The larvae of chiggers do not burrow into a person's skin; they also do not suck a person's blood. Chigger larvae pierce a person's skin and inject the person with a salivary secretion that contains powerful digestive enzymes.
To stay healthy, you need to continually replenish your fluid supply. Experts recommend drinking approximately two quarts (64 ounces or about eight glasses) of water each day. Of course, if you live in an extremely hot or cold area â or if you exercise a lot â you may need to drink a gallon or more of water every day.
People who weigh more need more water; for instance, a 200-pound person needs a little over nine glasses per day to stay hydrated. Altitude also increases fluid needs, and experts recommend people at higher altitudes drink 3-4 liters of water per day.
