feeling sleepy during office timing is most commonly caused by absence of a sound sleep at night. sleeping for 8 hours during night not always means that you are having a healthy sleep. a healthy sleep is determined by the following factors: duration of the sleep. sleep-wake timings. number of awakenings during sleep at night. daytime sleepiness or drowsiness. any distress or dysfunction associated with sleep disturbances. as you told that you are sleeping for about 8 hours at night and your age is 24 years this is an adequate sleep at this age (6-8 hours). however if you still feel sleepy during your office hours this can be due to inadequate sleep in terms of quality of sleep. ensure that you are sleeping at an adequate time and getting up at adequate time in morning. no frequent awakening at night which reduces the quality of sleep. besides this few other things also hamper sleep quality such as: affective states anxiety states psychosis. endocrine disturbances such as hypothyroidism or hyperthyroidism. activating agents like tea coffee stimulant abuse. underlying physical illness. lack of interest in work boredom and burnout syndrome at work place also can cause sleepiness. i would recommend you a few changes that you can make at your work place such as make your work area more stimulating work in chunks take breaks in between your work do not work for long hours at a stretch drink water in between avoid too much tea/coffee in order to work continuously get involved in conversations in between for a while to refresh yourself. also try and maintain sleep hygiene at bed time. besides this if you continue to have this problem seek an opinion from a sleep medicine physician online get yourself evaluated for any of the above causes for sleep disturbances --> <link>
