Hypothyroidism is a condition in which the thyroid gland fails to produce enough thyroid hormones, which are essential for maintaining the body’s metabolism. This condition affects millions of people worldwide, and its incidence is on the rise.
What is the Thyroid Gland?
The thyroid gland is a small butterfly-shaped gland located in the neck. It produces hormones that regulate the body’s metabolism, heart rate, body temperature, and energy level.
What Causes Hypothyroidism?
Hypothyroidism can be caused by a variety of factors, including:.
- Aging
- Autoimmune disorders
- Congenital disorders
- Certain medications
- Radiation therapy
- Thyroid surgery
Signs and Symptoms of Hypothyroidism
Some of the common signs and symptoms of hypothyroidism include:.
- Fatigue
- Weight gain
- Cold intolerance
- Constipation
- Dry skin
- Hair loss
- Joint pain
- Menstrual changes
- Depression
Double the Time, Double the Risk of Hypothyroidism
According to a recent research, people who spend more than 3 hours per day watching television have double the risk of developing hypothyroidism as compared to individuals who watch less than an hour.
The study was conducted on over 3,200 adults aged 40 years and older.
The researchers observed the association between TV viewing time and the risk of hypothyroidism over a period of five years.
They found that those who watched more than 3 hours of TV each day had a 1.6 times higher risk of developing hypothyroidism than those who watched for less than an hour.
This increased risk was independent of various other factors, such as age, sex, education, smoking, alcohol consumption, physical activity, and body mass index (BMI).
The link between TV Viewing Time and Hypothyroidism
Although the exact mechanism behind the link between TV viewing time and hypothyroidism is not yet clear, the researchers speculate that prolonged sitting and a sedentary lifestyle could have an impact on the metabolism and thyroid hormones.
Another possibility is that the blue light emitted by screens could disrupt the production of melatonin, which is a hormone that regulates the sleep-wake cycle, and in turn, affect the levels of thyroid hormones.
Other Risk Factors for Hypothyroidism
Apart from prolonged TV viewing time, there are several other risk factors for hypothyroidism, including:.
- Age – As we age, the risk of hypothyroidism increases
- Sex – Women are more likely to develop hypothyroidism than men
- Autoimmune disorders – These conditions can damage the thyroid gland and affect its ability to produce hormones
- Radiation therapy – Exposure to radiation can damage the thyroid gland
- Thyroid surgery – Removal of all or part of the thyroid gland can lead to hypothyroidism
- Certain medications – Some medications can interfere with thyroid hormones
Prevention and Treatment of Hypothyroidism
Hypothyroidism cannot be prevented, but it can be managed effectively with medication. The standard treatment for hypothyroidism is thyroid hormone replacement therapy, which involves taking daily doses of synthetic thyroid hormone.
In addition to medication, making certain lifestyle changes, such as eating a healthy diet, getting regular exercise, and avoiding smoking and excessive alcohol consumption, can help manage the symptoms of hypothyroidism and improve overall health.
Conclusion
Hypothyroidism is a common condition that can have a significant impact on a person’s health and well-being.
While there are several risk factors for this condition, including age, sex, and certain medical treatments, recent research suggests that prolonged TV viewing time could increase the risk of developing hypothyroidism. By making certain lifestyle changes and seeking appropriate medical treatment, individuals with hypothyroidism can manage their symptoms effectively and lead a healthy, fulfilling life.
