though i post this here... so how does this relate to orgasm/ porn addiction? does orgasm/addiction increases dopamine release at orgasm but causes a long lasting drop in dopamine release- 2weeks cycle? does abstinence produce higher levels of dopamine?
i know i had good vision until i got a computer.... and stopped spending time outdoors..
Exposure to sunlight could be a critical factor in stopping children from becoming short-sighted, Australian researchers have found.
Dr Ian Morgan, of the Australian Research Council Centre of Excellence in Vision Science, says there has been a dramatic escalation in myopia rates in East Asia during the past 30 years.
"What children are doing in Australia at the moment seems to be right," he says.
Morgan believes the exposure to sunlight cuts myopia rates by encouraging the release of dopamine.
Dopamine is known to inhibit eye growth and myopia is a condition caused by excessive eye growth.
Morgan says while they will begin experiments to assess this theory, the findings are concrete enough to inform public health policy.
"The findings provide a means of prevention and are enough to start authorities thinking about time outdoors as a public health strategy."
Morgan says a prevention strategy is needed because severe myopia increases the risk of retinal detachment, which can lead to blindness.
He says Singapore faces the serious public health threat of having as much as 10% of its population developing a serious retinal problem later in life.
