Ageing is practice
during which physical and functional changes accumulate in an organism as a
result of the passage of time. The modifications manifest as a decline from the
organism’s peak fertility and biological functions until death.
In humans, ageing signifies the
accumulation of changes in a human being over time, including physical,
emotional, and social changes. The reaction time may slow with age, while knowledge
of world events and wisdom may increase. Ageing is among the extreme known risk
factors for most human diseases, about two
thirds die from age- related reasons. Ageing science includes Wrinkles, Female fertility declines, Hair
loss, Irregular Menopause, Hearing Loss,
Atherosclerosis, Heart Attack, Dementia, Alzheimer’s Disease, Memory Decline, Visual Impairment,
Risk factors for human Diseases, Age
related causes.
Daily
Blue-light exposure shortens lifespan: With the prevalent use of LED lighting
and device displays, humans are exposed to increasing amount of light in the
spectrum. Exposure to blue light comes from a variety of technologies
comprising televisions, computers, and lights. Much of the increased exposure
rises from light-emitting diodes (LEDs), artificial light is a risk issue for
sleep and circadian disorders. Since generally used LEDs emit a high fraction
of blue light, Blue light may affect human eyes and recent data suggest that
extraocular light may affect human brain physiology. However, the
significances of daily exposure to blue-enriched light across the lifespan are
not known.
“Wrinkles
should merely designate where the smiles have been.”
Effects of blue light technology:
Present academic and medical consensus
suggests there are no known health special effects of day-to-day. Blue light
sources are becoming progressively common in today's atmosphere. This is
frequently well-thought-out “the next generation of illumination” as
solid-state light (SSL) technology intensely reduces energy resource supplies.
Blue light effects on the circadian system and eye physiology. The gathering
experimental evidence has indicated that exposure to blue light can disturb
many physiologic functions, health effects and it can be used to treat
circadian and sleep dysfunctions. However, blue light can also encourage
photoreceptor damage.
High-energy
visible light:
HEV light has occasionally been claimed to be
a cause of age-related macular degeneration. Some sunglasses and beauty creams
definitely block HEV.
Life
extension:
Life extension is the idea of
encompassing the human lifespan, either modestly – through developments in
medicine – or dramatically by increasing the maximum lifespan. The ability to
accomplish such dramatic changes, however, does not currently exist.
Some researchers in this area, and
"immortalists", "life extensionists", or
"longevists" (those who wish to achieve longer lives themselves),
believe that future advances in tissue transformation, stem cells, regenerative
medicine, molecular repair, pharmaceuticals, gene therapy, and organ
replacement (such as with artificial organs or xenotransplantations) will
ultimately enable humans to have indefinite lifespans (agerasia) through
complete innovation to a healthy youthful condition..
The sale of claimed anti-aging products
such as supplements and hormone replacement is a well-paid global industry. For
example, the industry that promotes the use of hormones as a treatment for
consumers to relaxed or reverse the aging process the use of such products has
not been proven to be operative or harmless
