Oversleeping And The Risk Of Eye Diseases

New studies reveal that oversleeping is a having detrimental effect on both our health and eyesight. 


Eye doctors are warning patients not to sleep for longer than recommended, following recent reports suggesting oversleeping can lead to macular degeneration, the leading cause of blindness in the UK. 

This alarming information was reported by Doctor Rahul N. Khurana during a clinic-based, cross-sectional study. Researchers at the Northern California Retina Vitreous Associates medical practise surveyed 1,003 consecutive adult patients on their sleep histories to explore the link between sleep patterns and advanced geographic atrophy and age-related macular degeneration (AMD). A multivariable analysis was conducted to factor in age, gender and smoking history. The study concludes patients without AMD slept an average of 7.97 hours per night, compared to 8.17 hours, 9.00 hours, and 8.97 hours respectively for those with early AMD, neovascular AMD and geographic atrophy. 

We all know how vital a full night's sleep is for your overall health and well-being but the amount of sleep a person needs isn’t so simple. How much sleep you require depends on your age, activity level, general health and lifestyle habits. Although, The Sleep Foundation suggests that healthy adults should generally sleep 7-9 hours and urges those worried about their sleeping patterns to consult a physician. 

The report, Increasing Sleep Duration is Associated with Geographic Atrophy and Age-related Macular Degeneration, connects a longer sleep duration with geographic atrophy secondary to AMD. It further states morbidity may be altering sleeping patterns and therefore, additional analysis is necessary to determine the definitive impact quality and quantity of sleep has on the diseases. Patients with AMD have higher rates of depression and poorer vision, plus patients suffering with geographic atrophy often display signs of cognitive impairment independent of visual acuity. Due to these additional factors, patients may be more sensitive to dim lighting and inclined to fall asleep earlier in the evening. In our opinion, the study merits more investigation and causation cannot be implied, considering the influence each medical condition has on a person’s body and quality of life. With the research we have, do you think it’s worth deterring people from sleeping in on Saturday morning? Let us know your thoughts on Facebook and Twitter
