No matter what country you decide to visit, it will be important to have an itinerary of what you will need to take. If you plan on travelling to countries in Asia and Africa, it may be a lot harder to find items that would be easy to find at home, and when it comes to any medicinal and health products it will be highly recommended to take what you need with you.
Basic items such as toilet accessories may be easy to find, but any products such as painkillers should already be packed as there is a good chance you will not be able to get the same brand abroad. For anyone who has allergies to certain painkillers, it will be vital to bring a brand that that you are used to.
For travelling to hot countries, sun block should always be carried, especially if you are not used to high temperatures. Exposing yourself to direct sunlight without protection will mean that you are running the risk of heatstroke as well as causing damage to your skin.
Of course, the absolute travel necessities, such as passports and travel money, should never be left behind, and also well worth investing in is a secure money belt or a case that you are able to lock. Pickpockets are known to target tourist areas, as they know travellers will often be carrying cash and travel documents. If you do run into any problems, having a list of important telephone numbers for your home, airline, hotel and the local embassy will be indispensible.
