‘Silent killer’: New guidelines show 46% of US adults have high blood pressure

Doctors and experts from the American Heart Association, along with nine other groups, have bad news for 30 million Americans: they now have high blood pressure. This will bring the total number of US adults living with high blood pressure to 103 million.

The updated information indicates that high blood pressure (hypertension) will now affect nearly half of US adults, after the standards to diagnose the condition have been lowered from a threshold reading of 140 over 90 to 130 over 80, according to RT.

New insights into why sleep is good for our memory

Researchers have shed new light on sleep's vital role in helping us make the most of our memory.

Sleep, they show, helps us to use our memory in the most flexible and adaptable manner possible by strengthening new and old versions of the same memory to similar extents, according to Science Daily.

The researchers also demonstrate that when a memory is retrieved -- when we remember something -- it is updated with new information present at the time of remembering. The brain appears not to 'overwrite' the old version of the memory, but instead generates and stores multiple (new and old) versions of the same experience.

Lead researcher Dr Scott Cairney said: "Previous studies have shown sleep's importance for memory. Our research takes this a step further by demonstrating that sleep strengthens both old and new versions of an experience, helping us to use our memories adaptively.

Scientists discover those who eat too quickly are five-and-a-half times more likely than slow eaters to go on to develop a cluster of conditions

Bolting your food increases your risk of obesity, diabetes and heart disease, research suggests.

People who eat very quickly do not give their bodies time to realise it is full – meaning they tend to eat more according to Daily mail.

Eating slowly, savouring every mouthful and taking time over a meal is better for overall health.

A study of more than 1,000 middle-aged people found those who ate quickly were five-and-a-half times more likely than slow eaters to go on to develop metabolic syndrome - a cluster of conditions including obesity and high blood pressure, blood sugar and cholesterol.

Liver test to aid paracetamol overdose treatment

People who overdose on paracetamol could be helped by a blood test that shows immediately if they are going to suffer liver damage.

Researchers in Edinburgh and Liverpool said the test would help doctors identify which patients arriving in hospital need more intensive treatment, according to BBC.

The blood test detects levels of specific molecules in blood associated with liver damage.

Eye tests for Drivers should be compulsory

Drivers should have compulsory eye tests every 10 years, the Association of Optometrists has said.

One in three optometrists say they have seen patients in the last month who continue to drive with vision below the legal standard, their association said, according to BBC.

Motorists must read a number plate from 20m (65ft) in the practical driving test, but there is no follow-up check.
