Hot Flushes and Night Sweats After Menopause: Why They Happen

Hot flushes and night sweats are among the most common and recognisable symptoms of menopause. Many women expect menopause to simply mean the end of menstrual cycles, but the transition can involve a number of physical changes that affect daily comfort and sleep.

For some women, hot flushes occur occasionally. For others, they can happen many times a day or interrupt sleep through repeated night sweats.

Understanding why these symptoms occur helps explain why a whole-body approach to menopause care can be beneficial.

Why Do Hot Flushes Happen During Menopause?

Hot flushes occur because menopause affects the body’s temperature regulation system.

As oestrogen levels decline, the brain’s temperature control centre in the hypothalamus becomes more sensitive to small changes in body temperature. This can trigger sudden signals that cause:

• dilation of blood vessels

• increased skin temperature

• sweating

• rapid cooling afterwards

This process creates the familiar experience of a sudden wave of heat followed by perspiration or chills.

Research suggests that around 70–80% of women experience hot flushes during menopause (North American Menopause Society).

Why Night Sweats Often Disrupt Sleep

Night sweats are essentially hot flushes that occur during sleep.

When they happen repeatedly, they can cause:

• frequent waking

• difficulty returning to sleep

• morning fatigue

• reduced concentration during the day

Sleep disruption is one reason many women feel more exhausted during menopause.

Why Stress Can Make Hot Flushes Worse

Another important factor is the nervous system.

Studies have shown that hot flushes are influenced not only by hormones but also by the body’s stress response system.

When stress levels remain high, the nervous system becomes more reactive. This heightened sensitivity can make hot flushes more frequent or intense.

This helps explain why therapies that calm the nervous system can play a helpful role in menopause care.

Supporting the Body During Menopause

Menopause is a natural stage of life, but many women find that symptoms improve when the body is supported through:

• stress reduction

• improved sleep habits

• balanced nutrition

• physical activity

• supportive therapeutic care

Research increasingly supports the role of lifestyle and integrative approaches in improving menopause quality of life.

How Holistic Therapies May Help

Holistic therapies aim to support the body as a whole rather than focusing on a single symptom.

Some approaches commonly used during menopause include:

• therapeutic massage
• stress-reduction practices
• herbal medicine
• relaxation therapies
• lifestyle guidance

Massage therapies, for example, can help calm the nervous system and improve circulation, both of which may support overall wellbeing during menopause.

At Ayusha Ayurveda clinics in Newcastle and Bondi, therapies such as warm oil massage, marma therapy and nervous-system calming treatments are often chosen by women seeking supportive care during menopause.

These therapies are not intended to replace medical care but can complement broader menopause management.

When to Seek Medical Advice

Although hot flushes are common during menopause, women should always discuss persistent or severe symptoms with their healthcare provider.

Medical professionals can help determine whether symptoms are related to menopause or another health condition and recommend appropriate treatment options.
