Sleep isn’t a luxury; it’s the foundation of every system in your body.

In this episode of The Dr Kumar Discovery Podcast, Dr. Ravi Kumar explores the neuroscience, hormones, and daily habits that drive great sleep. You’ll learn how to optimize circadian rhythm, manage sleep pressure, and use proven evidence-based strategies to restore energy, focus, and long-term health.

In this episode, you’ll discover:

• What really happens in your brain during deep and REM sleep

• How your circadian rhythm and adenosine work together to trigger rest

• Why poor sleep drives insulin resistance, inflammation, and hormone imbalances

• The neuroscience behind light, temperature, and consistency as sleep levers

• How to use magnesium, glycine, L-theanine, and tryptophan safely for better sleep

• When melatonin helps (and when it doesn’t)

• Why CBT-I outperforms sleeping pills for chronic insomnia

• What to know about sleep apnea, the silent disruptor of deep sleep

Key takeaway:

Sleep is not wasted time; it is the nightly maintenance that keeps your brain, metabolism, and mood running at peak capacity. When sleep works, everything else works better.

Whether you’re struggling with insomnia, jet lag, or simply want to wake up sharper, this episode gives you a clear, science-based playbook to take control of your nights and your days.

When to Screen for Sleep Apnea

If you snore loudly, wake up gasping, or experience daytime fatigue, you may have sleep apnea. Take the STOP-BANG questionnaire here: http://www.stopbang.ca/osa/screening.php

If your score is high, talk to your doctor about a formal sleep study. Treating sleep apnea can dramatically improve energy, blood pressure, and long-term health.
