min
Cold drinking reset
Breaks a low energy moment in two minutes.
Use this when
When an energy dip hits mid-day and you need something immediate without caffeine or leaving your desk.
After this
Most people notice a brief lift in alertness within a minute. The cold sharpens attention, the water addresses any mild dehydration that may be contributing to the slump.
You will need
A large glass of cold water.

The why
Cold water stimulates thermoreceptors that briefly activate the sympathetic nervous system, triggering a small noradrenaline release that increases alertness. Simultaneously, mild dehydration, which often accompanies afternoon energy dips, reduces cognitive performance; drinking water reverses this within minutes. Two mechanisms working together in one action.
