But i've asked the doc bout that before, he say its ok.
Just be careful and dun overwork.
LBP ; orthostatic (Postural )hypotension
Orthostatic hypotension is an excessive decrease in blood pressure that occurs when a person stands up, resulting in reduced blood flow to the brain and dizziness or fainting.
Dizziness or light-headedness that occurs when a person sits up or stands abruptly is the most common symptom.
Orthostatic hypotension is particularly common among older people.(but i'm not old sia.)
Orthostatic hypotension is not a specific disease but an inability to compensate quickly for changes in blood pressure. When a person stands up suddenly, gravity causes about a pint of blood to pool in the veins of the legs and lower body. As a result, the amount of blood returned to the heart and pumped out by the heart is reduced, and blood pressure falls. Normally, the body quickly responds to a decrease in blood pressure: The heart beats faster and more forcefully to increase its output of blood and the arterioles (small arteries) constrict to increase resistance to blood flow If these compensatory mechanisms malfunction or function too slowly—both of which commonly occur in older people—orthostatic hypotension may occur

Most people with orthostatic hypotension experience some faintness, light-headedness, dizziness, confusion, or blurred vision when they get out of bed abruptly or stand up after sitting for a long time. Symptoms are worse if people are tired, have been exercising, have consumed alcohol, or have eaten a heavy meal. A severe decrease in blood flow to the brain can cause the person to faint and even to have seizures.
(that's why i told you its best that i try not to stay up till so late at night.)
