Summer is in full swing and temperatures and the summer heat index are rising everyday. For most Texans, we have learned to cope with the extreme heat and plan our days and activities accordingly. But even the most experienced can fall prey to dehydration, heat exhaustion, or the more serious condition known as heat stroke. It can happen when you least expect. You don't want to fall victim to a situation that can be avoided by following these tips to avoid serious health conditions caused by too much sun or heat. Keep your outdoor excursions in the Texas Summer sun fun -- and safe. Plan your water consumption according to your environment and the extent of exertion and perspiration. Requirements change quickly with these two factors. Remember the effects of any medication you are taking. Some prescription drugs require greater liquid consumption. Don't be caught by this often overlooked issue. Remember the four contributing factors of dehydration: respiration, perspiration, urination, and defecation. Breath harder -- drink more water. Work hard -- drink more. Frequent urination or diarrhea -- more water. Athletic salt tablets can help in retaining liquids, but be careful you follow manufacturers' recommended dosages. Too much salt can have the opposite effect. Also make sure taking salt tablets doesn't interfere with any medications you are taking, you would probably only use salt tablets in a long hike situation or building project. Avoid the direct sunlight. The sun, can zap the moisture from your skin.  WearSunblock and a wide-brimmed hat, also wear sunglasses constantly. The statistics for burned retinas is high throughout the Western, Southwestern region of the country and people don't wear sunglasses enough to prevent damage to their eyes. Don't stop with the head. Lightweight cotton clothing can breath and help the natural cooling system of your body. Hiking without your shirt can feel wonderful but can add to your dehydration problems, not to mention sunburn issues. Take a break! It's fine to push it to the extreme, when the conditions are right. But on hot, sunny and dry days, schedule more breaks in the shade. And drink more water. While clothing is important, don't allow for tight waistlines or sleeves. Keep it loose fitting and let the air circulate where it can. Fishing guide shirts are great for this because they allow for ventilation. Consider cool electrolyte beverages to supplement, not replace, your water consumption. While these of type beverages are excellent in restoring natural moisture, water is still the king. Drink more water. Manage your hiking and outdoor activities according to conditions. If you really want to cover a long hike today, start early, break early, and resume when it cools. You'll still get there -- in one piece. If your pets are hiking with you account for their hydration needs as well, increase their water consumption and make sure they also get shade time. Dogs are much more suspectible to heat stroke than humans, they rely on panting to cool their bodies and this is not as effective as sweating. Tips: Be mindful of your body's hydration condition. Do you feel hot to the touch, or flush in the face? Know the danger signs! Pack in the extra water. Don't trust the surface water, which can disappear and be contaminated. Carry the extra load, and you could save your life. The excessive use of alcoholic beverages requires greater consumption of water to flush the system. Be careful how much you drink the night before. During times of heavy exertion, remember the sun is not your friend. Loose clothing and frequent breaks for shade are in order. Never trust your travel companion has planned out the water rations. Check it yourself, and drink more water. What You Need: Lightweight containers Carrrying straps Lightweight clothing Sunblock Wide-brimmed hat
