Fatalities have been known in some cases. As well as the symptoms mentioned above, you may also experience vomiting, tinnitus, light-headedness, increased pulse, neck stiffness, and in extreme cases a loss of consciousness and cardiovascular failure are possible. In severe cases it can also lead to cerebral oedema. This causes irritation of the cerebral membrane and brain tissue. Sunstroke always occurs when the head and neck are exposed to hot sun for extended periods of time. Most of the time this diagnosis is correct. The diagnosis is simple - it must be sun stroke. Most of us have had this experience at some time or other: After a long day in the sun you start to feel dizzy, nauseous and headachy. Heat illnesses: Types, symptoms and procedures Individual fluid requirements can also be determined using our water requirement calculator. Hats with wide brims, Sunglasses and a cloth on the neck to protect the head you should of course also ensure that you drink enough water – and preferably isotonic liquids with salt, to replenish the minerals lost through perspiration, Drinking low-sodium water can in the long run lead to so-called water intoxication. The temperature, which is calculated using a relatively complex equation, is then used as a reference for the apparent temperature and has been converted into a warning table, which makes it easy to see at a glance how great the danger of heat stroke is for the human body: A noticeable shift in temperature perception only happens from around 27☌, which is why the Heat Index is only applied from this point. This is of course only a guide, since the subjective experiential temperature can be influenced by many factors, including background, age, weight, size, gender and health.įor temperatures under 20☌ the humidity has no influence on the apparent temperature. The Heat Index is used as a measure of the expected stress on the body, resulting from high humidity in combination with high temperature. However, the determining factor on the Heat Index is not the wind, but rather the relative humidity. The Heat Index is effectively the inverse of the wind chill, which gives an indication of the influence of the wind on the apparent temperature. This increase in the apparent temperature compared to the actual temperature is represented by the so-called Heat Index. Anyone who has travelled in the tropics could tell you a thing or two about how much the extreme humidity and heat can really wear you down.īut even in the lowlands of Europe, you can experience heat and humidity so bad that sweat pours off your body and the heat weighs you down. The number which appears at the intersection of the temperature and either the humidity on the left or the dewpoint on the left, is the heat index.Outdoor sports don’t always take place in the cool mountain regions of Central Europe. The humidity table is immediately below this and the dewpoint table is below it. In the heat index tables below, find the appropriate temperature at the top of the table. Heat Index Calculator ( From Relative Humidty ) The formula variables are: HI = Heat Index, T = Temperature (☏), RH = Relative Humidity (%)

If you would like to make a manual calculation of the Heat Index, here is the formula: with that behind us, the heat is OFF!) For those of you that are capable of mental math with a pencil and are up to a challenge, try this by hand. Enter data in either field and click anywhere in the calculator for the result to appear. If you are confused by Fahrenheit and Celsius, there is a converter as a part of the calculator. We have also provided tables below the calculators for those that don't feel like entering data and clicking the mouse. You should also know that possible increases of up to 15 degrees F are possible in full, open sunlight for more than an hour. The heat Index does not really occur below 85 degrees F. You may independently clear the values of either calculator to start over. The calculator will return the Heat Index and other relative information. In either calculator, enter the temperature in degrees (F) and the other factors (numerical entry only) then click on Calculate. This script calculates the Heat Index ( or 'feels like' temperature) from the relative humidity or from the dew point, along with the ambient air temperature in degrees Fahrenheit (F).
