Sleep may influence weight by affecting hormones, glucose metabolism and inflammation, say scientists. A new study has found that sleeping more than nine hours a night appears to suppress genetic factors that lead to weight gain. In contrast, getting too little sleep seems to have the opposite effect. Adding a few hours sleep to your night may prevent you from gaining weight. These new findings reveal a complex interaction between sleep and genetic factors linked to body weight.

The study found heritability of body mass index (BMI) — a measurement relating weight and height — was twice as high for short than for long sleepers.

Thus sleep well and stay healthy.
