Caloric intake negatively influences sleep patterns in healthy
adults, according to a research abstract that will be presented on
Tuesday at SLEEP 2008, the 22nd Annual Meeting of the Associated
Professional Sleep Societies (APSS). The study, authored by Ioná
Zalcman, of Federal University of Sao Paulo in Brazil, focused on 52
healthy volunteers between 20-45 years of age. Food intake was analyzed
by a three-day food record. An overnight polysomnogram, or sleep test,
was performed to determine the sleep pattern.
According to the results, positive and statistically significant
correlations were found between total energy intake and late-night
snack energy intake and awakenings during sleep. Similarly, total
energy intake and late-night snack energy intake were significantly
correlated with apnea-hypopnea index.
“Previous studies have demonstrated that circadian distribution of
food intake is capable of modifying endocrine and metabolic patterns
during sleep. However, studies of the influence of food intake
distribution on sleep pattern are scarce. This study, which analyzed
the influence of energy intake on the sleep patterns in healthy
subjects, concluded that total energy intake and late-night snack
energy intake may increase sleep fragmentation in healthy subjects,
which might increase the effects of sleep restriction on nutritional
and metabolic balance. New studies on this area are needed to better
understand theses associations,” said Zalcman.
It is recommended that adults get between seven and eight hours of nightly sleep.
The American Academy of Sleep Medicine (AASM) offers the following tips on how to get a good night’s sleep:
- Follow a consistent bedtime routine.
- Establish a relaxing setting at bedtime.
- Get a full night’s sleep every night.
- Avoid foods or drinks that contain caffeine, as well as any medicine that has a stimulant, prior to bedtime.
- Do not bring your worries to bed with you.
- Do not go to bed hungry, but don’t eat a big meal before bedtime either.
- Avoid any rigorous exercise within six hours of your bedtime.
- Make your bedroom quiet, dark and a little bit cool.
- Get up at the same time every morning.
Those who suspect that they might be suffering from a sleep disorder
are encouraged to consult with their primary care physician or a sleep
specialist.
