The cause of cluster headaches is unknown. They tend to run in families, which suggest genetics may play a role. They may be triggered by changes in sleep pattern and by certain medications. Symptoms of a cluster headache include unilateral pain in the face and head that is sharp in quality and very short in duration.
The normal temperature of human urine ranges from 94Â°F to 96Â°F (about 35 Â°C). The temperature of drug test sample must be measured during first 4 minutes after it was received, as it changes depending on ambient temperature. Acceptable range is from 90 Â°F to 100 Â°F (32 Â°C - 38 Â°C) , any sample with a temperature out of this range will immediately fall under suspicion.
Physical Attributes of Urine. 1. Color - yellow to yellow/tan 2. Odor - a distinct urine odor 3. Temperature - The human body's internal temperature is a constant 98.8 o F. When urine exits the body, it maintains a temperature of 96 o F (+/- 1 o F). Heat flows from hot to cold so when a hot object comes in contact with the cooler object, both objects will eventually reach equilibrium and their temperature will be equivalent to the surrounding environment.
