Lack of sleep may cause your brain to eat itself or cause dementia

When you go without sleep for 20 to 25 hours, your performance impairment is similar to that of someone with a blood-alcohol level of 0.10 percent. At 36, 48, and 72 hours without sleep, your body and your mind begin operating in altered states that put your health, and your life, at risk.

All-night study sessions, important business deals, new babies — most people will experience a taste of sleep deprivation at some point in life. While the occasional lack of sleep may not seem like a big deal, the impact of sleep deprivation can be intense and its effects can linger. In extreme circumstances, sleep deprivation can ultimately lead to death.

Lack of sleep can cause parts of the brain’s synapses to be ‘eaten’ by other brain cells, according to a new study by researchers at the Marche Polytechnic University in Italy.  Astrocytes are a cell in the brain that clean out worn-out cells and debris. Scientists studying the brains of mice found these cells were more active when the animals had been deprived of sleep, breaking down more of the brain’s connections.

It was also discovered that microglial cells become more active after sleep deprivation. Previous research has found that chronic sleep deprivation increases so-called plaques in the brain thought to be a main cause of Alzheimer’s and other dementias.

It’s not just how long you sleep that matters. The quality of your sleep is just as important. Every night you need to go through several stages of sleep – falling peacefully into a deep sleep and periodically returning to so-called REM (Rapid Eye Movement) sleep before entering another period of deep sleep or waking up. During REM sleep,( which is when we dream) your brain is quite active, which is believed to be due to the brain consolidating recently learned information and transferring it into long-term memory. That’s one of the reasons why, we need both deep and REM sleep, because the right type of sleep, as well as the right amount of sleep, is so important for school children.



The consequences of sleep deprivation at 24 hours is comparable to the cognitive impairment of someone with a blood-alcohol content of 0.10 percent, according to a 2010 study in the International Journal of Occupational Medicine and Environmental Health. “Judgment is affected, memory is impaired, there is deterioration in decision making, and a decline in eye-hand coordination,” Cralle says. “You’re more emotional, attention is decreased, hearing is impaired, and there is an increase in your risk of death from a fatal accident.”

At 36 hours your health begins to be at risk. High levels of inflammatory markers are in the bloodstream, said Cralle, which can eventually lead to cardiovascular disease and high blood pressure. Additionally, hormones are affected — your emotions can be all over the place.

Not all instances of sleep deprivation are voluntary. Insomnia, sleep apnea, restless legs syndrome, night terrors, sleepwalking, and other problems can affect sleep. See your Doctor if you experience any sleep problems.

Crimewatch axed by BBC after 33 years

The programme, which asks viewers for help to track down criminals, is hosted by Jeremy Vine and Tina Daheley.

The BBC said in a statement:

“We are incredibly proud of Crimewatch and the great work it has done over the years. This move will also allow us to create room for new innovative programmes in peak time on BBC One.” Daytime series Crimewatch Roadshow will continue. We believe the successful Crimewatch Roadshow format in daytime is the best fit for the brand going forward and we will increase the number of episodes to make two series a year.”

The Sun, which first broke the story, said ratings had suffered as it was scheduled against Cold Feet and Broadchurch.  Three episodes have aired this year – in February and March – watched by an average of almost three million viewers. That is down from 14 million who watched at its peak.

Speaking on BBC Radio 4’s Today programme, former Crimewatch presenter Nick Ross said:

“I’m amazed that it’s gone on for so long. And it’s a tribute to the team they’ve kept it going.

“When it started, it was revolutionary. Up to that point, television and radio basically talked at the audience. There was no internet, very few phone-ins, this was a programme where the audience could talk back and could actually influence the end of the programme.

“This sort of revolutionary thing then had a huge impact on television generally and has kept going for 33 years despite all the changes in technology.”

Ross said falling ratings had had an impact on crime-solving.

“If you get 15 million people watching a programme and you have an appeal, the chance of finding somebody, that one witness who saw something they had no idea was connected with the crime… they can ring in.

“Once your audience starts plummeting, you go back to two million, one million, your chances of finding that person are so remote.’

The Police Federation said it was a “shame” that the programme was ending, and that it had shown “the complex side of policing and solve crime”.

Simon Kempton, the Police Federation’s head of operational policing, said:

“For those wider appeals which needed national coverage it was great and there has been nothing else that has been able to give cases such a wide reach, but if there aren’t the audience figures and people aren’t watching it then you have to move with the times.”

How to protect yourself from cyber bullying and online harassment #BeCyberSmart

Most people set up an account on a social media site like Facebook or Twitter so that they can share what is happening in their lives and interact with friends and family online.

West Mercia Police are working with a number of charities, schools, care professionals, spokespeople and other partners to share information Advice on cyberbullying and online harassment

It is important to take care when choosing security settings when you set up your social media account. These will specify exactly who can see your updates. This is important as you need to be aware of who can see what you are sharing. You are in charge of this and can change who can see your updates at any point. While such sites allow you to stay in touch with loved ones, there is always a risk that you will come across people who will abuse the privilege of having access to your updates. Sadly, the internet makes it easy for people to annoy, insult, pester or spy on others, resulting in an increase of these kinds of behaviours.

The perpetrators are sometimes the same people who would harass someone offline (in ‘real life’), but there are also people who ‘hide’ behind their computer, thinking that it makes them invisible to the people they are harassing. If your a teacher, or even a young adult who enjoys social media you should read A young persons guide to cyberbullying and online harassment  Victims can be of any age, male or female, from any social or ethnic background and live anywhere.

Cyberbullying and online harassment can be extremely distressing. It can  be classed as a criminal offence but there is lots of help available to support you. Tips to stay safe online

If you believe that you are the victim of someone’s online activity that is abusive or malicious, there are a number of places you can go to for help.

  • Gather and document as much evidence as you can.
  • Find out more about how cyber stalkers work by visiting Get Safe Online.
  • Seek help and support from relevant organisations, for example the National Stalking Helpline on 0808 802 0300, or email advice@stalkinghelpline.org
  • As with cyber bullying you can report bad behaviour on most social networks including Twitter and Facebook.
  • If you think the trolling is libellous or threatening, you can report it to the police.
