The worst case scenario for any trip would be an instance of traveller’s diarrhoea. This ailment can be brought about by reasons ranging from a change in environment, using unhygienic washrooms, not washing hands properly, drinking contaminated water, or eating raw/undercooked or unhygienically prepared food.
Prevention: Drink bottled water and eat freshly-cooked food. Eat fruits that can be peeled off, such as bananas. Carry a sanitiser at all times and wash hands frequently.
Flu can wreck a trip very quickly. Causes range from being exposed to crowded areas, and thus getting exposed to airborne diseases through sneezing and coughing, to coming in contact with the sick. Lack of hydration is another cause.
Prevention: Always cover your nose and mouth when in crowded places. Use an alcohol-based sanitiser. Drink enough water and eat light, boiled food. Try to get adequate rest.
The hills sure are calling, but so is mountain sickness. Oxygen levels at high altitudes are quite low, which not everyone is used to. Watch out for symptoms such as nausea, fatigue, dizziness and shortness of breath.
Prevention: Go slow while hiking, and remember to take breaks. This is important to let the body acclimatise. Make sure you are hydrated, and avoid alcohol. Take the prescribed medication.
If you travelling by road, you could have to sit—often cramped or slouched—for long periods of time. This could cause pain in the back or the neck, or legs cramps, and lack of blood circulation.
Prevention: Avoid pain and cramps while travelling, by ensuring you move around and stretch a little, every couple of hours. Pillows can be used to provide support to the back. While sleeping, use neck pillows.
Motion sickness is a common disorder where the inner ears and other senses are able to detect motion but your eyes aren’t. If looking out of a moving vehicle makes your head spin, and cause nausea, dizziness and headache, you may have motion sickness.
Prevention: When travelling by car, sit in the front. Eat light and take proper medication. Try to equalise your sensory cues by keeping your gaze fixed at a specific point.
