Adequate fluids and rest are the basic treatment, but if you have a high fever or severe symptoms, please consult an ENT specialist.

Heat Waves and Heart Health

Extreme heat raises the risk of angina, heart attack, and cardiac arrest by increasing heart rate, promoting blood clotting, and placing added strain on the heart. Older adults age 65 and older, people with cardiovascular disease, and those with chronic conditions such as high blood pressure or diabetes need to be especially careful. On days when a heat wave warning is issued, please stay active indoors for safety.
