Here’s everything to know about how hot showers affect your body temperature.

Why Taking a Hot Shower Raises Your Body Temperature?

Heat is transferable, which means that an object with less heat will receive heat from a hotter object. The bigger the difference, the faster the heat transfer. In short, taking a hot shower can quickly raise your internal temperature because some of the heat from the hot water shower gets transferred to your body.

But how much heat is transferred will depend on a few factors. Sometimes, a hot shower can raise your temperature significantly to the point where you feel hot and even sweaty afterward. Other times, your temperature will rise by only a tiny amount. You might not even notice that there’s a difference unless you measure your temperature with a thermometer before and after your hot shower.

Why Do You Feel Feverish After a Hot Shower?

Feeling feverish or hot after a steamy shower is common when there’s high humidity in your bathroom. Humidity is higher on warm days unlike in the cold season when the air is dry. Or maybe your bathroom is particularly humid due to poor ventilation.

High humidity combined with the increased body temperature after a hot shower can leave you feeling slightly hot, sometimes sticky and sweaty too.

Feeling sweaty and icky post-shower is often enough to want to jump right back in the shower for round two. But there’s a simple tip that you can do to avoid feeling feverish after a hot shower – gradually lower the water temperature when you’re nearing the end of your shower.

If you’re taking a hot shower, consider lowering it from hot to warm, even if it’s just for the last 10 seconds of your shower. It only takes ten seconds or so for the body to adjust to a new temperature. You can also rinse your hair with cold water to remove any hot water from your scalp. These tips will help you stay fresh and eliminate that sweaty and sticky feeling after taking a hot shower.

Adequately Hot Showers: What Are the Benefits?
