What is the purpose of the last sentence of the passage?
Doctors recommend that adults sleep between seven and nine hours each night, yet many people get far less. During sleep the body repairs tissue and the brain stores new memories. People who sleep poorly often find it hard to concentrate, and over many years lack of sleep is linked to health problems such as high blood pressure. Experts suggest a few simple habits to improve sleep: going to bed at the same time every night, avoiding caffeine in the evening and keeping screens out of the bedroom.
