Can you “catch up” on sleep?

Woman sleeping - timely sleep may be an essential part of maintaining a healthy weight.

Can you use the weekends to “catch up” on missed sleep?

A new study published in the journal Current Biology seems to indicate that you can’t.[1]

In this study, a number of participants were split up into three groups. Two groups slept only 5 hours per weeknight, and the other slept 9 hours per night.

One group that slept less during the week were allowed to sleep as much as they wanted on the weekend – to “catch up”.

This didn’t prevent that group from gaining weight – due to metabolic dysregulation from the lost sleep.

The researchers concluded that: “Weekend recovery sleep did not prevent weight gain or reduced insulin sensitivity”

Insulin sensitivity is an important factor in maintaining weight. A reduced sensitivity to insulin means your body requires more insulin in your blood stream, and blood sugar tends to be higher.

Further, people with reduced insulin sensitivity have a higher chance of developing metabolic diseases such as diabetes, obesity and heart disease.

What does this all mean?

It means that getting a good night’s rest, in a timely fashion, may be essential to maintaining a trim waistline and your health.
