Bad sleep habits linked to chronic diseases
The number of hours that people sleep each night could affect their risk of developing certain chronic diseases, such as diabetes, heart disease, obesity and anxiety, according to new research.
While many studies have found that getting too little sleep has a negative impact on health, this study from the Centers for Disease Control and Prevention (CDC) suggests that getting too much sleep–which the study defined as 10 or more hours—can be just as bad as getting too little sleep, or six or fewer hours.
In the study, published in the journal SLEEP, researchers examined data on more than 54,000 people ages 45 and older. Participants who slept an average of six hours a night had more coronary heart disease, stroke, diabetes, obesity and mental distress than “optimal sleepers”—people who slept between six and nine hours a night.
But the findings also showed that those who slept for 10 hours or more a night had even more chronic diseases than people who slept too little.
Getting an “optimal” amount of sleep—between seven and nine hours, according to the researchers-- is especially important for people who already have a chronic condition. For people who have both a chronic disease and a sleep condition, such as apnea or insomnia, seeking proper treatment is crucial.
