When temperatures climb, so can your chances of having hot flashes. Menopausal symptoms, including both hot flashes and night sweats, tend to show up most frequently in the height of summer — peaking around July — and are least common in the winter months.
“Hot flashes may be more frequent in the warmer weather due to the warmer environment increasing our body temperature,” says Pamela Miles, MD, a certified menopause practitioner and ob-gyn at the University of Oklahoma Health in Oklahoma City. In this stage of life, “even minor changes in temperature can trigger a response to sweat,” she says.
Environmental, physiological, and emotional factors play a role in summertime hot flashes, and identifying and understanding these triggers may help you reduce their frequency and intensity.
Common Triggers to Look Out For
No two people experience menopause in the exact same way, but hot flashes have a host of predictable triggers, many of which can be managed with lifestyle adjustments.
Hot Weather
It’s no huge surprise that when the air temperature soars, so does your internal thermostat. Excessive heat directly raises your core body temperature, nudging your temperature control system toward a cooling response that triggers a hot flash.When you feel one coming on, drink a glass of cold water and relax until it passes. Dehydration can make hot flashes worse, so it’s important to drink plenty of water and other healthy fluids.
Humidity
Humidity interferes with the body’s natural cooling process: sweating. When moisture levels in the air are high, the body’s ability to cool itself down is limited.
“Increased humidity doesn’t allow the sweat to evaporate as well,” says Dr. Miles.
To help keep your body dry, wear loose clothing made of breathable, natural fabrics. The same goes with bedding — synthetic materials can trap heat and moisture, keeping you clammy and uncomfortable.
Travel and Event Stress
Miles says that stress is its own trigger for hot flashes, and summer vacations — with crowded airports and long lines at tourist spots — can bring an array of hot flash-inducing challenges.
“Changes in schedules and the planning involved for a vacation, houseguests, or family reunions can add to our stress and, therefore, our hot flashes,” says Miles.
Stress activates the body’s cortisol response, which can heighten sensitivity to temperature changes. If you’re feeling revved up while you’re sitting in traffic or sidelined by a flight delay, try simple deep-breathing exercises to help calm you down. “Be prepared to be flexible, and things will be better,” says Miles.
Emotional stress can add on, too. Events like weddings, graduations, and summer parties often come with logistical and social demands that can make stress levels — and hot flashes — rise. Drink in moderation, find a graceful exit for conversations that stress you out, and look for a quiet corner to relax when you’re feeling overwhelmed.
Dietary and Beverage Choices
“Summer gatherings can involve special or spicy foods that can trigger hot flashes,” says Miles. Hot sauces, BBQ rubs, and chile-based dishes may contain capsaicin, which activates heat receptors in the body and can prompt sweating and flushing even in cooler conditions.What you drink during hot weather can also influence how your body regulates heat. Iced caffeinated or alcoholic drinks may feel cooling in the moment, but both caffeine and alcohol are linked to more severe vasomotor symptoms in some women. Red wine in particular is noted for making hot flashes more intense, in addition to triggering hot flashes.Iced herbal teas or a festive mocktail can help keep you hydrated while not upping the odds for hot flashes. If you’re looking to limit your caffeine intake, green tea contains less than coffee, and chicory root coffee is naturally caffeine-free.
Outdoor Exercise
Regularly engaging in physical activity outdoors may cause a temporary spike in hot flashes because exercising naturally raises your core body temperature.However, regular movement has many benefits for both overall wellness and menopausal symptoms, including helping to manage body weight, improve sleep quality, and reduce anxiety and depression.When the temperature is soaring, avoid exercising outside in the early afternoon, as that tends to be the hottest time of day. Drink water before, during, and after activity, and take frequent breaks in the shade to help avoid heat illness or other emergencies.
Track Your Triggers
“Tracking your triggers can help you moderate or avoid hot flashes,” says Miles. Tracking tools for hot flashes range from simple journals to dedicated menopause apps, like Balance and Health & Her, and wearable devices, like Peri or Oura Ring, which are designed to help identify patterns over time.
Menopause-focused apps and tracking journals allow users to log symptoms like hot flashes and night sweats alongside factors such as sleep, stress, diet, and alcohol intake, which can help you find your specific triggers. Wearable devices and sleep-tracking systems capture physiological data like body temperature changes and nighttime awakenings, which can help detect patterns that might otherwise go unnoticed.
Mental Health and Hot Flashes
It’s no secret that the menopausal transition is linked to a host of mental health issues, including depression, anxiety, and suicidal ideation. Hot flashes and anxiety combined can create an unwelcome loop: You may be more prone to having hot flashes if you have anxiety, but the experience of a hot flash can trigger further feelings of worry and overwhelm.“Hot flashes have definite links to depression and anxiety, and this is often related to sleep disruptions,” says Miles. Deep breathing, meditation, and cognitive behavior therapy are a good starting point for many people. But if you’re unable to manage your hot flashes, mental health, or sleep disruptions on your own, seek help.“You should consider discussing mental health treatment with your doctor, and treatment can be done for varying lengths of time.” Some options, like estrogen therapy, may treat multiple menopause symptoms at once, including improving your mood. Discuss your symptoms with your doctor to find what type of mental health or hot flash treatment might be the best fit for you.
The Takeaway
Hot flashes and night sweats often worsen during the summer because warmer temperatures, higher humidity, and seasonal stress can make the body more sensitive to temperature changes.
Small adjustments to daily routines — such as staying cool, managing stress, and paying attention to food and drink choices — may make menopausal symptoms more manageable.
Tracking symptoms over time can uncover triggers and guide conversations with your healthcare provider about treatment or additional support.
