I did a podcast not too long ago where I brought the audience along as I got up at 5:30 to exercise. This was great fun, and it did allow me to have a great day. I repeated, and the on the third day I had lots of work to get caught up on and also got 5 hours sleep. So over the weekend, I got around 15 hours sleep. I also noticed I had developed a scratchy throat. Fast forward a few days, and I'm stuffed up, developing a cough, and not feeling great. What do I blame? ME, and my lack of sleep. It turns out that people who get less than 7 hours per night are 3 times likelier to catch a cold, according to a JAMA study.
According to an article at yahoo.com lack of sleep has eight different negative side effects. These include:
1. You crave junk food
2. You become a germ magnet
3. You're less able to metabolize sugar
4. You're in a never-ending stress storm
5. You're in a foul mood and your brain feels foggy
6. You look older
7. You fell achy
8. You have a higher cancer risk
It's amazing what happens when you deprive yourself of sleep. Researchers tracked nearly 6,000 women for about a decade and found that workout buffs who slept 7 or fewer hours per night had a 50% greater chance of developing cancer than exercisers who got more Zzzs—similar to the risk of nonexercisers.
