Researchers have found that taking hot yoga classes lowered the blood pressure of adults with elevated or stage 1 hypertension.

While there is evidence of regular, room-temperature yoga’s positive effect on blood pressure, little is known about hot yoga’s potential impact on blood pressure, said researchers who presented the study at Hypertension 2019 Scientific Sessions in the US.

“The results of our study start the conversation that hot yoga could be feasible and effective in terms of reducing blood pressure without medication,” said study author Stacy Hunter, Assistant Professor at Texas State University.

Hot yoga is a modern practice, typically offered in a hot, humid atmosphere, with room temperatures around 105 degrees Fahrenheit.

For the study, the research team recruited 10 men and women, between ages 20-65 years. Participants had either elevated blood pressure (systolic blood pressure between 120 mmHg to 129 mmHg and diastolic pressure less than 80 mmHg) or stage 1 hypertension (130 mmHg to 139 mmHg systolic and 80 mmHg to 89 mmHg diastolic pressure.)

The research team randomly assigned five participants to take 12 weeks of three times-weekly hour-long hot yoga classes and they assigned the other five to a control group of no yoga classes.

They compared the average blood pressures of the two groups after the 12 weeks.

The researchers looked at average 24-hour blood pressure readings, as well as perceived stress and vascular function of participants in both groups.

They found systolic blood pressure dropped from an average 126 mmHg at the study’s start to 121 mmHg after 12 weeks of hot yoga.

Average diastolic pressure also decreased from 82 mmHg to 79 mmHg in the hot yoga group.

According to the study, average blood pressure did not change among the five adults in the control group, those who did not take hot yoga classes.

Perceived stress levels fell among those in the hot yoga group but not in the non-yoga group, the research said. (IANS)

Blood Test Can Identify Risk of Night-Time High Blood Pressure in People

Most people experience lower blood pressure at night

Researchers have found that a simple Blood Test can help identify people with obstructive sleep apnea (OSA) who are at higher risk of cardiovascular problems because of a phenomenon called “reverse dipping” that causes blood pressure to rise rather than lower during sleep.

Most people experience lower blood pressure at night. The new study, published in the European Respiratory Journal suggests a potential cause for reverse dipping that may help patients with sleep apnea get the help they need before cardiovascular disease develops.

“We can now identify those with OSA at the highest risk of cardiovascular problems in order to prevent them from developing additional complications,” said David Gozal from the University of Missouri School of Medicine in the US.

“We can treat those patients more aggressively to ensure they adhere to therapy and use their continuous positive airway pressure device (CPAP) properly,” Gozal said.

The researchers studied 46 patients diagnosed with OSA. They ranged in age from 18 to 70. Fifteen participants were identified to have a rise in blood pressure during sleep, while the remaining 31 participants had blood pressure readings that either remained the same or declined at night.

The researchers collected a blood sample from each participant to study the messages cells produce and send to each other through microscopic packages called exosomes.

“We found that the cell messages coming from participants with night-time elevated blood pressure were different than those transmitted in subjects with normal blood pressure,” Gozal said.

“The altered messages caused the cells that line the blood vessels to become dysfunctional. Those disturbed vessels allowed inflammatory cells to enter the vessels’ walls, causing hardening of those vessels and leading to cardiovascular disease.”
