AMAZING! See how exposure to blue light can help lower blood pressure

Latest research have shown that exposure to blue light can help lower a person’s blood pressure.

After 14 healthy men were exposed to blue light for just half-an-hour, their blood pressure levels were reduced just as much as with medication, a study found.

Blue light stimulates the release of nitric oxide, which relaxes blood vessels and therefore decreases blood pressure.

Researchers from the University of Surrey and Heinrich Heine University Dusseldorf exposed men all over their bodies to 450 nanometres of pure blue light for 30 minutes.

This is comparable to a daily dose of sunlight. Unlike UV rays, blue light does not cause cancer.

On a different day, the same men were exposed to blue light with a filter, which acted as the control.

The participants’ blood pressure, heart rates, blood flow and arterial stiffness were measured during the exposure and up to two hours later.

The study was published in the European Journal of Preventive Cardiology and carried out in collaboration with the electrical goods manufacturer Phillips.

‘Exposure to blue light provides an innovative method to precisely control blood pressure without drugs,’ study author Professor Christian Heiss, from the University of Surrey, said. ‘Wearable blue light sources could make continued exposure to light possible and practical.

‘This would be particularly helpful to those whose blood pressure is not easily controlled by medication, such as older people.’

Blood pressure medication’s side effects can include diarrhoea, dizziness, headache, nausea, vomiting and even erectile problems.
