Exclusive top-to-toe, inside-and-out tips on how to look and feel better

Skin
Teeth
Use an electric toothbrush, advises Dr Teresa Day, clinical director of Appledore Dental Clinic (www.appledore.co.uk). It removes more plaque and causes less damage: A manual brush used with a poor technique can cause gum recession and abrasion cavities in the teeth along the gum line, which can be extremely sensitive and difficult to fill.
Hair
Eyes
All contact lenses should be removed before sleeping (yes, even new-generation silicone hydrogel lenses), for cleaning and allowing oxygen to reach the cells in the eyes, warns Dr Iain Anderson, chairman of the Eyecare Trust in the UK (www.eyecaretrust.org.uk). Sleeping with lenses on increases the risk of eye infections, keratitis (inflammation of the cornea) and corneal abrasions, he adds.
Face
Arms
Tricep dips are the key to toned arms, says fitness expert Joanna Hall. Sit on the stairs and put your hands behind you on the step above. Your fingers should face forwards and your feet should rest on the floor. Now straighten your arms, lifting your bottom off the step and keeping your knees bent. Repeat 15 times.
Feet
Bones
Do 12-16 squats just before you go to bed. Pretending to sit in an imaginary chair is particularly beneficial for your hips, which are especially prone to fracture.
Swap cola for water: Heavy cola drinkers have up to 5.4 per cent lower bone density because the phosphoric acid contained in carbonated drinks affects the absorption of calcium. Yet, your body absorbs calcium just as well from mineral water as it does from milk, found a study in Osteoporosis International.
Stomach
Target abs by getting up from chairs without using your hands, says Judith Wills, author of Your Diet Questions Answered.
Sit on a wobble cushion (an inflatable cushion that creates an unstable seat) every day, says Helena Greenwood, a member of the British Osteopathic Association. Take it to work and use it at your desk or during your lunch hour or sit on it while eating an evening meal or watching TV. It stimulates your core muscles, tones your tummy, helps with balance and means you are doing your body good even when you're stationary.
A healthy gut is a precondition of beautiful skin, glossy hair and a flat stomach, says dietitian Pierre Pallardy, author of Gut Instinct. A key measure is to cut back on sugar, as it triggers excessive intestinal fermentation and leads to cellulite.
Eat more slowly: Food-bolters are more likely to overeat, say scientists from Imperial College London.
Back
Most of the time, it is bad posture that is responsible for round shoulders, double chins, fat bellies, flat bottoms and knock-knees. Dominic Cheetham of Sloane Square Chiropractors advises: Take the wall test. Stand with your back to a wall, with your bottom, your shoulders and the back of your head touching the wall for perfect posture. If not, adjust your position.
Switch to posture-saving messenger-style bags that can be worn across the body or the back. Your handbag should always weigh less than 8 per cent of your body weight, Cheetham warns.
