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

Very interesting study looking at the impact of sleep deprivation for on-road driving performance between young and older people – at San Marcos, CA
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:

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.
New review bit.ly/3ogUzzu concludes that when exercise ends 2 h before bedtime, there are sleep benefits (faster sleep onset & ⬆️ sleep duration) but when exercise ends < 2 h before bedtime, sleep was negatively impacted (slower sleep onset & ⬇️ sleep duration)
I’d like to share our lab’s latest work out of the Warfighter Performance Department at @NH_RC academic.oup.com/sleep/advan… – at San Marcos, CA

Bill Dement died last night. He was the inspiration for my putting together the very first Principles and Practice of Sleep Medicine. Without him there would be no sleep field.

A high heat capacity mattress lowered core body temperature (CBT) & improved sleep quality (11 min less of being awake) in elite rugby players after a match.
3 min whole body cryotherapy had no impact on CBT or sleep architecture. journals.lww.com/acsm-msse/A…
