My cousin's biology teacher told her class that the water we shower in is not hot enough to actually kill bacteria but it promotes bacteria to grow through its warmth. He said it is best to take as cool a shower as one can stand. Is this true?
Is sleeping on our left side in any way harmful for the heart (or anything else)? Some people tell me we shouldn't do it and others tell me it's actually better than sleeping on our right side. What's the truth?
