In hot weather, your body is close to dehydration, and this can have an effect on your metabolism. Dehydration comes from the loss of water and salts from the body. We need water to maintain our blood volume and to ensure our other body fluids to function properly, as well as to maintain our blood pressure. The human body is made of around 60% of water. The brain tissue consists of about 85% of water, muscle tissue 75%, and blood 70%. Along with water, the body also needs electrolytes, which are salts usually found in blood, other fluids, and cells.
Symptoms: Dizziness, tiredness, irritability, thirst, dark yellow urine, loss of appetite, fainting.
What to do: Drink plenty of water. Move somewhere cold and, if possible, use a spray bottle to cool you down.
That usually affect people who sweat a lot during strenuous activity causing the body to lose salt and water. That can lead to heat cramps.
Symptoms: Muscle pains or spasms. Heat cramps can also be an early signe of heat exhaustion.
What to do: Stop all activity and lie in a cool place with your legs raised slightly. Drink water. Have a cold shower or bath, massage your limbs to ease the spasms and apply cool packs. If symptoms last, call your doctor.
That is the body’s reaction to losing excessive amounts of water and salt contained in sweat.
Symptoms: Heavy sweating, pale skin, fast and weak pulse rate, rapid and shallow breathing, muscle weakness or cramps, tiredness and weakness, dizziness, headache, nausea or vomiting, fainting. If symptoms last, call your doctor.
What to do: Move to a cool place and lie down. Remove excess clothing, take small sips of cold fluids, and have a cool shower, bath or sponge bath. Put fresh packs under the armpits, on the groin or the back of the neck to reduce body heat. If symptoms last for longer than one hour, call your doctor.
That occurs when the body temperature rises above 40.5 °C. It is the most severe heat-related illness and is a life-threatening emergency. Immediate first aid aimed at lowering the body temperature as quickly as possible is crucial.
Symptoms: A sudden rise in body temperature, red, hot dry skin (because sweating has stopped), dry swollen tongue, rapid pulse, rapid shallow breathing, intense thirst, headache, nausea and vomiting, dizziness, confusion, poor coordination or slurred speech, aggressive or bizarre behavior, loss of consciousness, seizure or coma.
What to do: Call immediately for an ambulance. Move the person to a cool, shaded area. Bring his temperature down any way you can. Give her small sips of water if she is conscious and able to drink. Do not give any medication. If the person is unconscious, lay her on their side and check she can breathe properly.
Aim for 8 to 12 glasses of water a day.
Drink even when you are not thirsty.
Hydrate more when working out. Consume six to eight ounces of water every 20 minutes when exercising, and then have two eight-ounce glasses afterwards to restore fluids.
Avoid drinking sodas, teas, fruits juices, and alcohols. They have a diuretic effect, causing fluid loss.
