As a heatwave sweeps across the UK, whether on the train, in the office, the tube ride home, airports or bus stations, you might likely hear the muttering of ‘Oh it’s bloody hot’ or ‘this heat is unbearable’ or even ‘I think I may be melting’.

The world is getting hotter, temperatures in this hot spell are likely to peak at 39 degrees across the UK - and people are losing their minds.

But have you ever wondered what it is like for the British Armed Forces operating in some of the hottest parts of the planet and how they keep cool?

That includes everywhere from the jungles of Brunei to the British military’s training base in Kenya and Afghanistan - where temperatures can reach a whopping 50+ degrees.

Here are some of the measures, advice and tips that come with jungle operations.

Temperatures in the jungle can get extremely hot while wearing body armour, while carrying a weapon and kit, and, combined with the hostile terrain, this creates a very challenging environment.

Troops can sometimes only travel as little as a few hundreds metres a DAY before exhaustion kicks in and they have to stop.

After walking/cutting your way through just one hundred metres in the jungle, you become a very hot and sweaty mess.

One of the toughest jobs in the jungle is that of the Lead Scout - the person who finds/leads the groups track through the jungle.

They are usually the one who tires first, so ensure you routinely change the Lead Scout.

Due to excess sweating, the pores of your skin become blocked and the skin can no longer breath, so prickly heat becomes a real nightmare to manage.

If you have never had prickly heat, the only way to describe it is a nasty, tickling, itchy, burning sensation all over the body.

A simple trick to remedy prickly heat is to use medicated soap, coupled with an exfoliating glove to unblock the pores of the skin - you will have to ask your favourite oppo (mate) to get to all the hard to reach places.
