Feel Tired All the Time? “Social Jet Lag” May be to Blame

It's practically a law of nature: If you stay out late on Friday night, you'll feel it on Saturday morning. But a new study [PDF] published in the journal Sleep suggests the repercussions of partying on the weekends last long after Monday morning rolls around. As Medical News Daily reports, “social jet lag"—what happens when someone goes to bed later on weekends than during the week—has a negative impact on overall wellbeing.

For the study, researchers looked at 984 people between the ages of 22 and 60 who responded fully to a Sleep Timing Questionnaire. Participants were asked report their sleep habits and rate their health as “Excellent," "Good," or "Fair/Poor."

They found that inconsistent sleep schedules can lead to several issues, such as fatigue and irritability. The lifestyle is connected to more serious problems as well: For every hour of social jet lag accumulated, subjects were 11.1 percent more likely to develop heart disease. People who racked up just one hour of social jet lag had a 28 percent higher chance of describing their health as ”Fair/Poor" instead of “Excellent.”

Even if you sleep until noon after getting home at 4 a.m., that won’t necessarily remedy the problem. Previous studies have shown that disrupting your circadian rhythm, even if you make those hours up eventually, has nasty effects on your metabolism. So if you work a nine-to-five job during the week, you should probably stick to a reasonable bedtime on the weekends.

The 10 Most—and 10 Least—Stressed-Out States in America

When your car breaks down, your card gets declined, and your alarm fails to go off all in one week, it probably seems like your own state of stress has nothing to do with the state you happen to live in. But some states do tend to have more stressed populations than others.

To find out which ones, WalletHub analyzed 41 factors across four different types of stress—work, money, family, and health and safety—and scored each state’s collective stress level on a scale of 100. The findings don’t exactly jibe with the idea that life is slow-moving and easy-going down South: Nearly all 10 of the most-stressed states are in the South or Southwest, including Louisiana, Mississippi, New Mexico, Arkansas, Kentucky, Alabama, and Oklahoma.

Louisiana came in first with just over 57 points, ranking third for work-related stress (which covers things like average hours worked per week and unemployment rate) and second for money-related stress (think income, credit score, and housing affordability).

Residents in Alaska, which clinched the 10th spot with about 49 points, don’t seem to have much money-, family-, or health-related stress; the state landed at 46th, 36th, and 23rd for those three categories, respectively. Their work stress, on the other hand, is higher than any other state, largely due to low job security and long hours.

If you’re looking to move somewhere mellow, your best bet is the upper Midwest. Minnesota, North Dakota, South Dakota, and Iowa are the four least-stressed states in the land. Minnesota, whose stress score is less than 28, has some of the lowest poverty and divorce rates, some of the highest credit scores, and an abundance of psychologists per capita. But you don’t have to resign yourself to living in a cold climate if you want to settle down somewhere calm—Hawaii ranked seventh, and temperate Maryland rounded out the top 10.

Take a look below to see if your state is especially harried or not, and see the full list of scores here.
