The hormonal peaks have been found to occur in the morning for progesterone, in the afternoon for FSH and LH, and during the night for oestradiol. These findings are unlikely to alter the time of day we order female reproductive hormone measurements.
Your hormone levels are naturally higher in the AM and lower in the evening. The drop in hormone levels at the end of the day actually signals the body that it needs to make “another batch” of hormones. The daily cycle of hormone production is described as a “circadian” rhythm – a 24 hour rhythm.
The diurnal cycle of estradiol exhibits an early morning peak and two, three or four ultradian harmonics throughout the 24-hour period [25]. During the menstrual phase, the peak in estradiol occurs later in the morning.
On Day 1 of the menstrual cycle, estrogen and progesterone levels are low. Low levels of estrogen and progesterone signal the pituitary gland to produce Follicle Stimulating Hormone (FSH).
This is about 1 week (5-7days) after ovulation occurs. In a 28-day cycle, this would-be days 19, 20, 21 or 22. This is the time in the menstrual cycle when progesterone should be at its peak for the month and when estrogen should be at the height of its luteal plateau.
Estrogen plays a role in the metabolism of serotonin and other neurotransmitters that affect our sleep-wake cycle. Estrogen also helps keep our body temperature low at night, and therefore more conducive to restful sleep.
A Fred Hutchinson Cancer Research Center study involving postmenopausal, overweight, and obese women who took 2,000 IUs of vitamin D daily for a year found that those whose vitamin D blood levels increased the most had the greatest reductions in blood estrogens, which are a known risk factor for breast cancer.
Melatonin is the hormone best known to affect sleep, being low during the daytime but rising once darkness sets in, leading to sleep. Melatonin is secreted by the pineal gland, to which the SCN projects via multiple synapses to drive the Circadian rhythm of production of this hormone.
The main cause here is stress and high cortisol levels. See, our circadian rhythm directs our cortisol, an awakening hormone, to rise around 3am, in preparation for the next morning. However, if you cortisol levels are already high, which is a consequence of stress, then it's likely you will wake up.
Body fat: Fat tissue (adipose tissue) secretes estrogen. Having a high percentage of body fat can lead to high estrogen levels. Stress: Your body produces the hormone cortisol in response to stress. Producing high amounts of cortisol in response to stress can deplete your body's ability to produce progesterone.
Fatigue
Unfortunately, estrogen dominance can cause fatigue. This symptom can occur whether or not you have insomnia. If you experience persistent tiredness or feel more drained of energy than usual, talk to your doctor about being tested for hormonal issues.
Generally speaking, levels of cortisol, your stress hormone, are higher in the morning to rouse you from sleep. Before the perimenopause, oestrogen helped to control this spike in cortisol.
What hormone keeps me awake at night? The main hormones that keep you awake at night at melatonin, cortisol, and insulin as mentioned in the previous section.
When estrogen is too high or too low you may get menstrual cycle changes, dry skin, hot flashes, trouble sleeping, night sweats, vaginal thinning and dryness, low sex drive, mood swings, weight gain, PMS, breast lumps, fatigue, depression and anxiety.
Vitamins and minerals that play a role in hormonal balance and managing estrogen deficiency symptoms include B complex, vitamin C, vitamin D, calcium, magnesium, and boron. Herbs and dietary supplements, including dong quai, black cohosh, astragalus, and DHEA, may have a more direct effect on low estrogen levels.
Estrogen can reduce menopausal symptoms like hot flashes, night sweats and vaginal dryness. If you have a uterus, you'll likely need to take progesterone along with the estrogen. Estrogen without progesterone increases the risk of uterine cancer.
It's very important to know which estrogen dominance foods to avoid. You should steer clear of red meats, processed food, refined carbs, and foods rich in saturated fats. These categories of foods have a negative impact on the body in general.
Hormone creation - magnesium actually makes your hormones progesterone, estrogen and testosterone, so if you're getting into perimenopause or are just off the Pill and your levels are low, it can be your best friend.
Estrogen imbalance: Vitamin D deficiency may lead to lowered estrogen levels, which can cause depression, hot flashes, mood swings and more.
