Anti-ageing, any real evidence?

Anti-ageing, any real evidence?

Here are some interesting facts to keep you up-to-date on some anti-ageing agents:

DHEA: (Dehydroepiandrosterone) is a steroid secreted byrepparttar adrenal cortex. This hormone isrepparttar 115878 precursor for testosterone, progesterone and estrogen. This hormone is found to decline with age so replacing this hormone could be expected to slow age-related changes. DHEA has also been shown to be directly related to mortality with an inverse relationship existing betweenrepparttar 115879 levels of DHEA and mortality from heart disease as well as other causes1. Calorie deprivation (known to prolong ageing, see below) is also known to inhibitrepparttar 115880 decline of DHEA. Another important hormone with antiageing properties include HGH (human growth hormone). Effective HGH hormone sprays are available.

Antioxidants: The theory is that in ageing unrepaired oxidative damage accumulate puttingrepparttar 115881 organism under increased stress. DNA damage is also reported to be associated with oxidative stress. Antioxidants protect against cellular damage by mopping uprepparttar 115882 reactive oxygen species that cause damage. A recent study2 of elderly subjects found that DNA damage occurred in 45 % of subjects, with 62% having low total antioxidant levels. Antioxidants include vitamins C, A, E, andrepparttar 115883 mineral selenium. Although these agents are effective antioxidants, their beneficial effects in slowing ageing still remains largely unproven. There is considered stronger evidence forrepparttar 115884 roles of these antioxidants in degenerative disease such as atherosclerosis. The area of antioxidants in ageing is still an active area of research interest. Tip: not many people know, but there is an effective and convenient test for checking your Antioxidant status to see if you are adequately protected againstrepparttar 115885 damaging effects of free radicals. The test involves measurement of lipid peroxides in urine. Lipid peroxides represent damage caused to fats by free radicals and provide a useful barometer of your antioxidant status.

The Need for Silence in a Noisy World

The Need for Silence in a Noisy World By Mike Moore

It is quite evident that we are living in one terribly noisy world and it seems to be getting worse every day. Everywhere we go we are accosted by loud, unwanted sound. When we enter elevators, malls and restaurants we are engulfed by musak. I recently had lunch at a popular restaurant and foundrepparttar background music so loud that it interfered with normal conversation andrepparttar 115877 enjoyment of my lunch. When I askedrepparttar 115878 waitress if she could turnrepparttar 115879 music off, or at least down, she said, " I don't think we can." Surely we as a people are still in charge of volume controls.

When you add lawnmowers, snow blowers, leaf blowers, jack hammers, jet engines, transport trucks, and horns and buzzers of all types and descriptions you have a wall of constant noise and irritation. Even when watching a television program at a reasonable volume level you are blown out of your chair when a commercial comes on atrepparttar 115880 decibel level of a jet.

We seem to have created a cultural acceptance of our noisy world in spite ofrepparttar 115881 fact that it is making us ill physically and psychologically. We can't seem to live without background sound. We have friends who turn onrepparttar 115882 televisionrepparttar 115883 moment they awaken inrepparttar 115884 morning and leave it on all day. The house is just too quiet if it isn't on. Former highschool students of mine used to tell me thatrepparttar 115885 first thing they did on arriving home after school was turn on their CD player as loudly as would be tolerated by their parents.

Cornell University recently conducted a study to determinerepparttar 115886 impact of noise on employees in an open area office space where people are constantly exposed to fax machines, telephones, office chatter, shredding machines, etc. Test results revealed that workers in an open area had high levels of adrenalin in their urine. Adrenalin is released byrepparttar 115887 body when under stress. It prepares us for fight or flight. When these employees were compared to those in self contained office spacesrepparttar 115888 results were startling. People in a quiet, self contained work area did not haverepparttar 115889 same high levels of adrenalin in their urine. They were much more relaxed and less stressed.

A puzzle, demanding attention and concentration, was given to both groups of employees. The open area group was found to be less diligent inrepparttar 115890 solution ofrepparttar 115891 puzzle becoming easily frustrated and giving up much earlier thanrepparttar 115892 group fromrepparttar 115893 quiet office. The study also found that workers fromrepparttar 115894 quiet office slept better at night, had better digestion, were much less irritable at home and felt better atrepparttar 115895 end of their workday than employees fromrepparttar 115896 open concept office. Noise does seem to effect focus, productivity and general physical and psychological well being. Noise tends to increase stress levels which in turn can result in increased frustration, anger and strained interpersonal relationships. We must begin to establish a friendship with silence.
