The effects of emotions on the body can be unforeseen, but real. A study links depression with loss of vision. Here we tell you more details about this finding and we remind you how to take care of your sight to keep it healthy longer.
Emotions can affect the body and new research often appears offering new examples. Such is the case of a study carried out by specialists from the National Institutes of Health of the United States ( NIH , for its acronym in English), according to which the loss of vision could be related to depression .
It does not mean simply being sad. Remember that depression occurs when sadness, lack of encouragement, feeling of loneliness and negative thoughts last longer than normal and become stronger, can become very intense, so much so that you can stand. Other emotional symptoms that depression can cause are:
- Restlessness and anxiety.
- Extreme insecurity and difficulty in making decisions, even in the simplest matters of life.
- Irritability and / or sudden and extreme mood swings, going from euphoria to crying inexplicably.
- Problems to concentrate and short-term memory.
- Loss of interest in previously enjoyed activities (including sex).
- Low self-esteem and pessimism: feeling that you’re not good at all or that nothing good happens to you.
- Ideas have hurt, suicidal thoughts or attempted suicide .
But that is not all. Depression can also manifest itself with physical symptoms , such as:
- Difficulty sleeping or sleeping excessively.
- Fatigue and exhaustion during the day.
- Weight gain or, on the contrary, lack of appetite.
- Digestive problems.
- Recurring pains that do not heal easily with treatment ( headache , back pain or stomach pain, to name a few).
And now it could also affect vision.
What the researchers did to arrive at this conclusion was to analyze the data of more than 10 thousand adults over 20 years old, who had participated in the United States National Survey, the Health and Nutrition Examination ( US National Health and Nutrition). Nutrition Examination Survey ), between the years 2005 and 2008.
They found that 11 percent of people with vision loss had depression , while among those who had no vision problems, only 5 percent were depressed.
Anyway, these results – which are published in JAMA Ophthalmology – do not show that one condition causes the other, but there could be a relationship between them, which can help, for example, to think better about suggestions and care that should be recommended to people who have depression , so that they can also protect the health of their eyes.
Remember that as the years go by, as some lose their hearing and others lose their teeth, there are people who tend to lose vision . That is why it is important that you adopt certain care to keep it in good condition (and the younger you start, the better ). Among them:
- Know your family history related to vision, since some eye diseases can be inherited.
- Learn to recognize the signs of poor vision .
- Use glasses or sunglasses , as well as protection, if you are exposed to situations of risk, whether at work, during some household chores, or doing sports.
- Keep blood pressure, cholesterol and blood sugar under control.
- Eat foods rich in antioxidants, such as green leafy vegetables.
- Limit the amount of alcohol you consume (if you drink alcoholic beverages) and do not smoke.
- Exercise regularly, as they stimulate blood circulation and oxygenation, which are also necessary for your eyes.
- Try to sleep well , because while we sleep our eyes lubricate and can clean the irritants to which they are exposed during the day, such as dust and smoke.
Also, remember to do regular check-ups with an ophthalmologist (the doctor specializing in eye care) whether you have depression or not, because eye diseases do not always give symptoms, but if you detect them in time you can take the necessary care sooner and thus you will avoid complications.
