Binge-watching on the couch

One more episode, slumped into the cushions, snack within reach.

Hours on the couch are some of the least active hours of the day. A slouched, sunken posture loads your neck and back, mindless snacking adds up, and the next episode often wins over bedtime. Breaking it up and setting an end point keep a relaxing habit from taking more than it gives.

01

Long stretches of not moving

Watching TV is linked to more health risk than other kinds of sitting, partly because the stretches are long and unbroken. Long sitting is tied to higher risk of heart disease, type 2 diabetes and early death, even in people who exercise.

02

Slumped back and neck

Sinking into soft cushions rounds your lower back, and propping your head on an armrest bends your neck to the side for long periods. Stiffness when you get up is common.

03

Mindless snacking

Eating while watching makes it easy to lose track of how much you have had, and snacks on the couch tend to be salty, sweet and highly processed. Over time this adds weight and sodium.

Pushed-back bedtime

Autoplay makes it easy to keep going well past when you meant to sleep. Regularly cutting sleep short is linked to worse mood, focus, and long-term health.

When to see a professional

Talk to a doctor if you notice you have lost interest in most things beyond watching, if low mood lasts more than two weeks, or if back pain spreads down a leg or lasts more than a few weeks.
