Have you ever noticed how different seasons or climates can affect the depth of your sleep? Indeed, changes in temperature, atmospheric pressure, humidity, and precipitation can all have an impact on sleep, so staying informed about the weather can help you achieve high-quality sleep.
The shortening of daylight affects the body's biochemical substances. In the autumn and winter seasons, the duration of daylight decreases, resulting in less exposure to light. This can lead to a deficiency in vitamin D and also impact the production of serotonin, a substance that regulates the sleep cycle.
In addition, low levels of vitamin D are associated with daytime sleepiness, and changes in the light-dark cycle can affect the release of melatonin, making people feel more easily fatigued than usual.
In winter, the incidence of seasonal affective disorder (SAD) increases, and it is related to decreased sleep efficiency and reduced slow-wave sleep.
Cool air can help you sleep better. Temperature plays an important role in initiating sleep and regulating circadian rhythms. Studies have shown that cool air in the surrounding environment helps people enter deep sleep more easily.
For optimal rest, the ideal room temperature is between 16°C and 21°C, with the specific value depending on personal preferences, clothing, and bedding. Due to the lower temperatures in winter, it is easier to achieve a sleep-friendly temperature indoors.
