Huberman breaks from the main content to read a sponsor segment for Eight Sleep, maker of the Pod 5 smart mattress cover. He explains the physiological basis for the product's value: the body must drop 1 to 3 degrees in temperature to enter and maintain deep sleep, and must rise by the same amount to wake refreshed. The Pod 5's Autopilot feature uses AI to learn individual sleep patterns and adjust bed temperature accordingly, and can even elevate the head to reduce snoring. Huberman mentions having used Eight Sleep for nearly five years, and directs listeners to eightsleep.com/huberman for up to $350 off.
The Dedicated Grieving Session Tool
The most adaptive grief tool is a dedicated 5-to-30-minute daily session of consciously feeling the depth of attachment to a lost person, while actively blocking counterfactual 'what if' thinking. This isn't wallowing — it's precisely calibrated neural remapping that separates the felt attachment from the episodic memory catalog.
