How Does The Body React To Lack Of Sleep?

Adults (aged 26-64 years) need at least 7-9 hrs of sleep daily. Sleep deprivation of 18-24 hrs slows down mental and physical responses, and impairs cognition. Not sleeping for more than 48 hrs sleep reduces the number of NK cells of the immune system and spikes BP. Pushing the limit even further induces hallucinations, pain, tremors, glucose intolerance, and disruption of senses. Lack of sleep is associated with dipping alertness, weakening cognitive performance, decreased brain function and activity, and poor attention. This can lower productivity at the workplace, endanger your well-being, and even become a safety hazard.

How Much Should You Sleep?

Going by the National Sleep Foundation’s recommendations for an adult between 26 and 64 years, 7 to 9 hours of sleep every day is a good goal. That said, you could get away with 6 hours of sleep, but no less. The average person needs to get some sleep every 17-18 hours. Any longer without sleep and your body starts to show signs of sleep deprivation.1


The Progressive Decline

To understand the ramifications of staying up that little bit longer, take a look at what happens to your body with each progressive hour of sleep lost.


18–24 hours

This kind of sleep deprivation is fairly common in some professions and even among single parents or working parents who are also primary caregivers for their family.

Sleep deprivation causes a decline in vigilant attention. Your responses slow down, you tend to make errors, and you take longer to do tasks.2

According to one study, subjects who had gone 17 to 19 hours without any sleep showed performance on tests not unlike those with blood alcohol levels of 0.05 percent. These sleep-deprived individuals responded as much as 50 percent slower on some tests. Their accuracy of responses also took a hit and was significantly worse than what is associated with people with blood alcohol content (BAC) of 0.05 percent. As the hours without sleep increased, the performance was closer to those with BAC of 0.1 percent.3 The researchers concluded that sleep is a biological necessity to ensure normal brain function, keep you alert, and maintain normal cognitive performance.4

48 hours

This kind of extended sleep deprivation is not usual for the average person. Those in emergency services or military forces, for instance, may have to go a few days without sleep.

Longer periods of sleep deprivation are believed to impact the immune profile of the body, making you more susceptible to diseases. One study investigated this premise in subjects who went 48 hours without sleep. The body’s natural killer cells (a type of lymphocyte or white blood cell) that are a core part of the human immune system were found to be much lower. This decrease with 48 hours of sleep deprivation could be reversed when subjects went through recovery sleep. However, if this level of sleep loss is sustained for longer spells, it could have a bearing on the body’s ability to fight tumors and viruses

With this kind of sleep deprivation, blood pressure and heart rate also rise, putting you at greater risk of a stroke. As one study showed, sleep deprivation causes the body’s diastolic blood pressure to increase and interfere with the autonomic nervous system’s regulation of the cardiovascular system.6

Your body tries to compensate by indulging in microsleeps where it effectively “shuts down” for spells of up to a thirty seconds. After each microsleep you return to reality a bit disoriented. This is potentially dangerous if you are driving, handling heavy machinery or hazardous materials, or are in a job that puts people’s lives in your hands. It is impossible to avoid these microsleeps that occur on their own and cannot be consciously overridden by willpower or otherwise.7

72 hours

As time progresses, you will see issues with higher mental processes. Motivation becomes a challenge for many. Perception also gets hampered. Hallucinations are also experienced by some people after staying up three days. Others may create false memories in their minds. Your senses (smell, sight, and even touch) get impacted adversely. Tremors and physical aches and pains also start to set in. And all this in addition to the signs you would have seen after earlier stages of sleep deprivation!8

How Far Can You Push It?

Chronic deprivation messes with the glucose metabolism of the body. Getting under 6.5 hours of sleep every night on a sustained basis could cause your glucose tolerance to drop by 40 percent. Poor glucose tolerance puts you at higher risk of developing type 2 diabetes.Those with total sleep deprivation fare even worse as the glucose secretion pattern changes completely compared to those experiencing normal nocturnal sleep.9

Deprivation also decreases energy expenditure and interferes with your appetite. Researchers found that people experiencing a regular lack of sleep have a higher body mass index (BMI) than those who get their complete recommended rest. Inadequate sleep causes changes to levels of hormones responsible for controlling hunger. Appetite-reducing leptin levels dropped, and appetite-stimulant ghrelin levels were higher in those who got less sleep. Losing that sleep may actually cause you to crave calorie-rich foods, sweets, carbs, and starchy food, putting you at risk of obesity.10

Sleep deprivation on an ongoing basis can result in long-term ailments and metabolic disorders, costing you time, money, and your health. It may be well worth reorganizing your life so you don’t miss out on this vital restorative time for your body.

    The plane, an American Airlines flight bound for London, turned back to the gate in Los Angeles when the hotspot, entitled “Al-Quida Free Terror Nettwork” (sic), was spotted in a list of available connections. The passenger notified a flight attendant while the plane was taxiing.

    Flight 136 had been due to take off this past Sunday at 8pm but was held in LAX for three hours while passengers were told to turn off their electronic devices, ABC 7, an American news network, reports.

    9:00pm  |   CORONAVIRUS: Three billion under lockdown

    Let me leave you with this five-minute read that should paint for you a picture on what's happening around the world as the United Nations warns that humanity is under threat.

    This story is by AFP:

     

    More than three billion people are living under lockdown measures to stem the spread of the killer coronavirus that the United Nations warned Wednesday is threatening all of humanity.

    As the global death toll soared past 20,000 Spain joined Italy in seeing its number of fatalities overtake China, where the virus first emerged just three months ago.

    "COVID-19 is threatening the whole of humanity -– and the whole of humanity must fight back," UN Secretary General Antonio Guterres said, launching an appeal for $2 billion to help the world's poor.

    "Global action and solidarity are crucial. Individual country responses are not going to be enough."

    Markets rebounded after Washington vowed to spend $2 trillion to fend off a US economic collapse, while governments elsewhere are still taking ever more dramatic steps to contain the disease.

    India's stay-at-home order for its 1.3 billion people is now the biggest, taking the total number of people facing restrictions on their daily lives to more than three billion.

    Russia, which announced the death of two patients who tested positive for coronavirus on Wednesday, is expected to follow suit.

    President Vladimir Putin declared next week a public holiday and postponed a public vote on controversial constitutional reforms, urging people to help each other and follow instructions given by medics and the authorities.

    In Britain, heir to the throne Prince Charles became the latest high-profile figure to become infected while Prime Minister Boris Johnson praised the country's response to tackle the outbreak despite accusations it was slow to act.

    The G20 major economies will hold an emergency videoconference summit on Thursday to discuss a global response to the crisis, as will the 27 leaders of the European Union, the outbreak's new epicentre.

    China has begun to relax its own draconian restrictions on free movement in the province of Hubei -- the original epicentre of the outbreak -- after the country reported no new cases.

    Huge crowds jammed trains and buses as people in the province of 50 million people took their first opportunity to travel.

    But Spain saw the number of deaths surge to 3,434 after more than 738 people died in the past 24 hours and the government announced a 432-million-euro ($467 million) deal to buy medical supplies from Beijing.

    'People dying alone'

    At La Paz university hospital in Madrid, accident and emergency nurse Guillen del Barrio sounded bereft as he related what happened overnight.

    "It is really hard, we had feverish people for many hours in the waiting room," the 30-year-old told AFP.

    "Many of my colleagues were crying because there were people who are dying alone, without seeing their family for the last time."

    Spain and Italy were joined by France and six more EU countries in urging Germany and the Netherlands to allow the issue of joint European bonds to cut borrowing costs and stabilise the eurozone economy.

    This is likely to fall on deaf ears when the 27 leaders talk on Thursday -- with northern members wary of pooling debt with big spenders -- but they will sign off on an "unprecedented" recovery plan.

    Coronavirus cases are also spreading in the Middle East, where Iran's death toll topped 2,000, and in Africa, where Mali declaring its first case and several nations announced states of emergency.

    And in Japan, which has postponed this year's Olympic Games, Tokyo's governor urged residents to stay home this weekend, warning of a possible "explosion" of the coronavirus.

    The impact of the pandemic is also hitting European football in a big way, with top-flight leagues and tournaments cancelled.

     

    'Wartime level of investment'

    The economic damage of the virus -- and the lockdowns -- could also be devastating, with fears of a worldwide recession worse than the financial meltdown more than a decade ago.

    But financial markets rose after US leaders agreed a stimulus package worth roughly 10 percent of their economy, an injection Senate Majority Leader Mitch McConnell said represented a "wartime level of investment".

    The US Senate was poised to pass the massive relief package for Americans and businesses ravaged by the pandemic as New York hospitals braced for a wave of virus patients,

    Meanwhile, nearly 130 million Americans, or 40 percent of the population, are under or will soon come under some lockdown order, including in the largest state of California.

    President Donald Trump has voiced hope the US will be "raring to go" by mid-April, but his optimism appeared to stand almost alone among world leaders.

     

    Anxious Indians raced for supplies after the government ordered the world's second-biggest population to stay at home for three weeks from Wednesday.

    "To save India, to save its every citizen, you, your family... every street, every neighbourhood is being put under lockdown," Prime Minister Narendra Modi said.

    Whether the order will be obeyed in full remained to be seen. Mumbai vegetable trader Rafiq Ansari said his customers were getting angry over shortages and price hikes.

    "I don't understand what's going on," the 35-year-old told AFP. "We are going to face major shortages in the days ahead."

    Iran announced it would ban intercity travel as it finally got tough with the virus that has killed more than 2,000 people in one of the world's deadliest outbreaks.

    Many governments are listening to health experts who warn the only way to slow the epidemic -- and save the lives of the elderly and vulnerable -- is by imposing "social isolation" measures.

    President Yoweri Museveni's message is clear, and key among the additional measures are the following:

    - Public transport has been suspended for the next two weeks.

    - Markets have been limited to selling only foodstuffs.

    - Only essential staff to be allowed in government offices.

    8:39pm  |   'What we are dealing with has been handled before'


    While concluding his speech, the President makes a biblical allusion (Isaiah 26:20) to contexualize what the world is going through at the moment in the face of the coronavirus pandemic.

    The scriptural extraction says (depending on the version of the Bible you are using): "Go, my people, enter your rooms and shut the doors behind you; hide yourselves for a little while until his wrath has passed by."

    "What we are dealing with have been there before and have been handled," says Museveni.

    He wraps up his speech by reminded the public that eight of the original nine coronavirus cases in Uganda are recovering steadily. The other one is not steady yet.

    "I wish you good luck, I wish you God's protection. Thank you very much," he signs off.

    8:35pm  |   Government vehicles to be stationed at district headquarters

    Museveni says: "Now that we have got cases in other parts of the country (beyond Kampala and Entebbe), we have a system of getting samples from suspected people all the way to Entebbe for testing. There are teams near villages who do surveillance.

    "These inform people who are at the 100 hubs across the country, who in turn take samples [from the suspected people] and send them to Entebbe aboard Posta Buses."

    To ease this countrywide surveillance, the President says: "I am directing that all govenrment vehicles in the districts (except the ones for the army and Police) should be centralised at the district headquarters under the command of the district health officer, aided by a Police officer.

    "We are going to ensure that [these vehicles] have enough fuel."

    "Each ministry and government department should work out a plan of the essential staff that need to remain on duty," says the President.

    This can be done on rotational basis.

    "At district level, district officials can identify boda bodas who can deliver food and other cargo to wherever it is needed. This  crisis will teach us other methods of doing business," adds the President.

    8:23pm  |   Markets to sell only food - nothing else

    After dealing with public transport, the President says the other big problem are the markets, as they bring together many people.

    He, however, says he is happy to learn that the people in these markets have tried to adhere to hygiene measures - washing of hands with soap and water. But that is not enough.

    Therefore, the  second new additional measure is that the markets should be for selling only food - matooke, sweet potatoes, caassava, rice, beans, peas, chicken, meat, etc.

    Save for food, the selling of other items has been suspended.

    "We think this will reduce numbers and then they can maintain social distance. We think by removing the non-food items and sellers, it will reduce the numbers," says Museveni.

    8:18pm  |   Ambulances allowed to move

    The only other vehicles allowed to move are ambulances, vehicles of security agencies and some institutions as well as vehicles for sanitary services (like KCCA garbage collection trucks).

    "This is to cause people to postpone their unsafe journeys from one point to another point. The only people who can move safely are those moving using private cars," says the President.

    8:13pm  |   Government suspends public transport

    In its latest measures, the government has decided to suspend all public transport - that includes taxis, coasters/minibuses, buses, passenger trains, auto rickshaw (tuk tuks) and all boda bodas.

    The suspension is for 14 days.

    Why this suspension?

    "Because we want to limit movement. The only vehicles to move should be private vehicles, which should carry no more than three people, including the driver," says the President.

    But there are a few exceptions.

    Trucks and lorries delivering cargo (food and other essentials) are allowed to continue moving.

    The President says that boda bodas and tuk tuks can move only if they are carrying cargo. He says boda boda riders should not simply sit back and sulk over the suspension of their services - instead, they should think about using their bikes to transport cargo.

    The president is speaking to the nation.

    He says the original nine cases are in "good condition" and their temperatures are going down - save for one, whose temperature keeps flactuating.

    "We are going to get scattered cases across the country. Therefore, we are happy that we took the other big steps in the past - we closed the schools in time and we closed the churches and mosques."

    With more coronavirus cases coming up, the President says the country needs to take additional measures.

    7:43pm  |   'Nothing has caused prices of food to be hiked'

    In his fourth address on Tuesday, President Museveni reiterated his call to Ugandans to adhere to his and the health ministry's directives aimed at arresting the spread of the new coronavirus within the population.

    In his message, he mentioned that he may call a ban on the usage of public transport in case the situation worsens. In doing so, he would also promote using bicycles as an ideal alternative.

    The President also warned "crooks" against hiking the prices of especially foodstuffs, saying he would use spies to catch anyone taking advantage of the situation. If found, a culprit will be arrested and their license revoked.

    "Nothing has caused prices of foodstuffs to be hiked. The bananas we had yesterday are the same today, the maize is the same. So the crooks who are taking advantage of coronavirus to hike prices of foodstuffs anywhere in this country will be arrested and their licenses revoked," he reechoed his warning in a tweet.

  • Necklaces changing lives of HIV-positive widows

    That the necklaces are beautiful is simply unquestionable. From the bright colours of the beads which are stringed together to make a lace (dazzling yellows and reds and greens) to the different shapes in which the beads come (oval, triangle, mango, name it), there is a lot to buoy the eye or the mind that can recognise beauty.

    Yet still, nothing observable about those beautiful, bright-coloured necklaces serves to prepare a beholder for the incredible story behind those handicrafts. A story of necklaces some have called magical for the way they have been able to turn around the lives of everyone connected to them.

    We are talking about the necklaces made by the women of Meeting Point International (MPI), an NGO in Nakawa division, which works to improve the lives of poor women living with HIV –particularly around Kireka and Naguru areas in Kampala.

    MPI was founded 22 years ago by Rose Busingye, a woman who, upon returning to Uganda from a 10-year sojourn in Italy, just couldn’t watch passively as positive women living with HIV in her neighbourhood of Kireka were dehumanised and destroyed by the disease.

    Busingye says: “I saw that the women were very poor and had problems finding food, shelter and other provisions, not only for themselves but their families too. Being HIV positive in tough conditions had made their life hell, and they needed help to begin living meaningful and fairly dignified lives.”

    Busingye got some of her own money and added to it what she was able to raise from her friends overseas, then began seeking out the suffering women and trying to help them live better lives. She registered the NGO Meeting Point in order to have her initiative working in an organized manner.

    “She would help us with medication as well as food to eat,” says 68-year old Janet Nabirye, who was one of the first to join Meeting Point Kireka in 2000. “She also would find sponsors to pay our children’s school fees.”

    Starting to make Necklaces
    Busingye recalls that as the number of women she was helping increased, it became very challenging to meet the bills, and she had to figure out a way the women could also help themselves.

    Since most of them had formerly been working in the stone quarry, breaking stones, she only had to find something that would both bring in some more money and also not wear them out since most were living with HIV. “I had seen a few of them making crafts, and since I knew that crafts had a market in Europe, I settled on introducing craft making as a business for Meeting Point,” Busingye says.

    The women shared their craft-making skills among themselves, and a few volunteers from Europe also came and offered them some training. Tina Kabakunirwa, who has been with Meeting Point since 2004, recalls that the necklaces were just part of several other handcrafts that the women made, others including sweaters, mats among others. She says the ladies in fact still make other crafts alongside the necklaces, only that the necklaces sell most and have eventually become the flagbearer of all crafts they make.

    The process of making the necklaces

    The necklaces are made primarily from waste paper – all sorts including newspapers and magazines, among others. The process starts with making of beads, and here magazine pages are marked off and cut into long, thin triangles.
    The triangles are then rolled around a needle and sealed with glue, creating an egg-shaped bead. The beads are then threaded onto a string and vanished to give them a glossy shine –the varnish taking two to three days to dry.

    The women make their necklaces as individuals, mostly at home, each making her own unique and creative designs.
    Then each presents their product to Meeting Point, which puts all the products together and looks for market for everything –most going overseas. However, each woman receives payment for her particular products as they sold.

    How the necklaces have changed the women’s lives

    Josephine Atimango, a member, says, “Necklace and bead-making has been a wonder for us. Many of us never used to have food at home, we used to toil for long hours in the quarries of Kireka to get something to survive on, but now we no longer need to do that.” SRC: Monitor
