@8766c079: Dr. Kruse argues that natural sunlight exposure during the day is important for regulating circadian rhythms, which in turn can improve sleep, mood, and overall health. He suggests that getting sunlight exposure in the morning is particularly beneficial for setting the body's internal clock.

On the other hand, he believes that exposure to artificial blue light from electronic devices at night can disrupt circadian rhythms and interfere with sleep. He recommends avoiding screen time for at least 2-3 hours before bed, or using blue light blocking glasses if you must use electronic devices at night.

Overall, Dr. Kruse emphasizes the importance of balancing natural and artificial light exposure to optimize health and well-being.
