What is a Hot Flash?
Hot flashes are characterized by a sudden feeling of warmth in the upper body, intense heat, sweating, and reddened skin during these episodes are common symptoms during menopause.
These flashes can start during perimenopause, continue through menopause and postmenopause, and even persist indefinitely. Hot flashes result from an imbalance in the hormones that regulate body temperature. They can bring on perspiration, also known as night sweats.
Thankfully, there are treatments to relieve these symptoms that can involve medications, non-hormonal therapies, or life alterations.

What Causes Hot Flashes?
Let's explore the various factors that lead to hot flashes, understanding their root causes and triggers:
Menopause
The most common cause of hot flashes is due to menopause, the natural cessation of menstruation that typically occurs between the ages of 45 and 55. It marks the end of a woman’s reproductive period and is a normal part of aging for women.

Sleepme Menopause Study Results
Sleepme was recently involved in a new Wake Forest University menopause study [2] which investigated the role between colder sleep and the worst symptoms of menopause: hot flashes and night sweats.
Additionally, hot flashes can be triggered by several other factors, including:
Stress & Anxiety
Stress and anxiety can significantly impact the body, often triggering physiological responses like hot flashes. When an individual is stressed or anxious, the body's natural reaction can disrupt its normal temperature regulation, leading to sudden warmth or sweating.
This reaction is due to the release of certain hormones during stressful situations, which can inadvertently trigger the same mechanisms that cause hot flashes. Understanding and managing stress through relaxation techniques or lifestyle changes is an effective way to help reduce the occurrence of these symptoms.
The Impact of Alcohol and Caffeine
Alcohol and caffeine are known to affect the body's temperature regulation, which can trigger hot flashes in some individuals. Alcohol, for instance, can cause the blood vessels to dilate, leading to an increased sensation of warmth.
Similarly, caffeine stimulates the nervous system and can disrupt hormonal balance, both of which can contribute to the onset of hot flashes. Being mindful of alcohol and caffeine consumption, especially in the evening hours, can help manage these sudden warmth episodes and contribute to overall better temperature regulation in the body.
The Role of Spicy Foods
For some, consuming spicy foods can act as a trigger. This is because spicy ingredients can stimulate the body's heat receptors, causing an increase in body temperature. When these heat receptors are activated, it can mimic the thermal sensations associated with hot flashes, including a sudden feeling of warmth and sweating.
This reaction can vary significantly among individuals; some may be more sensitive than others. Being aware of this potential trigger can help manage and reduce the occurrence of hot flashes at night.
Smoking
Smoking can be a significant contributor to hot flashes. The chemicals in cigarettes, particularly nicotine, affect the body's temperature control mechanisms. Nicotine can cause blood vessels to constrict and then suddenly dilate, leading to a rapid increase in skin temperature—a sensation similar to what occurs during a hot flash.
Bedroom Environment
Sleeping in a hotbed or bedroom can result in hot flashes and night sweats. If you are experiencing either one of them, a good way to begin recognizing your triggers would be to start a journal to help understand the occurrence and severity.
You'll be able to track how hot flashes vary more, including what you were doing, drinking, eating, wearing, or feeling when they occur. After several weeks, you may see a pattern that can help you to avoid specific triggers.

Avoid Triggers
When managing hot flashes at night, it's important to be aware of and gradually avoid certain triggers. These triggers can include substances like alcohol and caffeine, which are known to affect your body's temperature regulation. Certain foods can also induce heat sensations in the body, potentially triggering hot flashes.
Additionally, tobacco use has been linked to increased hot flash frequency. By being mindful of these triggers and reducing your exposure to them, you can help minimize the occurrence and severity of hot flashes. This approach allows you to better control these symptoms through lifestyle adjustments.
Exercise Regularly
Regular physical activity can help reduce the frequency and severity of hot flashes. In a recent study, women who regularly worked out five times a week for 45 minutes experienced a 60% reduction in the frequency of hot flashes. [3]
Practice Relaxation Techniques
Techniques such as deep breathing, meditation, and yoga may reduce the severity and instances of hot flashes.
At Sleepme, we offer a variety of mindfulness and wellness exercises to help you relax. Below are just a handful of exercises to help your body find and maintain relaxation more easily.
Eat a Healthy Diet:
Which is the menopause diet? A whole-food diet with plenty of fruits, vegetables, and whole grains may help reduce hot flashes. Popular food choices include green leafy vegetables, broccoli, carrots, apples, pineapples, proteins, fatty fish (salmon), nuts, and seeds.
Stay Hydrated
Staying hydrated by drinking plenty of water is key to managing your body's temperature and can be particularly beneficial. Water helps to cool the body internally, which can mitigate the intensity and frequency of hot flashes.
Adequate hydration also aids in overall bodily functions and can contribute to feeling more comfortable and less prone to sudden temperature spikes. It's important to integrate regular water intake throughout the day to maintain a consistent level of hydration, which can be crucial in helping to regulate body temperature during menopausal changes.
When to See Your Doctor
Hot flashes can be managed with lifestyle changes and over-the-counter remedies. However, it is a good idea to see a doctor if they disrupt your daily life, if you have other unexplained symptoms, or if you are experiencing symptoms and have not, to your knowledge, entered perimenopause yet.
The North American Menopause Society website provides a search feature for women in the United States or Canada who are looking for healthcare providers interested in helping them manage their health during and after menopause. This feature can help women manage their health through menopause and beyond. Get started here.
Final Thought
Maintaining a healthy lifestyle can lower the amount and intensity of hot flashes. Since no two women are alike, the methods used to treat hot flashes may vary. Also, it's important to understand that hot flashes may only last a few months, while others experience symptoms of menopause for several years or longer.
Remember, trying different treatment options may be beneficial if one isn't successful, and this uncomfortable experience will eventually end.

At What Age Do Hot Flashes Start?
The onset of perimenopause and its associated symptoms, like hot flashes, vary from person to person. Typically, most people begin experiencing perimenopause and potentially hot flashes in their late 40s to early 50s. However, it's important to remember that every individual's experience can differ, and these ages are general estimates rather than fixed rules. View Resource
What Does a Hot Flash Feel Like?
A sudden feeling of intense internal heat, excessive sweating, and flushing characterizes a hot flash. The skin, especially on the face, neck, and chest, becomes hot and red, and chills may follow due to the rapid loss of body heat. It can cause an increased heart rate (typically around 7-15 beats per minute) and anxiety in some individuals. The severity of hot flashes varies from person to person. View Resource
How Long Do Hot Flashes Usually Last?
They typically last for 1-5 minutes, though some occurrences may last for an hour. Hot flashes are a common symptom of menopause that usually lasts for about four years. You may experience them only during perimenopause or continue to have them after your period stops. Some people may even have them for the rest of their lives, but generally, they become less frequent or less intense over time. View Resource
Can Men Experience Hot Flashes?
Although hot flashes are more commonly associated with women during menopause, men can also experience them. Hot flashes in men usually occur due to a significant decrease in testosterone levels, especially in those who are undergoing androgen deprivation therapy for prostate cancer treatment. However, other factors like lifestyle, stress, and certain medical conditions can also contribute to hot flashes in men. View Resource
