You can help prevent obstructive sleep apnea if you:
- Don't use alcohol and medicines, such as sleeping pills and sedatives, before bed. These can relax your throat muscles and slow your breathing.
- Eat sensibly, exercise, and stay at a healthy weight.
- Quit smoking. The nicotine in tobacco relaxes the muscles that keep the airways open. If you don't smoke, those muscles are less likely to collapse at night and narrow the airways.
