Temperature has a significant impact on sleep, as the drop in our body temperature in the evening triggers a natural feeling of tiredness. The optimal room temperature for sleeping is 16-19 degrees, which supports a decrease in the body's core temperature and the achievement of deep sleep. A bedroom that is too warm or cold disrupts the quality of sleep, causing restlessness, arousal and shallow sleep.
The importance of temperature for a quality night's sleep
Temperature is one of the most important factors that affects the quality and duration of sleep . Our bodies follow a natural circadian rhythm where our core temperature begins to drop in the evening in preparation for rest. This drop in temperature sends a signal to the brain that it is time to sleep.
During sleep, our body temperature continues to drop, reaching its lowest point in the early hours of the morning. This process is essential for achieving deep, restorative sleep. When the ambient temperature supports this natural cooling, we sleep better and wake up more refreshed.
What is the best temperature for sleeping?
According to research, the optimal sleeping temperature is 16-19 degrees Celsius. This temperature range allows the body to cool naturally without having to use energy to produce heat. In a cool room, the body can fully relax, which promotes deep sleep.
Individual differences affect what temperature feels best. Women may need a slightly warmer room than men, and age can change temperature preferences. Children, on the other hand, often sleep best in a slightly warmer temperature, around 18-21 degrees.
How does a room that is too warm or cold disrupt sleep?
A bedroom that is too warm prevents the body from naturally cooling itself, leading to restlessness and shallow sleep. In a hot room, we sweat, toss and turn constantly, and wake up more often during the night. This especially disrupts the REM sleep stages, which are important for memory and learning.
A room that is too cold, on the other hand, causes muscle tension and shivering as the body tries to maintain a normal temperature. The cold can wake us up in the middle of our sleep, and we may feel stiff and tired in the morning. Extreme temperatures in either direction significantly reduce the quality of a night's sleep.
What kind of bedding supports the optimal sleeping temperature?
Choosing the right bedding is key to regulating your temperature . Natural materials like cotton and linen breathe well and wick moisture away from your skin. Technical fabrics can offer excellent temperature-regulating properties, especially if you sweat easily at night.
Seasonal duvet solutions help maintain a comfortable sleeping temperature all year round. In summer, a thin cotton duvet is enough, while in winter, a warmer down duvet keeps you warm without sweating. Sisustus1's high-quality bedding is designed to support optimal sleeping conditions, and you can view the products at our Helsinki showroom .
Practical tips for achieving the perfect sleeping temperature
Optimizing your bedroom temperature starts with adjusting the ventilation. Open a window a crack or use a fan to circulate the air. Using blackout curtains in the summer will prevent the sun from heating the room during the day.
Your choice of sleepwear has a significant impact on how warm or cold you feel at night. Lightweight, breathable materials are the best choice. Other helpful tips include:
- Taking a warm shower before bed, which helps lower your body temperature
- Removing electronic devices from the bedroom, as they produce heat
- Choosing mattress and pillow materials with temperature in mind
- Wearing wool socks on cold nights, which helps distribute body heat
Better sleep starts with the right temperature. By keeping your bedroom cool and choosing the right bedding, you create the optimal conditions for a quality night's sleep. Small changes to your sleeping environment can make a big difference in your sleep quality and your daily alertness.
