Obesity, sleep and exercise; Autism and bacteria; Memory improvement

Back with teenage obesity talk again. New links are unfolding between the number of sleep hours and type of food choice. Adolescents who sleep for fewer hours than required tend to choose more fast foods whereas, those who sleep plentiful make healthier food choice. And it’s worth noting that eating a lot of high calorie fast food directly increases body weight. American Academy of Pediatrics recommends teens to get a sleep of 9-10 hours nightly. So teens may rethink how they can sleep more, may be watching less TV at night or cutting some of those late night parties.

Moving forward with obesity talk, have you ever wondered why or how exercise may be related to decrease in weight loss. Yes exercise burn calories, but there is something more too. Recently a small study revealed that after strenuous exercises our appetite decrease therefore, we consume lesser calories and it may help maintain our body weight. Although the long term effects of such exercises are yet to be unfolded.

Next in today’s discussion is autism. Although in previous posts we discussed about various potential relation of autism with social and environmental factors, today we will look into a new interesting finding. A study of autistic children’s gut bacteria showed that they have lesser number of bacteria than non-autistic children. Previously gut bacteria were said to be related to various health function like digestion, maintaining body weight etc. Autism link is new in that list.

Finally, are you a crazy book worm type individual? If yes there is something good for you today. Reading novels in the class hiding it under the desk is probably common in almost all countries. Well these book worms are actually insuring their old age mental health (although the author don’t encourage under-desk hiding reading habit in class). Reading habits (or those who prefer writing a lot) can preserve our memory power for future. And the best thing is even if you are an elderly with no habit of reading/writing you can start now too because the study shows that brain stimulating activities at any age boosts memory. So try making reading and writing a new pass time.
