Summarize this article in one sentence.
Only you know how much of your time and yourself you can give to caregiving. That means it's important for you to set limits with yourself. You also need to express those limits with doctors, nurses, and other caregivers, so they're aware of when you will and when you won't be there. In a time when things seem out of control, you may neglect to focus on good eating habits. You may not eat much, or you may end up eating junk food. Both of those put a strain on you. Try to eat as healthy as you can, even if you have to order food in sometimes or rely on simple meals like salads. Remember to include lean proteins, whole grains, fruits, and veggies in your diet. Sleep can also be difficult when you're caring for a loved one. You may be too worried to sleep at times, or the task of caregiving may interrupt your sleep. However, try to get as much as you can, aiming for a regular 7 to 9 hours a day, even if you have to do it in smaller chunks. Not getting enough sleep can put a strain on your health, plus it will make you less effective as a caregiver. Exercising will also help you maintain your health while you're caring for a loved one. As an added bonus, it can reduce your stress level. However, it can be difficult when you are caregiving, so you'll need to find ways to work it into your schedule.  For instance, maybe you can take a short walk a couple of times a day. You could also do yoga at home or try jumping rope. You could also ask someone to come sit with your loved one while you take an hour or so to go exercise. That way, you get a much-needed break, plus the exercise you need. It can be easy to overlook signs of health problems in yourself when you’re caring for someone else. However, if you become sick, you won't be able to help your loved one, so it's best to stay on top of health problems. In fact, the best plan is to maintain your regular doctor's visits and dental checkups to make sure you're in good health.
Set limits. Eat well. Try to get enough sleep. Take time to exercise. Don't neglect signs of illness in yourself.
