Scientists have revealed why people should head to sleep at the same time every night. A study by Kings College London which involved 1,000 adults, aimed to find whether "social jetlag" (the shift between sleep patterns on work days and free days) can have an impact on health. In doing so, researchers discovered that sleeping at the same time and a healthy diet could decrease the risk of disease. They found that even a 90-minute difference in the mid-point of sleep could impact the types of bacteria in the gut. They analysed participants' sleep, blood and stool samples, and logged everything they consumed in a food diary. Those with "social jetlag" (16 per cent) appeared to have a diet filled with potatoes, crisps, chips and sugary drinks. Other studies have suggested that social jetlag is linked to weight gain, illness and mental fatigue.

"This is the first study to show that even small differences in sleep timings across the week seems to be linked to differences in gut bacterial species. "Some of these associations were linked to dietary differences but our data also indicates that other, as yet unknown, factors may be involved. "We need intervention trials to find out whether improving sleep time consistency can lead to beneficial changes in the gut microbiome and related health outcomes." Kate Bermingham, study author and senior nutrition scientist at ZOE, said: "Sleep is a key pillar of health, and this research is particularly timely given the growing interest in circadian rhythms and the gut microbiome. "[Social jetlag] can encourage microbiota species which have unfavourable associations with your health," she continued. Have your say in our news democracy.

Longtime TV producer Marty Krofft has died at age 86

The police officer who has been hailed as a hero for taking down the gunman who killed eight people after opening fire at Allen Premium Outlets in Texas has released a statement saying he’s “doing well.” Three days after the tragic shooting, the officer’s attorney, Zach Horn, released a statement on behalf of the officer to local news outlet WFAA. “He’s doing well and would appreciate privacy and he continues to process this life-altering tragedy,” the statement from Mr Horn read. In the statement, Mr Horn said the officer, who wishes to remain unidentified, “sprinted toward the high power rifle fire as everyone else ran away” to subdue the gunman. “He’s a brave servant with a gentle heart that embodies the best the law enforcement profession has to offer,” Mr Horn added. The Independent has reached out to Mr Horn for comment. The gunman, who has been identified as 33-year-old Mauricio Garcia, was taken down by the officer after killing eight people, including three children, and injuring seven others. Garcia arrived at the Allen Premium Outlets on Saturday (6 May) armed with an AR-15 style rifle, ammunition and body armour. Authorities are unsure what the motive behind Garcia’s attack was though police found he may have had ties to a far-right organisation, white supremacy and possibly neo-Nazism. The shooting is one of over 200 to have occurred in the United States this year so far. More follows.
