How Biological Rhythms Affect Your Sleep

Biological Rhythms And Your Sleep

Your body is the result of millions of years of adaptation to the forces of nature. These natural forces are the movement of the planets, sun, moon and the stars. We witness these forces as the cycles of the ages, the seasons, tides, the days and the nights as well as the varied climates and weather patterns around the globe.

In actual fact there is a field of science called chronobiology. This is the field of biology that examines cyclic phenomenon in living organisms and their adaptation to solar and lunar related rhythms. “Chrono” pertains to time and “biology” pertains to the study or science of life. These cycles are known as biological rhythms. The most important biological rhythm is the circadian rhythm, a roughly 24 hour-cycle of the earth around the sun. Many aspects of not only human but all animal behaviour and physiology show circadian rhythmicity, including sleep, physical activity, alertness, hormone levels, body temperature, immune function, and digestive activity.

Some other important cycles are:

Perimenopause: The 4 Facts

1. You lose progesterone.

Perimenopause is known as the ‘second puberty’ due to the dramatic changes in reproductive hormones during this time. With the loss of regular cycles comes the loss of cyclic progesterone being created. Progesterone has many important functions, including assisting calm steady moods, nervous system reactions, stress response, immune system health, and the health of our skin and hair.

2. Oestrogen goes on a wild ride.

Oestrogen spikes are what contribute to heavy, flooding periods, insomnia, hot flushes and mood swings. Our body notices the lack of regular ovulation occurring and starts producing increased levels of Follicle Stimulating Hormone (FSH) in order to stimulate oestrogen production, in an attempt to ovulate. This means that oestrogen can spike to 3 times higher than ever before, and crash lower than ever before.

3. Depression and anxiety is common.

The exposure to fluctuating hormones during the perimenopausal period is associated with depression and depressive symptoms. Studies have shown that a shorter menopause transition may protect against perimenopausal depression.

4. You can alter this course!

Symptoms during this time can include hot flushes, insomnia, weight gain, vaginal dryness, reduced libido, and weakened pelvic floor muscles. Thankfully, there are so many things you can do to have a smoother, shorter, perimenopausal transition. A smooth perimenopause usually means a smooth menopause, as the body adapts to a lower levels of oestrogen with less fluctuations.


What Can You Do?

  • Supplement with magnesium. This can be incredibly beneficial for helping with hot flushes, night sweats, insomnia, and mood swings
  • For hot flushes, drink cool sage tea. I recommend 1 – 2 teaspoons of dried sage per cup, pour over boiling water, and drink once at room temperature. 3 – 4 cups daily is best
  • Black cohosh functions in a serotogenic manner by binding to oestrogen receptors, successfully decreasing vasomotor, psychiatric, and physical perimenopausal symptoms
  • Adaptogenic herbs are beneficial to normalise the physiological response in times of increased physical and emotional stress, as well as difficult periods of change. They help the body adapt to this time, and take some of the load off our adrenal glands
  • Consider decreasing or giving up alcohol at this time. It impairs oestrogen metabolism and detoxification, reduces our ability to deal with stress, may increase frequency of hot flushes, and depletes glutathione which negatively impacts our immune system
  • Natural progesterone can be very beneficial for some women
  • Say no more often
  • Exercise! 30 minutes of moderate exercise most days is enough to boost mood, manage stress levels, lose/maintain weight, decrease blood pressure, and reduce the risk of cardiovascular disease
  • Increase your phyto-oestrogen intake; try sesame seeds, linseeds, alfalfa, mung beans, oats, and fermented soy products such as tempeh and miso

Chronic Pain Case Study

Chronic Pain Case Study

In our past blog we defined chronic pain, what is actually happening in a body that is in pain, and discussed what tools we use here to assist recovery. Following on from this, we want to show you how all of that science translate to treatment in the real world – and how it may be of benefit to you!

Here is a case to illustrate the point.

Patient X came to see me in practice with chronic low back pain. He was 42 years old and said that he had trouble with his lower back on and off for 10 plus years. Tick number 1, this is a chronic pain case with the pain having been around for WAY MORE than 6 months.

As well as the back pain he also gets a burning/achey type numb pain down the right side of the body. Tick number 2, he finds it hard to localise where the pain is now and it appears to be vaguely described across a large area of the back.
