@CityPowerJhb Block 9 no power since 2pm? @CityPowerJhb please can we have any update?

[Karine Scheuermaier @witssleep]

@CityPowerJhb No power in Block 9 - please can you tell us what is the issue

It's World Sleep Day today!
The South African Society for Sleep and Health (https://t.co/IDDWa9jnLb) wrote about sleep health inequities in the South African context and why sleep is important for our health and well-being.

I feel that this paper with @kirsten_n_red, @KatieChrono, Dale Rae, @XaviGomezOlive and @witssleep might be the most important one I have ever been part of. It describes our observation that people living with HIV seem to live in a state of chronic jetlag. https://t.co/5C4DpsviDB

Excited to announce the publication of our newest paper by @Roche_Johanna @klknut @fxgoic and @witssleep. We've performed home sleep recordings in a deprived part of South Africa and found an alarming prevalence of obstructive sleep apnoea (OSA).

In Southern Africa, truck drivers with HIV have a greater inflammatory susceptibility to circadian misalignment than those without HIV! Shift workers must be given more attention with respect to sleep health and CVD prevention. Thanks @witssleep and team! https://t.co/lij89UMFDI

@javid_lab @Michael_Rick @pickettjessica @TomScriba @emilybethwong Lack of protection demonstrated with humoral (antibody) Immunity but who knows what is happening with cell mediated immunity? T cells warriors of SARS-CoV-2 https://t.co/tHisgnEXhH?

[Karine Scheuermaier @witssleep]

@javid_lab Another thought is that the new variant has been shown to resist antibodies produced with early strain. But what about cellular immunity ?- may be effective. Sweden’s experience showed that not developing severe covid was associated with cellular immunity.

[Karine Scheuermaier @witssleep]

@javid_lab @TomScriba @emilybethwong What may be underestimated is the number of Covid related deaths occurring outside of hospital. I would like to see the excess mortality curve superimposed to those curves. Testing however is widespread and available. Lockdown on Dec 28th may have helped too.

REM sleep in seals may warm the brain? Alternatively, as in humans, it occurs during the circadian temperature rise? https://t.co/dB7mTP2sQ5

[Sleep Research Society @ResearchSleep]

Sleeping fur seals toggle between two #brain patterns: one while at sea, the other on land. Researchers suggest that R.E.M. #sleep serves to warm the brain. https://t.co/xx2Umr61Ma

Proud of our publication on Sleep and HIV in @BrainBehavImm - available online for free until May 3rd https://t.co/gQQF1zS075~

[Karine Scheuermaier @witssleep]

@sibsG It is not a problem in itself but if it bothers you or you are sleepy, why not. You may have other symptoms which need to be explored

[Karine Scheuermaier @witssleep]

New study reported in NY times on how sleep clears the brain of toxins. http://t.co/Sy4jt6Vciz.

[Karine Scheuermaier @witssleep]

@Masechaba_L thanks for inviting me on your show yesterday. Good questions!

[Karine Scheuermaier @witssleep]

@sibsG @Masechaba_L it is caused when we wake up from a stage of sleep called REM, during which our muscles are paralyzed. It may last 1min.
