This is Scientific Americans -60 seconds science .I'm Steve Murskey.Got the minute?
People with high blood pressure are often told to watch the salt, and it's long been far that hypertension related to excess salt is caused by the salt increasing in the volume of the blood, which in turn puts extra pressure on the blood vessel 1 walls . But going back to 1960s-70s some reseachers thought that the salt might be have a different effect. Now longtime hypertension researchers Arwin and Howerlong Scoumbers at the Boston university school of medicine have analysed the studies in the field of the published reviewal articles explaining what they think salt && really is.It stimulates 2 the sympathetic nervous system to produce a adrenalin,and it seems the adrenalin that construct the arteries 3 and caused the high blood pressure, not excess fluid volume .The reviews in the general hyperattention. Physicians have upsetted the nervous system involvement of the hypertension that's badly enough to cause kidney failure ,fluid decreacing diarect and sort of common treatment in those severe cases. It's new analyses that implies the researcher should look for additional hypertension treatments that focuses on the nervous system .
Thanks for the minute from Scientific Americans-60 seconds science. science being Steve Murskey.
