If it is a hot summer day and you’re asleep, does that affect REM, dreaming, the quality of your sleep? That’s speculative but could be the case. It may be that if people wear socks at night, for example, it’s harder to release that body temperature. And one of the places of the body where we’re best able to dissipate that heat may be the feet. We may feel hotter at night, but it’s because our core is redistributing heat from the core to the surface, to the periphery.

But it’s the temperature at the surface of the skin we feel. When I tell people that the body cools down at night, they say, ‘But I feel warm, hotter at night, not cooler.’ What happens is the heat produced in our core by our organs gets distributed to the surface of our skin, to then dissipate into the air, that’s how our core cools. Have you heard that feet have a role in regulating body temperature? Anything to that? Showers, not really, because if your body is not immersed in the water it doesn’t have nearly the same impact on the core. Is this why some people recommend a hot shower or bath before bed?Ī bath, yes. That’s part of it, but a bigger factor seems to be, you sit in that hot water, it raises your core temperature, then you get out and your core temperature rapidly drops, and it’s the cooling of the core that tends to make us feel sleepy. And people assume it’s because they’re very relaxed. This is why if you’ve ever sat in a hot tub or taken a hot bath, afterwards, people often feel sleepy when they get out. What happens is that after our core body temperature peaks, and then starts to drop, that cooling of the core tends to make us feel sleepy. Our core body temperature is lowest roughly two to three hours before our natural wake-up time in the morning, and then increases over the course of the day and peaks about two hours or so before we start to feel sleepy at night. What happens is there’s a regular daily rhythm, called the circadian rhythm, our core body temperature. And so, our body temperature, in particular our core body temperature, changes over the course of the day in predictable ways, and there are relationships between our core body temperature and how sleepy we feel at any point. The more of a discrepancy there is between our body temperature and room temperature, whether it’s too cold or too hot, it’s just harder to get comfortable and fall asleep.Īt a deeper level, there’s actually a pretty complex relationship between temperature regulation and sleep regulation. At a surface level, it’s a comfort issue. Why does temperature matter so much to our bodies when we’re trying to sleep?
