In general, a person can safely stay in a car with the windows rolled up for about 10 minutes in temperatures up to 75 degrees Fahrenheit. As the temperature rises, the amount of time a person can safely stay in the car decreases. For example, at 90 degrees Fahrenheit, a person can only safely stay in the car for about 5 minutes.
The number of people in the car also affects how long a person can safely stay inside. The more people in the car, the less air there is for each person to breathe, and the faster the temperature inside the car will rise.
If the car is running, the air conditioning can help to keep the temperature inside the car comfortable. However, if the car is not running, the temperature inside the car can quickly rise, even with the windows rolled down.
It is important to note that children are more vulnerable to heatstroke than adults. A child can develop heatstroke in a matter of minutes, even if the temperature outside is not that high.
If you are ever in a situation where you are stuck in a car with the windows rolled up, it is important to stay calm and try to find a way to get out of the car as soon as possible. If you are unable to get out of the car, try to stay in a shaded area and drink plenty of fluids.
