Why am I always tired? 22 medical reasons for feeling tired

Not getting enough restorative sleep

The word restorative is important because there’s a difference between just being in bed and getting some sleep, and having enough good quality sleep.There are many different kinds of sleep disorders – more than 80 in fact. Sometimes you might feel that you’re sleeping for long enough, but actually your sleep might be more disrupted or of poorer quality than you think it is.Sleep apnea is a potentially serious sleep disorder which can leave you feeling constantly tired. If you snore regularly, or if you or your partner notice any breathing difficulties at all during your sleep, you should ask your doctor about it.And it could be that like many adults in the busy modern world, you just don’t allow yourself enough time to sleep. Most adults need between 7 and 9 hours sleep a night, but many try to survive on much less.
