FARGO — If you've been feeling more tired when you wake up or throughout the day, a local sleep medicine specialist has some tips on how you could improve your sleep hygiene. ADVERTISEMENTWhen your alarm goes off, avoid hitting snooze and wake yourself up with light to suppress melatonin. And when you get out of bed, try some complex carbs and caffeine for breakfast, followed by some physical activity during the day. "To get a good sleep, physical activity in the daytime is extremely essential. The more the physical activity you had, you probably hear they sleep rock solid and they wake up in a better mood," said Dr. Arveity Setty, sleep medicine specialist with Sanford and Telesleep Clinic.
