Sodium deficiency or hyponatraemia refers to the low sodium concentration in the body of an individual. As other minerals, Sodium also plays essential roles in the human body. It is required for many of the functions of the body, including blood pressure management, fluid balance and the proper functioning of the nervous system. It may also sometimes lead to neurological impairments which affect walking and attention and could also result in bone fracture. Hyponatremia can be caused due to drinking too much of water, without enough replacement of sodium from the body. However, consuming too much of sodium can increase the volume of blood in the body, resulting in various health problems and can sometimes lead a person to coma.

The symptoms of sodium deficiency or hyponatraemia aren’t usually always specific. They can differ from person to person and depend on how rapid the fall in the sodium concentration of the body is. However, some of the common symptoms that are usually seen in the affected persons are as follows:

1. Gastrointestinal distress: One of the symptoms of hyponatraemia includes gastrointestinal distress. It may cause a decrease in the appetite of an individual and also result in nausea and vomiting. However, if a person suffering from sodium deficiency experiences vomiting, then their problem may continue to worsen.
2. Cognitive Impairment: Deficiency in sodium level can also result in abnormal mental status. Hyponatremia causes expanding of the tissue cells in the body. However, maximum tissues in the body can handle this change but the brain cannot. It is not capable of compensating for the increased size of the cells and as a result, the brain starts to dysfunction and causes a headache, confusion, lethargy and the problem of fatigue. With the worsening of the conditions, the person can experience hallucinations, decrease in consciousness and may also lead to coma.
3. Muscular Problems: Due to the drop in Sodium concentration, a person can experience various muscular problems including spasms or cramps. He/She may also suffer from fatigue. The weakness in the muscles and seizures are some of the additional symptoms of sodium deficiency.

The severity of these symptoms depends on the speed i.e., on how fast the fall in the blood salt level is. A gradual, low-level drop can be tolerated if it lasts for a few days or weeks, but the deficiency of sodium in the body can be fatal if not treated as early as possible. It may even lead to the death of a person. If you wish to discuss about any specific problem, you can consult a general physician.

Your eyes are an important part of your health. There are many things you can do to keep them healthy and make sure you are seeing your best. However, there are a number of myths regarding what you should do and what you shouldn't do when it comes to maintaining good eye health.

Here are 5 of those myths busted:

Myth #1: Reading in dim light and sitting too close to the tv hurts your eyes

Fact: Sitting too close to the tv, you may feel eye strain or get a headache from reading in the dark, but it will not weaken your eyes. It fatigues your eyes but does not harm your eye health in any way.

Myth #2: Eating carrots will improve your vision

Fact: Carrots are rich in vitamin a, a nutrient essential for good vision. But eating carrots will only provide a small amount of vitamin a. To get the optimum amount, you need to include other sources of vitamin a in your diet as well, some of which are milk, cheese, egg yolk and liver. Spinach is best for eye health. It has lutein and zeaxanthin, both of which can help prevent cataracts.

Myth #3: If you wear glasses or contacts for a continuous period, your eyes will weaken

Fact: Your eyes will not grow weaker by using corrective lenses. The prescription may change over time due to aging or absence of disease but it has nothing to do with your current prescription. Some children have correctable eye problems that do require glasses to improve the condition.

Myth #4: When you get something in your eye, rub it out

Fact: This is not true for everything that gets in your eyes. If any particle falls in your eyes dust it off. But if it is sand and small debris that gets in your eye, don't touch it. Use an eye wash for flushing it out. If an object gets stuck in your eye, don't remove it or rub your eye constantly. Visit a doctor at the earliest because some serious injuries may seem minor at first.

Myth #5: Dark sunglasses can protect your eyes from the sun

Fact: The color of sunglasses does not ensure eye protection. Look for sunglasses that block both uva and UVB rays. Exposure to the UV-rays of sunlight can have cumulative effects on your eyes. It increases your risk for cataracts, solar retinitis, and age-related vision loss. Even if your contacts have UV protection, wear sunglasses that block 100% of uva and UVB rays for full protection. If you wish to discuss about any specific problem, you can consult an ophthalmologist.
