Nighttime Noise Could Possibly Raise Blood Pressure Risk

We’ve long known that some people are light sleepers while others snooze right through extremely loud noises. Though fairly small, a new study shed some interesting light on how sleeping in noisy areas may affect your body. According to this study, your sleeping body registers the effects of noise by temporarily raising your blood pressure. The study monitored a group of volunteers who lived near four busy European airports hosting plenty of inbound and outbound flights every night. Each participant was fitted with a blood pressure monitoring device, which was programmed to gather blood pressure info at 15-minute intervals. To complete their preparations, researchers outfitted each volunteer’s bedroom with a sound recorder and a decibel meter. This allowed the researchers to record all background noise entering the room, along with time and volume indicators.

Astonishingly, researchers found that noise events correlated precisely with spikes in subjects’ blood pressure. These findings covered all types of noise events, from airport noise to traffic sounds or snoring. As one might reasonably expect, researchers noted that louder sound events corresponded with more pronounced spikes in blood pressure. Though most people intuitively realize that it is better to sleep without interruption, it is more surprising to learn that noises can affect your body even as you remain fully unconscious. For people who suffer from abnormally high blood pressure and heart disease at the same time, this topic is naturally of great interest.

Nevertheless, it is too early to draw too many conclusions from this study. Although this study is a step forward, researchers still don’t completely understand the relationship between noise and hypertension. Co-authored by Dr. Jarup of Imperial College London, this recent study only featured 140 study subjects. It may take a much larger study to produce definitive answers regarding this important topic. It is interesting to contrast this study with an earlier sleep study from the same organization. The earlier study monitored a much larger group, which numbered in the thousands. In the previous study, researchers found that regular exposure to night-time highway noise increased hypertension risk for men. However, this effect did not extend to women. Mysterious results like these demonstrate that we have a lot to learn about the human body.

Fortunately, high-quality foam earplugs help a lot when it comes to reducing night noise. To achieve quieter sleep without cutting yourself off from the world, consider wearing one earplug when you retire. This will significantly reduce your noise exposure without leaving you totally unresponsive to stimuli. Remember that there is more than one way to put in an earplug. You’ll want to use a method that ensures a tight seal in your ear cavity. If your foam earplugs fall out of your ear routinely while you sleep, there’s a good chance you’re not putting them in properly.


Does Yogurt Help Lower Blood Pressure?

Exercising, eating more vegetables and cutting out fats are all time-tested solutions to lowering blood pressure. This cardiovascular measurement is incredibly important because it tells doctors whether your arteries and heart are working normally or too hard. Ideally, your blood pressure should be about 120/80 mmhg. To achieve this value, you must pursue a healthy lifestyle and may require some prescription pills. New evidence suggests, however, that yogurt can actually help your blood-pressure values.

Yogurt’s Good Bacteria

A major reason why researchers believe that yogurt is helpful to your blood pressure is the indirect benefits that are already proven. Yogurt contains active cultures, which are considered good bacteria. As you consume this creamy treat, the body uses the bacteria to boost the immune system and improve the digestive tract. Because these two systems have a boost, your heart doesn’t have to work very hard to maintain homeostasis. As a result, low blood pressure occurs.

A Caveat to Yogurt’s Role

It’s important to note that yogurt’s effects on the body cannot compete with poor eating habits. Researchers note that an improved blood-pressure value with yogurt consumption is only possible when a healthy diet is followed. In particular, the DASH diet for people with hypertension tends to be the most influential. Lean meats, dairy, fruits and vegetables all work in harmony to lower cardiovascular stress.

The BMI Influence

Yogurt helps people with hypertension when their BMI or body mass index is normal or approaching normal. Eating a DASH diet with yogurt means that a person is maintaining a healthy lifestyle. People normally lose weight with this lifestyle choice. When an overweight person eats yogurt, the cardiovascular effects may not be that significant. It’s important to lose some weight so that the dairy products can shine through at the cardiovascular level.

To keep an accurate account of your blood pressure, purchase a personalized system from a local drugstore. These devices encourage you to record the values several times a week. If you try to eat yogurt on a regular basis, you might see the results that researchers are currently discovering. In the end, there’s almost no drawbacks to eating more yogurt. You’ll simply have stronger bones, reliable cardiovascular functions and a comfortable digestive system as a result.
