What causes sleep?

Question

Sometimes, I feel so tired that I just want to fall asleep anywhere, even in the middle of the day. It makes me wonder what actually makes us feel sleepy and fall asleep. Is it just about being tired?

I am not very sure, but I read somewhere that a hormone called melatonin is released in the dark which makes us sleepy. Does that mean looking at our phone screens at night completely stops this hormone from working?

I constantly worry about my sleep cycle because I read that chemical changes in the brain like adenosine buildup cause sleep. If we don't get enough sleep, it can affect our heart and immunity, so please try to maintain a strict sleeping schedule to avoid health risks.

Yes, sleep is mainly regulated by our internal biological clock and brain chemicals. Keeping a consistent sleep time really helps the body align with this natural cycle.

Amit Sharma · Answer

I know how stressful it is when your mind keeps racing and you wonder why your body isn't falling asleep naturally. Sleep is just our brain's way of clearing out toxins and recharging our body after a long day. Try to relax your mind first, the sleep will follow.

The physiological mechanism of sleep involves complex neurological pathways and neurotransmitters like GABA. If you are experiencing abnormal sleepiness or severe insomnia, you should visit a neurologist at a good hospital to get a proper evaluation.
