Excessive sleep plus prolonged sitting takes nearly as many years off of your life as drinking and smoking.
Not getting enough sleep is a huge problem for many of us, but is it possible to get too much sleep? Yes. Especially if you also sit too much during the day. When it comes to sleep, you really can get too much of a good thing.
A recent study found that sleeping more than nine hours a night, especially when paired with too much sitting during the day, may be nudging you toward an early death.
The Australian study, which focused on adults aged 45 and up, involved a variety of behaviors, including smoking, high alcohol intake, poor diet, physical inactivity, prolonged sitting, and unhealthy (short/long) sleep duration. During six years of follow-up of 231,048 participants, 15,635 deaths were registered.
Combinations involving physical inactivity, prolonged sitting, and/or long sleep duration and combinations involving smoking and high alcohol intake had the strongest associations with all-cause mortality.
If you sleep too much, sit too much (more than seven hours a day), and aren’t particularly active (less than 150 minutes a week of exercise), you’re more than four times as likely to die as someone without those habits
