About Hot and Cold Flashes

Hot flashes can be defined as feelings of sudden, intense heat, usually accompanied by an increased heart rate; flushing of the face and upper body; sweating; nausea; dizziness; anxiety; and more symptoms.

On the other side of the spectrum are cold flashes, which can occur after a hot flash when the body is cooling down or independent of a hot flash episode, depending on the woman. Cold flashes are characterized by chills, cold feet, and shivering.

Causes of Hot and Cold Flashes

Hot flashes and cold chills are caused by decreased hormone levels, specifically of estrogen.

This hormonal imbalance negatively impacts the hypothalamus, the brain's internal thermostat, causing it to become more sensitive to body temperature changes, thus triggering hot and cold flashes during menopause as means to cope with these changes. 

Causes of hot and cold flashes unrelated to menopause include:

  • Poor blood circulation
  • Thyroid problems
  • Medications (hormonal therapies, cancer drugs)
  • The flu or a bad common cold (with or without fever)

How to Manage Hot and Cold Flashes

There are several ways to manage hot flashes and cold flashes. Certain lifestyle choices can alleviate or help both symptoms, including:

  • Regular exercise, such as a brisk walk or short bicycle ride, has been shown to decrease the frequency of menopausal symptoms, such as hot flashes and cold chills.
  • Wholesome habits that include addiction control, proper hydration, and frequent stress relief can prevent the body from over or under heating.
  • A nutritious diet filled with phytoestrogenic foods can also encourage healthy estrogen levels in the body. Examples include soybeans, tofu, sesame seeds, and flaxseed, among other nuts and seeds.

If the hot flashes and cold chills - as well as other menopause symptoms - are disrupting everyday life, it is best to talk to a medical practitioner to develop a comprehensive treatment plan.
