Technical Difficulties
How Does Technology Relate to Stress?
Let's look at our results!

- 40.3% IHS Students reported severe depression

- Most common stressors: lack of time & self-imposed stress

- #1 for lack of sleep - anxiety and lack of resilience
- Sitting w/ shoulders forward leads to tightness/pulling at opposing muscles in the back

- The farther your moves forward, the more work your spine has to do

- Work = Force x Distance

- Blue light reduces production of melatonin (natural sleeping hormone)

- Light picked up by cells behind eyeballs communicating it is morning

- Shorter restorative REM cycles, delayed circadian rhythms
-Overwork the muscles in your hands!

- Arteries, veins & nerves compressed

- Increases chances of tennis elbow & carpal tunnel
- Slower blink rate

- Eyes constantly refocus and readjust

- Viewing screens too close, eyes converge

- Reading dark print on an extremely bright background leads to muscles at temples to spasm

Eye Problems
Tennis Elbow

- Inflammation of the tendons in elbow

- Caused by overuse of forearm muscles

- Pain also spreads to forearm and wrist
Carpal Tunnel
- Condition of hand and fingers

- Caused by compression of a major nerve

- Nerve passes through a passage in front of the wrist, along flexor tendons of the hand
