#Tired all the Time? Common Lifestyle and Health #Causes of Fatigue

Perhaps the most obvious reason you might be feeling tired is that you are not getting adequate sleep. Sometimes this results from bad sleep habits. “Staying up late at night, too much screen time — those habits can definitely affect people’s energy level,” says Dr. Tung. People who have work schedules that require staying up all night may also have difficulty getting a consistent block of time to achieve restful, deep sleep. But inadequate sleep can also be caused by insomnia or poor sleep quality triggered by stress, or sleep disorders, such as obstructive sleep apnea. If you have obstructive sleep apnea, tissues in your throat relax during sleep, periodically blocking your airway, causing breathing interruptions that disrupt sleep.
