Doctors tend not to be concerned about low blood pressure until diastolic pressure falls below this level. Our data indicate that even individuals with diastolic blood pressures well above this 60mmHg threshold are unable to support normal cognitive function when upright. Indeed, at essentially any resting diastolic blood pressure below normal 80mmHg , the trend in the data indicates that cognitive performance in older adults is significantly reduced. Interestingly, these results are consistent with earlier reports of detrimental influences of low blood pressure on cognitive function even in young adults.
Low diastolic pressure can arise as a result of medication use, heart failure or other health complications. But, in most people, it is simply a matter of the heart not pumping out enough blood with each stroke; in other words, low cardiac output. And low cardiac output occurs when not enough blood is being returned to the heart from the lower body. The soleus muscles, specialized muscles in the middle of your lower legs, are responsible for pumping blood back up to the heart. Over the last decade, our research team has demonstrated how the soleus muscles plays a critical role in maintaining normal blood pressure during sedentary activities.
These deep postural muscles are most active during activities such as sustained squatting or toe standing.
What is blood pressure?
You can rebuild these muscles by regularly undertaking such activities, though it requires hours a day of exercise. Both electrical and mechanical , soleus stimulation approaches have been shown to significantly increase venous return to the heart. Preliminary clinical studies have also provided confirming evidence that raising resting diastolic blood pressure through daily soleus muscle stimulation, over a period of several months, can reverse the cognitive impairment associated with aging.
No treatments currently exist for dementia, and no potential treatment seems to be on the horizon, and so the health care community has become much more focused on slowing, or reversing, cognitive aging to prevent progression to dementia. If interventions to eliminate chronically low diastolic blood pressure are simple and direct, we may well have the opportunity to largely eliminate much of the scourge of dementia from modern life.

UEA Inaugural lecture: Alternative performance measures: do managers disclose them to inform us, or to mislead us? It depends on the time of day, the amount of fluid in your body, the medicines in your system and what you are doing. Your blood pressure can also be affected by things like your breathing, your emotions, exercise and sleep. These temporary rises are completely natural and your blood pressure will generally return to normal when you rest. The exact cause of high blood pressure is often not clear. However, various lifestyle conditions and behaviours have been known to significantly contribute to high blood pressure:.
The good news is you can control and even help prevent high blood pressure by making healthy lifestyle choices. These include:. Sometimes changes in your lifestyle alone may not be enough. Many people will also need medication to help reduce their blood pressure.
If you need to take medication to lower your blood pressure your doctor will discuss this with you. You should ask your doctor to check your blood pressure regularly. This is the misleading use of percentage change instead of actual change. Second, the participants were already at higher than average risk for cardiovascular problems, so it was a study of a selected group and not of the general population.
This may seem small, but the translation is not small when applied to real world people.
In the context of many other things we do in our life medical treatment or not , this is really good! For example, did you know it takes 10, mammograms done yearly for 10 years, in order to just prevent 10 breast cancer deaths? It really scares me, I know that I can have a stroke or heart attack.

I think at this point any restaurant or food industry that adds excessive salt should be taxed commensurately to help defray the cost for health care. The salt is killing us.

I travel extensively, and our country by far uses too much salt in processed and restaurant food. Perhaps you can can help educate people and force the food industry to change! One can only hope. Give me a break.

I agree. Eating at home is the only sure way to keep your bp down. Way too much salt in restaurant meals. Excellent point! And, of course, there is just plain bad luck or fate, finger of God, however you choose to describe it.
