The body mass index (BMI) is a calculation that helps classify your weight status. A high BMI can be an indicator of high body fat. An adult with a BMI of 30 kg/ m2 or higher is considered to be obese. More than onethird of U.S. adults are considered obese. Sleep and obesity are closely related.


Adults should sleep 7 or more hours per night on a regular basis to promote optimal health.

Sleeping less than 7 hours nightly increases your risk of obesity.

Excess body weight is a major risk factor for obstructive sleep apnea.

Untreated sleep disorders such as sleep apnea also can contribute to weight gain.

Am I At Risk ?

Your obesity risk is higher if you are inactive and eat an unhealthy diet. Healthy sleep also helps your body maintain a healthy weight. You are more likely to be obese if you sleep less than 7 hours nightly. Obstructive sleep apnea and other sleep disorders also can contribute to weight gain.


Your “energy balance” plays a vital role in preventing excess weight gain. The goal is to balance the calories you eat and drink with the calories you burn through physical activity.

Healthy sleep helps your body maintain its energy balance. Ongoing sleep loss causes changes in your body’s hormone levels. These changes can increase hunger and cause you to crave junk food. Sleep loss also causes fatigue and sleepiness, which can result in reduced activity.

Excess body weight is a major risk factor for obstructive sleep apnea. As a result the risk of sleep apnea is much higher in people who are obese. Sleep apnea also becomes more severe as your BMI increases.
Untreated sleep disorders such as sleep apnea can disturb your sleep. Poor quality sleep can disrupt your energy balance and contribute to weight gain. Other common sleep disorders include chronic insomnia, restless legs syndrome and shift work disorder.


It is important to treat any sleep disorder that disrupts your sleep. Treating obstructive sleep apnea is especially important. Weight loss is one strategy to reduce the severity of sleep apnea. Try to lose weight and maintain a BMI of less than 25 kg/m2. But weight loss alone is unlikely to cure your sleep apnea. So weight loss should be combined with another sleep apnea treatment.
The most common treatment for obstructive sleep apnea is continuous positive airway pressure therapy (CPAP). CPAP therapy provides airflow through a mask worn at night. This airflow increases the air pressure in your airway to keep it open, and restores normal breathing.
In people with severe obesity, CPAP sometimes is combined with bariatric surgery. This type of surgery makes changes to your digestive system to help you lose weight.
