Study Reveals That Starting Work Before 10am Is Ruining Your Health

In case anyone was after confirmation, yes – early mornings suck. They especially suck on weekdays when you have to go into your crappy job on your crappy salary on the crappy train in the crappy rain.

But until society collapses and we no longer need to invest our time in exchange for money in order to survive on this god damn earth, I guess we’ll just need to bite the bullet and go to work.

Considering the average person spends roughly 30 per cent of their life at work, does it not make sense to want to spend it in the least pain possible? Enter science.

Science has your back. Not only has it proven that drinking wine before bed will help you lose weight, it backed it up with proof that eating cheese every day is good for you.

And for its final act: science is pushing for a 10am start on work days, comparing 9am starts to ‘torture.’

The study out of Oxford University found that forcing staff to start work before 10am is making employees ill, exhausted and stressed. Before the age of 55, the circadian rhythms of adults are totally out of sync with the average 9-5 working hours, posing a serious threat to employees’ performance, mood and mental health.

Study author Dr Paul Kelley says sleep deprivation is particularly damaging on the body’s physical, emotional and performance systems.

“Your live and your heart have different patterns and you’re asking them to shift two or three hours. This is an international issue. Everybody is suffering and they don’t have to,” Kelly said.

And despite contrary belief, no – you cannot change your circadian rhythms.

“We cannot change our 24-hour rhythms,” said Kelly. “You cannot learn to get up at a certain time. Your body will be attuned to sunlight and you’re not conscious of it because it reports to hypothalamus, not sight.”

Just one week with less than six hours sleep each night leads to 711 changes in how genes in your body function. Lack of sleep impacts performance, attention and long term-memory, and can also lead to exhaustion, anxiety, frustration, anger, impulsiveness, weight-gain, risk-taking and high blood pressure.

So when you’re forced to wake up or go to work earlier than what your body wants to, your sleep deprivation is putting your body under a huge amount of stress, and “sleep deprivation is a torture.”

Your move? Maybe don’t (actually, just don’t) accuse your boss of torturing you, but instead raise the topic of coming into work a bit later and back it up with the potential benefits like higher quality work, a greater work ethic and an improved mood.

Sleep Paralysis : What really happens?

What REALLY happens when you see a ghost: Bizarre brain activity behind ‘sleep paralysis’ is finally revealed

• Sleep paralysis occurs in rapid eye movement sleep, or dream sleep
• It causes the sufferer to feel as though they are awake but can’t move
• They may also see vivid hallucinations, such as ghosts or demons
• This is caused by mix-up in part of the brain dubbed the parietal lobes
• The lobes holds a map of the ‘self’ which is distorted due to paralysis

Lying in her bed in the middle of the night, Elizabeth Earle woke suddenly to see a menacing shadow in her room. She tried to scream, but couldn’t open her mouth.
What Ms Earle felt was ‘sleep paralysis’ – a terrifying phenomenon that 40 per cent of people experience at some point in their lives.
Now US researchers believe they know why this strange experience occurs, and it’s all to do with a mix-up in an area of the brain that holds a neural map of the ‘self’.

They believe sleep paralysis takes place when a person wakes up during a stage of sleep known as rapid eye movement (REM), in which they are usually dreaming.
REM lasts for around five to 15 minutes and is repeated roughly every 90 minutes throughout the night.
Although the person is awake, their muscles are nearly paralysed, which may be an evolutionary device to keep people from sleep walking while dreaming.

But among those who experience sleep paralysis, a small group of people also feel as though there is a demonic figure in the room, pressing down on their chest.

Scientists at University of California, San Diego, say that one explanation is that there’s a disturbance in the brain region that holds a neural map of the ‘self.’
‘Perhaps, in part of the brain, there’s a genetically hardwired image of the body – a template,’ Baland Jalal, a neuroscientist at the University of California, San Diego told Live Science.
The researchers suggest that this hardwired image could be located in the parietal lobes – the top-middle part of the brain.
When a person suddenly wakes up during REM sleep, the parietal lobes monitor neurons in the brain that command muscles to move.
However, the limbs are temporarily paralysed, causing a disturbance which manifests itself as a hallucination.
The appearance of a ghost or demon could result when the brain tries to project the person’s own body image onto a hallucinated figure, said Dr Jalal.
If this idea is true, people who are missing a limb might hallucinate figures who are missing the same limb, he added said.
The paper, entitled Sleep paralysis and ‘the bedroom intruder’: The role of the right superior parietal, phantom pain and body image projection is published in the journal Medical Hypotheses.
