How to Stop Overheating at Night (Without Gadgets or AC)

Tossing and turning in a pool of sweat? Overheating at night is a surprisingly common frustration, especially for those dealing with seasonal heat, stuffy bedrooms, or the hormonal changes of menopause. Before resorting to costly air conditioning or tech gadgets, consider natural alternatives that leverage materials and methods designed to work with your body’s thermoregulation.

This guide will help you discover how to stop overheating at night naturally with practical, sustainable solutions that improve airflow, prevent heat build-up, and keep you cool.

Why Heat Disrupts Your Sleep

Your body’s ability to regulate temperature is closely tied to its sleep stages. During the initial stages of rest, your core temperature needs to drop slightly to trigger deeper, restorative sleep. However, when your environment is too warm or your bedding traps heat, this natural cooling process gets disrupted.

Struggling to maintain a comfortable temperature can lead to shallow sleep, frequent wake-ups, and difficulty entering the all-important REM phase. If you often find yourself sleeping too hot, the key is to create a sleep environment that assists your body’s natural ability to cool itself.

As highlighted above, heat disrupts your sleep because your body relies on a slight drop in core temperature to initiate and maintain restful sleep. Here's how it works:

1. Thermoregulation and Sleep Stages: As you prepare for sleep, your body naturally cools down by about 1°C. This cooling signals your brain to transition into deeper sleep stages. If your environment is too warm, this process is hindered, making it harder to fall asleep or stay asleep.

2. Increased Wakefulness: Overheating can cause discomfort, leading to frequent wake-ups or shallow sleep. This prevents you from reaching the restorative deep and REM sleep stages.

3. Sweating and Dehydration: Excessive heat can trigger sweating, which may lead to dehydration and further disrupt your sleep cycle.

4. Hormonal Impact: Heat can interfere with the production of melatonin, the hormone that regulates sleep, making it harder for your body to relax and wind down.

In short, a cool environment is essential for quality sleep and avoiding overheating at night, as it supports your body's natural thermoregulation and ensures uninterrupted rest.

The Natural Materials That Help You Stay Cool While Sleeping

One of the simplest ways to combat overheating is by choosing temperature-regulating, natural cooling bedding. Unlike synthetics, which can trap heat and moisture, materials like wool and cotton allow for better airflow and wick away sweat.

Wool vs. Cotton for Cooling Sleep

While cotton bedding is a popular option, wool takes natural breathability and moisture-wicking to the next level. Wool fibres actively pull moisture away from the skin and help it evaporate, keeping you cool and dry. Wool duvets, such as those from Putnams, are lightweight, breathable, and perfect for hot sleepers seeking summer sleep comfort.

Though cotton sheets are better than synthetics, they lack the unique thermoregulating capabilities of wool, which insulates without overheating.

Incorporating Other Breathable Sleep Materials

For even better results, consider upgrading your pillow.

Overheating often starts at the head and neck, making it essential to use a pillow with breathable materials. Graphite latex pillows and Organic buckwheat hull pillows are excellent choices for hot sleepers. Latex provides bounce with superb airflow, while buckwheat’s natural hull filling moulds to your shape and allows air to circulate, keeping heat away.

The Role of Pillows and Posture in Body Temperature

When people think about how to stay cool while sleeping, their minds often jump to what’s on top of them, but what’s underneath is just as crucial. Pillows and posture both play an unappreciated role in reducing heat build-up during sleep.

Choosing the Best Pillow for Hot Sleepers

Selecting the right pillow can make a significant difference.

A breathable latex pillow cradles your head while promoting airflow, and a buckwheat pillow’s open structure prevents overheating. The key is to avoid dense, foam-filled pillows that trap heat. 

Putnams offers a range of cooling pillow options tailored to your needs.

Elevation and Airflow

Sleeping posture matters more than you might think.

Using a wedge pillow to elevate your upper body or legs can improve airflow around your body and prevent heat retention. This slight elevation is particularly effective for back sleepers who often feel heat accumulate on their backs. Wedge supports from Putnams, designed with both comfort and thermoregulation in mind, are ideal for this purpose.

Cooling Your Bed Without High-Tech Solutions

You don’t need gadgets to create a cooler sleeping environment. Here are some simple yet effective swaps that make a significant difference.

Upgrade Your Bed Linens

Switch out synthetic materials for natural cooling bedding.

Look for light-coloured, breathable fabrics like organic cotton or bamboo sheets for additional comfort. Pair these with a wool duvet for all-season temperature control.

Adjust Your Bed Frame

Heat rises, so consider sleeping lower to the ground during warmer months. If your bed frame is high, you might even try placing your mattress on the floor temporarily. This reduces exposure to warmer air.

Optimise Your Room’s Airflow

Improving airflow is essential for combating summer sleep discomfort. Open windows in the evening to introduce fresh air, or create cross-breezes by positioning a fan to circulate cooler air without blasting it directly on you.

Blackout curtains can also help by blocking sunlight that heats the room during the day.

Simple Swaps That Make a Big Difference

Small lifestyle changes can further enhance your efforts to stay cool at night naturally.

• Hydrate Wisely
  Staying well-hydrated during the day is critical, but try sipping cool water before bed to prep your body for better thermoregulation.

• Shower Smarter
  A lukewarm shower before bed temporarily lowers your core temperature and leaves you feeling refreshed. Avoid extremely cold showers, as they can shock your body into generating heat.

• Choose Lightweight Sleepwear
  Wear loose, breathable pyjamas or consider moisture-wicking fabrics that keep sweat off your skin. Avoid synthetic materials that cling and trap heat.

• Simplify Your Meals
  Opt for lighter meals during the evening hours. Avoid heavy, spicy foods that may raise your internal temperature. Fresh salads or hydrating foods like watermelon are excellent summer options.
