Although it has yet to be proven that changes in body temperature determine our sleep habits, there does appear to be a relationship between the two. The most commonly experienced problem with circadian rhythm is jet lag. Jet lag occurs when a person travels across several time zones within a day or two. A typical flight across seas, often produces jet lag symptoms that can last for a week or more. These symptoms include daytime sleepiness, insomnia, indigestion, irritability and poor concentration.
Some people adapt more quickly than others, depending on the number of the time zones involved.
Another example of a jet lag scenario is a shift worker. Tips for coping with jet lag and shift work Allow extra time for adjustment during a trip or when switching to a new work schedule. Depending upon the new time zone, a 20 to 30 minute nap at a specific time of day can be useful in overcoming the jet lag symptoms. The occasional use of short-acting sleeping medications can help reduce the symptoms of the circadian rhythm disorder. Check with a healthcare provider before taking any medications and never mix sleeping pills with alcohol or a antihistamines.
