6.6.4. FOOD HYGIENE 

– A gain or a loss in weight indicates inappropriate or wrong food habits. 

– Lipid metabolism disorders are one of the most important factors in vascular risks. 

– Irregular meal times can cause digestive disorders linked with the circadian rhythms of the digestive enzymes' activities. 

– During night work, meals very rich in fats must be avoided as the stomach is accustomed to working less during night than in daytime. 

– Food rich in carbohydrates contributes towards reducing arousal level during the second half of the night. 

– Extra proteins can help in limiting the reduction in arousal level during night. 

– A good meal taken just before bedtime may disturb sleep. 

– When you sleep during the day (e.g. after a night flight or crossing several time zones), you may be awakened by hunger before having had sufficient amounts of sleep. 

– A meal of more than 600 kilocalories can cause drowsiness when taken during the night. 

– It is preferable to eat snacks of fruit or dairy produce. 

– Milk and dairy produce are rich in proteins that are found in all the tissues of the human body. 

– Fresh fruit and fruit juice are good sources of natural elements which rapidly provide energy.

– During short layovers after transmeridian flights, it is preferable to eat meals at normal times. Example: if you are on a short layover (< 48 hours) in New York, eat a good meal at local breakfast time as, for your organism, breakfast time corresponds to your normal lunch time. 

– However, during long layovers, eating meals at local times facilitates adjustment to local time in country of arrival. 

– To facilitate adaptation after a transmeridian flight, breakfast and lunches should be rich in proteins (e.g.: meat, eggs, cheese, yogurt…) to stimulate arousal, evening meals rich in carbohydrates (e.g.: potatoes, pasta, rice,…) to facilitate sleep. 
 

 
 
6.6.5.  PHYSICAL EXERCISE

– To better combat stress, and for the sake of a better state of mind, you are recommended to raise your heartbeat to an "athletic rate" for twenty minutes three times a week. 

– The minimum athletic rate corresponds to 180 heartbeats per minute less your age: 140 if you are 40, 130 if you are 50. Maximum rate is 220 beats per minute less your age.
