Sometimes I need to drive through a crowded city and out to a neighboring village. Driving conditions can be quite dangerous--icy roads + poor visibility + numerous reckless, non-law-abiding drivers to contend with.
I want to be maximally alert and focused, and if I feel I need a boost, I use some or all of these aids:
Ice-cold shower (1-3 reps/ with energizing breathing) Short duration/high intensity cold exposure-->long-lasting increase in dopamine and norepinephrine. Fortunately the tap water here is extremely cold, otherwise I’d probably go for a short ice bath.
Coffee+cacao (sometimes green tea, if less caffeine preferred. Ideally I’d stop caffeine intake 10hrs before sleep time).
Nicotine lozenge (occasionally, 1/2 or less) Enhances alertness via dopamine, acetylcholine, norepinephrine.
