The word Non - communicable disease refers to the group of disorders or diseases which are non contagious or non infectious .
As non-communicable disease occurs due to genetic , environmental , physiological or lifestyle changes these are not passed from person to person, so these lasts for a longer period of time (chronic diseases) . Examples of these type of conditions are : diabetes , Alzheimer , cancers , asthma or any mental health conditions and respiratory diseases . These diseases can be aggravated by tobacco or cigarette use , unhealthy diets and sedentary lifestyle (physical inactivity ).

Answer:
True.
Explanation:
Stage 1 of NREM sleep is characterized by a low amplitude EEG, mixed frequency between range a and s (2 to 7Hz). EMG activity is usually higher than at other stages of sleep, but amplitude can vary widely. Stage 2 of NREM sleep is recognized by background activity and episodes of sleep spindles and K-complexes. Sleep spindles are short (12 to 14 Hz) waves that increase and decrease in amplitude to produce a spindle characteristic. Stage 3 NREM sleep is classified when slow waves or d waves (£ 2Hz) and high amplitude greater than 75mV (measured from lowest to highest wave - peak to peak) appear at 20 to 50% of the time of the day. record. Stage 4 NREM sleep is similar for EEG, EMG, and EOG from the previous stage; however, stage 4 is characterized by the presence of d waves in more than 50% of the time.
Accordingly, we can conclude that going through the NREM stages (1 to 4), the frequency of EEG waves decreases but their amplitude increases.
The more common of these conditions include: various anxiety disorders, asthma, hyperventilation, pneumonia, pulmonary edema, and shock. Anxiety, stress, and panic attacks often accompany shallow breathing.
