In this episode of Dr. Mark Hyman's "The Doctor's Pharmacy," the focus is on tackling insomnia through a functional medicine lens. Dr. Hyman kicks things off with an introduction, followed by a deep dive with Dr. Andrew Huberman into the complex nature of insomnia. They discuss a range of factors that can contribute to sleeplessness, including gut health, deficiencies in key nutrients like iron, vitamin D, and magnesium, hormonal changes, heavy metal exposure, and even past traumas. The conversation wraps up with actionable tips for enhancing sleep hygiene, such as improving your diet and lifestyle, establishing a calming bedtime routine, and addressing psychological aspects. A standout message from the episode is the importance of identifying the root causes of insomnia, rather than just masking the symptoms with medication.
