Suffering from low blood pressure? Do an hour or more of daily exercise and stay hydrated to improve the condition and control fainting or dizziness episodes, finds a NASA-funded study on astronauts.

The study is the first to examine the condition called “orthostatic intolerance” during daily activities when the astronauts returned home.

The researchers found that exercise regimens during space flight, followed by saline injections after landing, were sufficient to prevent the condition from occurring.

“Doing an hour or more of daily exercise was sufficient to prevent loss of heart muscle, and when it was combined with receiving hydration on their return, the condition was prevented entirely. We expected to see up to two-thirds of the space crew faint. Instead, no one fainted,” said cardiologist Dr Benjamin Levine from UT Southwestern Medical Center.

A similar condition is also diagnosed in patients as Postural Orthostatic Tachycardia Syndrome (POTS), which is predominantly found in women. The dizziness that it causes is life-changing and can be debilitating.

Dr Levine has helped one Dallas patient return to a normal life.

For the study, published in the journal Circulation, the researchers used a small blood pressure cuff on astronauts’ finger to measure blood pressure and every heartbeat.

These measurements were taken during multiple 24-hour periods before, during, and after six months of spaceflight. Twelve astronauts were involved — eight men and four women.

This treatment is just one of the ways medicine, heart research, and space travel have connected throughout Dr Levine’s work. The successful moon landing in 1969 was an early influence on his career.

The early interest led Dr Levine into space research within the field of cardiology, and he began working with the space shuttle programme in 1991.

“We put a catheter in an astronaut’s heart — it was former UT Southwestern faculty member Dr Drew Gaffney — and sent him into space. It was probably the most expensive right-heart catheterization ever,” Dr Levine reminisced.

“Much of our early research was devoted to understanding why astronauts faint when they return from space. Now, we can prevent it from happening”. (IANS)

With so many options available in the health, lifestyle fitness space, finding the one right for you can be a task.

Amaresh Ojha, CEO and Founder, Gympik shares his top tips.

1. Assess your fitness level- To assess your fitness progress, calculating the number of beats of your resting heart rate (RHR) is a beneficial way. The RHR should reduce as your fitness improves.

To calculate your RHR, place two fingers on your wrist (radial artery), and then count the number of heart beats you feel in a period of 60 seconds. Make sure to count the first beat as ezero’.

More than 101 is unusually high and not good. Between 81 and 100 is high, but acceptable, between 61 and 80 is average and 60 or less is good.

2. Choose what form of exercise works best for you- While any type of physical activity is beneficial for you, different physical activities present different results.

Yoga is a discipline that focuses on breathing methods, meditation, and physical postures. It has a low-impact structure and hence is gentler on the joints. Yoga helps in improving muscle endurance, flexibility and body balance.

Zumba is an amalgamation of both fast and slow dancing, so it works on your whole body, helping you to lose weight and tone every muscle group, predominantly your back and abdominals. It also improves your posture, balance and flexibility. So, if you wish to develop a flamboyant body shape along with enhancing your dance moves, Zumba will be the right choice for you. One concern with this exercise form is that the best result for Zumba comes while working out in groups, so you will have to join a Zumba class to get the best out of this exercise form.

Pilates is largely focused with core strength. It improves muscle tone and strength along with obtaining a leaner look. This exercise form promotes balanced muscle development, flexibility and helps you in gaining a beautiful posture. Hence, the gateway to a graceful personality is through regular Pilates workout. One disadvantage of this type of exercise form is that it misses out on cardio, so it’s not very effective for steady weight loss.

Walking is one of the best exercises that must be an integral part of your fitness schedule. Regular brisk walk can help in preventing heart diseases and managing high blood pressure and type 2 diabetes along with improving the mood. No matter how many hours you spend in the gym, walking is the best way to lose weight and stay healthy. This is one of the exercise forms that can be practised by all.

Cycling is an activity that is gentle on the joints. It burns fat and improves your cardiovascular health. If you wish to increase your stamina and at the same time tone up your muscles, cycling is the best way of doing so. You can easily make it a part of your routine by building it in your day as a means of transport.

3. E-Fitness learning platforms can help you analyse the pros and cons of any form of exercise and you can choose the correct type of exercise for yourself once you know the benefits of each type. There are several E-Fitness channels that you can subscribe to and work with a virtual instructor, who will guide you through your fitness journey.

4. Exercise safe and focus on the health concerns. Pre-exercise screening will help you to identify any medical conditions that may put you at a higher risk of enduring a health issue during physical activity. Consult with your doctor before incorporating a fitness routine in your lifestyle. Certain exercises like running on the treadmill, sprinting, heavy weightlifting etc. can prove injurious for heart patients. Similarly, certain breathing exercises in Yoga can prove harmful for asthmatic patients.

While there are several options available, the most important thing to keep in mind is to choose an exercise that you find fun and can stick to for the long haul. Choose from your preferences and make your exercise time fun. Do you wish to spend time indoors or outdoors? Alone or with friends/people?

If you choose an activity that seems like a burden after some time, you are more likely to abandon a healthy lifestyle. (IANS)
