Supercharge Exercise Performance & Recovery with Cooling | Huberman Lab Podcast #19

Caffeine Effects

Caffeine plays a significant role in thermoregulation and exercise performance. Andrew Huberman explains that caffeine can either aid or hinder performance depending on one's caffeine adaptation. For those who regularly consume caffeine, it can cause vasodilation, helping to dissipate body heat during exercise. However, for non-regular users, caffeine can increase core body temperature and constrict blood vessels, making it harder to manage heat during workouts 1.

If you're somebody who doesn't drink caffeine, drinking caffeine before a workout is going to be about the worst thing that you could possibly do.

Huberman advises considering one's caffeine habits before deciding to consume it around exercise times 2.

   

NSAIDs Impact

NSAIDs, like Tylenol and Advil, are commonly used to manage body temperature, especially during exercise. Andrew Huberman notes that these drugs can lower body temperature, which some athletes use to their advantage during prolonged exertion. However, he warns of potential side effects on the liver and kidneys, emphasizing the importance of monitoring body temperature and consulting with a coach when using these drugs for performance enhancement 3.

Alcohol, caffeine, and non-steroid anti-inflammatory drugs because of their effects on temperature will impact performance and recovery.

Huberman suggests using natural cooling methods, like cooling the palms or feet, as safer alternatives to pharmacological interventions 4.
