Health Tip: Who's at Greater Risk for Heat-Related Illness
Heat-related illness occurs when the body can't cool itself during extremely hot and humid conditions.
According to the U.S. Centers for Disease Control and Prevention, certain people are at greater risk, including:
* Infants and young children up to 4 years of age.
* People aged 65 and older.
* People who are significantly overweight or obese.
* People who overexert themselves or don't drink enough fluids.
* People with high blood pressure, heart disease, and those who take certain medications for depression, insomnia or poor circulation.
Health Tip: Healthy Nails, Healthy Body
Healthy fingernails and toe nails are strong, colorless and smooth. Yellowing, brittleness, ridges, crumbling and white spots are all signs that nails may not be completely healthy.
The U.S. National Library of Medicine says nail abnormalities may indicate health issues elsewhere in the body. The agency offers this list of what nail problems could indicate:
* Many types of infection, including bacterial, viral, fungal or yeast.
* Abnormal levels of oxygen in the blood.
* Kidney disease, liver disease, thyroid disease or psoriasis.
* Malnutrition or a vitamin deficiency.
