I feel a little silly asking this - but here it goes anyways...<br /><br />Some hotels have a heat lamp in the bathroom. A long time ago, my grandparents had one in their bathroom... <br /><br />I guess I just don't understand the point of it. What's it for? What's it do? Why is it on a timer? Why are they sometimes red and sometimes white?<br /><br />This has been a mystery to me for too long.. I need answers!!!
