Many people suffer from heat-related illnesses, which is when the body’s core temperature starts to go into overdrive from the hot temperatures it’s been in. A few of the symptoms you need to be on the lookout for include: • Dizziness • Light-headed • Weakness • Clumsiness • Poor coordination • Fatigue • Headache • Blurred vision • Muscle aches • Nausea • Vomiting If a person’s core temperature starts to rise too quickly, it can cause severe damage to your brain or other vital organs. Other issues that can limit your body’s ability to regulate your body temperatures include old age, youth (ages 0-4), obesity, fever, dehydration, heart disease, mental illness, poor circulation, sunburn and substance abuse. If heat stroke is left untreated, it will begin to affect your organs and other vital parts of the body to be damaged and become worse.
