Control Your Brain Chemistry for Focus, Motivation & Well-Being | Huberman Lab Essentials

About this video

In this Essentials episode, Huberman explains brain chemistry through four neuromodulators: dopamine, epinephrine, serotonin and acetylcholine. He describes slow baseline levels as the backdrop for any tool: from 0 to about 9 hours after waking, he says, dopamine and epinephrine tend to be highest; from about 9 to 16 hours they subside as serotonin rises; and the period from about 17 to 24 hours after waking is mainly for deep sleep. Acetylcholine, he explains, depends more on what a person is doing, such as focusing or learning. Huberman describes behavioural and supplement tools he uses, including deliberate cold exposure as a potent behavioural way to raise dopamine, and he discusses his own use of phenylethylamine and myo-inositol, with the specific amounts he mentions taking. He stresses that diet and regular behaviours should secure baseline levels first, and that no supplement should replace a physician-prescribed treatment, and any change to a drug protocol should be discussed with a physician.

• Huberman presents deliberate cold exposure as a potent behavioural tool for raising dopamine.
• Huberman discusses supplements he personally uses, including phenylethylamine and myo-inositol.
• Huberman stresses that supplements must not replace prescribed treatment and changes should be discussed with a physician.
