Stop sleeping with a fan on at night! Many of you still don’t know what could happen if you continue to sleep like that all night.

As we age, it becomes increasingly important to prioritize our sleep and make sure we get the rest we need to stay healthy and energized. Dr. Kelvas, a sleep expert, highlights the impact of room temperature on our ability to fall asleep and stay asleep throughout the night.Buy vitamin supplements and nutritional supplements

If the room is too hot or too cold, our bodies have a hard time regulating the hormones necessary for good sleep. This can lead to difficulty falling asleep and staying asleep. The ideal room temperature to promote healthy sleep is between 15.5°C (60°F) and 20°C (68°F), according to the Sleep Foundation.

Understanding the interplay between temperature and our bodies is crucial. Our bodies have a built-in thermoregulatory mechanism that allows us to maintain a healthy body temperature, regardless of the ambient temperature. Sweating and shivering are two main mechanisms our bodies use to cool down or generate heat. The dilation and constriction of blood vessels also play a role in regulating body temperature.

When it comes to sleep, temperature continues to have an impact. Throughout our evolution, temperature has served as a cue for sleep and wake times. When our body temperature drops, we enter slow-wave sleep, which is crucial for our overall well-being. Conversely, an environment that is too warm can negatively affect REM sleep and slow-wave sleep. Humidity also has an impact on sleep quality; higher humidity reduces REM sleep and slow-wave sleep.

Sleeping in a cold room offers several benefits. It helps release melatonin, the sleep hormone, and prevents the rise of cortisol, the stress hormone that can disrupt sleep. Falling asleep faster and spending more time in restorative sleep stages such as REM and slow-wave sleep are additional benefits of a cool room. Additionally, sleeping in a cold room can increase the activation of brown fat, which promotes weight management. It also improves insulin sensitivity, which reduces the risk of type 2 diabetes, and may help prevent Alzheimer’s.

If you don’t have access to a thermostat, you can still take steps to optimize your sleep environment. A warm bath or shower in the evening can help lower body temperature and prepare it for sleep. Studies have shown a positive correlation between water-based passive body heating and several sleep metrics, including sleep onset, total sleep time, and sleep efficiency.

Prioritizing your sleep and creating the right sleep environment with the optimal room temperature can have a significant impact on your overall health and well-being, so tonight, remember to turn down your thermostat and enjoy the benefits of a cool room for better sleep.
