Chronic lack of sleep poses a lot of known debilitating effects such as fatigue, lack of clear judgment and decision making, inability to focus, slowed response, mood changes, irritability and reduced energy levels. Little did people know that with sleep imbalance, a lot more disruptions in body processes happen inside the body.
Latest researches look into other serious effects of lack of sleep. The UCLA research team released a report which says that losing sleep even for a night may cause abnormalities in cellular pathways which induces tissue damaging inflammation reactions. On the other hand, a good sleep can decrease the risk of heart disease and rheumatoid arthritis.
Inside our body, there is this substance which main task is to signal inflammatory processes – the nuclear factor (NF)-κB. It was observed that after subjects were deprived of sleep for just one night, the day after, activation of (NF)-κB signaling was significantly greater as compared to the baseline measurements. Interestingly, this increase was only seen among female subjects.
This finding, according to the team may strengthen the link between sleep disturbance and the wide array of medical conditions such cardiovascular disease, arthritis, diabetes, certain cancers, and obesity. Dr. John H. Krystal says, “the closer that we look at sleep, the more that we learn about the benefits of sleeping.”
Accordingly, another research by the Brigham and Women’s Hospital in Boston looked into the relationship of sleep imbalance and cardiovascular risks. Dr. Najib Ayas says, “sleep is probably one of the pillars to a healthy lifestyle. Too little sleep puts stress on the body.” This was after they found out that women who have been sleeping less and more than the usual sleeping hours had increased risk of developing heart disease.
