When deciding between different pairs of pajamas to determine what works best for you, “look into different styles of the garment rather than just the fiber content,” Arya recommends. “They should check all their options, not just limit themselves.” Ultimately, it comes down to the personal preference of the sleeper to find out what suits them. If they often wear long pants and a t-shirt, it might be better to consider shorts and a tank top instead. Some hot sleepers might also find that no clothes keeps them the coolest in the evenings. “Sleeping without pajamas is one option to consider for anyone who finds themselves waking up due to being too warm,” Dr. Robbins says. There are a variety of reasons for why someone might be a hot sleeper, so it is important to test out styles based on your preferences and comfort levels, not anyone else's.
