@NH_RC research on the @USNSComfort… exploring wearables for early detection of illness and sleep issues #navymedicine

[Rachel Markwald, PhD @R_Markwald]

Definitely! And add @evanchinoy for the complete @NH_RC sleep team from the lab validation side to the operational research team

[Rachel Markwald, PhD @R_Markwald]

@lizfyne @CSoSleepy @UAsleephealth @michaelgrandner I can definitely see why you might think that! We have looked at clothing sensors too

[Rachel Markwald, PhD @R_Markwald]

@BrandonPetersMD Wow, the amount of inaccuracies is just alarming.

Naval Health Research Center STEEL team partnered with CNSF on the CREW program in the quest for an operational risk management system that will flag people, crews or task groups operating with too many red flags (e.g., high fatigue) https://t.co/isiYIiWKJF @NH_RC @NavyMedicine

Got to catch up with this rockstar @docjockzzz at #sleep2022. Fun times we’re had! @ Charlotte, North Carolina https://t.co/PCYqAfVfRC

[Rachel Markwald, PhD @R_Markwald]

Come visit us @NH_RC at our posters on Sunday covering our work to operationalize sleep technology and sleep health for the US Navy! #044 and #045 #SLEEP2022 #militaryscience #navyresearch #operational #cots

@Sleep4Sport Amy, would love to chat about a collaboration opportunity with you!

[Rachel Markwald, PhD @R_Markwald]

100%

[Andrew D. Huberman, Ph.D. @hubermanlab]

My top 3 science supported health practices.

1) Morning sunlight viewing. To set circadian rhythm, focus, mood etc.

2) 180-200min of Zone 2 (moderate) cardio per week. Cardiovascular health.

3) NSDR (Non-Sleep-Deep Rest; 10-30min, 3-7X per week). Stress mitigation, cognition.

Opportunity to work with a great team at NHRC!

[John J. Fraser, DPT, PhD, FACSM @NavyPT]

Great opportunity to work with @p_sessoms and team studying load carriage in San Diego. I ask that my #biomechanics family spread the word.

@NavyPT @CatDonahue Me too, very interested in your work!

[Rachel Markwald, PhD @R_Markwald]

@NavyPT 100% agree with you!

[John J. Fraser, DPT, PhD, FACSM @NavyPT]

I don't mind volunteering my time and talent to journals that are #OpenAccess, non-profit, or society periodicals. That said, the model needs to change.
@TenanATC - this will be your read for the week.

@BartlettsLab @NH_RC @o2xhp It’s revolutionary!

[Rachel Markwald, PhD @R_Markwald]

@NH_RC, SURFOR and USS MANCHESTER BLUE collaborate to bring @o2xhp training and education to Sailors https://t.co/U8YGGV5Xgm

Very interesting study looking at the impact of sleep deprivation for on-road driving performance between young and older people

[Anna Cai @AnnaCaiPhD]

Very happy to announce that my article looking at the impact of age on on-road driving impairment following sleep deprivation has been published in Scientific Reports! Access the article here:

Great work from everyone involved!

[Rachel Markwald, PhD @R_Markwald]

Just finished another excellent Human Performance Summit by @FusionSport. I always take so much away from these!

[humanOS.me @humanOS_me]

Subjects who wore blue-blocking glasses three hours before bedtime for two weeks showed a ~58% increase in nighttime melatonin levels. They also fell asleep 27 minutes earlier and their objectively measured sleep duration increased by 24 min.

So great to see a review paper on the cut-off point of exercise before bedtime as there are a lot of mixed results out there. Seems as if exercise completed >2h before bedtime might be that magic number.

@dyldahl @ella_walker I wish we did but our research grade actigraphs are all currently being used :/
