Bio-Identical Hormone Replacement Therapy (BHRT) Hormones has gained popularity in recent years. Individuals are gradually realizing the immense impact that hormonal imbalances have on their overall well-being. Hormones play an essential role in our body. They regulate and control numerous bodily functions ranging from metabolism, sleep patterns, mood swings, sexual development, and reproduction. Hormonal imbalances can lead to several health problems such as fatigue, weight gain, low libido, mood disorders, and infertility. This week on the blog we will go in-depth about bio-identical hormone replacement therapy and how it can help unlock your potential for a healthier, longer life.


Hormones are chemicals produced by the endocrine glands that help regulate and control various bodily functions. They act as messengers, carrying information to different organs and tissues, ensuring they function correctly. Some of the essential hormones in our body include estrogen, progesterone, testosterone, thyroid hormone, cortisol, and insulin. Each hormone plays a crucial role in maintaining our health and well-being.


Hormones can be divided into three categories- androgens, estrogens, and progestogens. Androgens are primarily produced in the male testes and female ovaries. They play an essential role in male characteristics such as muscle mass, facial hair growth, and sex drive. Estrogens are mainly responsible for female reproductive health, but they also play a role in male sexual function. Progestogens are mostly produced by the ovaries and play a crucial part in regulating the menstrual cycle, maintaining pregnancy, and preparing the body for childbirth.


Hormones are produced in response to signals from the brain. The hypothalamus and pituitary gland, located in the brain, are responsible for sending these signals to the endocrine glands. Once released into the bloodstream, hormones travel throughout the body and attach themselves to specific receptors on organs or tissues, triggering a particular response.


Testosterone is a vital hormone in both men and women. It plays a crucial role in maintaining bone density, muscle mass, sex drive, mood, and energy levels. As we age, testosterone production decreases in both sexes. However, for women, this decrease occurs more rapidly during menopause when their estrogen levels also decrease. Low testosterone levels can lead to several health problems, such as osteoporosis, low libido, depression, fatigue, and loss of muscle mass.


Estrogen is the primary hormone responsible for female reproductive health. It helps regulate the menstrual cycle, maintain bone density, and promote healthy skin and hair. During menopause, estrogen production decreases significantly, leading to several uncomfortable symptoms such as hot flashes, night sweats, mood swings, and vaginal dryness.


Progesterone is crucial during pregnancy as it helps maintain the uterine lining for a healthy pregnancy. It also plays a role in maintaining bone density and regulating the menstrual cycle. During menopause, progesterone production decreases along with estrogen levels, leading to irregular periods and other symptoms.


Cortisol is the primary stress hormone responsible for regulating our body’s response to stress. It helps control blood sugar levels, metabolism, and immune system response. Chronic stress can lead to high cortisol levels, which can cause several health problems such as weight gain, sleep disturbances, anxiety, and depression.


DHEA is a precursor hormone that is converted into estrogen and testosterone in the body. It plays a crucial role in maintaining energy levels, promoting bone health, and supporting overall well-being.


Hormone imbalances can occur due to various reasons, such as aging, stress, poor diet, lack of exercise, environmental toxins, and certain medical conditions. These hormone imbalances can lead to several health problems and impact our overall well-being. Some common symptoms of hormonal imbalances include:

  • Fatigue
  • Weight gain or difficulty losing weight
  • Low libido
  • Mood swings and irritability
  • Sleep disturbances
  • Hot flashes or night sweats
  • Depression and anxiety
  • Infertility and irregular periods
  • and more!


Bio-identical hormone replacement therapy (BHRT) is a natural and personalized approach to balancing hormones in the body. BHRT uses plant-based hormones that are structurally identical to the hormones produced by our bodies, making them more easily absorbed and utilized. BHRT can be prescribed in various forms such as creams, pellets, pills, or injections and is customized to meet each individual’s specific needs.

BHRT can help alleviate symptoms of hormonal imbalances and restore balance to the body. By optimizing hormone levels, it can improve overall health and well-being, enhance energy levels, improve sleep quality, boost libido, and more.

Longevity Medicine and BHRT

Longevity medicine is an emerging field of medicine that focuses on preventing age-related diseases and promoting healthy aging. BHRT is considered a crucial part of longevity medicine as it helps balance hormones and promote overall health and vitality. By unlocking our potential for healthier hormone levels, we can enjoy a longer, healthier life.

Did you know that your body has its own internal clock? This “circadian rhythm” is responsible for regulating many different bodily functions, and can play a big role in your overall health. The start of Daylight-Saving Time this month is a good reminder to talk about circadian rhythm—the internal clock that governs our sleep-wake cycles. Most of us are familiar with the yearly ritual of setting our clocks ahead one hour, but do you know what circadian rhythm is and why it’s important? Understanding your own circadian rhythm and how to work with it can be an important part of maintaining good health. In this blog post, we’ll discuss what circadian rhythm is, how it works, and some ways that you can optimize your own rhythm to improve your health. Stay tuned!

Circadian rhythm is a natural, physiological process that regulates many different bodily functions.  It is controlled by a part of the brain called the suprachiasmatic nucleus (SCN), which responds to light and dark signals. These signals help to synchronize our body’s clocks with the 24-hour day-night cycle.

The circadian rhythm has a huge impact on our health. It can affect everything from our energy levels to our sleep quality. How rhythmic or not your circadian rhythm is can have wide-ranging effects on your health, including but not limited to the following:

Heart Health

Key functions of cardiovascular health work on a circadian rhythm[i]. When there is a disruption to our circadian rhythm, it can increase our risk for a whole host of cardiovascular problems. Heart attack, stroke, high blood pressure and irregular heartbeat have all been linked to circadian rhythm disruption. A 2019 research study found a higher risk of heart attack after both time changes, but particularly during daylight saving. It is believed that the sudden shift in light and dark can confuse the SCN and cause it to send mixed signals to the heart.


The body’s metabolic rate is also tied to its circadian rhythm. When the rhythm is disrupted, it can lead to weight gain, insulin resistance and other metabolic problems. People who have a more regular circadian rhythm are more likely to have a healthy weight, while those with disrupted rhythms are more prone to obesity and metabolic disorders. Metabolic homeostasis, the body’s ability to maintain a healthy weight, is regulated by the circadian rhythm.[ii]


The quality of our sleep is also closely tied to our circadian rhythm[iii]. The more regular and in sync our rhythm is, the better our sleep tends to be. People with disrupted circadian rhythms often suffer from insomnia, restless leg syndrome and other sleep problems. Poor sleep at the systems level can lead to a number of health problems, including obesity, diabetes and heart disease. There are specific disorders with known links to the central clock. These are known as circadian rhythm sleep disorders (CRSDs) and include:

Delayed Sleep Phase Disorder (DSPS):  People with this disorder have a hard time falling asleep and waking up at conventional times. They tend to go to bed late and wake up later than most people.

Advanced Sleep Phase Disorder (ASPD): People with this disorder fall asleep early and wake up very early, often before sunrise.

Irregular Sleep-Wake Syndrome (ISWS):  People with this disorder have no real pattern to their sleep and wake times.

Jet Lag:  This is a temporary disruption of the circadian rhythm that can occur when traveling across time zones.

Shift Work Disorder:  People who work at night or rotate shifts often have trouble adjusting their circadian rhythm to the new schedule.

Irregular Sleep-Wake Syndrome (ISWS):   People with this disorder have no real pattern to their sleep and wake times.


While the link between circadian rhythm and cancer is still being studied, there is some evidence that circadian rhythm disruption can increase the risk of cance[iv]r. One study showed that women who worked night shifts had a higher risk of breast cancer.[v] Another study found that people who slept fewer than six hours per night were more likely to develop colon cancer.[vi] More research is needed to determine the precise link between circadian rhythm and cancer, but the preliminary evidence is suggestive.

Blood-Sugar Regulation

The circadian rhythm also regulates blood sugar levels[vii]. When the rhythm is disrupted, it can lead to insulin resistance and type 2 diabetes. Studies have shown that people with regular circadian rhythms are less likely to develop type 2 diabetes, while those with disrupted rhythms are more prone to the disease.


Asthma is the result inflammation in the airways, which makes it difficult for you breathe.  In terms of circadian rhythm, asthma follows a “diurnal pattern” which refers to the regular daily fluctuations in symptoms. Asthma typically worsens during the day and is better at night. Research has shown that the disease path of asthma is closely linked to the circadian rhythm of certain inflammatory pathways.[viii]

Hormone Regulation

The circadian rhythm also regulates many hormones, including cortisol and melatonin. When the rhythm is disrupted, it can lead to hormone imbalance and a number of health problems. For example, people with disrupted circadian rhythms often have difficulty regulating their stress levels, which can lead to anxiety and depression. Melatonin is a hormone that helps regulate sleep-wake cycles. When the rhythm is disrupted, it can lead to problems with sleep and insomnia.


There are many ways to optimize your circadian rhythm and improve your health. Some tips include:

Daytime Light Exposure

Getting plenty of natural sunlight during the day is essential for keeping your circadian rhythm in check. Sunlight helps to synchronize the SCN and keep it aligned with the external environment. Make sure to get outside for at least a few minutes each day, even if it’s just to take a quick walk.

Blocking Light at Night

If you’re unable to get outside during the day, try to avoid exposure to artificial light at night. Blue light, in particular, can disrupt your circadian rhythm. Make sure to use blackout curtains or eye shades especially if you need to sleep in a room that has artificial light.

Staying on a Regular Schedule

Keeping a regular sleep schedule is one of the most important things you can do to optimize your circadian rhythm. Try to go to bed and wake up at the same time each day, even on weekends.

Eating a Healthy Diet

A healthy diet is also essential for keeping your circadian rhythm in check. Eat plenty of fruits and vegetables and make sure to get enough protein and healthy fats. Avoid eating processed foods and sugary snacks, which can disrupt your rhythm.

Exercising Regularly

There is an old saying that couldn’t be truer: “A tired dog is a good dog.”  Exercise is crucial for keeping your circadian rhythm in balance. Make sure to get at least 30 minutes of exercise each day, and try to do it at the same time each day whenever possible.

Managing Stress

Finally, managing stress is essential for keeping your circadian rhythm in check. When you’re stressed out, it can throw off your rhythm and lead to a host of health problems. Make sure to practice relaxation techniques such as yoga, meditation, and deep breathing exercises on a regular basis.

Caffeine Intake

Caffeine is a stimulant that can also disrupt your circadian rhythm. Try to avoid drinking caffeinated beverages late in the day, and try not to drink them at all if you’re struggling to get to bed.


The circadian rhythm is one of the most important patterns in your life and it has a significant impact on your health.  By understanding how this pattern works, you can make small changes to improve your well-being.
