If you are someone who doesn't get much sleep, or someone who sleeps too much, then you are at a high risk of glaucoma, a common eye condition that affects millions of people and can lead to blindness, according to a decade-long study. Snoring, daytime sleepiness and insomnia can also increase the risk of the same.

Scientists have been trying to understand the long-term implications of poor sleep and as part of the study, they roped in 400,000 people in the UK. It was the world’s first large prospective cohort study to understand sleep behaviours and patterns and glaucoma.

The results were published in the journal BMJ Open. It suggests that people with unhealthy sleep patterns have an increased risk of developing glaucoma which can lead to loss of vision if not diagnosed and treated early. Glaucoma will likely affect 112 million people worldwide by 2040, Guardian reported.

“Snoring, daytime sleepiness, insomnia, and short/long duration, individually or jointly, were all associated with the risk of glaucoma,” the team concluded.

The researchers said that the study highlights the importance of healthy sleep patterns and of eye tests among those suffering from chronic sleep disorders. Sleep therapy can also help such people who are at risk of developing glaucoma, the researchers said.

“These findings underscore the need for sleep intervention for individuals at high risk of glaucoma as well as potential ophthalmologic screening among individuals with chronic sleep problems for glaucoma prevention.”

While never has any direct cause of glaucoma been established, previous studies cite that poor sleep might be a possible reason. The latest study aimed to further explore the relation between the two under which 409,053 people aged 40 to 69 were recruited between 2006 and 2010.

Data about their sleep patterns and whether or not they had developed glaucoma was collected. 8,690 cases of glaucoma were identified in the follow-up period of almost 11 years.

The researchers found that those who snored and complained of daytime sleepiness carried an 11 per cent increased risk of glaucoma as compared to people with a healthy sleep pattern. On the other hand, insomnia and sleeping too much or too little was linked to a 13 per cent increased risk.

Sleeping too little or too much puts you at increased risk of glaucoma, says study

How long you sleep could indicate how healthy your brain is. According to a study published on Monday in the journal JAMA Neurology, sleep patterns in adults determine brain health and sometimes even indicate early signs of diseases like Alzheimer's and Dementia.&nbsp; 
 
Disrupted sleep is common in late life, the study authors wrote, and associated with changes in cognitive function -- the mental capacity for learning, thinking, reasoning, problem-solving, decision-making, remembering, and paying attention.&nbsp; 
 
Age-related change in sleeping patterns have also been linked to early signs of Alzheimer's disease, depression as well as cardiovascular diseases. 
&nbsp; 
The authors of the study investigated possible associations between self-reported sleep duration, demographic and lifestyle factors and subjective cognitive functions and participation levels of beta-amyloid.&nbsp; 
 
The study investigated the sleeping patterns of certain adults and reported that those who had short sleep duration - basically sleeping six hours or less- had elevated levels of beta-amyloid, which 'generally increases' risk of dementia.&nbsp; 
 
The study was in comparison to participants who reported normal sleep duration, which the study authors defined as seven to eight hours of sleep per night. 
 
The older adults with inadequate sleep performed comparatively worse on tests for assessing cognitive abilities, including orientation, attention, memory, language and visual-spatial skills; and identifying mild dementia. 
 
The study though also explained the side effects of too much sleeping and associated it with lesser executive function although those people did not have elevated beta-amyloid levels.&nbsp; 
 
The main takeaway from the study remains that one must maintain a healthy sleep late in life. People who get little sleep or too much sleep tend to have a higher body mass index and also more depressive symptoms. Both short and long sleep might have different underlying disease processes.&nbsp;

Change in age-related sleep pattern could be early signs of dementia, states new study

A new study explored the significant benefits of later school start times for middle and high school students` sleep schedules. 
 
The findings of the study were published in the journal `Sleep`. Sleep is essential to a student`s overall health, social development, and academic achievement, yet lack of sleep is common among children and adolescents. Biological changes to sleep cycles during puberty make falling asleep early difficult for adolescents. This, coupled with early school start times, means that students often end up with insufficient sleep. 
 
Approximately 28,000 elementary, middle, and high school students and parents completed surveys annually, before changes to school start times and for two years afterward. Participating elementary schools started 60 minutes earlier, middle, 40-60 minutes later, and high school started 70 minutes later.Student and parent surveys separately asked about students` typical bedtime and wake time on both weekdays and weekends. The surveys also asked respondents to report on students` quality of sleep and their experience of daytime sleepiness. 
 
Researchers found that the greatest improvements in these measures occurred for high school students, who obtained an extra 3.8 hours of sleep per week after the later start time was implemented. 
 
More than one in ten high school students reported improved sleep quality and one in five reported less daytime sleepiness. The average "weekend oversleep," or additional sleep on weekends, amongst high schoolers dropped from just over two hours to 1.2 hours, suggesting that with enough weekday sleep, students are no longer clinically sleep deprived and no longer feel compelled to "catch up" on weekends. 
 
Likewise, middle school students obtained 2.4 additional hours of sleep per week with a later school start time. Researchers saw a 12 per cent decrease in middle schoolers reporting daytime sleepiness. The percent of elementary school students reporting sufficient sleep duration, poor sleep quality, or daytime sleepiness did not change over the course of the study. 
 
The benefits of later start times were similar across racial and socioeconomic groups, but survey results indicated differences in weekday bedtimes. The authors encourage steps to be taken to "identify and ameliorate systemic factors that contribute to these differences," recommending education programs developed in partnership with families to ensure that guidance for adjusting bedtimes and increasing sleep opportunities are sensitive to sociocultural and environmental factors. 
 
Previous studies have not concurrently considered the impact of changing start times on sleep for students from Kindergarten through 12th grade, a key factor in policy outcomes due to the need for school districts to stagger start times to accommodate transportation schedules. 
 
"This study is remarkable due to the large sample size, the inclusion of elementary and middle school students, the two-year follow-up, and both student and parent report. It also provides the strongest evidence to date that moving elementary school start times to 8:00 am caused no significant negative effect on student sleep or daytime sleepiness. As students return to in-person learning, it is important for districts to consider healthy start times for all students," the authors concluded.

Delay in school start times let students get adequate sleep: Study

Our sleep patterns are affected by the pushes and the pulls of moon tides, as per the latest study published in Science Advances.

The findings of the study reflect that in the days leading up to the full moon, people go to bed later and sleep less. A lunar cycle takes 29.5 days to complete.

Changes in each participant’s sleep duration across the lunar cycle ranged from 20 to more than 90&nbsp;min and did not differ considerably between groups.

The&nbsp;participants of the study live&nbsp;in environments&nbsp;ranging from a rural setting with and without access to electricity in indigenous Toba/Qom communities in Argentina to a highly urbanised postindustrial setting in the United States.

Sun and moon data for the Ingeniero Juárez region through the dates of recording were obtained from NASA’s Jet Propulsion Laboratory HORIZONS Web-Interface

It is primarily moonlight available during the first hours of the night that is more likely to drive changes in the onset of sleep. In contrast, moonlight late in the night, when most individuals are typically asleep, should have little influence on sleep onset or duration.

While the sun is the most important source of light and synchronizer of circadian rhythms for almost all species, the moonlight also modulates nocturnal activity in organisms.

Moonlight is so bright to the human eye that it is entirely reasonable to imagine that, in the absence of other sources of light, this source of nocturnal light could have had a role in modulating human nocturnal activity and sleep.

Before the availability of artificial light, the moonlight was the only source of light sufficient to stimulate nighttime activity; still, evidence for the modulation of sleep timing by lunar phases is controversial.

The study shows that sleep starts later and is shorter on the nights before the full moon when moonlight is available during the hours following dusk.&nbsp;

Both the duration and the time of sleep onset showed a clear modulation throughout the moon cycle that was evident in the whole population, as well as in the individual communities.&nbsp;

The study predicts that&nbsp;in communities without access to electricity, moonlit nights would be associated with increased nocturnal activity and decreased sleep.

The amplitude of the lunar phase effect on sleep parameters appears to be stronger the more limited the access to electric light is.&nbsp;
