Menopause & Perimenopause Care

Hot Flashes and Night Sweats: Why They Happen and What Helps

Vasomotor symptoms — hot flashes and night sweats — are the symptoms most people associate with menopause, and often the ones that disrupt sleep, work, and mood the most.

What is actually happening

Fluctuating and then declining estradiol narrows the range of body temperature your brain treats as comfortable. A small rise in core temperature triggers a full heat-release response: flushing, sweating, a racing heart, then chills as the body overcorrects.

Because the trigger is instability rather than a single low number, hot flashes often begin while cycles are still happening and while lab values still look ordinary.

What tends to make them louder

  • Interrupted or short sleep
  • Alcohol, especially in the evening
  • Rapid temperature swings and warm sleeping environments
  • Stress and anxiety, which share the same arousal pathways
  • Some medications, including certain antidepressants and thyroid over-replacement

Treatment options that get discussed in a visit

Systemic estradiol, with micronized progesterone when a uterus is present, remains the most effective treatment for moderate to severe vasomotor symptoms for people who are appropriate candidates.

Non-hormonal prescription options exist for people who prefer them or who have contraindications, and behavioral and sleep-focused strategies are used alongside either path.

Which option fits depends on your history, cardiovascular and breast health, time since your last period, and what bothers you most — not on a single protocol applied to everyone.

How care works here

Every visit is with Mallory Jones, MSN, APRN, FNP-C, CWHS. Visits are by video, and prescriptions go to the pharmacy you choose. Labs, when ordered, are billed separately by the lab.

Questions people ask

Can I have hot flashes and still be having periods?
Yes. Vasomotor symptoms commonly begin during perimenopause, while cycles are still occurring but becoming less predictable.
How long do hot flashes last?
The duration varies widely between individuals. For many people symptoms persist for several years, and for some they continue longer. This is part of what a visit is for — deciding what is worth treating and for how long.
Do I need labs before treatment?
Sometimes. Testing is used to rule out other contributors such as thyroid disease or anemia rather than to prove perimenopause. Labs, when ordered, are billed separately.
