People who travel frequently on business or for pleasure often suffer some form of health

problem, yet over half of these problems can easily be prevented. The most common

ailment, a headache, can be avoided by taking along an ample supply of aspirin or other

pain reliever. Another common affliction is motion sickness caused by the constant

movement of a vehicle. Ginger capsules, sold in most health-food stores, have been

found effective as a remedy. Other familiar problems include sunburn, which can be

prevented by using an effective sunscreen, and insect bites, which can be controlled with

use of a repellent spray or ointment. For everyday cuts and scratches, a first-aid kit

containing bandages and antiseptic cream is recommended.
