7 Main Practical Applications For Light In Survival Situations
Humans equate light with safety, and for good reason
. When a person is stranded in an emergency situation, a light source can mean the difference between life and death. They say that humans need food, water, shelter and fire to survive; a sense of hope also comes in handy.
Light sources such as lanterns and flashlights can help those in survival situations arrange everything they need to survive. The following is a look at why light is important in emergency survival situations.
Here are some of the many practical uses for light in a survival situation:
Gathering materials. If you become lost and night is falling, an LED flashlight can allow you to locate brush that may used to build shelter. Headlamps and lanterns can also help you gather sustenance. (To avoid poisoning themselves, those who put themselves in potential survival situations should study which local plants are edible.)
Signaling search parties. Survival manuals always dictate that you tell a couple of trusted friends or family members about where in the backcountry you are headed and when you expect to return. This ensures that someone will eventually come looking for you if you become lost or injured. Light sources such as flares, headlamps and an LED flashlight can be used to signal passing planes and search parties.
Building a campfire. Fire is essential in wilderness emergency situations. The warmth of a campfire staves off frostbite and hypothermia. An LED flashlight or headlamp comes in handy when building a campfire at night. (It's not unusual to realize that you'll be spending a night in the wilderness until darkness has nearly fallen.) Gathering around a campfire can also lift a person's spirit and provide a sense of safety.
Maintaining high spirits. In any situation, a person's psychology impacts his or her overall health. Feelings of anxiety and stress lead to an increased heart rate, higher blood pressure and an inability to focus. When we're scared and panicky, our bodies enter "flight, fight, or freeze" mode, and we are less able to properly think through the implications and opportunities of our current situation. (Indeed, in this amped-up emergency mode, the portion of the brain responsible for higher-level decision-making actually turns off so that more energy may be spent on lower-level survival brain functions.)
Because the body and mind are so intricately linked, those who quickly give up and tend toward self-pity are less likely to survive. Military veterans can vouch that in emergency situations, some people have a hard time surviving even with plenty of resources, while others seem to require little more than the clothes on their back to fight on. Light makes humans feel safe and protected. Having an LED flashlight on hand can help give survivalists the optimism they need to calm down and focus on the tasks at hand.
Food preparation. Even if you're just car camping, it's smart to bring along an LED flashlight or a couple of headlamps for those in your party who will be setting up camp. Unexpected circumstances could arise that would put you at your destination later than you expected. If you find yourself preparing food in the dark, headlamps and lanterns can help you prepare healthy, delicious food.
When nature calls at night. Leaving the comfort of camp to relieve one's bladder can be frightening. Having an LED headlamp can make it far easier to head off for that nighttime bathroom break.
Stave and scare off wild animals. An LED flashlight can help keep a safe distance between you and any wild animals in the area. Whenever you're walking in the wilderness at night, it's best to carry illuminated headlamps, lanterns, or flashlights, which will warn off animals. If you happen to unexpectedly cross paths with an animal, there's a good chance that the light from your LED flashlight or headlamp will scare it off.
As you can see, having an LED flashlight or another source of light can make a big difference in emergency situations. Lanterns, headlamps and flashlights with LED bulbs are often considered superior in emergency situations, since LED bulbs are extremely long lasting and efficient. One LED bulb may last for tens of thousands of hours - an extremely comforting thought when spending a night alone in the wilderness.
