Oversleeping is more harmful than I ever knew.
We all know that a good nights sleep is healthy, and lack of sleep, not so much. But, the problem is that sometimes too much of a good thing can bring about a whole raft of health problems.
Problems such as:
Impaired Brain Functioning and Mental Health: Sleep is important in the brain, as the brain clears out the waste, balances neurotransmitters and processes memories at rest. Both extremes, too much and too little rest may have an effect on mood and mental health.
Degenerative Diseases
Research indicates that getting too little or too much sleep may be tied to increased Alzheimer’s disease risk factors and studies found that long sleepers may be at increased risk of developing dementia.
Depression and Mental Health
Oversleeping is considered a potential symptom of depression. While many people with depression report insomnia, approximately 1.5% tend to oversleep.
People with long sleep durations are also more likely to have chronic depression or anxiety symptoms compared to normal sleepers. A recent study also found that sleeping too little or too much seemed to increase the genetics of depressive symptoms when compared to normal sleepers, 7-9 hours a night.
Increased Pain
While many times it can seem intuitive to rest more when we’re in pain, research shows that in some cases too much sleep can worsen those symptoms. Back pain can worsen from too little activity or spending too much time in bed. Sleeping in a less than optimal position or using an old or unsupportive mattress can also make back pain worse. Combined with staying still for a long period of time, these factors mean that you could awaken with worse back pain especially when spending longer amounts of time in bed.
Oversleeping is also linked with higher rates of headaches. Referred to as a “sleep headache,” sleeping in may trigger migraines and tension headaches. The cause isn’t necessarily sleep itself, but, some studies have linked it with caffeine withdrawal or increased stress.
Impaired Fertility
In a study of Korean women undergoing in vitro therapy found that women who slept seven to eight hours had the best chances of conceiving. The moderate sleepers had the highest pregnancy rates (53%) compared to those sleeping six hours or less (46%) and those sleeping nine to eleven hours (43%). Study authors suggest sleep outside the normal range could be affecting hormones and circadian cycles, impairing fertility.
Cognition
Using data from Lumosity brain-training, researchers found that cognitive performance on three different games all peaked when people slept around 7 hours worsening with more or less rest. Other studies have also found memory impairment and decreased cognitive function with longer sleep.
Impaired Glucose Tolerance
Glucose tolerance refers to the body’s ability to process sugar, and impaired glucose tolerate is associated with insulin resistance puts you at risk factor for type 2 diabetes and heart disease.
With all of these problems, why would anybody really want to sleep that long? I started studying the problems of oversleeping when I thought that more sleep was the answer to taking more pain pills for my failed back syndrome, unfortunately, it never really worked, and may have made me a pre-diabetic.
The moral? Try not to over, or under sleep, it’s not worth the problems.
