1 INTRODUCTION Whether arising from sweat running over our skin or from grasping a cold wet glass of water, the perception of skin wetness, i.e. hygrosensing, is one of the most common sensory experiences in our lives (Filingeri & Havenith, 2018). Humans are very sensitive to skin wetness, and people can discriminate wetness levels differing by as little as of 0.04 mL of water (Ackerley et al., 2012); yet there is no evidence that our skin possesses a hygroreceptor (Filingeri & Havenith, 2015).

1 INTRODUCTION The ability to sense changes in body temperature and to consciously experience thermal sensations is a fundamental cutaneous sensory attribute that is necessary for optimal interactions with our surrounding thermal environment, as well as with the objects that contact our skin, such as clothing (Havenith, 2002; Song, 2011).

1 INTRODUCTION The breast is a complex part of the female anatomy that is highly deformable and, when unsupported, moves independently during dynamic movements, such as when running (Haake & Scurr, 2010; Nolte et al., 2016; Rajagopal et al., 2008). These dynamic breast movements can cause discomfort and represent a barrier to exercise for some women (Lawson & Lorentzen, 1990).
