When to Call in Sick. You should ask for sick leave as soon as you know you need it. For example, you could notify your team several weeks in advance if you've had surgery scheduled. Or, in cases where you can feel the flu coming a day before it starts, you can call in sick as a precautionary measure.
Some people stop everything at the first signs of a serious cold, stomach bug, or other illness. That might seem extreme, but it is a good idea to call in sick and take a pause to rest and regroup before you become seriously ill, especially those who are working in-person.

Some People Have a Superhuman Strength: Only Needing 4 Hours of Sleep. These “short sleepers” don't necessarily do it by choice—they're genetically programmed to require less shut-eye. Short sleepers are people who do well with about half of the shut-eye that the rest of us require to function.
