Question:

Why we losts sweetness sense on the toungue after having sweets ?

After having any sweets we lost the sensation of sweets while having tea or coffee.


Answers:

For the same reason we cannot see in the dark after a bright light has been shone in our eyes or we can't hear well immediately after listening to very loud music.

When a part of our body receives sensory input, that information is sent to the brain via electrical impulses through our nervous system.

If the signal is too strong when it reaches the brain, our brain becomes less sensitive to that signal so that we will not be overwhelmed. This can last for some time after.
