While having the kind of night’s sleep where you sleep deeply through a hurricane, or a loud party around may sound like the dream many working-class adults would harbour, it also means a few unforeseen health issues for a few- particularly if the sleep change comes on all of a sudden, or if you find yourself more tired in the day. The optimal amount of sleep is between 7 to 9 hours. But if you’ve been sleeping like a log without a reason lately, here are few health issues you might have.

While stress is most notable for causing sleep disturbances and insomnia, in some of us it can go the other direction — and make us drop off. The phenomenon may simply be an energy-saving technique. One of the reasons that people sometimes get so wiped out and even fall asleep is that whenever you’re put up to a lot of mental tasks or physical tasks, it uses up glucose in the brain. Glucose is essentially sugar, and it gives you the energy you need." Depleted glucose means fatigue and deep sleep. If you're stressed at work and still get eight hours every night, it could be explained pretty simply: your brain's going into recovery mode.

It is a common phenomenon for people with depression to say, that “it’s difficult to get out of bed.” While part of it is psychological, studies have proven that depression does have an effect on our sleep cycle. A 2016 study claims that REM sleep begins far early for depressed individuals. So if you’re sleeping long hours with weird dreams, depression could be a possible explanation.

Oversleeping is associated with many health problems. A study done in 2015 showed that there is a link between sleeping a lot and type 2 diabetes in women. However, no light has been thrown about the cause or effect. According to the neurologist, Carl Bazill, if you’ve started sleeping longer spontaneously, it could be a reason for concern. So notice if you’re been requiring more sleep with an absence of a cause or change in medicine. If yes, it’s a good reason to visit a doctor.

A clear symptom of heart disease could be sleeping deeply despite resting for more than eight hours at a time, according to a study published in the European Heart Journal. "Both shorter (less than six hours a day) and longer (more than eight hours a day) estimated total sleep durations were associated with an increased risk" of cardiovascular issues and mortality, the study said. So, if you have a history of cardiovascular disease, and have been suddenly sleeping for what feels like a million years, it’s a notable symptom.

Amongst the other health issues, sleeping deeply for long hours could also be a symptom of hypothyroidism or an underactive thyroid. Here’s some explanation – thyroid controls the metabolism and its underperforming causes fatigue and joint paint. However, fatigue isn't the sole sign of hypothyroidism, so if you're just sleeping deeply and don't have any other symptoms, this is unlikely to be your issue
