Take It Easy and Get Plenty of Rest
Not getting enough sleep may be the reason you're sick in the first place. Proper rest is important for boosting the body's immune system and allowing it to fight damage. If you're sick, take things down a notch and rest — the last thing you want to do is overwork an already weakened immune system! Consider cutting back on exercise, calling in sick to work, or skipping a day from school. Let your mind and body relax while your body rejuvenates itself.
