would i feel warmer or cooler in a back t-shirt at night?
i know that i will feel hotter in a black t-shirt on a hot day since black is a good absorber of radiant heat, so if it's at night?
good absorbers are also good radiators. Why?
To determine if you would feel warmer or cooler in a black t-shirt at night, it's important to understand how different colors interact with radiant heat.
During the day, a black t-shirt absorbs more radiant heat from the sun, which can make you feel hotter compared to wearing a lighter-colored t-shirt. This is because black is a good absorber of light and heat energy. However, at night, when there is no direct sun exposure, the situation changes.
In the absence of sunlight, the color of your t-shirt doesn't play a significant role in absorbing radiant heat. Instead, other factors become more important, such as the ambient temperature, humidity, and your body's heat loss mechanisms.
Black t-shirts may still retain slightly more heat from your body due to their ability to radiate heat effectively. This property is often associated with good absorbers also being good radiators. When the surrounding temperature is lower than your body temperature, a black t-shirt could potentially facilitate heat loss through radiation, making you feel cooler. However, the difference in perceived warmth between a black and other colored t-shirt at night would likely be minimal.
To get a more accurate idea of whether you would feel warmer or cooler in a black t-shirt at night, it's essential to consider the ambient temperature, airflow, humidity, and your personal comfort preferences.
