  • Matching work schedules with circadian rhythms
  • Adapting to individual peak productivity times

Chronotypes and Societal Impacts

• Identifying Chronotypes
  • The concept of early (a person) and late (b person) chronotypes
  • Using tests to determine one's chronotype
• Consequences of Deviating from Natural Rhythms
  • Physical and emotional impacts

Health Risks and Genetic Factors

• Societal Pressures and Health
  • Risks for late chronotypes in a nine-to-five society
  • The concept of social jet lag and its health consequences
• Genetics of Chronotypes
  • The role of the superchiasmatic nucleus (SCN)
