Obstructive Sleep Apnea and Overall Health
What Is Obstructive Sleep Apnea?
Sleep health is whole-person health
The American Heart Association recognizes sleep health as an important part of overall health and well-being. Quality sleep supports physical, mental and emotional health. Research continues to show links between sleep and overall health and understanding these connections can help people, caregivers and healthcare professionals work together to support better health outcomes.
When breathing is disrupted during sleep, the effects can go beyond feeling tired the next day. Obstructive sleep apnea (OSA) is a common sleep disorder that often goes undiagnosed. It is defined as repeated pauses in breathing during sleep that can reduce airflow. OSA can affect sleep quality and may affect:
- Heart health
- Metabolic health (how the body stores, creates and uses energy)
- Brain function
- Daily functioning
- Quality of life
Understanding Sleep Health
Healthy sleep supports heart health, brain health, energy levels and overall well-being.
Sleep helps the body and brain recover, repair and function at their best.
Healthy sleep supports:
- Heart health
- Metabolic health
- Mental well-being
- Immune health
- Energy levels
Healthy sleep habits may include:
- Keeping a consistent sleep schedule
- Limiting screen time before bed
- Creating a comfortable place to sleep
- Staying physically active
- Limiting alcohol and tobacco use
Like healthy eating and physical activity, sleep is a key part of overall wellness.
