Hydrations The best way to avoid heat strokes and other heat disorders is to keep your body well hydrated. Drink a lot of water if you are exercising or working in hot conditions. Doctors usually recommend consuming eight or more glasses of water per day. Ventilation Remain in cool areas where your body can cool itself. If working in hot conditions, try to take a break to regain energy and to avoid overexposure to the sun. Clothing What you wear plays a big factor in how your body handles the heat. Light clothing and loose fitting clothing will help your body in breathing and cooling itself. It is fine to wear a hat or cap to protect yourself from the sun but once you feel warm, remove it. This usually traps the heat inside your body. Limit yourself It is also important to watch the amount of activities you are participating in during hot days. Don’t overdo it. Heat stroke and other disorders can take affect in less than an hour. If you feel warm or dizzy, it’s best to take time to rest. Are you fit to work during summer?
