Introduction
Most species have changed their physiology to adapt to environmental cues like temperature, light, and rainfall. Seasonal fluctuations in the reproductive, metabolic, and psychological systems may result from these physiologic changes. The main regulators of these systems are thyroid hormones.
The hypothalamus-pituitary-thyroid (HPT) axis carefully controls their levels. However, the generalizability of seasonal thyroid function fluctuations in various demographic groupings must be clarified. According to one study, TSH and peripheral thyroid hormone levels peaked in the winter and fell to their lowest point in the summer.
An endocrine gland located in the neck is called the thyroid. It generates hormones that impact the metabolism and operation of all nucleated red blood cells. The thyroid creates hormones that control how the body works. Thyroid diseases, however, are among the most prevalent endocrine illnesses in the world.
Symptoms of hyperthyroidism, or an overactive thyroid, can include:
Experiencing anxiousness, irritation, and anxiety.
-
Unable to fall asleep.
-
Weight loss.
-
Goitre, or an enlarged thyroid gland.
-
Tremors and muscular weakness.
-
Experiencing irregular menstrual cycles.
-
Feeling heat-sensitive.
-
Having visual issues or irritated eyes.
Hypothyroidism symptoms might include the following:
-
Having a fatigued feeling.
-
Weight gain.
-
Becoming forgetful.
-
Having heavy and frequent menstruation.
-
Dry hair.
-
The voice became hoarse.
-
Developing a sensitivity to cold temperatures.
What Is the TSH Level?
The hypothalamic-pituitary-thyroid (HPT) axis primarily controls serum thyroid hormone levels. The serum TSH level is the most sensitive biomarker for determining thyroid function because it is sensitive to even minute variations in serum thyroid hormone levels within the reference range. Therefore, doctors can identify subclinical hypothyroidism and hyperthyroidism by measuring serum TSH values in individuals with serum thyroid hormone levels within the reference range.
Serum thyroid hormone levels in healthy people show significant interindividual variation, leading to broad reference ranges. The intraindividual variability, however, falls within a significantly smaller range. This implies that each person may have a unique set point for the hypothalamic-pituitary-thyroid axis.
How Can the Environment Influence Thyroid Function?
External stimuli, such as light and temperature, can affect thyroid function. Most organisms have changed their physiology to adapt to environmental cues like temperature, light, and rainfall. Seasonal fluctuations in the reproductive, metabolic, and psychological systems might result from these physiologic changes. The most important regulators of these systems are thyroid hormones. The hypothalamus-pituitary-thyroid (HPT) axis closely controls their levels. It is widely believed that the semiannual seasonal pattern of thyrotropin (TSH) levels promotes seasonality in human physiology.
How Does Cold Weather Affect Thyroid Function?
Hypothyroidism patients may observe that their symptoms worsen in the winter. This occurs because the thyroid has to work harder to maintain optimal function when the temperature decreases. Since the thyroid plays a crucial role in metabolism and heat regulation, it can render people more vulnerable to seasonal temperature variations.
The body requires more thyroid hormone during cold weather, which can create or worsen hypothyroid symptoms. The thyroid stimulating hormone (TSH) level typically rises while free T4 and free T3 levels fall during the colder months. The patient's replacement thyroid hormone dosage may need to be increased. People may notice that their hypothyroid symptoms intensify when the temperature drops.
Following are the tips that help manage thyroid function in cold weather:
Assess the Status of The Hormones - Repeating this process every two to three months, or at least with each season change, is crucial. Our thyroid gland does not produce enough thyroid hormones to meet the body's increased needs during the colder months. During the colder months, doctors frequently slightly increase the dose.
Take a Sunbath - People stay inside more during the winter, exacerbating their depressive symptoms. Serotonin levels are raised, and Seasonal Affective Disorder (SAD) is beaten by spending time in the sun. Even 20 to 30 minutes in the sunlight daily helps fight weariness and sadness.
Control The Appetite - Coffee and hot chocolate use rises in the winter. Additionally, seasonal sadness heightens the desire for processed meals and foods heavy in carbohydrates, making it challenging for thyroid patients to control their weight. One must be extremely careful with their nutritional decisions. Although hot drinks are wonderful, individuals should consume only a few. Increase the intake of carbohydrates from healthy sources.
Eat Thermogenic Food - Increase the intake of foods that promote thermogenesis to keep warm throughout the chilly months. As they are digested, these nutrients produce heat in the body, which keeps them warm. Some foods promoting thermogenesis include peppers, avocados, saturated fats from meat and butter, and coconut oil. They could also aid in weight loss.
Exercise - A drop in temperature should not be used as an excuse to skip a workout. Daily exercise for 30 to 40 minutes is crucial for thyroid patients to maintain a healthy metabolism and manage their symptoms.
How Does Summer Weather Affect Thyroid Function?
The Individual could feel better in the summer when the chilly mood swings of wet spring days are no longer there. Patients should not experience the summertime overheating that hyperthyroid people do. They could be taking too much thyroid hormone if they feel hot. For an adjustment, visit a doctor.
Conclusion
The onset of a new season may be accompanied by rising temperatures, approaching snowstorms, or changing foliage. The change of seasons might cause a person with a thyroid condition, such as hypothyroidism, to experience a new set of symptoms or some respite from existing ones. They could feel better in the summer when the chilly mood swings of any wet spring days are alleviated.
However, a person with hyperthyroidism may feel too warm in the summer. Wintertime increases in TSH levels indicate that the thyroid is not producing enough hormones for the body. In the winter, even those without a history of thyroid issues may be diagnosed with subclinical hypothyroidism (slightly raised TSH). Skin dryness is also a result of hypothyroidism.
The winter's reduced humidity can dry out and irritate the skin. Take shorter showers with warm (not hot) water and mild soap to rehydrate the skin. To learn more about the condition, consult the doctor.
