It's 3 a.m. "Mommy, can I sleep with you?" What you respond with in your sleepy stupor may have an impact on your child's risk of becoming overweight.

"Living against the clock," forced into a schedule because of a job or other responsibilities that conflicts with your natural internal clock, may be contributing to weight gain.

Too little sleep or too much poor quality sleep can hurt more than your energy levels - it can also hit your waistline. If you're not getting enough sleep, you may be trading Z's for pounds.

It's not just how much sleep you get that plays a part in your health - it's also when you sleep. An out-of-whack biological clock can mean poor health and higher risk of disease.

That midnight snack you're stealing while you're struggling to get back to sleep may satisfy late night hunger - but it may also be extra calories your body doesn't need.

If you're feeling hungrier than usual, take a look at your sleeping habits - are you getting enough sleep? If not, that may be the reason for the extra appetite.

Staying up until the wee hours of the morning may potentially lead to your weight to increase. Sleep disorder researchers exploring the relationship between the circadian timing of sleeping, eating and body mass index (BMI) report that this up and down relationship was studied for the first time in the United States.

Insufficient and disorganized sleep puts kids at higher risk of developing obesity and other health conditions, which may be able to be mitigated by "catch up" sleep on weekends and holidays.
