Is your iPod making you old? (And 6 other ageing enemies)

Feeling the effects of age? Forget smoking and sunbathing – there’s a new army of crinkle-culprits...

From niggling new aches and pains, to the wrinkle you're sure wasn't there yesterday, getting older is no fun. Fact.But we all know what ages us fast, right? No, it's not just a life of constant partying. Research has uncovered that culprits now include gadgets, health kicks, even 'miracle' creams.

"While genes play a role in how we age, lifestyle is a huge factor, too. Luckily, you can do something about that," says Dr Pixie McKenna from Channel 4's Embarrassing Bodies. Read on to find out what - then dust off your ID ready for the barman!

1: Ageing enemy:

Being so face fashionable

SJP protects her peepers with sunnies

Yep, we're always leaving our sunnies in the park/office/pub, too - but buying a cheap pair to compensate could be a false economy as far as your eyes are concerned. "Many fashion sunglasses don't filter out the harmful ultraviolet rays that speed up the growth of eye diseases like cataracts," says Boots optometrist Carolyn Zweig. Not to mention the wrinkles from all that squinting

This season's wraparound specs - à la Sarah Jessica Parker - are perfect as they protect against harmful rays coming in through the sides, too. "Look for ones that filter both of the harmful tanning rays - UVA and UVB," advises Carolyn.

At full volume, MP3 players can reach 120 decibels - the same volume as a jet engine!

2: Ageing enemy:

Teri's running could be adding on years

Celeb-style workouts

You dutifully pound the park every morning to get a Teri Hatcher-style figure - but you could be adding years to your face. "Women take up running in the hope it'll make them look slimmer and younger, but too much jogging can strain skin," says diet and movement specialist Joanna Hall (Joannahall.com). "The constant up and down motion pulls facial tissues, reducing elasticity and firmness."

Walk before you run! "Walking won't put your skin under the same pressure," says Joanna. Step out in a pair of new Reebok EasyTone Flip Flops, £45 (Reebok.com). Bouncy air pockets in the soles reduce the skin-sagging impact and improve muscle tone in your calves by up to 28 per cent.

3: Ageing enemy:

Your love of GaGa

Your quest to drown out fellow commuters with Poker Face puts you at risk of permanent and premature hearing damage. "In-ear headphones you get with MP3 players aren't always great quality, so you crank up the volume - but this can permanently damage hearing after 15 minutes," warns Emma Harrison of the Royal National Institute for Deaf People (RNID). Experts are calling for the maximum volume setting to be 85 decibels.

"Invest in a pair of noise-cancelling headphones (available at Rnid.org.uk), which remove background sound so you don't need to turn the volume up as loud," recommends Emma. If you're worried about your hearing, take the RNID's online hearing check on its website to rate your ability to hear with background noise.

4: Ageing enemy:

Your gloomy outlook

Always double-checking you've been given the right change? Or likely to eye up your friend with a look of doubt when she offers you a compliment? It's time to loosen up, because not trusting people knocks years off your life expectancy. "Research shows that people who don't assume everyone's out to get them will live longer," says Phillip Hodson of the British Association for Counselling and Psychotherapy (Bacp.co.uk). "By always being on guard, your body pumps stress hormones like adrenaline into your system to keep you alert, and this can take its toll on your heart. It's like constantly revving your engine and it will wear out."

Let your guard down. "If you're speaking to someone new, ask them lots of questions about their life," says Phillip. "This will shift the emphasis from you, so you won't feel defensive and suspicious."

5: Ageing enemy:

Crash dieting

Think ditching a couple of pounds will help you look younger? Have we got news for you. Research by Harley Street plastic surgeon Rajiv Grover found that the strain put on your body from crash dieting can cause an ageing spurt on your face. "Ditching meat, fish and eggs, which lots of dieters tend to do, can thin hair and make skin look old before its time," says Dr Pixie. "That's because they contain cell-boosting iron, which makes haemoglobin to carry oxygen to cells, and vitamin B12, a great cell regenerator. These are both essential for healthy skin and hair."

Ditch the 3pm chocolate fix. Sugar causes a process called glycation, where pesky sugar molecules attach to protein molecules (such as collagen, which is essential for plump, pert skin) and destroy them. The result is wrinkly, saggy skin. Nice.

6: Ageing enemy:

Making sex-cuses

OK, so we're not saying you need the sex drive of a Premiership footballer - but saying no to nookie could take its toll on your complexion. New research by Dr David Weeks, a neuropsychologist at Royal Edinburgh Hospital, has found that couples who are at it at least three times a week look around a decade younger than those who have sex less often. "Sex releases endorphins, which improves circulation to your skin and boosts your immune system - making you look younger and helping you to live longer," confirms Dr Pixie.

Get wed! If you're married this could lengthen your life expectancy by five years - experts believe the security of a relationship makes people less stressed.

7: Ageing enemy:

Your designer moisturiser

Many moisturisers contain sunscreen to protect against the ageing effects of UV rays - but cutting out the sun can age you, too.

"We need sunshine to make vitamin D, which protects us from certain illnesses. Not getting enough could make you prone to ones linked to old age, such as brittle bones," explains Dr David Grimes, a consultant physician at Royal Blackburn Hospital. "Be careful, but try to get five to 10 minutes a day in summer without wearing sunscreen."

Keep wrinkles at bay with the new Slendertone Face (£300, Slendertone.com), which emits pulses of electric current that tone droopy face muscles. After 12 weeks, 94 per cent of testers had firmer skin*.
