1. Do I Need to Drive 8 Glasses of Water Every Day? Water acts as a lubricant in the body and we can’t live without it. It helps circulation and digestion and is part of the body’s filtration system, helping the kidneys to function. It helps temperature control in the body and provides fluid in the joints to cushion your bones. You DON’t need 8 glasses of water a day – its overkill. You must remember to take into account that if you already get a large percentage of water from your food or drinks such as tea or coffee and then drink eight glasses on top of that, you are drinking more than you need and the kidneys will just get rid of it as waste. It doesn’t make you beautiful as the film stars would have you believe. Your body needs about 3 litres of water a day and should vary depending how much exercise you are doing. If for instance you are running a marathon, then 3 litres does not apply. Remember that sugar drinks can dehydrate you and that water is the best way to rehydrate your body.
2. Is 8 Hours the Magic Number for Sleep? YES eight hours is the recommended amount of sleep to allow us to be able to rejuvenate and heal the body. Anywhere between seven and nine hours is also good. If you sleep less, then the key is to try and catch up the next night. 3. Can Vitamins be Dangerous? YES while many are water-soluble and the excess is flushed out of the body, some minerals and fat-soluble vitamins such as A, D and E can build up to dangerously high levels in the body if taken in excess of the recommended daily allowances (RDAs). If you are a healthy person and have a normal, healthy diet, you won’t need to supplement with multivitamins because your healthy diet should contain everything you need. There are some exceptions such as menopausal women and vegetarians. “VITAMIN ALERT” - Large doses of iron can be fatal in children. In adults it can cause nausea, constipation and stomach pain.
- Vitamin B in large amounts can produce nerve tingling in the feet and legs and can be sometimes irreversible.
- Vitamin A in large amounts can accelerate osteoporosis and cause birth defects in unborn babies.
- Vitamin E in large amounts can increase your chance of a heart attack.
- Large doses of beta carotene (equivalent to six carrots a day) have been found to increase the risk of lung cancer among smokers.
4. Can You be Fat and Fit? If you are skinny, that does not make you fit and if you are a little bit heavier, that doesn’t make you unfit. Fat people can be fit - a leading authority on exercise and obesity epidemiologist in America who conducts numerous studies at the Cooper Institute for Aerobic Research in Texas says: Fitness and fat are different things. Some football players have guts but can run up and down the field a lot longer than somebody who weights a lot less. Of course Dr Andrew and other health experts agree that carrying excess weight is not good for our health and being overweight is a risk factor for everything from heart disease and diabetes to renal problems and blood pressure. People who are overweight run a risk of a lot more health problems. 5. Should I Take an Asprin a Day? Asprin is a very good drug for people who are at risk of heart disease and strokes but it is not something that everyone should take. Asprin should be prescribed by your doctor for your own health as it can also cause inflammation in the stomach and occasionally stomach ulcers which may bleed. 6. Why Are Kids More Allergic These Days? The theory is that kids are not exposed to as many allergens today because society is more afraid of dirt, germs and bugs. So ultimately, their immune system does not get the chace to recognise these things and subsequently they tend to have more of an allergic reaction to them. |
