Don 39;t Wake Me Up _HOT_
Yves Pottenburgh
Many factors play a role in preparing your body to fall asleep and wake up. Your body has several internal clocks, called circadian clocks. These typically follow a 24-hour repeating rhythm, called the circadian rhythm. This rhythm affects every cell, tissue, and organ in your body and how they work. Learn more in our Circadian Rhythms Disorders page.
Your body has a biological need for sleep that increases when you have been awake for a long time. This is controlled by homeostasis, the process by which your body keeps your systems, such as your internal body temperature, steady.
A compound called adenosine is linked to this need for sleep. While you are awake, the level of adenosine in your brain continues to rise. The rising levels signal a shift toward sleep. Caffeine and certain drugs can interrupt this process by blocking adenosine.
Your Executive Council has worked diligently to rebuild our society, enabling it to continue to support our local medical community and our patients. We contracted with the North Carolina Medical Society to provide administrative support even as we remain an entity distinct from the NCMS. We revised our mission to focus on maintaining and building collegiality amongst our members and to combat isolation. WCMS cannot solve all of the challenges facing medicine but can help maintain personal and professional connections that are vitally important. We have every reason to be proud of our ancient profession. We have just elected a strong new team of leaders and extensively revised our bylaws to support continuity and enable us to meet the challenges ahead more efficiently. Our website www.wakedocs.org has been upgraded. In 2024 we shall offer more varied programs to bring our members and their families together and attract new members. Much remains to be done. You have a part to play in our future. All of our medical community are welcome, whether you are employed, an independent practitioner, retired, or a medical trainee to be a part of Wake County Medical Society.
A separate study I conducted of newspaper coverage in the wake of the 2016 election found that about a third of news stories and op-eds argued that Clinton lost because of her focus on identity politics.
Supply chains across industries are going through an unprecedented global disruption in the wake of the Covid-19 pandemic which has shuttered airports, seaports and hampered the movement of goods and people around the world.
A funeral celebration, common in Ireland, at which the participants stay awake all night keeping watch over the body of the dead person before burial. A wake traditionally involves a good deal of feasting and drinking.
Little is known about sleep/wake abnormalities in intensive care and less is known about the mechanisms responsible for these abnormalities. We studied 22 (20 mechanically ventilated) medical intensive care unit (ICU) patients with continuous polysomnography (PSG) and environmental noise measurements for 24-48 h to characterize sleep-wake patterns and objectively determine the effect of environmental noise on sleep disruption. All 22 patients demonstrated sleep-wake cycle abnormalities. There were large variations in total sleep time (TST) with the mean total sleep time per 24-h study period of 8.8 +/- 5.0 h. Sleep-wake cycles were fragmented and nonconsolidated with a mean of 57 +/- 18% and 43 +/- 18% of the TST occurring during the day and night, respectively. Environmental noise was responsible for 11.5 and 17% of the overall arousals and awakenings from sleep, respectively. The mean noise arousal index was 1.9 +/- 2.1 arousals/h sleep.
Conclusions: (1) ICU patients are qualitatively, but not necessarily quantitatively, sleep deprived; and (2) although environmental noise is in part responsible for sleep-wake abnormalities, it is not responsible for the majority of the sleep fragmentation and may therefore not be as disruptive to sleep as the previous literature suggests.
