1. Flu - though this isn't due to working at home, bloggers have been reporting serious cases of illness. I was lightheaded for a few hours today, but it passed. Last year, around this time, I was sick for days - something that hadn't happened to me for as long as I can remember.

2. Obesity - I've definitely gained weight working at home full-time for nearly a year now. I know it's bad, it's just not always easy to do something about it without a concerted effort.

3. Diabetes from obesity and inactivity. With diabetes becoming an epidemic, weight is something to watch very closely. I've tried to eat less per meal, but sometimes I end up snacking too often since it's easy to do so at home.

4. DVT - Deep vein thrombosis from inactivity or sitting in a cramped position for long hours, over extended periods. If you're over 40, or have had surgery or recently had a baby or surgery, or are susceptible to any number of risk factors. It's typically a traveller's disease but does strike people with sedentary lives.

5. Stroke or heart attack from DVT or other reasons.

6. Headaches from lack of fresh air.

7. insomnia - especially if you work and sleep in the same room/ studio.

8. Hoarseness of throat, due to not speaking all day. Unless you conduct a lot of phone calls from home.
