Why sleep matters
The NHLBI explains that sleep plays a vital role in good health and well-being, supporting brain function and physical health, including healing and repair of the heart and blood vessels.
How much sleep
The NHLBI states that adults need 7 or more hours of sleep per night. Both quantity and quality count: regular timing and uninterrupted sleep matter too.
Risks of ongoing sleep deficiency
The NHLBI links ongoing sleep deficiency to an increased risk of heart disease, high blood pressure, diabetes, obesity, kidney disease, stroke and depression.
When to seek advice
Persistent trouble sleeping, loud snoring or daytime sleepiness are worth discussing with a doctor, as they may indicate a sleep disorder.
Factors that can affect the result
