Melatonin
Serotonin is a neurotransmitter which can be converted into melatonin, a natural hormone, in the pineal gland. Both of these hormones play a key role in sleep. Melatonin is produced at night and it plays a key role in adjusting your body clock.
During perimenopause, the ovaries stop producing as much estrogen and progesterone. This can have a knock-on effect on other hormones, such as adrenal and thyroid hormones. These hormones regulate cellular energy in the body. If they are imbalanced, a person may feel fatigued.
Most of the time fatigue can be traced to one or more lifestyle issues, such as poor sleep habits or lack of exercise. Fatigue can be caused by a medicine or linked to depression. Sometimes fatigue is a symptom of an illness that needs treatment.
When your period starts, your levels of oestrogen and progesterone are at their lowest. This is known to cause a dip in energy. If you also experience cramps, you might find that the first few days of your period are a time for relaxation rather than fast-paced activity.
Reasons for fatigue in females include high sleep debt, being out of sync with your circadian rhythm, your menstrual cycle and period, pregnancy, menopause, hormonal contraceptives, poor diet, lack of exercise, stress and anxiety, medication side effects, and medical conditions like thyroid issues or anemia.
Fatigue and Sleep Issues
Estrogen is intimately linked to serotonin, and serotonin makes melatonin. Melatonin is the primary sleep hormone. This means, if you've been sleeping less and feeling fatigued, you could have low estrogen.
A blood test is one of the most common ways to test hormone levels. This test can detect testosterone, estrogen, cortisol, and thyroid levels. You should order a test that's specific to your gender, as a women's hormone test will look for different levels of sex hormones than a men's test.
Mood swings are another effect of low estrogen. You may feel sad, anxious, or frustrated. Shifting hormone levels and night sweats may disrupt your sleep. This can cause fatigue, which may make mood swings worse.
These lower hormone levels cause a number of health issues throughout your body: Brain and nervous system – You experience a mix of physical and emotional symptoms like mood swings, memory loss, irritability, hot flashes, fatigue, night sweats, anxiety, and depression.
The most common cause of low estrogen is menopause. But too much exercise, disordered eating, or complications with your ovaries could also lead to lower levels. HRT may be an option for reducing symptoms, but you should talk to your doctor about the risks and benefits.
The most common causes of excessive sleepiness are sleep deprivation and disorders like sleep apnea and insomnia. Depression and other mental health conditions, certain medications, and medical conditions affecting the brain and body can cause daytime drowsiness as well.
Most likely, you're still tired after 8 hours of sleep because you don't know your sleep need, you're getting less sleep than you think, you've got sleep debt, or you're out of sync with your circadian rhythm.
Raspberries, blueberries, blackberries, and strawberries are all hormone balancing foods packed with great nutrients. Berries are rich sources of vitamin C, which regulates your progesterone levels, particularly during the luteal (PMS) phase of your cycle [1].
Here's how to balance hormones naturally: Eat an anti-inflammatory diet; consume omega-3s, adaptogen herbal supplements, mushrooms, probiotics and other supplements like vitamin D; get good sleep; exercise; and control stress.
Fatigue is one of the most common symptoms of a hormone imbalance. Excess progesterone can make you sleepy. And if your thyroid -- the butterfly-shaped gland in your neck -- makes too little thyroid hormone, it can sap your energy. A simple blood test called a thyroid panel can tell you if your levels are too low.
The two most likely reasons you're always so tired no matter how much sleep you get are you've got high sleep debt or you're not living in sync with your circadian rhythm. You may also feel sleepy if you're ill, pregnant, or you've got a medical condition like anemia or diabetes.
Mental laziness and lack of motivation can also be caused by one simple problem: not having enough exercise and nutrients in the body. One should consider eating healthy food high in protein, such as green, leafy vegetables, and fatty fish. Research also suggests eating berries and walnuts and drinking coffee or tea.
