Experts Weigh In: Should You Keep Taking Vitamin D After Summer?

Published

on

During the peak summer months, most healthy individuals can produce all the vitamin D they need by exposing the skin on their face, arms, and legs to sunshine for just a few minutes each day. Experts recommend seeking out sunlight during the middle of the day—between 10 a.m. and 4 p.m.—when the sun is highest in the sky and the UVB rays are strongest.

However, as summer winds down into autumn and winter—especially in locations farther from the equator—UVB rays tend to be weaker and therefore less impactful. As a result, you may be more vulnerable to developing a vitamin D deficiency, a condition that can affect your bone health, trigger a calcium imbalance in your blood, and cause muscle weakness, cramps, fatigue, respiratory problems, and more.

Brynna Connor, MD, a board-certified family medicine physician specializing in anti-aging and regenerative medicine and the Healthcare Ambassador for NorthWestPharmacy.com, says vitamin D deficiency can have far-reaching effects on health. In severe cases, it can cause osteoporosis in adults or rickets in children.

“Vitamin D helps your body absorb calcium more efficiently,” Connor says, noting that only 15 to 20 percent of the calcium you ingest through eating and drinking is absorbed by the body.
“When vitamin D becomes activated, it forms the hormone calcitriol that interacts with cells in the kidneys and intestines, triggering the organs to absorb more calcium.”

Since your natural absorption will vary depending on the sun’s intensity, you can plan your intake depending on the season. Endocrinologist John Bilezikian, MD, wrote on behalf of Columbia University Irving Medical Center that if you live in New York, for example, you should assume that the sun will provide “minimal or no vitamin D” between the months of October and April, regardless of how much time you spend outdoors.
“This is when supplements are vital,” he says.

Between May and September, Bilezikian says that getting between 15 to 20 minutes of sun exposure per day is enough. If you’re planning to be in the sun for longer stretches of time, it’s important to apply a high-SPF sunscreen to minimize your risk of sun damage and skin cancer.

The experts add that seniors over the age of 70 may need more time in direct sunlight since our skin becomes less efficient in producing vitamin D over time.

“Older adults who suffer from a vitamin D deficiency may also be more prone to falls, which, coupled with decreased calcium levels and weaker bones, can lead to increased incidents of fractures or breaks,” Connor warns.

Eating a diet that’s rich in vitamin D, including foods such as fatty or oily fish, egg yolks, mushrooms, and milk and dairy products, can also help to safely raise your levels. However, seeking out safe sun exposure and taking a daily vitamin D supplement are still considered the most effective ways to increase your vitamin D stores. According to the National Institutes of Health (NIH), most adults should aim to get 15 micrograms (mcg) or 600 international units (IU) of vitamin D. People in their 70’s or older should get 20 mcg/800 IU to protect against osteoporosis.

Of course, if you suspect you may have a vitamin D deficiency, your medical provider can confirm this with a blood test and help you determine the best solution for your unique medical circumstances.

“As with any supplement, you should talk to your doctor before starting a new course of treatment to ensure there is no risk of adverse events,” Connor advises.

Pain Relievers Linked to Increased Tinnitus Risk, Study Finds

Published

on

By

If you regularly use over-the-counter pain medications such as ibuprofen, acetaminophen, or aspirin, it’s important to be aware of potential risks. Recent research suggests that frequent use of these medications could increase the likelihood of developing tinnitus, commonly known as ringing in the ears.

A study published in the Journal of General Internal Medicine followed over 69,000 women for two decades. The findings revealed that those who frequently took nonsteroidal anti-inflammatory drugs (NSAIDs) or acetaminophen had nearly a 20 percent higher risk of experiencing tinnitus.

“Because over-the-counter analgesics are widely available without a prescription and perceived to be safe, frequent use of these medications is very common,” explains Sharon Curhan, M.D., the lead author of the study and an assistant professor of medicine at Brigham and Women’s Hospital, Harvard Medical School.

“Most people are not aware of the potential harm that these medications may cause and the possibility of adverse interactions with other medications, particularly when used frequently,” Curhan adds.

Many cold and sinus medications also include these painkillers, which can lead to unintentional overuse.

“It’s possible to take more of these medications than is intended or recognized,” Curhan notes.

Interestingly, the study found that frequent use of low-dose aspirin (100 mg or less) did not increase the risk of developing tinnitus. Curhan describes this as a “helpful finding,” especially for those who take low doses of aspirin to prevent cardiovascular issues and other conditions.

Moreover, women aged 60 and older who frequently took moderate doses of aspirin (325 mg or more) did not show an increased risk of tinnitus. However, the risk was higher among younger women. All participants in the study were initially between the ages of 31 and 48 and did not have tinnitus at the start.

Previous research has also indicated a connection between regular use of aspirin, NSAIDs, and acetaminophen and hearing loss in men. The new study emphasizes the need for further research on the relationship between pain medication and tinnitus in men and non-white women.

Understanding these risks can help you make more informed decisions about your health. Always consult with a healthcare provider before making any changes to your medication regimen.

Why You Might Be Losing Sleep and How to Fix It

Published

on

By

Suddenly finding yourself unable to sleep can be frustrating and perplexing. Insomnia can stem from various causes, and understanding these can help you regain restful nights.

Napping Habits

Many adults unintentionally fall asleep while watching TV or when not busy. According to Dr. Doghramji, “your brain sees it as sleep.” This often occurs between 2 and 3 in the afternoon, a natural energy dip time. This can make you less tired at bedtime, leading to insomnia. Instead of napping, consider scheduling an active task during this period to boost energy and improve sleep quality.

Nap Wisely

If a nap is unavoidable, Dr. Pelayo suggests keeping it under 40 minutes to avoid grogginess. It’s also beneficial to nap where you usually sleep to maintain a consistent sleep environment.

Bedtime Activities

Reading might seem like a relaxing pre-sleep activity, but Dr. Harris advises against doing it in bed.

“I prefer that the bed is only used for sleep and sex,” she says. Activities like puzzles or coloring can also make your brain associate the bed with wakefulness, affecting your ability to fall asleep.

Alcohol Consumption

A glass of wine might help you fall asleep initially, but it can cause fragmented sleep later. Research indicates that alcohol can lead to lighter sleep in the second half of the night, causing you to wake up around 3 a.m. To minimize this, limit alcohol intake to three hours before bedtime and drink moderately.

Medication Timing

Poor timing of medications can disrupt sleep. Diuretics for blood pressure can increase nighttime urination, and some antidepressants can be either energizing or sedating. Dr. Doghramji notes that taking more than one or two bathroom breaks at night is abnormal. Always consult your doctor before adjusting medication timings.

Managing Stress

Stress can make falling asleep difficult and lead to fragmented sleep. Dr. Pelayo suggests keeping stressors, like bills, out of the bedroom.

“Put it in a separate room so when you go to your room, it’s a different world,” he says. Journaling or making lists can help manage persistent thoughts.

Sleep Environment and Routine

Lying in bed trying to force sleep can backfire. Dr. Harris recommends getting up and doing something relaxing in a different room if you can’t sleep.

“Sleep will come when it comes. If not tonight, don’t sleep in to compensate — and you’ll likely sleep better the next night,” she says.

Sleep Disorders

Insomnia can be a symptom of over 80 sleep disorders, including sleep apnea, restless leg syndrome, and narcolepsy. Older adults are particularly susceptible to REM sleep behavior disorder (RBD), which can be an early warning sign of neurodegenerative conditions like Parkinson’s. Non-sleep disorders, such as pain, arthritis, and PTSD, can also cause insomnia.

Exercise

Exercise can improve sleep quality, but working out too close to bedtime might be counterproductive. Aim to exercise at least two hours before bed to allow your body to wind down.

Treatment Options

Cognitive Behavioral Therapy for Insomnia (CBT-I)

CBT-I is often the first-line treatment for insomnia, addressing habits and thoughts that keep you awake. Medication can be an option but comes with side effects, especially for older adults. A newer category of medication, dual orexin receptor antagonist (DORA), has shown promise for older adults with insomnia.

CBT-I can help retrain your thoughts to calm your mind. Dr. Doghramji suggests using CBT-I apps during the day to practice these skills.

When to Seek Help

If insomnia impacts your daytime function or persists despite self-help efforts, consult a doctor. Working with a sleep specialist can help identify the root causes and establish a personalized treatment plan.

“Modern sleep medicine has reached a point where most sleep disorder will improve when addressed correctly,” says Dr. Pelayo. “So you shouldn’t suffer with a sleep disorder anymore.”

Lung Cancer Screenings: 5 Million Adults Urged to Take Action

Published

By

Even if you haven’t touched a cigarette in decades, you might still need an annual lung cancer screening. This is based on the latest recommendations from the American Cancer Society (ACS).

The updated guidelines now suggest that adults aged 50 to 80 who currently smoke or have smoked the equivalent of one pack a day for 20 years should undergo an annual low-dose computed tomography scan (CT scan). This recommendation stands regardless of how long ago they quit smoking.

These new criteria, detailed in the journal CA: A Cancer Journal for Clinicians, expand screening recommendations to an additional 5 million adults.

Previously, the ACS guidelines stated that individuals no longer needed annual cancer screening if it had been 15 years since they quit smoking. It was also only recommended for current or former smokers between the ages of 55 to 74 who had smoked the equivalent of one pack a day for 30 years or more.

Robert Smith, the lead author of the guidelines and senior vice president of early cancer detection science at the cancer society, noted in a news release that the change is based on new studies.

These studies “have shown extending the screening age for persons who smoke and formerly smoked, eliminating the ‘years since quitting’ requirement and lowering the pack per year recommendation could make a real difference in saving lives.”

Maher Karam-Hage, M.D., professor of behavioral science at the University of Texas MD Anderson Cancer Center, highlighted the broader impact of these changes. He mentioned that broadening the eligibility criteria will help to “include more women and minorities, who typically smoke fewer cigarettes daily.”

“Reducing the age and pack-year requirements allows them to qualify sooner, potentially leading to earlier detection of any suspicious nodules or masses,” he told AARP in an email.

Pack-year is a measure used to describe how many cigarettes a person smoked and for how long. For instance, a person would have a 20-pack-year history if they smoked one pack a day for 20 years, or two packs a day for 10 years.
