The International Hyperhidrosis Society (IHS) has revealed that excessive sweating is not a sign of potential criminal activity at airports.
The IHS has indicated that excessive sweating can be a result of various conditions such as nervousness or a rare but debilitating dermatologic condition known as hyperhidrosis.
Airports are currently strengthening security measures by training officials to ascertain a passenger's body language and behaviour.
3% of the population suffer from hyperhidrosis and sweat profusely all day in focal areas such as the armpits, hands, feet and face.
According to the IHS, excessive sweating over large areas of the body can also indicate an underlying medical condition such as diabetes or tuberculosis, or a side effect of medications.
