Blood pressure latest studies claim that eating watermelons reduces high blood pressure in people who are overweight, drastically reducing their risk of a heart attack.
Scientists discovered that the fruit works to lower hypertension even when people are exposed to cold conditions.
Blood pressure rises in cold weather
It’s now been established that more people die of heart attacks in cold weather conditions due to the stress the body undergoes attempting to keep warm. The cold causes blood pressure to rise, forcing the heart to work harder, increasing the likelihood of having a stroke or heart attack. The research to support this was published in the American Journal of Hypertension, where researchers also reported that watermelon had a positive effect on health in terms of reducing heart problems even when subjects were exposed to cold conditions. Watermelon appears to decrease the pressure on the aorta and the heart.
Study involved overweight individuals with high blood pressure
The study looked at 13 men who were middle-aged and obese and 13 overweight women all of whom had high blood pressure. Over a period of 12 weeks, the participants’ hands were immersed in cold water in order to replicate cold weather conditions and stimulate the body to respond. Their blood pressure was measured while being exposed to the cold.
Each day, half the research group was given extracts of watermelon. The other half of the participants were given a placebo sample. Halfway through the study – participants switched roles.
What researchers found was that the watermelon acted to lower blood pressure and cardiac stress, even when participants were exposed to cold conditions. Professor Figueroa who led these blood pressure latest studies said that because of a reduced overload on the heart, the heart could work more easily during stressful situations – such as being exposed to cold weather.
Working out in warm water could help reduce blood pressure
This research comes hot on the heels of other blood pressure latest studies carried out at the University of Sao Paulo in Brazil, where it was found that working out in warm water could help reduce blood pressure. Researchers discovered that doing aqua-aerobics in warm water lowered blood pressure in subjects with high BP who had previously been found resistant to medications. Although it’s not entirely known why the warm water has this effect, it is believed that heat dilates the blood vessels thereby improving the flow of blood throughout the body.
Hot aerobics, as it is termed, should be carried out in water which is heated to around 32 degrees Celsius (most swimming pools are currently warmed to around 28 to 30 degrees). With so many people unresponsive to their blood pressure meds exercising in warm water could provide a natural and healthy way to bring down BP. This could be especially beneficial to those with arthritis and those who find it hard to exercise since the water puts less pressure on the joints.
RESPeRATE is the only non-drug therapy cleared by the FDA for the treatment of high blood pressure and the reduction of stress. It is the first medical device that has been clinically proven to lower blood pressure.
