For boosting epinephrine and dopamine levels, there are several effective alternatives to ice baths and short intense exercises. Some of these methods include:

1. High-Intensity Interval Training (HIIT): Engaging in sprints or weightlifting is known to increase both epinephrine and cortisol levels, providing a similar energy boost as cold exposure 1.
2. Deep Breathing Exercises: Techniques such as Wim Hof breathing can significantly elevate adrenaline and help increase alertness, serving as an alternative to high-intensity physical activity 1.
3. Supplements: Supplements like L-Tyrosine, Alpha-GPC, and caffeine can be effective for enhancing focus and concentration without the need for physical stressors. These can be used in combination for maximizing focus 2.

Regarding alternatives to visual focus exercises like Trataka for improving acetylcholine availability, consider the following:

1. Binaural Beats: Listening to binaural beats can enhance concentration throughout work sessions 2.
2. Mindful Meditation: Practices that focus attention away from distractions without intense visual input can help prepare the brain for cognitive tasks.

These alternatives offer a range of ways to enhance energy, focus, and cognitive readiness, providing flexibility beyond cold exposure and traditional exercise routines.
