A new research reveals that a single weekend
camping trip can help people reset their body clock and get to sleep earlier.
The idea is to stay a few days outdoors and away from artificial
lights.The research team is working on the connection between natural and artificial
light and sleep patterns. Circadian rhythm is a natural 24-hour cycle
of physical and mental changes happening in the body.
Researchers found out that electric lighting
can disrupt that pattern by as much as two and a half hours. This can delay the
sleep pattern as well.When the researchers sent a group of eight people on a
camping trip during the summer for a week, they found exciting results.
The night owls turned into early risers.During
the camping trip, the group were not allowed to bring flashlights, flashing
cell phones or any other artificial lights. Only the campfire was lit.A more
current research conducted by a team from University of Colorado, Boulder and
Sweden's Karolinska Institutet and Stockholm Univeristy, saw similar result.
A group of people went on a camping trip for
a week in the middle of winter. Researchers want to know if shorter days and
lower levels of sunlight would be enough to make people to sleep earlier.A
second group was sent on a camping trip for only two days and their body clock
was reset and they had earlier bed times.
According to Kenneth Wright of
University of Colorado Boulder said that living in modern environments affects
the circadian rhythm.Wright said that late circadian and sleep timing may have
negative effects on performance and health.
It could lead into accidents, reduced work
productivity, substance abuse, diabetes, obesity and mood disorders. He added
that people can design their homes and environment to favour daylight and
darkness without having to go on a camping trip.
Cancers can be managed with treatment. Even
better, many can be prevented.
People who believe cancer is caused by
genetic mutations and other factors beyond our control have got it wrong.
Mutations in certain genes do have a strong causative role, such as harmful
mutations in BCRA1 and BCRA2 , with the first raising a women’s risk of breast,
fallopian tube and peritoneal cancers, and BCRA2 raising ovarian cancer risk.
In Men BCRA2 mutations, and two a lesser
extent, BCRA1 mutations, raise risk of breast and prostate cancers.Such clear
causative linkages to cancer are rare. Behaviours and environmental causes well
within your control have a larger role to play and you can take protective
steps against certain cancers, which together are the top five cause of all
deaths in India. Around 30 lakh people have cancer in India, with 11 lakh new
cases and 5 lakh deaths each year.
The most common cause of cancers deaths in
India are lung, breast, liver and cervical and lung cancers.Here is how you can
protect yourself from the most common cancer triggers in India.
***Stop Tobacco use-***
No amount of tobacco use is safe. All forms
of tobacco -- smoking, chewing, snuff and secondhand smoke areca nut (supari)
and betel quid (pan, pan masala), have together made oral cancer the most
common cancer in India. Between them, tobacco in its many chewing, smoking and
sniffing forms account for 30% of all cancers in India.
More men are smoking in India than ever
before, with the number rising by more than a third from 79 million in 1998 to
108 million in 2015, report researchers in BMJ Global Health. Smoking rates
haven’t gone up in women in India, the study found, which partly explains why
lung cancer is the eighth cause of cancer deaths in India, while it is the most
fatal cancer for Indian men and men and women around the world. This is
remarkable given that millions of women in rural India still cook over wood-
and-charcoal fires in porly-ventilated homes, which also increases cancer risk.
***Get Vaccinated Against
Certain Viruses***
Most people don’t link virus infections with
cancer, but viruses such as human papillomavirus (HPV) have been proven to
cause cervical cancer, while hepatitis B and C infections can lead to liver
cancer. There are affordable and effective vaccines that protect against HPV and
Hepatitis B, but there is no vaccine against Hepatitis C.
Cervical cancer is the second most common
cause of cancer death among women in India, but has dropped to the sixth
highest cause globally because several countries have started vaccinating girls
against HPV. Getting vaccinated against both these viruses – Hepatitis B
vaccine is a part of routine immunization in India, and HPV vaacines have been
introduced in some states can protect against cervical cancer in women and
liver cancers in both genders.
***Air Pollution***
We breathe in about 10, 000 litres of air
each day, depending on how active we are. With each breath, we draw in
life-saving oxygen along with carcinogenic contaminants that damage the body
and particularly the lungs over time even when present in trace amounts.
Air contaminants mostly come from the
combustion of fuels for heating, cooking, power generation, industrial
processes and vehicular traffic. Air is unsafe in most parts of India. in rural
areas, it’s burning of dung and wood in open fires wrecks lungs, while urban
hubs battle pollutants from power-generation plants and combustion engines,
particularly for motor vehicles. Indoors carcinogens include tobacco smoking,
building materials, and furnishings, as well as the naturally occurring
carcinogen radon.
Many individual components of air pollution
-- such as particulate matter (dust), soot, (black carbon and titanium
dioxide), diesel engine exhaust, secondhand smoke, solvents, metals (titanium
dioxide) and asphalt (bitumen used for road surfacing) -- are also make it to
the International Agency for Research on Cancer Monographs (IARC), which lists
481 agents and environmental factors that are carcinogenic to humans.
Protect yourself by not lighting open fires,
keep cooking areas ventilated, and wear protective masks in dusty and heavily
polluted roads and industrial areas.
***Alcohol***
Everyone who drinks doesn’t develop cancer,
but studies show that cancers are more common in people who drink than those
who don’t. Drinking alcohol raises the risk of seven types of cancers – liver,
mouth, upper throat (pharyngeal), food pipe (oesophageal), voice box
(laryngeal), breast and bowel cancers.
in the body, alcohol (ethanol) gets converted
into acetaldehyde, which is a toxin that damages DNA by preventing cells from
repairing it and is classified as a possible carcinogen by IARC.
