A PNAS study found that sleeping in a room with 100 lux of overhead light abnormally elevates morning glucose levels.
"There's a beautiful study published in Proceedings of the National Academy of Sciences that showed that people who sleep in a room with an overhead light of 100 lux, which is extremely dim, show abnormally elevated morning glucose levels." (said at 0:11:13)
No published record matching the claim that a PNAS study found sleeping in a room with 100 lux of overhead light abnormally elevates morning glucose levels was located; this does not prove the claim false.
Tart cherry consumption increases apigenin levels.
"Now, I would add to that um saffron, um tart cherry, we know can increase apigenin, apigenin and chamomile extract." (said at 0:18:38)
No published record matching the claim that tart cherry consumption increases apigenin levels was located; this does not prove the claim false.
Low-dose lithium (1 mg, such as lithium orotate) promotes sleep onset and increases deep sleep.
"There's some interesting data, although people should talk to their doctor, about taking very low-dose 1 milligram lithium, I think it's the orotate form, in order to encourage the ability to fall asleep and get more deep sleep." (said at 0:27:31)
No published record matching the claim that low-dose lithium (1 mg, such as lithium orotate) promotes sleep onset or increases deep sleep was located; this does not prove the claim false.
Looking upward activates the autonomic nervous system to increase alertness, whereas looking downward and lowering the eyelids engages parasympathetic circuits that promote sleepiness.
"When you look up, it's essentially activating the arm of your autonomic nervous system which makes you more alert. It's wild. And eyelids open. It's really interesting. And when you look down and bring your eyelids down, you're actually pedaling on the circuits that promote sleepiness or at least that are more parasympathetic." (said at 0:34:36)
No published record matching the claim that upward gaze directly activates the sympathetic arm of the autonomic nervous system to increase alertness, or that downward gaze and lowering the eyelids selectively engages parasympathetic circuits to promote sleepiness, was located; this does not prove the claim false.
Superficial lymphatic vessels run so close to the skin surface that excessive massage pressure collapses and occludes them.
"It feels like nothing. But the lymphatic vessels run so superficially that if you press on them too hard, you actually cinch them off." (said at 0:37:38)
No published record matching the claim that excessive massage pressure collapses and occludes superficial lymphatic vessels was located; this does not prove the claim false.
Puffiness and bags under the eyes following acute sleep deprivation are caused by the accumulation of lymphatic fluid.
"The bags under people's eyes, that's buildup of lymph, okay? It's, you know, a couple hours later, that's what that is. It's buildup of lymph" (said at 0:45:00)
No published record matching the claim that under-eye bags or puffiness following sleep deprivation are caused by the accumulation of lymphatic fluid was located; this does not prove the claim false.
Sleep deprivation causes an observable change in the color around the iris due to the accumulation of lymph in the anterior chamber of the eye.
"there's actually a change in color of the eyes that has to do with the accumulation of lymph in the anterior chamber of the eye." (said at 0:45:50)
No published record matching the claim that sleep deprivation causes an observable change in eye color due to lymph accumulation in the anterior chamber of the eye was located; this does not prove the claim false.
In China, experiments have been conducted where children stare at a focal point on a wall for several minutes before starting their work to improve focus.
"Now, in China, they're doing some very interesting experiments of having kids stare literally at a at a focal point on the wall for a number of minutes before beginning their work." (said at 1:01:15)
No published record matching experiments in China where children stare at a focal point on a wall before schoolwork to improve focus was located; this does not prove the claim false.
Forward locomotion combined with lateral eye movements on a walk significantly downregulates anxiety.
"a locomotion with lateral eye movement on a morning walk downregulates anxiety big time. And not if you're looking at your phone." (said at 2:18:15)
No published record matching the claim that forward locomotion combined with lateral eye movements during a walk downregulates anxiety was located; this does not prove the claim false.
Creatine is administered clinically following transient ischemic attacks (TIAs) for neuroprotection.
"They're giving people creatine after TIAs now. It doesn't surprise me, neuroprotective." (said at 2:44:16)
No published record matching the claim that creatine is administered clinically following transient ischemic attacks (TIAs) for neuroprotection was located; this does not prove the claim false.
Exposure to long-wavelength light can mitigate the cellular toxicity and damage caused by blue light.
"long-wavelength light can really offset some of the toxicity of of blue light, but it's not just about sleep." (said at 2:49:23)
No published record matching the claim that exposure to long-wavelength light can mitigate or offset cellular toxicity and damage caused by blue light was located; this does not prove the claim false.
Unverified means no publication matching the claim was located; it does not prove the claim false. Spotted an error? See the corrections policy - disputes from the people quoted are prioritized.
