Energy is the backbone of life. All systems in your body need energy to function properly. How you produce and distribute energy is complex; thyroid hormone function has a major impact on all of your energy systems. However, not all fatigue or tiredness is due to thyroid malfunction. How do you tell the difference?
Thyroid hormone governs the basal metabolic rate, which is like the idling speed of a car engine. Even when you are sitting in a chair or sleeping your 100 trillion cells keep making energy. This type of energy production is the foundation for all other energy and hormonal systems. If it is not up to par, no other system in your body works as well as it should.
When you step on the gas pedal during the day, thyroid hormone is not what goes into action. Increased activity of any kind is controlled by adrenaline, muscle activity, increased calorie burning, and an increased speed at which your cells make energy. If you have a sluggish thyroid you may still be able to make yourself have the energy to do things based on adrenaline driven necessity. You may also notice that you have too much reliance on stimulants such as caffeine, sugar, or cigarettes.
A demanding day may deplete your muscles of fuel, and induce enough wear and tear so that natural tiredness follows. Such fatigue is normal and why we need to sleep. Even pushing it day after day and cutting sleep short may not be a thyroid problem. However, such a poor lifestyle does push your system, and you may eventually develop a thyroid problem as a result. Getting less than seven hours of sleep per night is asking for trouble.
Thyroid-related fatigue starts to show up when you cannot sustain energy long enough, especially when compared to a past level of fitness or ability. If the thyroid foundation is weak, sustaining energy output is difficult. You will notice you just don’t seem to have the energy to do the things you used to be able to do.
The menstrual cycle, pregnancy, exercise, stress, and physical demands are all examples of increased energy demands that require increased energy output. Thus, to a degree, PMS is almost always a thyroid problem. The increased energy demands of the menstrual cycle are simply too much, partly due to an underlying thyroid weakness. Pregnancy is always a major test of the thyroid, since the thyroid is called upon to do metabolic work for two bodies. This is why thyroid issues often flare up during or following pregnancy.
Thyroid hormone is synergistic with growth hormone in muscles. When these two work properly together, then muscles feel fit. Exercise conditions thyroid hormone to work properly to assist general energy production. A lack of exercise contributes to poor thyroid function. The more fit your muscles feel, the less likely thyroid-related fatigue will be an issue for you. If you have poor thyroid function you frequently feel like you don’t have …read more
