Summary

This episode is brought to you by Puori, Cozy Earth, Fatty15, and Birch Living. Circadian rhythm is one of the most overlooked drivers of long-term health. It influences when we sleep, how we metabolize food, how our brain repairs itself, and even how our immune system functions. When this internal clock falls out of sync, the effects ripple through every system in the body. Today on The Dhru Purohit Show, Dhru sits down with circadian biology expert Dr. Satchin Panda to explore the four pillars of circadian health and how losing alignment can contribute to cognitive decline and Alzheimer’s disease. Dr. Panda shares key strategies to reduce your risk and breaks down the science behind why protecting your master clock is critical for preventing chronic disease. He also explains the importance of time-restricted eating, how timing influences the effectiveness of medications and cancer immunotherapy, and the role exercise plays in detoxification. Dr. Satchin Panda is a world-renowned pioneer in circadian biology and a Professor at the Salk Institute for Biological Studies, where he holds the Rita and Richard Atkinson Chair. Recently named a semifinalist in the XPRIZE Healthspan competition, Dr. Panda leads "Team Circadian" in groundbreaking research to reverse biological aging through rhythmic optimization. His discovery of the blue-light sensitive protein melanopsin and his extensive research on time-restricted eating have reshaped global health guidelines, leading to featured presentations at premier international forums including the American Diabetes Association and the professional diabetes societies of Europe and Australia.

0:00.0	Dr. Suchin Panda, world's leading expert on circadian biology, ton of research inside of the space.
0:08.2	Professor at the Salk Institute, welcome back to the podcast.
0:11.9	You know, our last interview together, largely because of you, I had nothing to do with it, has over a half a million views on YouTube,
0:20.1	hundreds of thousands of downloads on audio, and we have
0:23.3	you back on the show today to remind us that your body has a master clock and that almost everything
0:33.2	about how long and how well you live depends on whether or not you're working with it or against it.
0:41.3	And so we're excited to dive deep into a whole bunch of new topics.
0:45.0	And one of the top ones that we want to get into is tell us what we know now.
0:50.9	In 2026, when it comes to the intersection of cognitive decline, Alzheimer's, and circadian biology.
0:59.2	So what do we know now? So what do you think of cognitive decline? The only sign of cognitive
1:04.7	decline is actually depression. In many people, there is loss of interest in regular day-to-day life.
1:12.6	And people usually close themselves.
1:14.6	They're not mingling with other people anymore.
1:19.6	So let's break it down to depression is one aspect.
1:23.6	Then the other aspect is the sleep may be disturbed.
1:28.3	And we are actually seeing both in humans and also laboratory models that years before
1:36.3	the onset of dementia or mild cognitive disorder, there is sleep disruption. These people cannot fall asleep easily, or if they fall asleep, then they wake up quite a few times,
1:50.0	or during daytime, they have excessive sleepiness.
1:54.0	So now we have depression and then sleep disruption.
1:59.0	The third thing that is emerging slowly slowly and now there is a lot of
2:03.2	human studies pointing to and you mention that now the physicians are saying that you should
2:09.3	maintain a healthy body wet because what we now know is some people are describing dementia as type 3 diabetes.
