Better System. Better Balance.

Better Health.

Systems biology uses algorithms to measure body system balance in a holistic “real-life” forecast. We measure six Systems key to fertility health.​

The core issue for women with Cold PFPs is they feel colder than most other people, and they also tend to ‘feel the cold’ more (and be on the tired side). Their lack of heat is often a reflection of slower or lower body processes (the metabolic rate) than average. Cold PFPs are the natural opposite of Hot PFPs, who have faster or higher fertility metabolism, and a temperature profile somewhere in the middle is the ideal.

Being mammals, we’re all relatively warm, but some of us are warmer than others, and differences in warmth can affect parts of the body or be general. Temperatures often vary around the body, especially across the lower back, and it’s worth feeling for temperature differences in your lower abdomen, middle and chest. Our temperature varies depending on:

  • Heat levels generated within cells
  • Blood circulation
  • Exposure to heat and cold
  • Sex and hormone levels
  • Diet
  • Exercise
  • Drugs
  • Our age
  • Times of day
  • Infections and inflammation

Because the lower abdomen is where our reproductive organs are, the temperature here is more important than the other parts of the body. Abnormal temperature patterns are the main issues restricting Hot and Cold PFPs’ fertility, and the PFPs can develop differently, which is useful to know when trying to raise fertility.

Variations of Cold

It’s easiest to explain these differences using the terms “Full” and “Empty”:

  • Full refers to an excess (from outside) that reduces temperatures; frostbite and a frozen shoulder from exposure to cold are examples
  • Empty refers to a lack of heat (always internal) that causes a relative excess of cold, and hypothyroidism is a classic example

“Full Cold”

Full Cold is relatively simple to explain, as something from the outside is chilling the body, so frostbite is the obvious example, but infections by cold viruses are another option. They make the body chilly and create stiffness, aching, and clear mucus, while other viruses (‘flu or meningitis) are more inflammatory and produce heat symptoms.

Full Cold can directly affect a woman’s fertility, and it’s the main reason some young, fit and healthy women struggle to conceive. We all know that a severe cold can affect how the body functions, as anyone who’s had a frozen shoulder or their hands have thawed out will know! Cold can get “lodged” in the womb and affect how it functions, usually after the abdomen has got chilled from exposure to cold air or water.

Cold has a contracting action, which tightens tissues and slows the flow of fluids, and it can be difficult to shift and recover from. Women with Full Cold affecting their womb often have stabbing, fixed period pains with a contracting/sharp feel. Women with this issue will know that warmth on the abdomen eases the pain, with the heat working by reducing the cold and encouraging blood flow. Because cold slows things down, it’s not uncommon for cycles to be long or irregular as well as painful.

“Empty Cold”

Empty Cold is more subtle, as this variation of coldness develops when the body isn’t warm enough. It’s usually a gradual thing, without an apparent cause, until a point arrives when the relative lack of warmth and vitality becomes noticeable, usually most obviously at the end of the day or when over-tired.

The Empty Cold variation affects many Cold PFP women and is often due to a low metabolic rate that burns too little energy. Temperature profoundly impacts how the body works and sets the pace for body processes. While the metabolism and hormone balance are closely linked, there are many possible causes of Empty Cold:

  1. Low thyroid hormone levels
  2. Low progesterone levels
  3. Low pituitary hormones
  4. Consuming too much cold food and drinks
  5. A constitutional tendency to being cold
  6. Lack of exercise and activity to raise metabolism

Cold restricts and reduces movement, which encourages less activity and warmth, so the best ways to raise the temperature balance of the body are:

  • Move more
  • Make specific diet changes
  • Warming herbal combinations
  • Self-help techniques

Cold PFP and Female Fertility

Women with Cold PFP who fertility chart will often see low basal body temperatures (BBT) across the month, and they’re more likely to experience:

  • Luteal Phase Defect
  • Endometriosis
  • PCOS
  • Implantation failure
  • Miscarriage
  • Low libido
  • Low thyroid levels
  • Urinary frequency
  • Low mood and drive
  • Lower backache
  • Loose stools

The focus for women with Cold PFPs should be on raising their temperature and increasing vitality to improve the health of their cycles and eggs. These are all possible with the right support and some determination!
