Sleep effects in Autumn & Winter - How the season & type of mattress affects us

We know that as the days get shorter and deeper into Autumn, we tend to sleep more. However, there are certain sleep benefits we experience when we leave the summer months behind, such as the return to standard time and cooler temperatures, which can help our bodies fall asleep more easily. Seasonality and duration of sleep A recent study in Japan confirmed an increase in participants' sleep duration of 19 minutes on average in the winter months compared to the summer months. However, the researchers observed a wide variation depending on age, gender and region of residence. Younger adults (ages 15-39) were more likely to experience difficulty maintaining sleep and excessive daytime sleepiness (EDS). Middle-aged people (ages 40–64) were more likely to experience difficulty falling asleep and waking in the morning, while the older population (ages 65–89) showed no such changes. The study results suggest that seasonality may affect sleep duration, but it may not affect everyone in the same way. "Respite" from DST We are soon approaching the end of the controversial Daylight Saving Time (DST). The rest of the time, from November to early March, is known as "standard time". Several studies have pointed to an increase in heart attacks and strokes in the first few days after DST starts in March. One study showed a 21% reduction in heart attacks and strokes on the Tuesday after fall, back to standard time.

The effects of temperature on sleep

Ambient temperature is one of the most important factors for the quality of our sleep. Alertness increases, while REM sleep decreases when our body is exposed to heat. As we prepare for sleep, the blood vessels in our skin dilate to cause heat loss - and exposure to high ambient temperatures can prevent the body from losing heat, increasing the risk of poor sleep. The thermal load of our body increases when heat combines with moisture. Greater exposure to cold primarily affects REM sleep during which the response to ambient temperature is blunted, so the ideal temperature for sleep is between 15 and 19 degrees Celsius.

A mattress suitable for the season

But how does stratum relate to seasonality? The answer lies… in the materials with which it is made. Quality layers made with 'breathable' materials will be the most effective at keeping you cool, no matter how hot you are covered up, while denser and more synthetic layers will be warmer.

• Spring mattresses : They allow for improved air flow between their coils, which means better breathing and a cooler night's sleep.
• Wool : Precious natural materials are often better than synthetics when it comes to regulating heat. Wool is particularly good for both its insulating properties and breathability, keeping you warm in winter and cool in summer.
• Latex Mattresses : The latex foam design allows for air circulation and breathability.
• Memory Fo am mattresses : Because it retains body heat, memory foam tends to make the mattress warm, while at the same time in combination with the right technologies, it also offers the corresponding coolness for a great feeling under the covers.

General tips for improving sleep during the fall and winter include:

• Exposure of the body to natural light, especially in the morning, or use of phototherapy
• Lowering the temperature of the thermostat before bed
• Take a warm bath two hours before bed
• Minimize alcohol consumption and smoking
• Choosing the right mattress!
