If your kids are actually at risk of thrombosis after 5 hours in the car they have some extremely serious medical condition, like Karo syrup for blood or something. (For real, DVTs happen to obese bed ridden patients in their 40s, not healthy active kids). I just don't think 'sit down and shut up' for a couple days in the car would be that horrible. I could see doubling your travel time for bathroom breaks etc but 5 hours a day? that seems like a very part time effort, more of a hotel vacationing across the country than a road trip.

False.

The scientists began by testing baseline arterial function in the nine girls, using ultrasound and blood pressure cuffs. All of the girls had healthy arterial function.

Then half the girls sat in comfortable beanbag chairs in the lab for three uninterrupted hours, playing on iPads and watching movies. If they needed to use the bathroom, a researcher wheeled them there.

The other girls also sat for three hours, but at the start of each hour, they got up and went over to a row of stationary bicycles in the lab and rode them gently for 10 minutes before plopping back onto their beanbags.

Afterward, all of the girls’ arteries were re-examined.

A few days later, the girls all repeated the experiment, but now sitting uninterrupted if they had ridden a bike before, and vice versa.

The results should give pause to any of us who, as parents, beg our kids to keep still.

After the girls had reclined for three uninterrupted hours, their arteries no longer functioned as well as they had at the start. In fact, the girls now showed “a profound reduction in vascular function,” the scientists wrote, with arterial dilation — the normal and healthy widening of blood vessels — falling by as much as 33 percent.

"For perspective,” Dr. McManus said, in adults, a sustained 1 percent decline in vascular function “has been shown to increase cardiovascular disease risk by 13 percent.”

Thankfully, the girls’ arteries returned to normal rapidly, since those who had sat for three uninterrupted hours displayed typical vascular function when they were retested on their return trips to the lab for their second sessions.

Equally encouraging, when the girls broke up their sitting time with easy cycling, they showed no decline at all in vascular function.

"It seems clear from our results that children should not sit for prolonged, uninterrupted periods of time,” Dr. McManus said.

While the girls’ arteries did bounce back from the uninterrupted sitting, “we don’t know what the impacts are of uninterrupted sitting day after day,” she said.

So encourage young people to stand up and move around at least every hour, she says. A stroll around the classroom or living room should help. The girls in the study pedaled “at a very easy level” when they broke up their sitting time with cycling, Dr. McManus said, suggesting that vigorous exercise is not required to keep children’s arteries healthy.

Even if whatever study the NY Times decided to quote for more viewership is rigorous enough to be meaningful what does a 33% reduction in arterial function mean practically? It means 0% risk of death 0% risk of injury and 0% risk of permanent damage in a healthy youth. So literally nothing.

read that garbage again back to yourself. it's laughable ffs.
