Here’s something to tell yourself when you reach for that 11 p.m. pint of whatever: This pint will hurt my job performance tomorrow. And it will, says a new study in the Journal of Applied Psychology out of North Carolina State University.
Key findings: Yes, crappy eating at home leads to crappy job performance at work the following day.
Researchers tracked the food and drink intake of 97 employees for 10 days, alongside job performance reports. Those who ate unhealthfully in the evening and night—” unhealthy” is defined here as participants who felt they’d consumed too much food, drink, or junk food—were likely to report emotional strain in the morning, such as feelings of stress and shame, alongside physical symptoms such as headaches, stomachaches, and diarrhea.
