Dr. Darley gives us a new term (that we’re totally stealing!). Instead of describing light pollution to people as too much light, she feels people respond more positively to the problem if you describe it as a “darkness deficiency.” Dr. Darley goes on to explain the hazards of too much light – sorry, of a darkness deficiency – in your environment when you’re trying to sleep, like hormone imbalance, thyroid problems, and cancer risk. If you hold your arm out in the middle of the night and you can see your fingers wriggle, then there is not enough darkness in your room. Dr. Catherine Darley is the leader in natural sleep medicine. She combines her knowledge of sleep and circadian disorders with her training as a naturopathic physician to bridge these two fields. She’s treated patients for over 20 years, along with training healthcare providers in sleep medicine. Dr. Darley now focuses on teaching people sleep skills so they can thrive at home, at work, and have a high quality life. You can find her online at SkilledSleeper.com, on Instagram, and Substack.
