your tooth’s enamel. Avoid chewing with the damaged tooth and use sugarless gum, wax, or a first-aid filling material called Cavit (available from dentists) to seal the tooth. You may have
to replace the covering several times a day. If there’s a lot of exposed pulp–and pain–you can cauterize the tissue with acetylsalicylic acid, aka aspirin. Break a pill into pieces
and hold one in place atop the nerve until the piece dissolves. It’ll be extremely painful for a minute, but that acid will kill nerve endings and you’ll be pain-free for 24 hours or more.
Repeat the process until you can get out of the woods, and get straight into a dentist’s chair. ”

throughout the day–while hiking and at rest stops. Wrinkled fabric can also contribute to the rub. Try going commando, or inching your underwear’s waistband up so it’s not
directly under the weight. Also, assess your pants. Are belt loops or seams positioned where your pack hits? You may be able to remove the loops yourself by cutting a few threads with your
knife or multitool scissors. If not, before your next trip, swap your pants out for a model that’s streamlined through the waist and hips.”

On hot days, tuck your GPS out of direct sunlight; on cold days, carry it in your coat to protect it from freezing (high-sensitivity receivers won’t lose reception). Also, try these
power-conserving tips to eke out at least a weekend trip from one set of cells.
>> Reduce trackpoint resolution to around 1 point per 1,000 feet or quarter of a mile.
>> Turn off your receiver where navigation is straightforward, and under heavy forest cover or in canyons, where it will waste power searching for an insufficient signal.
>> Reduce the backlight brightness and the timer for the display screen’s dimmer.
>> Disable power drains like the electronic barometer, altimeter, and compass if you’re not actively using them to find your way.”

hikes, you need to eat regularly to stay fueled and avoid bonking–no matter how small your appetite. Set a scheduled snack time for every 60 to 90 minutes of hiking, and eat at least 100
calories at each break. Supplement dehydrated foods with durable fresh ones that will be more appetizing and have a high water content (oranges, carrots, cucumbers). Eat salty foods like tortillas,
broth, and crackers to replace sodium lost through heavy sweating; reduce high-fat and high-protein foods like cheese, jerky, and nuts, which can speed dehydration (or eat them late in the evening).”

workouts. Also, protect against hot spots by applying a skin lubricant like Vaseline to high-friction areas–the balls of your feet and heels– before you start hiking, and by covering
problem areas with duct tape if you feel a hot spot forming. Optimize recovery by cleaning your feet and soaking them daily in cold water for at least 10 minutes. After that, elevate your feet and
stay off of them as much as possible between stages of your hike.”
