Night Sweats Causes – Why You Might Have It

Waking up in the middle of the night because of sweat soaking your sheets can be a frustrating habit to deal with. It requires a change of clothes or a sheet change, and often leaves you bewildered about what is going on. While most people are unaware of it, night sweats are actually pretty common, and they can be caused by things like stress and poor lifestyle choices, or even hormonal and medical issues.

In this article, I will explore some of the reasons you might be dealing with night sweats, how it can impact your quality of sleep, and how your sleep environment can be improved by making some simple changes to your mattress. If you live in Saskatoon and are dealing with discomfort during rest, check out Restezzzy Mattresses. They provide a variety of mattress brands and sleep necessities to help you find what you need.

What Are Night Sweats?

Night sweats are episodes of excessive sweating during sleep that are not related to a hot bedroom or heavy blankets. Unlike normal sweating, night sweats usually occur even when the temperature is comfortable.

Night time perspiration is something everyone goes through. People experiencing it typically describe:

Waking up extremely sweaty
Damp pillows and sheets
Need to change clothes during the night
Feeling cold after sweating

While occasional sweating is normal, frequent night sweats are a sign that something deeper may be triggering your body’s temperature response.

Common Causes of Night Sweats

There’s no single reason behind night sweats — multiple factors can trigger them. Let’s look at the most common causes.

1. Stress & Anxiety

High stress levels can impact your body’s thermostat. When the nervous system becomes overactive, it increases adrenaline, body temperature, and sweating.

If you’ve been overthinking, worrying, or dealing with emotional pressure, night sweats may be a result.

2. Hormonal Changes

Hormones play a key role in body temperature regulation.

Night sweats are often linked to:

Menopause or perimenopause
Pregnancy
Thyroid imbalance
Puberty in teens

Women going through menopause report night sweats as one of the most common symptoms due to fluctuating estrogen levels.

3. Medications

Certain medicines list night sweats as a side effect, including:

Antidepressants (SSRIs)
Hormonal treatments
Diabetes medications
Pain relievers like aspirin and acetaminophen

If you’ve recently started a new medication, it might be worth discussing the symptoms with your doctor.

4. Infections

Some infections trigger fever along with night sweating. These include:

Flu or viral infections
Tuberculosis
COVID-19
Bacterial infections

If night sweats are accompanied by fever, cough, or fatigue, medical attention is recommended.

5. Sleep Environment & Bedding

Sometimes the cause isn’t internal — it’s external.

If your mattress, bedding, or sleepwear traps heat, your body may overheat at night. Common triggers include:

Memory foam without cooling technology
Heavy blankets or polyester comforters
Lack of airflow in the bedroom

Sleeping on a mattress that retains heat can keep your body temperature high throughout the night. That's why cooling mattresses and breathable bedding are becoming a popular solution.

How Your Mattress Affects Night Sweats

Even if medical or hormonal reasons exist, the wrong mattress can worsen night sweats.

Heat-trapping mattresses make things worse by:

Compressing around the body and restricting airflow
Holding onto body heat throughout the night
Causing discomfort that disrupts sleep cycles

Upgrading to a breathable, cooling mattress can drastically reduce heat buildup.
