I have heard the claim:

sleeping requires more energy than watching TV.

I have heard the counter-claim - watching TV requires large amounts of energy.

My question is: Is there evidence to suggest that sleeping requires more energy than watching TV?

    $\begingroup$ It fits with biology, too. $\endgroup$ – Always Confused Sep 7 '16 at 15:17

    $\begingroup$ No, I'm saying this exists in the Zeitgeist. In common conversation. It is something that people talk about. These were the sites that came up when I searched for a truth that is commonly known. $\endgroup$ – hawkeye Sep 14 '16 at 20:52

From Harvard Health Publishing. The weights are in pounds, and the energy is shown in calories. These values are for over a 30 minute period.


This suggests that the claim is false; watching TV uses more energy than sleeping does.

  • $\begingroup$ Data is in pounds? Really? Pounds of what? Pounds sterling? $\endgroup$ – David Nov 5 '17 at 8:59
  • $\begingroup$ Pounds are a valid measurement of mass, see en.wikipedia.org/wiki/Pound_(mass). If you want me too, I can use kilograms, however for simplicity the data was in pounds and the conversion to kilograms gives decimal places, the removal of which reduces accuracy. $\endgroup$ – Modelmat Nov 6 '17 at 9:55
  • $\begingroup$ But that, I imagine, refers to the figures in bold. One could ask "mass of what?" But as the question is about energy, I assume the non-bold figures are energy, which does not have units of mass. $\endgroup$ – David Nov 6 '17 at 10:51
  • $\begingroup$ Oh, sorry. I didn't realise that. Fixing that up now, and I'll fix the table up when I get on a PC $\endgroup$ – Modelmat Nov 8 '17 at 9:19
