Beat the heat

Here in toronto the heat is getting high and thought i would post some helpful tips to stay sain (mwuahaha) and prevent you from melting!

Understand why excessive heat causes problems for us. Heat pushes the human body beyond its limits and in the case of extreme heat and high humidity, evaporation is slowed and the body has to work extra hard to maintain its normal temperature. Problems occur when a person is over-exposed to heat or overexert themselves. Those most likely to be impacted negatively by excessive, prolonged heat include the elderly, young children, sick persons, and those who are overweight and unfit. It is important to recognize that over-exposure to heat can be fatal. Possible health problems include:

Heat cramps – these are muscular pains or spasms that occur as a result of heavy exertion. Although heat cramps are the least severe of heat health problems, they are a warning sign that your body is not coping well with the heat.

Heat exhaustion  – this occurs typically when people exercise heavily or work in a hot, humid place where bodily fluids are lost through heavy sweating. The blood flow to the skin increases, causing blood flow to decrease to the vital organs. This results in a mild form of shock. If this goes untreated, the victim's condition will worsen, the body temperature will continue to rise, and heat stroke might occur.
  Heatstroke the victim's temperature control system which produces sweating to cool the body simply stops working and the body temperature can rise high enough to cause brain damage and death. A victim in this situation needs to be cooled quickly. Note that sun stroke is usually applied as another term for heat stroke.

1. Obvious is to stay inside, if you do have to go outside please stick to shady spots and always always hydrate!!!

  • If your home isn't air-conditioned or cooled with a water-evaporation system, consider spending the warmest part of the day (or even night) in public buildings such as libraries, schools, movie theaters, shopping malls, and other community facilities. Many of these are specially opened by public authorities during a time of a heat wave, so check for extended hours. There are even local cooling centers opened in some places to help people cool down.
  • If your house has more than one story, or you live in a multi-story building, stay on the lowest floor out of the sunshine if the air conditioning is not available. You can put makeshift beds downstairs during the heat wave if needed; ask the concierge to sort out something for residents if you are part of a condominium.
  • Put on a fan. Circulating air can cool the body by increasing the evaporation rate of perspiration. A fan can help move the air around your house and will be useful for pulling in relatively cool air at night, but do not rely on a fan to keep cool during the day. A fan will not prevent heat-related illnesses when the temperatures are over 98.6ºF (37ºC). A cool shower is a much more effective way to cool off.

  • Heat exhaustion is a serious condition and should be treated as soon as possible. The symptoms of heat exhaustion include:
  • Heatstroke is an emergency. Anyone exhibiting the signs and symptoms of heat stroke should seek immediate medical attention. Symptoms include:
    • Red, flushed skin - may become pale
    • A body temperature of 106ºF (41ºC) or higher
    • Seizures
    • Extreme headache
    • Rapid breathing
    • Rapid pulse
    • Sweating ceases
    • Confusion
    • Unconsciousness.
