Sunlight contains UV radiation. UV lamps are used to destroy the reproductive organs in pathogens. Therefore, in desperate times could one remain in the sun to keep a wound clean?

Unlikely. Remember that many pathogens already exist outside in the sunlight without dying.
I'm sure millions upon millions of organisms have died of infected wounds over the course of Earth's history even though they've been outside in sunlight.
You're much better off cleaning and bandaging a wound than to let it sit open.
Aero51 said:1) Does this mean that there are some pathogens that cannot be killed with UV radiation?
2) Isnt the only main reason an open would could get infected (barring things like being stabbed with a dirty knife/bullet/etc) is because you would sweat and the bacteria in the sweat could reach the wound?
Yes, sunlight can be used as a natural antiseptic due to its high levels of UV radiation. UV radiation has been proven to kill bacteria and other microorganisms, making it an effective tool for disinfection.
When UV radiation from sunlight penetrates the cell walls of microorganisms, it damages their DNA and prevents them from reproducing. This ultimately leads to their death, making sunlight an effective antiseptic.
Sunlight has been found to be effective against a wide range of bacteria, including E. coli, Salmonella, and Staphylococcus. However, some bacteria may be more resistant to UV radiation, so it may not be effective against all types.
Sunlight can be a reliable method for disinfection, but it is not always as effective as traditional antiseptics or disinfectants. Factors such as cloud cover, time of day, and season can affect the amount of UV radiation reaching the surface and therefore its effectiveness as an antiseptic.
While sunlight has been proven to be an effective antiseptic, there are some potential risks and side effects to consider. Prolonged exposure to UV radiation can be harmful to human skin, so it is important to use caution and limit exposure when using sunlight as an antiseptic.
