What's the deal about avoiding blue lights when you are preparing for sleep?
Adequate sleep. What, exactly, is that? It’s certainly not the same for everyone. The amount of sleep you need depends on your age and on your own physiology. The average adult needs 7-8 hours of sleep, but some people (this is rare!!!) do fine with 5 or 6 hours and some need 9-10 (see our earlier blog on sleep). So, how do you know how much sleep you need? Do an experiment. For several days, go to bed when you are ready – you know when that is, and allow yourself to wake up naturally, whenever that is. If you feel rested, that is how much sleep you generally need.
