And then there’s hormonal or endocrine issues, like thyroid or diabetes, that can make you all sweaty at night.

But did you know that some lifestyle choices you’re making could also be the cause? Things like spicy food, caffeine, and alcohol can cause your body to sweat it out in the night. Or it could be as simple as your bedroom’s temperature.

Whatever the reason, when you wake up drenched in sweat during the night, it’s more than just an annoyance; it’s your body signalling that something may be out of balance. Here’s a closer look at why this happens and what your body might be trying to tell you.

Understanding Night Sweats

Defining Night Sweats

Night sweats are episodes of excessive sweating that occur at night, which can significantly disrupt your sleep. Unlike simple overheating from too many blankets or a warm bedroom, true night sweats are severe hot flashes occurring at night that can soak through your sleepwear as well as your bedding.

Body Temperature Regulation

Sweating is a natural mechanism to regulate your body temperature. During the night, your body’s temperature set point drops, prompting your body to release heat through sweating.

Common Triggers and Medical Conditions

Common triggers of sleep disturbances

Night sweats can be more than just a nuisance; they might be signaling underlying health issues or lifestyle habits that need addressing. Here are some specific triggers and the medical conditions they may be connected to.

Menopause and Hormonal Changes

Menopause is a significant hormonal transition for women, typically occurring between the ages of 45 and 55. During this time, your body decreases the production of estrogen and progesterone, leading to various symptoms including hot flushes and night sweats. These are also common symptoms of perimenopause, which can last for years and begins anywhere from your mid-30s to your mid-50s.

Infections and Fever

Infections are a common cause of night sweats because they often come with a fever. Bacterial infections like pneumonia, strep throat, and urinary tract infections can all lead to waking up drenched to the bone. When your body’s fighting off an infection, it raises your temperature, sometimes causing chills and shivering. Once the infection is under control, your body cools down through sweating.”

Medications and Substances

Various medications, including antidepressants, and other drugs prescribed for medical conditions may cause night sweats as a side effect. Caffeine, alcohol, and drug use can also lead to sweating at night. If you have a thyroid condition, medication or the condition itself can lead to changes in your body’s temperature regulation. It’s important to review your medications with your healthcare provider if you’re experiencing night sweats.

Serious Health Issues

When you wake up drenched in sweat, your body might be sending you an urgent message. Night sweats could be indicators of underlying serious health issues that require your attention, like:


Various types of cancer, including lymphoma and leukemia, can present with night sweats as a symptom. It is a result of cancer cells affecting the body’s ability to regulate temperature.

Systemic Conditions

Besides cancer, systemic medical conditions like HIV could also lead to night sweats. The body fights the infection, and as part of that process, it may cause elevated body temperatures during the night.

Endocrine Disorders

 Conditions that affect your hormone levels, such as hyperthyroidism or diabetes, can cause your body to overheat, especially at night.

Neurological Disorders

Some neurological conditions can disrupt your body’s temperature regulation, leading to excessive sweating during sleep. This is less common but worth investigating if other symptoms are present.

Remember, if you are experiencing persistent night sweats, it’s important to consult your healthcare provider for a thorough evaluation. These sweats could be more than just an annoyance; they might be a sign of a significant health condition like heart disease or tuberculosis. And while less likely, it’s worth noting that recent illnesses such as COVID-19 have been associated with night sweats too. Your well-being is paramount, so take these signals seriously and seek medical advice.

Lifestyle Factors

common triggers that impact sleep

Night sweats can be perplexing, but often they’re your body’s way of indicating a reaction to certain lifestyle choices and the environment you sleep in. Key influences include your diet, exercise habits, and your bedroom setup.

Diet and Activity

Your eating and exercise habits significantly impact your body’s temperature regulation. Consuming spicy food can trigger temporary heating due to capsaicin, an active component that causes a sensation of heat. Meanwhile, both alcohol and caffeine can interfere with your sleep cycle and raise your body temperature, leading to night sweats. Pay attention to what you consume, especially closer to bedtime, to help manage your nighttime temperature.

Sleep Environment

The quality of your sleep can be greatly influenced by the environment you create in your bedroom. Factors such as bedding, mattress, pajamas, and blankets all contribute to your comfort. Opt for materials that are lightweight, breathable and moisture-wicking to help keep you cool.

The temperature of your room also plays a crucial role. The ideal temperature for sleep is around 65 degrees Fahrenheit, as it helps your body maintain a thermal neutral zone. If it’s too warm, your body may struggle to reach this state, which can lead to night sweats. Make sure your environment is conducive to a cool, comfortable sleep.

When to Seek Medical Advice

Persistent night sweats are often your body’s method of alerting you that something might be amiss. Paying attention to additional signs can help you decide when to consult with a healthcare provider.

Expectations from Healthcare Providers
