Obstructive sleep apnea affects an estimated 20% of the population, and if untreated it has negative effects on cardiac and metabolic health as well as quality of life. If the condition is moderate or severe, a CPAP machine is the first-line treatment, but there is less consensus about treatment of mild OSA.
The body’s circadian rhythm controls our sleep-wake cycle, so an irregular rhythm can negatively affect sleep and proper functioning, which can lead to health problems including mood disorders. The tendency to rise early or stay up late is genetically determined, but you may be able to adjust your life to better match your circadian rhythm.
Millions of Americans have trouble sleeping, a factor that is key to cardiovascular health. Two recent studies examined the relationship between sleep and heart health, and between sleep and dietary choices.

Using a CPAP machine is beneficial for people with obstructive sleep apnea, but if the machine isn’t kept clean it could lead to an illness. There are sanitizing systems available, but cleaning the parts by hand is just as effective.
Trying to make up for not getting enough sleep during the week by sleeping longer on weekends has been found to have negative effects such as weight gain, expending less energy, and increased calorie intake during evenings.
