How to optimize red blood cells

To optimize red blood cells, there are a few methods and considerations highlighted by experts on the Huberman Lab podcast:

1. Sauna Exposure: Engaging in sauna sessions, particularly after resistance training, can stimulate the production of red blood cells. This method enhances cardiovascular effort and blood volume, comparable to the benefits gained from altitude training. It involves a state of passive dehydration during training, which is extended by sauna use, thereby signaling the body to increase blood volume 1.

2. Iron Levels: While maintaining appropriate iron levels is important for red blood cell health, information from David Sinclair on the podcast suggests being cautious about excess iron. Too much iron can increase the number of senescent cells in the body, which can lead to inflammation and other health issues. Therefore, personalized medicine is crucial, taking into account individual iron baselines and needs rather than adhering to generic iron supplementation guidelines 2.

These practices, including sauna use and managing iron intake, can help in optimizing red blood cell production and maintaining overall health.
