yw..hope you're good too hun

Overeating triggers dopamine, the brain's reward system. The more you overeat, the more dopamine is produced. And now high levels of dopamine are being linked to depression.
Overeating and depression are linked-common link dopamine
cycle:
1. overeat-> more dopamine->depression->overeat again and so on
vicious cycle really. and it is addictive.
a lot of depression-hormonal
serotonin
neuropinephine-thats what antidepressants are for, regulating neurop and serotonin
and now dopamine
what is serotonin?
its a 5HT transmitter. biologically derived from tryptophan.
Tryptophan is found in:
oats, nuts, yoghurt, milk, eggs, fish, poultry, sesame seeds, sunflower seeds, pumpkin seeds, bananas, cod, pumpkin, various green vegetables.
Serotonin regulates:
1. mood
2. sleep
3. appetite
intense spiritual experience can be associated with low levels of serotonin.
Dopamine levels can be raised by raising serotonin.
endorphins are the other transmitter that affects mood, 4 in total.
serotonin-satisfied feeling-eg after a run.
epinephrine-flight or fight response.
dopamine-sleep and waking cycles. stress, anxiety, very low carb diets can disturb dopamine levels. that jet lag feeling if there is a deficiency.
Exercise affects all FOUR neurotransmitters.
high levels of exercise-adrenaline and epinephrine. like flight or fight. thats why the yoga and chilling out afterwards is a good idea.
low to moderate levels of exercise-serotonin is boosted.
feeling-like the feeling you have when you're around close friends and family
when the serotonin levels rise, the dopamine levels tend to rise in accordance.
We have all experienced the good night’s rest that is typical following a good workout. However, we have probably also experienced the disrupted sleep that can follow intense exercise performed too late. It seem then that low to moderate intensity exercise has a positive effect on dopamine levels, while exercise that is very intense can lower dopamine levels, causing a disruption in sleep. In fact, one of the symptoms of overtraining is a disruption in the athlete’s sleep pattern.
We experience a rise in endorphins regardless of the type, or intensity of the exercise. However, the endorphin response to exercise becomes stronger with exercise frequency. It seems that the more exercise we perform, the more endorphins we produce with each exercise bout. While natural painkillers are never a bad thing, we do want to be careful of overtraining, which will disrupt sleep patterns, putting us at a greater risk of injury.
we can control mood through exercise
different intensities of exercise create different chemical responses in the body.
Serotonin can become depleted with
1. chronic stress or anxiety, (tick)
2. starvation or a low carbohydrate diet, (tick) and
3. inactivity (no exercise..tick), leaving you feeling depressed, irritable, moody, and exhausted.
Cortisol-reduce it to get rid of belly fat
cortisol-flight or fight response. its a hormone.
so to get rid of it, you have to chill out a bit more.
rise in serotonin-> rise in dopamine
(exercise-healthy way to get a buzz/activate the brain's reward system)
overeating-unhealthy way to get dopamine
