Can you keep your eyes open when/while/at the time of sneezing?

Have I used the words in bold correctly? Are they all natural?

1- Can you keep your eyes open when/while/at the time of sneezing?
2- Can you keep your eyes open when/while/at the time you sneeze?

3- During summer I get tired when/while/at the time of cooking.
4- During summer I get tired when/while/at the time I cook.

With sneezing, "at the time of" would be very unnatural. "While" is OK but it's not my preference.

Can you keep your eyes open when you sneeze?

3 and 4 would just about work with "when" (and a comma after "summer"). I have no idea why cooking would be more tiring in the summer, though.

Because during summer in India, the average temperature is above 35 degree celcius and that too with so much humidity. People often get dehydrated. They get dehydrated more quickly if they are near the heat of flames. Thus they feel tired.

Could you please tell me why it is not correct to use while in 3 and 4.

Here is another one:

5- I watch TV while/when I do my homework.

I watch TV while I do my homework.

You do the two things at the same time.
