Taking certain medicines in the morning rather than the evening may affect how effective they are Credit: Getty Images. Aspirin has been found to be more effective when taken in the evening , as are some antihistamine tablets for allergies such as hayfever. A recent human study suggests that radiation therapy may be more effective if administered in the afternoon rather than the morning. The cost of clinical trials soar if you have to start systematically testing for the right time of day to give a treatment.
Getting them to stick to a course of therapy is already tricky, but ensuring they take those drugs at a specific time is even more so. Some of us are larks and some night owls.
A significant proportion of the population also work night shifts, which can have its own impact on the circadian rhythm and health. This is problematic, because too little daylight and too much artificial light at night are disruptive to our biological rhythms and sleep.
Misaligned or flattened rhythms are a common feature of hospital patients. It is leading to questions about how seriously this is impeding their recovery and survival.
Some of the strongest evidence comes from patients with heart disease. However, timing may also affect our ability to recover from heart injury. One recent study suggested that for people undergoing heart valve replacement surgery, those who had surgery in the afternoon had half the risk of experiencing a major cardiac event during the following days compared to those who underwent morning surgery.
If all patients underwent afternoon surgery, this might result in one major event being avoided for every 11 patients, the researchers calculated. Other studies have indicated that, for patients recovering from a heart attack or heart surgery, those with greater exposure to daylight have higher survival rates and get out of hospital sooner. Animal studies are providing insight into why this might be.
When Martino and her colleagues exposed groups of mice either to normal or disrupted light-dark cycles after simulated heart attacks, they found significant differences in the number and type of immune cells that rallied to the heart , the amount of scar tissue — and, ultimately, survival rates. Mice whose circadian rhythms were disrupted, as they might be during a hospital stay, were more likely to die from their heart injury. Further studies have revealed differences in the type and number of immune cells that infiltrate injured heart tissue, depending on what time of day the injury occurs.
And so obviously their sleep and circadian rhythms are going to be profoundly disturbed during those first couple of days which are so critical for healing. August 4, Team GB strikes Olympic gold.
