Sleep and Health
A For many years, scientists believed that sleep was a largely passive state in which the brain simply rested. As a result, early research paid little attention to what occurred during different sleep stages and instead focused on how long people slept.
B Advances in brain-imaging technology have transformed this view. Researchers now know that the brain remains highly active during sleep, carrying out essential tasks such as processing emotions and organizing memories formed during the day.
C A lack of sleep has been linked to a range of health problems. These include weakened immune function, increased stress levels, and a higher risk of long-term illnesses such as heart disease.
