Low level light therapy (LLLT) increases oxygen consumption rates. Oxygen consumption rates were measured in intact U2OS cells for 5 min, and then for an additional 5 min immediately following LLLT treatment. Data represent the $\text{mean}\pm \mathrm{SEM}$ of at least three separate experiments with $n=3$ per experiment. ****$P<0.0001$ compared to untreated control.

Treatment condition	Oxygen consumption rate ($\mathrm{nmol}/1\times {10}^6\text{\hspace{0.17em}\hspace{0.17em}cells}/\min$)
Control	$0.79\pm 0.03$
Laser 652 nm	$3.71\pm 0.13$****
Laser 806 nm	$3.42\pm 0.14$****
LED 637 nm	$3.46\pm 0.20$****
