Why Do I Get Cold After Running

When I first started running, I noticed that I often felt cold after my workouts despite working up a sweat. It’s a common experience that many runners can relate to. So, why do we get cold after running?

The Science Behind Post-Run Chills

After doing some research and speaking with a sports doctor, I learned that the cold sensation after running is a result of several factors. When we run, our bodies generate heat to keep us going. This heat is produced by the muscles and other internal processes. When we stop running, our bodies continue to produce heat for a while before gradually decreasing the heat production. This rapid cooling down process can leave us feeling chilly, especially if we’re sweating.

Sweating and Evaporation

Speaking of sweating, it plays a significant role in post-run chills. When we sweat during our workout, the sweat evaporates off our skin, which helps to cool us down during the exercise. However, once we stop running, the evaporation of sweat can contribute to our body temperature dropping, leading to that “post-run chill” feeling.

Hydration and Blood Flow

Furthermore, dehydration can also play a part in feeling cold after running. When we’re dehydrated, our blood volume decreases, which can affect our body’s ability to regulate temperature effectively. Additionally, during exercise, our blood flow is directed toward our working muscles to fuel them with oxygen and nutrients. After we stop running, this intense blood flow to the muscles decreases, which can also contribute to feeling cold.

What You Can Do

So, how can we combat post-run chills? Firstly, it’s essential to stay hydrated before, during, and after our runs. Ensuring that we have enough fluids in our system can help regulate our body temperature more effectively. Additionally, wearing proper clothing to keep warm post-run and gradually cooling down after our workouts can also aid in minimizing the chills.


In conclusion, feeling cold after running is a common occurrence due to our body’s cooling down process, sweat evaporation, and potential dehydration effects. By understanding the science behind it and taking proactive measures to stay warm and hydrated, we can better manage post-run chills and focus on recovering effectively after our runs.
