Mattress and bedding materials
Mattress Materials
The type of mattress you choose can significantly impact how hot or cold you feel during sleep due to differences in heat retention and breathability. Here are some options to consider:
- Memory Foam Mattresses: Traditional memory foam mattresses tend to retain heat, making them a good choice for cold sleepers. However, they may not be ideal for hot sleepers as they can trap heat and lead to uncomfortable sweating.
- Latex Mattresses: Natural latex mattresses are breathable and responsive, providing a cool and healthy sleep environment. They are hypoallergenic and ideal for hot sleepers as they dissipate body heat and prevent night sweats.
- Hybrid Mattresses: Hybrid mattresses, such as the Brooklyn Bedding Aurora Luxe, combine different materials to promote breathability and airflow. They are a good choice for hot sleepers as they help draw heat away from the body.
- Innerspring Mattresses: Innerspring mattresses are another breathable option that promotes airflow, making them suitable for hot sleepers.
Bedding Materials
Choosing the right bedding materials can also help regulate your sleep temperature. Here are some tips:
- Breathable Bedding: Opt for breathable bedding made from natural materials like cotton, bamboo, or wool. These materials promote airflow and help keep you cool.
- Duvet and Blanket Thickness: Choose a duvet or blanket based on your sleeping preferences. If you are a hot sleeper, go for a lighter-weight blanket. If you are a cold sleeper, consider a higher tog duvet, such as a natural feather and down option.
- Layering Bedding: Using multiple layers of bedding allows you to adjust your temperature easily. For example, you can use a thicker top cover with a lighter blanket underneath so you can remove the top layer if you get too warm.
- Temperature-Balancing Fabrics: Consider using temperature-balancing fabrics, such as wool or bamboo, for your mattress covers and sheets. These fabrics can help regulate your sleep temperature, keeping you comfortable throughout the night.
By selecting the right mattress and bedding materials, you can create a sleep environment that supports deeper and more restful sleep, ensuring you wake up feeling refreshed and energised.

Health conditions
The ideal room temperature for sleeping is generally considered to be anywhere from 60°F to 68°F (15.6°C to 20°C). However, the ideal temperature may vary from person to person, and factors such as bedding, clothing, and individual preferences also play a role in determining the optimal temperature for sleep.
Feeling too hot or cold at night may be related to certain health conditions. For example, underlying health issues such as anemia, hypothyroidism, or Raynaud's disease can contribute to feeling cold at night. On the other hand, menopause, hypoglycemia, and hormone disorders can lead to night sweats and a feeling of overheating.
Additionally, certain medications can also impact your body temperature during sleep. If you find that adjusting your room temperature and pre-bedtime habits do not help, it is recommended to consult a doctor to rule out any underlying medical conditions.
Sleep disorders, such as narcolepsy, sleep apnea, and sleepwalking, can also be considered health conditions that impact sleep. These conditions may cause individuals to fall asleep suddenly or experience disrupted sleep patterns, which can affect their overall sleep quality and duration.
Furthermore, disturbed nocturnal sleep can have adverse effects on daytime activities and overall health. It has been linked to various issues such as obesity, a decrease in quality of life, and even mortality. Therefore, maintaining a comfortable thermal sleep environment is crucial not only for sleep maintenance but also for overall health and well-being.

Room temperature
The ideal room temperature for sleeping is a topic that has been widely studied. According to experts, the optimal room temperature for sleeping is between 60°F and 68°F (15.6°C to 20°C). Most doctors recommend keeping the thermostat set between 65°F and 68°F (18.3°C to 20°C) for the most comfortable sleep.
However, it's important to note that everyone is different, and this temperature range may not work for everyone. Some people may prefer a slightly warmer or cooler room to sleep in. Additionally, infants and older adults may need a slightly warmer room temperature to sleep comfortably.
A cool room, generally, makes it easier to fall asleep and stay asleep. This is because your body's core temperature naturally decreases as you sleep, so a cool room complements this process. If your bedroom temperature is too high, it can disrupt your REM sleep and cause restlessness.
To ensure your room stays within the ideal temperature range, there are a few things you can do. Firstly, you can set your thermostat to drop during your sleeping hours, so the temperature is optimal during the night. Using blackout curtains or blinds during the day can also help keep the room cool by blocking out sunlight. If the temperature rises or falls outside of the ideal range, you can open windows or use air conditioning or fans to cool the room down or turn on the heat to warm it up.
The right bedding and mattress can also help regulate your sleeping temperature. If you tend to sleep hot, breathable fabrics such as cotton, linen, and flannel are good choices. Using a lightweight blanket or duvet can also help prevent overheating. On the other hand, if you're a cold sleeper, thicker, insulated covers made from wool, down feathers, silk, or cashmere fleece can help retain warmth. Electric blankets and heated mattress pads are also effective ways to stay warm.

Clothing
On the other hand, if you are a cold sleeper, you might want to opt for warmer clothing. Layering is a useful strategy for cold sleepers. Consider wearing long-sleeved shirts, flannels, or silk pyjamas. These fabrics help to retain heat. Wearing socks to bed can be particularly effective in keeping you warm, as we lose a lot of body heat through our feet. If you tend to feel chilly, you may also want to invest in a fluffy down comforter or extra blankets to add warmth.
It is important to note that the ideal sleep temperature varies from person to person. Generally, a room temperature between 60°F and 68°F (15.6°C and 20°C) is recommended for a comfortable sleep. However, older adults may prefer slightly warmer temperatures, ranging from 68°F to 77°F (20°C to 25°C). Additionally, infants should be dressed appropriately and may require a slightly warmer environment, but it is crucial to avoid overheating to reduce the risk of sudden infant death syndrome (SIDS).
By adjusting your clothing and bedding, you can create an optimal sleep environment that suits your temperature preferences. This can include choosing breathable mattresses and bedding for hot sleepers or insulated covers and thicker mattresses for cold sleepers. Ultimately, finding the right balance between clothing, bedding, and room temperature will help you achieve a restful night's sleep.
