NEWMARKET – The high temperatures of summer are here, prompting York Region EMS to remind residents to take extra precautions on hot days.
Heat exhaustion is the body's response to excessive loss of water and salt contained in sweat. Warning signs include heavy sweating, dizziness, headache, nausea or vomiting and, if left untreated, may progress to heat stroke.
York Region EMS offers the following preventative measures to protect your health when temperatures are high:
Reduce physical activity, especially in the full sun
If you must be out in the heat, try to plan activities before 11:00 a.m. and after 4:00 p.m., when the sun is less intense, and rest frequently to allow your body temperature to cool down. Attempt to be in the shade as much as possible and take extra precautions to protect seniors, infants and children.
Drink extra liquids and maintain adequate salt intake
Heavy sweating removes water, salt and minerals from the body. On hot days, increase your fluid intake regardless of your level of activity. During heavy exercise, drink 16 to 32 ounces (2 to 4 cups) of cool fluids each hour. Depleted salt and minerals can be replaced by drinking fruit juices or sports beverages. Keep in mind that even when you are in the water, your body is still sweating, and therefore, you still need to maintain fluid intake.
Monitor those at risk
Those at greatest risk of heat-related illness include:
• Infants and children up to four years of age
• The elderly
• Persons with high blood pressure, heart disease or chronic medical conditions
• Individuals taking certain medications, such as antipsychotic, major tranquilizers, antidepressants, antihistamines, sleeping pills and some medications to control Parkinson's disease. If in doubt, contact your family doctor
Use common sense
• Do not leave people or pets in parked vehicles
• Dress infants in cool, loose clothing and monitor fluid intake
• Dress in clothing that promotes the absorption of sweat
