If there's one thing worse than bad weather at a summer music festival, it has to be bad health.

So if you're one of the millions of people who are heading to one - or more - of the UK's hundreds of festivals this year, pack your first aid kit as well as your waterproofs.

The obvious side-effects of over-indulging in alcohol and drugs may leave festival-goers feeling less than their best, but there are many ill effects that can spoil the party.

Neil Broadhurst, operations director for Events Medical Services, which provides medical cover for Latitude, says: "We get a wide range of all sorts - people get cuts, there's fainting because of dehydration, and vomiting and diarrhoea because people don't wash their hands properly."

As well as bumps, scrapes and dehydration, other common festival ailments are twisted ankles "because people don't look where they're going - they're gazing around looking at other things, like the bands".

Broadhurst says there are often very bad cases of sunburn. "Quite often, even if it's sunny, they'll go to the arena at the start of the day without putting suncream on, and they're out all day without thinking about it, until it starts to hurt much later."

Warm weather can also cause problems with insect bites for festival-goers, and such bites have been a particular nuisance at Latitude, which is held by a lake.

At the other end of the spectrum, wet weather can lead to cases of trench foot, which can occur when feet are wet for a long time, causing tingling, swelling and pain.

Broadhurst warns festival-goers to be prepared for the vagaries of the British weather, with sensible clothing, suncream and water, emphasising: "It's all common-sense things, but when people go to a festival they sometimes seem to throw common-sense out of the window."

FESTIVAL TIPS

t Don't trust the weatherman - This is England, prepare for rain at all times. It may be boring, but packing wellies and a raincoat can be a godsend.

t Get your bearings - Have a look around, especially where the best food stalls and toilets are, and have a meeting point in case you lose your mates. Mobile signals can be poor.

t Pick the right tent pitch - Avoid anywhere near the toilets, think of the smell. And its damp underfoot, it'll probably flood if it rains.

t Make your tent stand out - Will you be able to tell the difference between a thousands of identical green tents? In the dark?

t Travel light - No-one wants to be weighed down by piles of stuff, or fretting their best gadgets will be nicked from the tent. Take the essentials only.

t Don't wear your best gear - Your fantastic designer outfit may look great when you arrive, it won't when you leave - take our word for it. Cheap and worn in is best, with some funky festival accessories.

t Be open minded - The big name bands are obvious highlights, but the best times are often to be found in the quirkier more offbeat attractions.

t Have fun - The best festival experiences are when you go with the flow. Don't let petty niggles get you down and don't be a music snob.

FESTIVAL CHECK LIST

t Tickets - You'd be surprised how many people forget.

t Tent - Take one with room for two, you never know!

t Condoms - See above.

t Torch - Vital for finding the tent. Wind-up is best.

t Toothpaste, baby wipes and dry shampoo - It maybe a losing battle

but you'll want to preserve some semblance of personal hygiene.

t Toilet rolls - Tales of festival toilets are legendary, don't be a victim.

t Paracetamol - It may look shifty when you're taking them, particularly if you're sharing. But the reality is relief from a hangover rather than raving.

t Money - Daft as it may sound it has been known for festival-goers to forget. Who wants to spend the weekend begging?

t Camera - Disposable is best to avoid constant worry that it'll be trashed or nicked.

t Ear plugs - Sounds boring, but who wants to hear bleep techno at 5am?

t Sunblock - On the off chance the sun might shine.
