Many Americans live with high blood pressure every day; It affects one in three adults in the country. There are easy steps you can take to prevent high blood pressure or keep it under control. Doctors often suggest a healthy diet and plenty of exercise to combat high blood pressure. But new research suggests that exposure to certain lighting can have a positive impact on hypertension.
High blood pressure can cause serious heart problems
When you have high blood pressure, it means that the pressure between the blood cells and the arteries is greater than it should be. It can be genetic or caused by a poor diet and a low level of exercise. When the blood becomes more difficult to pass through the arteries, the arterial walls try to compensate for the difference. They begin to thicken to send blood through. But if they get too thick, they cause a blockage. Depending on where the blockage occurs, it can cause a heart attack or stroke. That’s why it’s incredibly important to control your blood pressure levels; especially as you get older. They can also have other serious effects on the body, such as eye diseases that can leave you with permanent vision loss.
A study suggests that exposure to blue light can lower blood pressure
One study found that exposure to blue light, which does not emit harmful ultraviolet rays, could have a positive effect on blood pressure. The study was published in the European Journal of Preventive Cardiology and exposed participants to 30 minutes of full-body blue light. On a different day, the test subjects were exposed to controlled light. The researchers evaluated the effects by measuring patients’ blood pressure, stiffening of arteries, dilation of blood vessels and blood plasma levels of nitric oxide stores, Science Daily reported. Levels were measured before and during exposure, as well as two hours later.
The researchers found that systolic blood pressure dropped almost 8 mmHg after exposure to blue light, meaning that patient levels were significantly lower. The controlled light showed no changes in blood pressure levels. Researchers believe that blue light is absorbed through the skin and relaxes blood vessels, resulting in a general drop in blood pressure.
Two easy ways to lower blood pressure are naturally through diet and exercise.
While blue light as a way to control blood pressure is a breakthrough, it is not as convenient as changing your diet and exercising daily. It is better to eat foods low in sodium, since sodium causes the blood cells to retain water. This makes the blood more difficult to pass through the arteries, thickening the walls of the arteries and raising blood pressure. Daily exercise is also important for the heart to function well. The American Heart Association suggests doing approximately 150 minutes per week of moderate exercise, or 75 minutes per week of rigorous exercise. It is the best way to ensure that your heart stays healthy. And when combined with a healthy diet, it can help add years to your life.
