A new study from the University of Oxford found that around 15 percent of people aged 40-75 may have undiagnosed hypertension.
Those who may be suffering from the form of high blood pressure may not know, as pressure spikes at night. This could put them at increased risk of cardiovascular diseases including stroke and heart failure.
The researchers have said that 24-hour blood-pressure monitoring has become less frequent since the Covid-19 pandemic began. They also point out that home blood-pressure monitors cannot be used during sleep, meaning that those who spike at night could go undiagnosed.
