Aviso aos pais: apneia do sono afecta o cérebro das crianças

Como afecta as crianças e pode normalmente ser tratada então isso deve tornar-se uma prioridade:

Citação:
"Obstructive sleep apnea is a common sleep disturbance which affects up to five per cent of all children. 
(...)
Further, there is also a strong connection between sleep apnea and the loss of neurons or delayed neuronal growth in the developing brain. 
(...)

For this study, published in the journal Scientific Reports, the team evaluated sleep patterns of 16 children with obstructive sleep apnea (OSA). 

Each child also went through neuro-cognitive testing and had his or her brain scanned with non-invasive magnetic resonance imaging (MRI). 

They found reductions in the volume of gray matter in multiple regions of the brains of children with disrupted sleep. 

These included the frontal cortices -- which handle movement, problem solving, memory, language, judgement and impulse control -- the prefrontal cortices -- complex behaviours, planning, personality -- parietal cortices -- integrating sensory input -- temporal lobe -- hearing and selective listening -- and the brainstem -- controlling cardiovascular and respiratory functions. "

Fazer exercício físico em cidades poluídas pode fazer mais mal do que bem (pulmões e coração) - Estudo

Detalhes da poluição atmosférica nas cidades, como se mede e o facto de ser mau para o coração (e pulmões) fazer exercício em ambientes poluídos, principalmente para quem sofre de apneia obstrutiva do sono:

Citando:
"They found that air pollution makes it more difficult for the blood to flow into the lungs, specifically impairing the right ventricles.


Air pollution is measured in particulate matter (PM) - coarse dust particles which get into the lungs.


In London more than 3,000 deaths a year are attributed to particulate matter in the air and earlier this week it was revealed that three of the wealthiest boroughs had the highest rates of death caused by dirty air.


Despite a World Health Organisation recommendation that air pollution levels should not exceed a particulate matter rating of 2.5 micrometers at a maximal daily mean, cities worldwide regularly exceed the rating.


It was also found that patients with obstructive sleep apnoea - where the walls of the throat narrow during sleep - are most at risk."

"No strong evidence exists on effectiveness of face masks to eliminate or reduce particle exposure."
