Stress, that is, mental pressure , has become an inevitable part of our lives, hasn't it? Problems at work, problems at home, exams... We struggle with all of these things every day. But have you ever thought that this mental stress is aging you from within your body, that is, at the cellular level? You may be a little scared after hearing this. But don't worry, because there is a very good side to this story. The latest scientific research has found that it is possible to reverse the rate of aging. Let's talk about this simply.
Can aging be reversed?
We used to think that aging was a one-way process, with no way to turn back. But a new study has found that this is not the case. Severe mental or physical stress, or trauma, can cause our bodies to age faster. However, once we recover from that stress, our bodies return to their normal age.
This is called biological age . It's not the age on your birth certificate, but how old and how worn out your body's cells actually are. As one of the scientists who conducted the study says, "We thought that biological age would increase directly with age. That's true, but there are ups and downs along the way. When there's stress, it accelerates, but the question is whether it stays there. We've now shown that's not the case, and that it can return to normal when the stress is gone."
How was this discovered? How to measure age with DNA
You might be wondering how you measure something like this. This uses a very advanced technology called DNA methylation clocks .
Simply put, over time, the DNA in our bodies forms certain marks. By looking at these marks, just like counting the rings on a tree, we can now measure the true age of our body's cells in days, even weeks.
One experiment that was done to confirm this is quite amazing. In it, an old mouse and a young mouse are surgically connected in such a way that their blood supply is exchanged. This method is called ``parabiosis``. After a few days, it is seen that the biological age of the young mouse has increased, and the age of the old mouse has decreased! Even more amazing is that when the two are separated again, the old young mouse returns to its normal age. This means that when the stress from the old blood is removed, the rate of aging returns to normal.
How does this happen in real life?
This has also been proven in human studies . You can easily understand how our body's biological age changes during various physical and mental stressors from the table below.
| Stressor | Impact on biological age |
|---|---|
| Emergency hip surgery, such as a hip fracture | Age increases dramatically within 24 hours of surgery. Recovery occurs within 4-7 days and returns to normal. |
| Pregnancy | Pregnancy is a stressful time for the body, which accelerates the aging process. However, it gradually returns to normal after childbirth. |
| Severe COVID-19 infection | Infection increases biological age. Although recovery occurs after recovery, women have been shown to recover faster than men . |
| Elective surgery | Because the body is prepared for it, it doesn't have as big an impact as emergency surgery. |
Not everyone recovers the same way.
The most important thing to understand is that not everyone recovers at the same rate after a stressor. Some people recover completely. Others only partially. Some people can't do it.
The reason for this is our resilience . That is, the strength we have to face and overcome a problem when it arises. The bodies of those who have this ability recover faster.
If you are constantly stressed out and thinking about something that you can't handle, your biological age will increase rapidly and you will be more likely to develop age-related diseases .
What hope do we have from this?
This discovery is truly a breakthrough in medical science. Another expert doctor who commented on this said, "Aging is not a continuous downward journey. It's more like a process of stopping and starting over."
The biggest message this research gives us is hope. Our bodies have an amazing ability to heal and recover.
We have much greater strength and resilience than we think.
This technology could be used in the future to see how effective anti-aging drugs are, and to help those suffering from conditions such as cancer and chronic diseases .
But remember, this isn't just about the little stresses of everyday life. But if you're experiencing long-term stress, or stress caused by a chronic illness, it's important to talk to your doctor about it. He or she can better understand your situation and provide you with the best solution.
Take-Home Message
- Severe mental or physical stress can accelerate biological aging at the cellular level of your body.
- The good news is that this is not permanent. Once you recover from the stress, this speed can return to normal.
- Our bodies have an amazing ability to recover from problems and recover (resilience).
- If you are suffering from long-term stress or a chronic illness, it is very important to talk to your doctor without being ashamed about it.
- Although this is still a developing scientific field, it could pave the way for new treatments to control aging in the future.
