Chronic stress accelerates premature aging by shortening DNA telomeres. A wide range of studies have shown that the stress caused by things like: untreated depression, social isolation, long-term unemployment, anxiety attacks... can speed-up the aging process by shortening the length of each DNA strand.
The telomerase activity in HUVECs correlated inversely with the oxygen concentration. Mild hypoxia (10 or 15% oxygen) increased the telomere lengths, whereas the telomere lengths did not appear to change when <1% O2. The subtelomere of the shortest telomere range was methylated the most at 1% O2.
