Whether you are a hot or cold sleeper, your body temperature plays a crucial role in the quality of your sleep. A cold sleeper is someone who feels cold easily and often wakes up shivering and craving more blankets. They require a warmer sleeping environment, such as a warmer sleeping bag or additional layers, to maintain a comfortable body temperature. On the other hand, a hot sleeper tends to sweat during sleep and may prefer a cooler environment. Understanding your sleep temperature preferences can help you choose the right bedding, clothing, and environmental conditions for a good night's rest.

Cold sleepers require more blankets
The quality of sleep is directly linked to body temperature and the ability to maintain a comfortable core temperature during the night. A cold sleeper is someone who feels cold easily and often wakes up feeling cold and craving more blankets. They require a warm sleeping bag or multiple blankets to feel warm and comfortable.
Cold sleepers tend to have a sharp drop in body temperature when they sleep, and they may wake up shivering. They may need to pile on the blankets or wear additional layers to bed, such as socks, gloves, hats, or thermals. Some cold sleepers also use hot water bottles, exercise, or eat certain foods before bed to help regulate their body temperature.
The definition of a cold sleeper is subjective and based on individual comfort levels. A person who is a cold sleeper in one context may not be in another. For example, a person who is a cold sleeper at home may not necessarily be a cold sleeper while camping due to the different gear and conditions.
Additionally, there are certain environmental factors that can affect body temperature during sleep. For example, the temperature of the room, the type of mattress or bedding, and sunlight exposure during the day can all impact how warm or cold a person feels while sleeping.
Overall, if you are a cold sleeper, it is important to take steps to stay warm and comfortable during the night. This may include using more blankets, choosing warmer bedding, or adjusting the temperature of your bedroom.

Body temperature and quality of sleep
A person's body temperature and the temperature of their sleep environment both influence the quality of their sleep. The ideal room temperature for sleep is generally considered to be between 60°F and 68°F (15.6°C and 20°C). However, individual preferences and factors such as age can cause variation, with older adults preferring a slightly higher range of 68°F to 77°F (20°C to 25°C).
A cool, but not cold, room can aid in falling and staying asleep. As bedtime approaches, the body's temperature begins to drop, facilitating sleep. Throughout the night, body temperature continues to decrease, reaching its lowest point in the early morning hours. Conversely, a rise in core temperature can disrupt sleep.
To optimise sleep, one can manipulate the sleep environment. For those who sleep hot, breathable sheets, mattresses with breathable components, and cooling technologies can help. Conversely, those who sleep cold may benefit from turning up the thermostat a few degrees or adding more bedding layers.
Additionally, certain foods can increase body temperature and contribute to overheating during sleep. These include processed and fatty foods, caffeinated drinks, spicy foods, alcoholic beverages, and garlic.
Regulating body temperature and the sleep environment is essential for maintaining sleep quality and overall health. Excessively high or low temperatures can disrupt sleep and have adverse effects on health, including obesity and quality of life. Additionally, sleep position may also play a role in thermoregulation during sleep.

Cold sleepers and camping
A "cold sleeper" is someone who feels cold easily and thus requires a warm sleeping bag or multiple blankets to keep them warm. They may be comfortable with cool temperatures when awake, but their body temperature drops sharply when they sleep. They may also wake up in the middle of the night feeling cold and looking for more blankets.
On the other hand, a "warm sleeper" is someone who stays warm easily while sleeping and may not need as many blankets or a highly-rated sleeping bag to keep warm. They may kick off all the blankets and sheets on the bed and still sweat.
If you are a cold sleeper and enjoy camping, there are a few things you can do to stay warm:
- Choose a sleeping bag with a temperature rating lower than the surrounding air temperature. You may need to experiment with different sleeping bags to find the one that works best for you.
- Keep your feet warm with thick socks and down booties.
- Wear a head covering, such as a hat or balaclava, especially when temperatures drop below freezing.
- Do some light exercise before bed to warm up your body.
- Keep chocolate or carbs by your side for a quick energy boost if you wake up feeling chilly.
- Consider adding a closed-cell foam pad to your sleeping setup for extra insulation.
- Start the night with a second quilt bunched around your feet, and pull it over you if you wake up feeling cold later.
Remember that everyone is different, and what works for one cold sleeper may not work for another. It is important to pay attention to your own comfort and adjust your camping gear and preparations accordingly.

Regulating body temperature
On the other hand, a "warm sleeper" refers to someone who stays warm easily while sleeping and may not require as many layers or a lower-rated sleeping bag. Warm sleepers might find themselves kicking off blankets or sheets throughout the night.
Regardless of whether you identify as a cold or warm sleeper, there are several strategies you can employ to regulate your body temperature and improve your sleep quality:
- Manipulate your bedroom temperature: Keeping your bedroom cool can help induce sleep. Many studies suggest that the ideal sleep temperature is between 60–67°F (15.5–19.4°C). While this may not always be feasible, especially in hot climates, even a slight decrease in temperature can make a difference. Blackout curtains or blinds can also help block sunlight and keep the room cooler during the day.
- Choose the right mattress and bedding: Your mattress and bedding can impact your sleep temperature. If you're a warm sleeper, opt for breathable mattresses and sheets that wick away body heat. Conversely, if you're a cold sleeper, consider materials that trap heat, such as flannel or fleece.
- Be mindful of your diet: Certain foods can increase your body temperature and contribute to night sweats. Avoiding processed and fatty foods, caffeinated drinks, excess sodium, spicy foods, alcoholic beverages, onions, garlic, and even ice cream before bed may help regulate your body temperature.
- Experiment with different strategies: Every individual is unique, and what works for one person may not work for another. It's important to experiment with different strategies to find what suits you best. This could include exercising before bed, eating a midnight snack, or using a hot water bottle.
By understanding whether you are a cold or warm sleeper and implementing appropriate strategies to regulate your body temperature, you can significantly improve your sleep quality and overall well-being.

Foods that affect body temperature
While the human body is designed to regulate its temperature, certain foods can influence it. Here are some foods that can help increase or decrease body temperature:
Foods that increase body temperature:
- High-protein foods like nuts, avocados, seeds, olives, salmon, and eggs: These foods take longer to digest than carbohydrates, and the body produces more heat while breaking down proteins.
- Complex carbohydrates and whole grains: These foods take more energy to break down, increasing body heat and providing a feeling of fullness for longer.
- Fatty foods: Fat moves slowly through the digestive system, requiring more energy to digest, which increases body temperature.
- Spicy foods: Eating spicy food can leave you feeling warm and flushed due to the thermic effect of food.
- Bananas: Rich in magnesium and B vitamins, bananas help the thyroid and adrenal glands regulate body temperature, especially in cold weather.
- Roasted vegetables: Roasted sweet potatoes, butternut squash, or cauliflower can warm you up in the short term while baking and during digestion.
Foods that decrease body temperature:
- Watermelon and other high-water content fruits: The high water content in these foods slows down digestion and takes less energy from the body, leading to a cooling sensation.
- Leafy greens: Most raw fruits and vegetables are 80-95% water, which is easy to digest and quickly passes through the digestive system, providing a cooling effect.
- Alcohol: While alcohol can cause flushing and a warming sensation due to vasodilation, it is a diuretic that can lead to dehydration, reducing the body's ability to cool down through sweating.
Additionally, staying hydrated with water is essential for regulating body temperature. Dehydration can cause a drop in core temperature, which may lead to hypothermia.
