We have probably all known or heard of children falling asleep in class. This has often resulted in jokes and sarcasm by teachers and others but some children may genuinely not be able to stop themselves. Narcolepsy is a disorder of the sleeping/waking mechanism in the brain.
When the pupil falls asleep the priority is to ensure his safety. This may involve moving him if he has fallen asleep in a corridor etc. Where possible he should not be wakened but if the ‘nap’ goes on for a very long time, e.g. more than an hour, then it may be necessary to get medical help. For safety reasons it may be necessary to disapply pupil from swimming.
