| | | Explains psychiatrist Dayal Mirchandani, 'Sleep is a phasic activity -one of our basic body rhythms -mediated by sunrise and sunset -which keeps these in synch. Any rapid change in one's sleep timings is stressful and has a detrimental effect on health.' Human beings function on a 24-hour cycle known as the Circadian Rhythm. Forcefully reversing this order by working late in the evening or in night shifts can cause many health problems including gastrointestinal disorders and cardiovascular concerns. | |
