Getting good sleep during the covid-19 pandemic

Coronavirus stress and sleep Coronavirus COVID-19 is a new infection that has spread around the world in recent months. This is a pandemic. This virus is very infectious, so it is easy for it to spread from person to person. To prevent COVID-19 from spreading too quickly and too widely, governments all around the world have placed restrictions on what people can and cannot do. There has also been a lot of media reports about COVID-19 and the associated economic impacts and health effects of this virus. All of these things can easily make people anxious and stressed. This is natural when there are many unknown factors. Fear and anxiety can cause strong emotions in adults and children, which may result in difficulty sleeping. When our sleep is of a [...]

How sleep can fight infection

Researchers in Germany have discovered why sleep can sometimes be the best medicine. Sleep improves the potential ability of some of the body's immune cells to attach to their targets, according to a new study that will be published February 12 in the Journal of Experimental Medicine. The study, led by Stoyan Dimitrov and Luciana Besedovsky at the University of Tübingen, helps explain how sleep can fight off an infection, whereas other conditions, such as chronic stress, can make the body more susceptible to illness.   T cells are a type of white blood cell that are critical to the body's immune response. When T cells recognize a specific target, such as a cell infected with a virus, they activate sticky proteins known as integrins that allow them to attach [...]

Stockpile on sleep, not supermarket staples to protect from Covid-19

As panic-buyers continue to leave supermarket shelves bare, University of South Australia sleep experts are reminding people that it's sleep that they need to stockpile if they want to ensure the best possible health during the pandemic. UniSA sleep and fatigue researcher, Dr. Raymond Matthews says prioritizing sleep will help protect you from COVID-19 by boosting your immune system. "As the reality of Covid-19 steps up, people are rightly more vigilant with handwashing, social distancing and working from home if they can. But what they may not realize is how important sleep is to their overall health," Dr. Matthews says. "Sleep plays a vital role in the function of the body's immune system. When people suffer from a lack of sleep, they're reducing their body's natural killer cells—the white blood [...]

Cortisol and its effects on your sleep

It’s a hot topic in sleep research: the relationship between cortisol and the quality and patterns of sleep. I’ve been talking about cortisol for a while, but I’ve never devoted a stand-alone article to this important topic. It’s time to correct that. Today, I’ll talk about the role that cortisol plays in the sleep-wake cycle, how disruptions to healthy cortisol levels interfere with sleep and contribute to sleep disorders—and how poor sleep, in turn, negatively affects cortisol. I’ll also discuss ways to encourage healthy cortisol levels, for the benefit of your sleep and broader health. What does cortisol do? Cortisol is a stimulating, alerting hormone. It’s the body’s primary stress hormone—that’s the role that gets cortisol most of its attention. Urged on by a complex network that incorporates elements of [...]

Lack of sleep affects our ability to fight Covid-19

Singapore, 20 March 2020 – As nations across the world battle against the spread of Covid-19, one behavior that jeopardizes immunity is the lack of sleep. Singaporeans, in particular, should take note. A survey performed in late 2018 confirmed that Singaporeans are not getting enough sleep. The survey1 performed by international market research agency YouGov found that 44 per cent of Singaporeans are getting less than seven hours of sleep a night. Its head, Mr Jake Gammon noted that “demanding work” could be the cause of sleepless nights. He said, “In a fast-paced metropolis like Singapore, only about half its citizens are getting enough rest. What’s particularly worrying is lower-income Singaporeans are twice as likely to get less than four hours of sleep a night.” There is a science behind [...]

Making Sleep Your No. 1 Priority Can Help Prevent & Overcome Illness

Strengthen and Boost Your Immune System with Sleep As world-wide anxiety builds around the spread of coronavirus, one behavior that has been proven time and time again to reduce the incidence and intensity of disease is getting sufficient sleep. In honor of World Sleep Day, and because sleep may be particularly important during a potential pandemic, we’ll dive into the science behind the relationship between sleep and immunity. How Sleep Affects Your Immune System While the COVID-19 disease and the novel coronavirus that causes it are new and therefore relatively poorly understood and understudied, research by Dr. Aric Prather out of UC San Francisco on another type of Coronavirus - the common cold - demonstrated that “people who sleep six hours a night or less are four times more likely [...]

Adequate Sleep Can Help Fight Covid-19

KUALA LUMPUR: Adequate sleep is the best way to enhance and improve the immune system, and subsequently help to reduce the risk from contracting Covid-19. Dr Nurul Yaqeen Mohd Esa, who is a respiratory specialist and general physician at Sunway Medical Centre Velocity (SMCV), said research has proven that an adult needed at least seven hours of sleep to sustain health. On the other hand, lack of sleep will make our immune system weak, she said. “Studies have also shown that between 30 and 40 per cent adults do not get enough sleep, nor do they have knowledge on how much sleep they should be getting. “Many doctors and healthcare providers in China have died because of the infection, partly from overwork and lack of sleep,” she added. Although the [...]

How You Can Use Sleep to Fight Back Against Coronavirus

The coronavirus outbreak that has devastated China and left the world scrambling for answers has also reinforced the important role sleep plays in building our immune systems. In a nutshell: Making sure we consistently get a good night’s sleep is one of the best ways we can improve our immunity and defend against viruses and disease. Sleep is a natural immune booster. To be clear, I’m not suggesting sleep is a cure-all for the coronavirus. That isn’t the case; currently, there is no vaccine for the infection. The coronavirus has, by Feb. 20, killed more than 2,100 people globally. Altogether, nearly 75,000 cases have been confirmed, mostly in China, where the country has ground to a halt as it looks to safeguard against a further outbreak. The coronavirus has also become a [...]
