Such questions have been discussed for many decades can science reverse and slow down aging or become immortal? and more things related to age?
Aging is a natural phenomenon, which affects every single living organism, and a natural change that begins in early adulthood.
Do you know – the human body is made up of 724 lakh crore cells, some of which cells start dying over time as we grow or old?
Then the body can not make new cells in proportion to it, this is what is called old age.
Old Age Issues
With increasing age, some common things can be seen and the risk of many diseases also increases including:
Some age-related changes can be seen such as:
- Sleep deprivation or less sleep
- The decline in senses and daily activity
- The skin gains to hang
- White hair is the most common age-related symptom, but in today white hair is seen in many youngsters, due to unhealthy lifestyles, or food.
- Low sex drive in both
- Panic or dying feeling at night
Old age is more prone to getting multiple diseases including:
- Heart diseases, attacks, stroke
- Increase the risk of infection
- The great risk of diabetes, high blood pressure
- Decreasing bone density with losing some height, which this bone is more prone to fracture, arthritis, etc.
- Joint pain
- Risk of many chronic diseases
- Difficulty in breathing, especially perform any task or asthma
Other issues that come with old age, which is different from country to country, In many developing countries old age, comes with the:
- Less financial support
- Specific diseases
- Live alone or in isolation, can lead to depression, and other mental issues
- Fear of being thrown out of home by children
Who Is More At Risk of Old Age?
There are some other factors that can increase the ageing process, due to which you look old at a young age are:
- Smoking and excessive alcohol consumption
- Certain foods unhealthy food such as – processed food, sugar, caffeine, fries, etc
- Lack of physical exercises
- Sleep loss
- Lack of sun exposure can increase the risk of wrinkles.
Old Theory In Ageing
Aging is a natural process, but until a few years ago, scientists could not understand what is the specific reason for aging.
However, there are some theories that say that ageing is already a prefeed process in our DNA.
But, the most reliable theory was to say, that it is caused by oxidation, free radicals, damage, and mutation In DNA.
Research on Slowing Down Ageing
In 2022, Dr. David Andrew Sinclair of Harvard University decoded the code of DNA, they say, the aging process is not caused by damage in DNA, but by defects in the Epigenome.
The epigenome is one of the main reasons for old age, you can understand it like this, the codes that are inside the epigenome are started removing as we old.
In simple – it is not the loss of DNA itself but the On or off switches on our DNA.
To prove this, Dr. David and his team experimented with 2 identical mice, which were equivalent to a 65-year-old human, but one is given a chemical compound called NMN.
The result, then it was seen that the rat who were treated with NMN ran on average 430 meters, compared to the other mice who ran 240 meters.
As the experiment progressed, it was seen that the one who was treated by NMN was running continuously for about 3 km, and that was an old mouse.
These NMN (nicotinamide mononucleotide) compounds increase and level in the body.
Dr. David and his team had tested NAD-boosting drugs on the elderly and hoping to get FDA-approved for the disease in the next 3 years.
Stem cell therapy may also play a vital role in aging therapy.
A 2019 research has shown that may aging therapy can help in future therapies to target the genetic basis of skin youthfulness aging.
However, there are some other things that can slow down aging, apart from NAD are:
Researchers on Reverse Aging Process?
In research conducted by Israel Chalabi University and Shamir medical center, during this, research, 35 people over 64 age (who did not have any serious illness) were included.
Those who were given pure oxygen by sent to a pressurized chamber for 90 minutes 5 days a week for 3 months.
The researcher’s claims were shocking saying that the age of these 35 people had stopped, while at the level of healthy cells, their body became equal to the youth of 25 years.
Its first effect was seen in chromosomes whose length stopped decreasing, also the number of inactive cells also started decreasing.
During this, the elderly were not given oxygen continuously for 90 minutes, but this process was also stopped in between.
The oxygen level in the body began to rise and fall, its effect was that in this struggle that started inside the body, these elders were young again.
There are only 1 or 2 researchers on this topic, there is more research needed.
During the research, 35 elderly people, 65 years were given pure oxygen 5 days a week for 3 months.
When the result was seen, it was found that aging has stopped in them, also the number of inactive cells also started decreasing.
In another research on slowing down aging, the results were quite positive when viewed on the rat.
