What is cold shock?
A cold shock is when bacteria undergo a significant reduction in temperature, likely due to their environment dropping in temperature. To constitute as a cold shock the temperature reduction needs to be both significant, for example dropping from 37°C to 20°C, and it needs to happen over a short period of time, traditionally in under 24 hours. Both prokaryotic and eukaryotic cells are capable of undergoing a cold shock response. The effects of a cold shock in bacteria include: 1 Decreased cell membrane fluidity 2 Decreased enzyme activity 3 Decreased efficiency of transcription and translation 4 Decreased efficiency of protein folding 5 Decreased ribosome function

How does cold shock affect RNA?
Cold shock proteins also affect the formation of hairpin structures in the RNA, blocking them from being formed. The function of these hairpin structures is to slow down or decrease the transcription of RNA. So by removing them, this will also help to increase the efficiency of transcription and translation.

One way cold shock proteins are thought to function is by acting as nucleic acid chaperones. These cold shock proteins will block the formation of secondary structures in the mRNA during the cold shock, leaving the bacteria with only single strand RNA.

What happens when you get cold in the water?
Cold water shock causes you to gasp uncontrollably and panic, which often leads to drowning. The shock of entering the water triggers the automatic flight and fright response resulting in panic and confusion. This puts additional strain on the heart, further lowering skin temperature by shutting down the peripheral circulation.
