Sleep linked with hunger
A new study has found that a person's appetite can be enhanced
if they haven't had enough sleep, which establishes a possible link
between poor sleep and obesity.
Researchers at the Department of Neuroscience at Uppsala University
in Sweden discovered the link by giving 12 men MRI scans to observe
the brain when the men look at pictures of food.
The researchers found that there was more activity in the appetite
centre of the brain when they were sleep deprived than when they
had a normal night's sleep.
Rest is often underappreciated in a modern society where routine
and habit can be difficult to put into action. That being said,
spending enough time tucked up in bed
should be something you do regardless of your working/playing
schedule. There are several myths about sleep that lead people to
break habits and abuse the importance of sleep in a daily
According to the National Institute of Health, many people believe
just one hour less sleep per night doesn't affect how they function
throughout the day. Unfortunately, this is way off the mark. Even
slightly less sleep can compromise cardiovascular health, which
will affect the ability to respond adequately and maintain energy
levels. It can also affect hunger patterns, as shown by recent
results from Sweden.
It is also commonly believed that your body adjusts quickly to
different sleep schedules. The false nature of this statement can
be compared to long-distance jetlag. Many people take weeks to
recover from the time difference, and adjusting sleep patterns by
just one to two hours can have similar affects at home.
Oversleeping can be as detrimental to health patterns as under
sleeping, as it is more important to have quality sleep rather than
a large quantity of sleep. Disjointed sleep that spans for over
eight hours is worse than consistent sleep that lasts for less than
Dr William Kohler, director of the Florida Sleep Institute in
Spring Hill, Florida, commented in Daily RX: "Sleep is very
important in homeostasis and energy balance, and lack of sleep
adjusts the hormonal excretions in our body."
