Can’t sleep? Try eating more rice: High GI food increases levels of protein used to make serotonin, known to induce sleep

The more rice participants ate, the better they rated the quality of their sleep

Have
trouble nodding off? Eating rice could help, suggests new research. In a
study of nearly 2,000 people, the more rice they ate, the better they
rated the quality of their sleep.

Researchers also compared how much bread or noodles were consumed, but the same link was not found.

Just
how it works is not clear, but rice has a high glycaemic index or GI – a
measure of how quickly carbohydrates are broken down into sugar in the
blood. High GI foods increase levels of a protein called tryptophan that
is used by the body to make the brain chemical serotonin, which is
known to induce sleep.

Bread and noodles have a lower GI, which may be the key, concluded the researchers from Kanazawa Medical University, Japan.

Clip on nose filter to beat hay fever

A clip-on nose filter promises to block hay fever symptoms before they start.

The
new device, made from thin, flexible plastic, clips onto the fleshy
part between the nostrils. Two fine nets on either side of the clip
cover the opening to the nostrils and stop pollen getting into the nose.

The Rhinix filters are on trial at Aarhus University, Denmark, with 1,500 patients.

An
earlier study, which compared the filters with a placebo, suggests they
can reduce hay fever symptoms such as sneezing, a runny nose, and an
itchy nose and throat. Manufacturers say the filter has no effect on the
wearer’s breathing. 

Hay fever treatments such as antihistamine
tablets counter the effects of the allergy once the pollen has already
entered the body, by blocking the action of the chemical histamine,
which the body releases when it thinks it is under attack.

Asthma can make it hard to conceive

It took women with asthma 21.6 per cent longer to conceive compared with those without

Women with asthma find it more difficult to get pregnant, according to a Danish  study that analysed data from 15,250 women.

Overall,
it took women with asthma 21.6 per cent longer to conceive compared
with those without asthma, with 27 per cent of the asthmatics taking
more than a year to get pregnant. The delay was more pronounced in women
whose asthma was poorly controlled.

‘Our assumption is that asthma
in the lower airways can simultaneously cause inflammation in the womb
which, if not treated correctly, can inhibit normal implantation of the
fertilised eggs,’ say the researchers from Bispebjerg University
Hospital.

Asthma causes the airways in the lungs to become inflamed
and over-sensitive, so they narrow when in contact with a trigger,
causing breathlessness, wheezing and a tight chest.
