The Role of Cortisol in Depression

People with depression tend to have reduced measures of serotonin in the brain and elevated levels of cortisol in their bloodstream. Because cortisol is related to stress, implementing a stress-management lifestyle may be an important aspect of coping with your depression. Understanding Cortisol Cortisol is an important hormone produced by the adrenal glands, the small endocrine glands that sit on top of our kidneys. It is secreted by the body in response to stress and is one of the hormones involved in the fight or flight response. Cortisol plays an important role in everything from how the body uses glucose (sugar), to the regulation of blood pressure, to the function of the immune system. In the short run, cortisol secretion has many benefits. It prepares you for physical and emotional [...]

Covid–19: Why sleep could be a lifesaver

Sleep could prove to be a lifesaver when it comes to Covid-19 – both in staving it off and minimising symptoms when it hits. We all know that not getting enough sleep leaves us stressed, tired and likely to overeat, but it also leaves us open to infection. While it’s too early for any studies to have been done on the effects of sleep on this particular coronavirus (Covid-19), in 2015 researchers in the US deliberately infected 164 volunteers with the rhinovirus (common cold). They found that the people who slept less than six hours a night were four times more likely to develop cold symptoms than the ones who slept for seven hours or more. This is because you’re resting when you’re asleep. Through all the phases of sleep your [...]

This virus is very infectious, so it is easy for it to spread from person to person.

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 [...]

Spreading Awareness While You Sleep!

Petaling Jaya, 16 March 2014 – Shoppers were caught by surprise when a ‘sleep mob’ gathered at a major shopping mall to take a public nap in the middle of a busy afternoon. Hosted by leading and best-selling brand of all-natural sleep supplement Rilax Zzz®, the event was held to promote awareness on healthy sleep. The ‘sleep mobbers’ – donned in pyjamas, nighties, bedroom slippers and carrying around pillows, blankets and teddy bears – started appearing from various parts of the crowded mall to assemble at the Ground Floor Promenade of 1Utama Shopping Centre, where everyone got together and promptly took a nap! While dressed in their bedroom best, mobbers took the opportunity to spread some awareness on healthy sleep with fascinating ‘sleep facts’ printed on handheld signs: “Did you know? [...]

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 [...]
