MEASLES OUTBREAKS IN WASHINGTON, TEXAS AND OREGON WERE PREDICTED BY SCIENTISTS A YEAR AGO

 

Outbreaks of measles have now been reported in 10 states across the U.S. In Clark County, Washington, officials say there have been 49 confirmed cases, 34 of which were in children aged 10 or under. In Harris County, Texas, three measles cases have been reported, including two boys under 2.

In a study published almost a year ago, scientists identified "anti-vaxx hot spots"—and the areas flagged include those where cases are now being reported.

One of the driving forces behind the current measles outbreak is falling vaccination rates, with parents failing to ensure their children have the two doses of the measles-mumps-rubella (MMR) vaccine, as recommended by the Centers for Disease Control and Prevention (CDC).

This group includes “anti-vaxxers,” who erroneously believe vaccines are dangerous to their children, and parents who face barriers in obtaining the shots—in some states, it takes more time, effort and money to vaccinate their children than it does to get a nonmedical exemption. These NMEs, which are available in 18 states, are fairly easy to get. In Oregon, for example, all parents have to do is “watch an online education module and submit a certificate of completion.”

How Sleep Strengthens Your Immune System

 

Numerous studies have reported the benefits of a good night’s sleep, and now researchers from Germany have found that sound sleep improves immune cells known as T cells.

“T cells are a type of… immune cells that fight against intracellular pathogens, for example virus-infected cells such as flu, HIV, herpes, and cancer cells,” Stoyan Dimitrov, PhD, told Healthline.

The study found a new mechanism through which sleep can assist the immune system.

“We show that the stress hormones adrenaline and noradrenaline and pro-inflammatory molecules prostaglandins inhibit the stickiness of a class of adhesion molecules called integrins,” Dr. Dimitrov said. “Because the levels of adrenaline, noradrenaline, and prostaglandins are low during sleep time, the stickiness of the integrins is stronger. This stickiness is important because in order for T cells to kill virus-infected cells or cancer cells, they need to get in direct contact with them, and the integrin stickiness is known to promote this contact.”

When cells in the body recognize a virally infected cell, they activate integrins, a sticky type of protein, that then allows them to attach to and kill infected cells.

The researchers compared T cells from healthy volunteers who either slept or stayed awake all night.

They found that in the study participants who slept, their T cells showed higher levels of integrin activation than in the T cells of those who were awake.

The findings indicate that sleep has the potential to improve T cell functioning. For people who get poor sleep, stress hormones may inhibit the ability of T cells to function as effectively.

Less than five hours sleep per night on a regular basis is associated with higher mortality, and having less than seven hours sleep for three nights in a row has the same effect on the body as missing one full night of sleep.

Poor sleep can increase inflammation, blood pressure, insulin resistance, cortisol, weight gain, and cardiovascular disease, as well as decrease blood sugar regulation.

Despite numerous studies proving the negative health impacts of poor sleep, experts say many people still don’t prioritize getting enough sleep.

New Parents Don’t Get Enough Sleep for Six Years After a Child Is Born

 

Those first three months with a newborn can be rough, but researchers say sleep deprivation is an issue with parents for years. New parents are sometimes shocked to discover how little sleep they get in the first six months after a baby is born. They might also be discouraged to learn that their sleep patterns might not return to normal until that newborn is ready for kindergarten.

A new study published in the journal Sleep found that both parental sleep satisfaction and sleep duration sharply declined after childbirth, hitting their lowest point when a baby is 3 months old.

Women’s sleep duration and quality were far more affected than men, whether or not they breastfed their child. Women lost an average of one hour of sleep nightly compared to what they got prior to pregnancy, while men lost about 15 minutes of sleep per night.

Even four to six years after childbirth, mothers were getting 20 minutes less sleep per night than before they became pregnant, while fathers were still getting 15 minutes less sleep.

“The short-term effects of childbirth on parental sleep is well known. Our study just confirmed these effects,” Lemola told Healthline. “However, it was largely unexpected to find decreased sleep duration and sleep satisfaction six years after birth.”

Sleep was more affected among first-time parents than among parents with more than one child.

The findings were based on interviews of 4,659 parents who had a child between 2008 and 2015.

“While having children is a major source of joy for most parents, it is possible that increased demands and responsibilities associated with the role as a parent lead to shorter sleep and decreased sleep quality even up to six years after birth of the first child,” said Lemola.

Lemola said that future research would be required to determine how parents can cope with sleep loss and regain their sleep patterns sooner.
