Do they suffer from low blood pressure? Make an hour or more of everyday exercises and stay hydrated to improve the condition and control of fainting or dizziness, a NASA-funded study found on astronauts.

The study was the first to examine a condition called "orthostatic intolerance" during everyday activities when astronauts returned home.

The researchers found that exercise regimes during the space flight, followed by saline injection after landing, were sufficient to prevent the onset of the condition.

"To make an hour or more of everyday exercises was enough to prevent the loss of the heart muscle and when combined with obtaining hydration at their return, the situation was completely stopped. We were expecting to see up to two-thirds of the space team instead that no one has fainted, "said Dr. Benjamin Levin of the Southwestern Southwestern Medical Center.

A similar condition has been diagnosed in patients such as postural orthostatic tachycardia (POTS) syndrome, which is mainly found in women. The dizziness it causes is a change in life and can be debilitating.

Dr Levin helped a patient in Dallas to return to a normal life.

For the study, published in the Circulation Journal, the researchers used a cuff for blood pressure on the astronaut's fingers to measure blood pressure and every heartbeat.

These measurements were taken during the multiple 24-hour period before, during and after six months of the spacecraft. Twelve astronauts were involved – eight men and four women.

This treatment is just one of the ways in which medicine, heart research, and space travel are linked during Dr. Levin's work. The successful landing of the moon in 1969 was an early influence on his career.

Early interests led Dr. Levin to enter space research in the field of cardiology, and he began working with the space shuttle program in 1991.

"We put a catheter at the heart of the astronaut – it was the former member of the Yuthoron faculty, Dr. Drew Gaffney, and sent it into space. It is probably the most expensive catheterization of the right heart," said Dr Levin.

"Much of our early research was dedicated to understanding why astronauts are poorly returning from space, and now we can prevent it from happening."
