The 4 Chronotypes

1. 1. Lark: Larks prefer to rise early in the morning and wake up with energy. They are more productive in the first half of the day and tend to go to bed earlier.
   2. Owl: Owls prefer late nights and are more productive in the evening. They tend to go to bed later and have more trouble waking up earlier.
   3. Intermediary: Intermediary chronotypes tend to fall somewhere between morning and evening. They have more flexibility in how they wake throughout the day and follow a more traditional sleep schedule.
   4. Afternoon: Afternoon chronotypes usually have peak energy and productivity in mid-morning and afternoon. Early morning and evenings are difficult for this type.
