Why Dizziness In Morning Getting Up From Bed

Why?

Unless you have a History of other ailments relating to Blood Pressure, Brain, Vertigo, Ear or Spinal Cord problems, the explanation s this.

As you lie down flat , your heart need not pump as vigorously as it has to while standing,as it has no Gravity to act against, it pumps blood at a slower pace and your blood vessels relax.

When you stand up, the Gravity pulls Blood from the heart.

Brain, as usual grabs more Blood, it tells your heart to pump harder, and your blood vessels to contract which helps increase the blood flow to your brain (there are pressure sensors that help determine this).

As this process is taking place, occasionally your will get dizzy as a result of decreased blood flow to your brain.

Memory Is…… Yoga Sutra 1.11

After touching on what thoughts are and how we get them, Patanjali now is defining the important function of the Mind, 'Memory'

We come (our senses) come into contact with sense objects.

We become aware of them

Neurology explains the process thus.

We have neurons in our Nerves.

The neurons have two essential parts,

Axon and Dendrites.

These when the come into contact, through the appropriate sense, transmit the sensation, in the form of an electrical/magnetic impulses to the Brain.

( there is a debate whether these are transmitted as an electrical impulse or they are Magnetic;Indian Philosophy and Buddhism say it is an Magnetic Impulse)

These messages do not travel through a pipeline as it were.

There is a small gap between one neuron and another.

The gap is called the 'Synaptic Gap'

The impulses jump in the form of waves(electrical/magnetic)i to another neuron till the impulses reach the Brain or the Spinal Cord.

Depending on our Nature, the emergency and nature of the message , the Brain or the Spinal cord takes decision and reacts.

If we are sleeping, a mosquito votes us, the message is acted upon by the Spinal Cord..

If we see some things, then action is taken by the Brain.

Before this action takes place, the brain, after receiving the impulses (Stimulus), searches its memory bank to identify whether there is already some information there already and banks the stimulus there.

Then the Action center of the Brain takes charge.

It decides the action to be taken, based on the threat to the organism(individual) and selects a course already banked in the Data base, Memory.

In case the stimuli appears for the first time, action is taken on the basis of the threat level to the organism and the unconscious imprints of the actions already taken by the Brain earlier.

Then the message flashes out to the appropriate muscles through the Nervous System.

Then we react.

Patanjali goes to the roots here and talks about the 'Unforgotten experience' .

He does not say ' remembered', but says 'unforgotten'

We remember what we want to and forget what we want to.

Patanjali here says 'unforgotten' because the 'forgotten' ,(what we think consciously as" forgotten' this is a paradoxical concept), Memory includes those which we consciously think we have forgotten!

Many of us are aware a,that, at many an instance, memories of what we thought have forgotten rush to us suddenly.

Memory, a
