A Democratic congressman deleted a tweet posted late Friday that described the killing of Tyre Nichols as a result of "white supremacy" — even though all of the police officers charged in relation to his death are Black.

"Doesn’t matter what color those police officers are," Rep. Maxwell Frost, D-Fla., tweeted on Friday evening.

"The murder of Tyre Nichols is anti-Black and the result of white supremacy," he added.

The tweet was later deleted.

The tweet had come shortly after the release of four videos from the Jan. 7 traffic stop that preceded the death of Tyre Nichols, who spent three days in the hospital before succumbing to his injuries, according to authorities. 

The brutal encounter led to the firing of five Memphis police officers, who now face numerous charges, including murder. Hours after the department released the videos, Shelby County Sheriff Floyd Bonner Jr. announced that he was relieving two deputies of duty and launching an internal investigation of his own.

The footage, taken from body cameras as well as a nearby street camera, shows Nichols attempting to flee from the officers, who chase him down, tase him, repeatedly curse at him, punch and kick him, spray him with pepper spray and leave him bloodied and dazed.

Frost's tweet was one of a number of attempts to present the death of Nichols as a racial issue.

"If you think the Memphis police officers had to be white in order to exhibit anti-Blackness, you need to take that AP African American Studies course [Florida Gov.] Ron DeSantis just banned," Former Rep. Mondaire Jones, D-NY, tweeted.

"Yes, the police officers who brutally murdered him must be held accountable. But even their conviction on the strongest possible charges cannot bring Tyre back. We must do everything in our power to end police violence against people of color," Sen. Bernie Sanders, I-Vt., said.

Meanwhile, CNN commentator Van Jones attempted to make the case that the former Memphis police officers responsible for the death of Nichols "still might have been driven by racism."

"From the King beating to the murder nearly three years ago of George Floyd, American society has often focused on the race of the officers — so often White — as a factor in their deplorable acts of violence," Jones wrote. "But the narrative ‘White cop kills unarmed Black man’ should never have been the sole lens through which we attempted to understand police abuse and misconduct. It’s time to move to a more nuanced discussion of the way police violence endangers Black lives."

"At the end of the day, it is the race of the victim who is brutalized — not the race of the violent cop — that is most relevant in determining whether racial bias is a factor in police violence. It’s hard to imagine five cops of any color beating a White person to death under similar circumstances. And it is almost impossible to imagine five Black cops giving a White arrestee the kind of beat-down that Nichols allegedly received," Jones said.

Approximately 20% adults in the U.S. may be taking medication — either occasionally or regularly — to fall or to stay asleep, according to data recently released in January.

The Centers of Disease Control and Prevention (CDC) found that approximately 8.4% adults in the U.S. take medication either every day or most days to stay or fall asleep, according to a National Center for Health Statistics data brief.

An additional 10% of adults likely also take sleep medication "some days" to either fall or stay sleep.

"Recent data that up to 20% of Americans use medications to help them sleep is alarming," said Dr. Baljinder S. Sidhu, a pulmonologist and sleep specialist who is the co-owner of Pacific Coast Critical Care Group in Southern California.

He added that it's alarming "especially in the face of growing evidence of harm or mortality associated with such medications, even when used in the short term."

The study results came from a health survey that asked participants if they took sleep medication during the past 30 days.

"In 2020, 6.3% of adults took sleep medication every day in the last 30 days, 2.1% took medication most days, 10.0% took medication some days and 81.6% never took medication," the report said.

"Among all adults, sleep medication use increased with increasing age, decreased with increasing income, and was higher among non-Hispanic White adults compared with adults of other race and Hispanic-origin groups," the report noted regarding its key findings.

THE BEST FOODS FOR A GOOD NIGHT'S SLEEP

The researchers analyzed data from the 2020 National Health Interview Survey of adults 18 years and older to find the percentage of men and women who used medication for sleep.

Sleep medication was defined "as taking any medication to help fall or stay asleep most days or every day in the past 30 days, by selected socio-demographic characteristics," the report said.

The study found that adults took medication for sleep with increasing age — "from 5.6% of those aged 18–44, to 10.1% of those aged 45–64, and 11.9% of those aged 65 and over," the report said.

Women were more likely to take sleep medication than men across all age groups.

White men were most likely to use sleep medications compared with Asian men — who were least likely.

Men with the highest family incomes were least likely to use sleep medication compared with lower and middle-income groups.

"Hispanic men were more likely than non-Hispanic Asian men to take sleep medication, while among women, these groups were not different," the report noted.

The CDC notes on its website that there are three common problems with sleep.

The common issues are: 1) difficulty going to sleep; 2) difficulty staying asleep; and 3) waking up too early.

The human body has an internal clock that resets every day by the sun’s light and dark cycle, per the CDC.

This clock has a 24-hour circadian rhythm that helps us fall asleep and wake up.

A hormone called melatonin peaks in our body early in the morning, around 2 a.m. to 4 a.m. — and then production stops later in the morning, according to the CDC’s website.

"Normally, the body increases [the] melatonin level in the evening one to two hours before usual bedtime," the CDC added.

It’s possible to purchase melatonin in supplement form or as a prescription, but the CDC warns it must be taken at the right time for your sleep cycle — otherwise, it could shift the internal clock in the wrong direction or have no effect.

The Sleep Foundation notes that sleep medications should not be first line for treating insomnia.

"Because they can be addictive and they often come with side effects, the American College of Physicians and the American Academy of Sleep Medicine recommend using other techniques before turning to pharmaceutical sleep aids," according to the Sleep Foundation’s website.

"Non-medication/prescription treatments such as cognitive behavior therapy (CBT), light therapy when appropriate, etc. should be the pursued prior to resorting to sleep medications," Dr. Sidhu of California noted.

Sidhu noted that research has estimated a 1.5 to fivefold higher risk of death from sleep medications. 

"Furthermore, sleep medications have even been associated with poor daytime functioning and disruption of normal sleep architecture (our normal sleep pattern)," he said.

These medications "can provide a false sense of what normal sleep should feel like, which further contributes to a belief that sleep is not restorative unless they are in a medicated coma state."

This may lead individuals to seek out stronger medications for "quality" sleep, he noted.

"One such extreme case, in which an anesthetic was utilized to address insomnia for a celebrity, resulted in his death."

Sidhu recommends first a thorough evaluation for insomnia.
