Can't Sleep From Excessive Night Sweats? 7 Lesser-Known Triggers You Should Know

Mar 01, 2024

Experiencing nightly sweats that soak your bedding is a common issue for many. Night sweats are a common annoyance that can wreak havoc on your sleep quality. While hormonal changes, infections, and certain medications are well-known causes, there are some lesser-known triggers you should be aware of. Read on to learn more about managing this disruptive symptom and finding an emergency room near you if needed.

To start, let’s define what constitutes night sweats. These are severe hot flashes occurring at night that soak your clothes and bedding enough to require changing them. It’s not just a minor sweat – night sweats can leave your sleep environment damp and make it nearly impossible to rest.

Why does this happen? When we sleep, body temperature regulation continues. If your body gets too warm, sweating helps release heat so you can stay asleep. Excessive sweating suggests your body is overwhelmed and working hard to cool down. The causes can range from menopause to serious medical conditions, making evaluation important. If you live in Harker Heights, TX, knowing the locations of emergency rooms in Harker Heights, TX, can help you seek prompt care as needed.

Lesser-Known Triggers of Night Sweats and How to Find Relief

Finding yourself frequently soaked in sweat during the night can interrupt your rest, leading to fatigue the following day. While hormones, infections, and medications are common culprits, other lesser-known factors can also trigger troublesome night sweats. Read on to learn about these underrecognized causes and get tips to improve your sleep.

Dietary Factors

Consuming spicy foods, caffeine, or alcohol too close to bedtime can raise your core body temperature and stimulate night sweating. Those with food sensitivities may also experience inflammatory responses that cause flushing and excessive perspiration at night. Avoiding triggers and eating lighter evening meals can provide relief.

Stress and Anxiety

High stress and anxiety levels activate your sympathetic nervous system, which controls your fight-or-flight response. This ramps up sweat production to cool the body down. Practicing relaxing bedtime routines like meditation, yoga, or reading can help manage stress-induced sweating episodes.

Sleep Environment

An overly warm sleep environment caused by weather, room temperature, or bedding can lead to night sweats. Use breathable cotton sheets, keep bedroom temperatures around 65°F, and wear moisture-wicking sleepwear to stay cool.

Undiagnosed Sleep Disorders

Conditions like sleep apnea, restless leg syndrome (RLS), and insomnia disrupt quality sleep and affect the autonomic nervous system. This can trigger night sweats. See your doctor for evaluation and possible treatment of any underlying sleep disorders.


When blood sugar drops too low overnight, it activates the sympathetic nervous system, causing sweating. Consuming a small bedtime snack with complex carbs or protein can help maintain normal glucose levels and prevent hypoglycemia-related night sweats.


Dehydration can have counterintuitive effects, hampering your body’s ability to cool itself through sweating. Be sure to drink enough fluids during the day to avoid becoming dehydrated. Consuming drinks rich in electrolytes can aid in restoring essential minerals.

Idiopathic Hyperhidrosis

This condition involves excessive, uncontrollable sweating without a clear trigger. If lifestyle modifications fall short in managing symptoms of idiopathic hyperhidrosis, consider consulting your doctor about the possibility of using prescription-strength antiperspirants or medications designed to minimize sweating.

Waking up frequently soaked in sweat shouldn’t just be dismissed as a minor annoyance. Evaluate your diet, sleep environment, stress levels, and any medical conditions to pinpoint what might be causing night sweats. Simple lifestyle changes like avoiding triggers, lowering bedroom temperature, and managing stress can go a long way toward achieving restful, sweat-free sleep. Talk to your doctor if self-care strategies aren’t providing adequate relief from disruptive night sweats.

Managing and Mitigating Night Sweats

If you regularly experience drenching night sweats that interrupt your sleep, it’s important to get to the root cause and find effective management strategies. Making certain lifestyle changes and optimizing your sleep environment can go a long way in reducing night sweats and their impact.

Start by evaluating your diet – avoid spicy foods, excess caffeine, alcohol, and potential food sensitivities in the evenings. Beverages and foods that can trigger inflammation, raise body temperature or stimulate sweating close to bedtime are common culprits.

Stress and anxiety must also be addressed through relaxation techniques, calming bedtime routines, exercise, and other lifestyle changes. Unmanaged stress can overactivate your sympathetic nervous system and lead to excessive perspiration.

Optimize your sleep environment by keeping bedroom temperatures around 65°F, using breathable cotton sheets, wearing moisture-wicking sleepwear, and using cooling pillows or mattresses. Creating the right conditions for sleep helps minimize sweating.

However, if your night sweats persist despite these efforts, it’s time to see a doctor. Excessive night sweating can be a red flag for conditions like idiopathic hyperhidrosis, hormonal disorders, sleep apnea, infections, and even cancers in rare cases. Diagnosing and properly treating any underlying condition is key.


Don’t ignore recurring night sweats that disrupt your rest. Be proactive in identifying triggers like diet, stress, sleep environment, and medical conditions that may be causing this annoying symptom. Often, minor changes can make a significant difference, but seeking medical guidance when necessary is crucial for ensuring restful sleep.
