AMA #10: Benefits of Nature & “Grounding," Hearing Loss Research & Avoiding Altitude Sickness

About this video

In this AMA, Huberman addresses the benefits of nature and grounding, hearing loss research, and avoiding altitude sickness, focusing in the excerpts on nature. Huberman says there are dozens if not hundreds of quality peer-reviewed studies supporting getting sunlight in one’s eyes early in the day to set the circadian rhythm. He also says studies show that spending time outdoors in environments such as parks, streams, or ocean, for anywhere from 10 to 30 minutes, three to seven days per week, is associated with significant reductions in blood pressure and resting heart rate and improvements in sleep and mood. However, Huberman cautions that nature involves hundreds or thousands of variables, from sunlight and wildlife to air and soil smells, so isolating any single factor such as grounding in the laboratory would diminish what makes nature valuable.

Key takeaways

• Huberman says many quality studies support morning sunlight in the eyes for circadian rhythm.
• Huberman cites studies associating regular time in nature with lower blood pressure and resting heart rate and better sleep and mood.
• Huberman argues nature’s benefits involve hundreds or thousands of interacting variables.
• Huberman cautions against isolating single variables like grounding as the whole explanation.
• Huberman describes nature exposure broadly, including parks, streams, and ocean settings.
