How stress affects our DNA

It has been long documented that stress weakens the immune system and can make us ill. Now researchers think it has a major impact on our DNA.

Duke University Medical Centre, North Carolina have come up with the conclusion that stress stimulates the secretion of adrenaline, which if not controlled can interfere with our DNA.

Stress is not tangible, we cannot see it and nine times out of ten we don’t even know we are, we tend to think it’s others who are stressed. Many of us think that because we don’t discuss our issues associated with stress, then we can’t be stressed, but that’s not right. We can be stressed; we just don’t always know that we are.

We also hear people talk about efforts to control certain situations pertaining to stress. I think many of us now understand the results of what happens when we don’t manage to control the reactions, associated with stress.

So how does stress affect us? Well it affects everyone differently. We know that stress can cause heart disease but not many of us understand everything there is to know about the other physical and emotional problems that are induced, around stress and stressful situations.

The following may be of interest:

  • Around 43% of adults suffer with the adverse health effects brought about by stress;
  • Stress is linked to accidents; lung ailments; heart disease; cirrhosis of the liver, suicide and mental illness;
  • Between 75 to 90% percent of doctors’ visits are made because of stress related complaints and ailments.

To some extent stress is probably necessary, although too much of it can play havoc with our health and does. In society, stress isn’t easy to avoid it, but it’s important we get a grip on it. Not to handle stress is more detrimental in the longer term.

Stress is certainly a challenge, but one we’re all capable of handling and dealing with. We just need to know how to handle it.

  1. You are so right!

    Stress does have a detrimental affect on our health. It also affects diabetes. It can make your blood sugar go up. That’s my problem.

    It’s not what I eat, but my stress levels increase my blood sugar levels according to my doctor. My daughter suffers with self-induced stress daily. I hardly ever see her when she isn’t stressing about something.

    I can’t just tell her not to stress about things because she won’t listen to me when it comes to that. I do try to help her work through things so they are less stressful for her.

    I do believe though that stress does affect all aspects of our lives including down to our cells. Too bad we as a world can’t go back to the simpler times when things weren’t so complicated.

    1. I totally agree with you Lisa. If our lives were less complicated, that would = less stress. Hope your daughter controls her stress okay.
