“Larks tend to have lower heart rates, half as much sleep apnea and lower body weights than night owls,” says Jo Lichten, registered dietitian and author of the book “Reboot: How to Power Up Your Energy, Focus, and Productivity.” Owls, on the other hand, often have lower levels of HDL cholesterol, are snorers and have higher levels of cortisol, the stress hormone, says Pam Peeke, senior science advisor for Elements Behavioral Health. Owls are usually more anxious and depressed than larks, have a higher incidence of ADHD, consume greater amounts of caffeine and alcohol, and experience higher rates of addiction, Peeke says. “Morning people are more stress resilient and have a higher level of life satisfaction, with less substance abuse.” Owls, she adds, can stay better focused throughout the day, however, while a lark’s attention wanes by mid-afternoon.
