Life hacks are all over the place at the minute (seriously, they're everywhere) and some are really good – but often they're more Martha Stewart than Grizzly Adams.

Here are a few life hacks that are applicable not only to regular everyday lifestyles but to those crazy preppers – ahem – people who are of a preparedness mindset as well. While all of these aren't necessarily life-saving, they all have the potential to save you money and effort in a survival situation.

This sounds like more of a beauty tip than a prepper tip, but don't forget to moisturize! Your skin is a barrier that prevents infection. Keep it supple to prevent cracking which provides a route for infection to get into your body. This is an important infection prevention method if  antibiotics are either unavailable or no longer work.

Carry plain, refined sugar with you at all times. Those little sachets from fast food restaurants are ideal. Plain sugar poured into a wound keeps it clean and aids healing.
