There are a few important things you should always make sure you have with you before you travel - a passport, foreign currency and, if you're travelling in the EU, your European Health Insurance Card (EHIC).
But, do Brits really understand what carrying the EHIC entitles you to?

The truth is that plenty of Brits believe that carrying this little blue card is in fact just as good as taking out separate travel insurance, the Mirror reports.
This is where you begin to risk your safety while abroad, an explanation of the EHIC on the government website states: "An EHIC lets you get state healthcare in other EEA countries and Switzerland at a reduced cost or sometimes for free."
The site also clarifies that there has been 'no change to the rights and status of EU nationals in the UK, and UK nationals in the EU' as a result of Brexit.
While this means you are entitled to healthcare while travelling within the EU should you need it, you are only entitled to healthcare on the same level as locals in the country.
If you don't have travel insurance you will have to foot the cost of this bill yourself, and it won't be cheap.
When it comes to taking out travel insurance you need to ensure you are as transparent as possible with your insurance provider.
Failing to disclose a medical condition, any medication you take or any previous injuries could leave you with problems if you have to claim against them later.
Another thing to consider is whether or not you're planning on getting involved in any extreme sports while you're away.
Many travel insurance providers will have special sections to fill out for activities such as sky diving, white water rafting and other popular sports.
If you're worried that you aren't prepared for your trip abroad, go to the Foreign Office 'Travel Aware' page to find out all you need to know about staying safe and healthy abroad. You can apply for a new EHIC or to renew your current card here.
