We are all aware that aging can lead to certain health conditions, but no one has ever been really sure as to why this is. Scientists have worked for decades to try to explain why memory loss, slower reaction time, insomnia, and even depression develop in people as they grow older. The have investigated numerous factors such as obesity, high cholesterol, and heart disease.
Now, new research has revealed that a host of health problems may be caused by the aging of the eyes. Scientists discovered that the eyes get older, the circadian rhythms of the body become disturbed. This leads to many health issues.
Circadian rhythms are cyclical hormonal and physiological processes. They are the body’s internal clock. They tell you to get up in the morning and prepare you to meet the day. They tell you to go to sleep at night so that your body can rest and repair itself.
Your body’s circadian rhythms rely on light in order to function properly. People who work night shifts or disturb their circadian rhythms in some other way are at a higher risk for some health problems. Studies have found that these people are more likely to suffer from insomnia, heart disease, and cancer.
So how do your eyes fit into all of this? As we age, our eyes gradually begin to yellow, and our pupils become narrower. This affects the ability of the eye to absorb light. The absorption of light is what triggers the circadian rhythms.
Photoreceptive cells in the retina absorb sunlight and transmit messages to the part of the brain called the suprachiasmatic nucleus. This part of the brain governs the body’s internal clock. The suprachiasmatic nucleus initiates the release of the hormones melatonin in the evening and cortisol in the morning.
The role of the eyes in regulating the circadian rhythm did not become apparent until 2002. Scientist at this time discovered that the eyes had more photoreceptive cells than what was originally thought. A team discovered more of these cells in the inner retina, and these particular cells had more direct communication with the brain than others. This made them more important in regulating the circadian rhythms of the human body.
The easiest way to keep your circadian rhythms in order so that you do not experience health problems is to keep your eyes healthy. Regular eye exams are very important for this. The experts at East Village Vision in New York can provide you with expert care for your eyes. Keeping your eyes healthy will improve your overall health.
The eyes are essential for maintaining the health of the body. The amount of light that is detected by the eyes regulates the body’s circadian rhythms. When these rhythms are out of sync, a person will experience a host of health problems. Monitoring this becomes more and more important as we age because the eyes no longer detect light in the same way. Keep your eyes healthy and keep your body healthy.
