Deep, restful sleep is enormously important for our holistic well-being: physically, emotionally and mentally. People who get enough sleep are less likely to suffer from obesity, high blood pressure and heart disease. Many beneficial regeneration processes take place in our body at night. In the deep sleep phase, stress hormones are reduced and growth hormones, also known as "anti-aging hormones", are released. Good sleep is also very important for a well-functioning immune system. Likewise for our brain. New synapses are linked and harmful substances such as beta-amyloid are broken down. Sleep disorders make us irritable, moody, nervous, impatient, unfocused and even depressed in the long run. Today, about 70 to 80 percent of the population suffers from intermittent and about 30 percent even from chronic sleep disorders. In this easy-to-understand book, Dr Craig Hudson explains the causes of insomnia. He addresses important influencing factors such as environment, diet, stress and lifestyle. He gives valuable tips on natural sleep aids and a lifestyle that can successfully solve sleep problems. His sleep tips and his 4-week programme have helped countless people worldwide to get a more restful sleep and thus a better quality of life.
