Some people feel dizzy at night. In this blog, I will discuss seven possible reasons for dizziness that is worse at night and what to do.

Possible Reasons for Dizziness at Night

Reason 1: Low Blood Sugar

If you skipped meals during the day, you may have low blood sugar at night.

Low blood sugar can cause you to feel dizzy and lightheaded at the end of the day.

What to Do About Low Blood Sugar

You should avoid skipping meals during the day. Even if you are busy at work, you must at least have a snack. Avoid sugary breakfast and snack foods as they can cause a rebound dip in blood sugar later in the day.

Plan ahead to be sure you have time for a healthy lunch or snack during the day, so your blood sugar doesn’t drop too low by evening.

Also be sure to stay hydrated during the day to reduce any dizziness from dehydration.

Reason 2: Mental and Emotional Stress

If you have a stressful job or you feel stressed about life, you could feel dizzy at night due to stress. To learn more about five reasons that stress can cause dizziness and vertigo, click here.

What to Do About Mental and Emotional Stress

You may need to utilize stress management techniques to deal with your stress. You can get up early to exercise before you start work, or go to the gym after work to de-stress. You can use a meditation app or use breathing exercises during the day.

Setting boundaries, committing to realistic deadlines, and saying no when necessary can also help reduce your stress. If needed, you can seek professional help for stress management.

Reason 3: Alcohol

Some people rely on alcohol to unwind at the end of a long day. However, alcohol can trigger dizziness for some people. Alcohol can sometimes worsen dizziness for people with certain vestibular disorders. Alcohol can also interact with certain prescription medications.

What to Do About Alcohol

If you are turning to alcohol for stress relief, you may want to find more healthy ways to reduce stress. If you are socializing with alcohol such as at happy hour with your friends, be sure to drink one glass of water per alcoholic beverage to prevent dehydration.

If you are on any prescription medication, check the warning label or ask your pharmacist if your medication interacts with alcohol.

Reason 4: Improper Ergonomics

Some people feel dizzy at night after working on a computer, smartphone, or tablet due to improper ergonomics. If your office work space is not set up ergonomically, you can develop dizziness from your neck by the end of the day. To learn more about upper cervical dizziness, click here.

What to Do About Improper Ergonomics

You may need to raise your computer monitor, use an office chair with armrests, or get a wrist support for your keyboard. Some people choose to sit on a large fitness ball instead of sitting on a chair to improve their posture.

Many of my patients have transitioned to using a standing desk so their posture is better. If you work on a tablet, you can purchase a stand. Holding your phone up at eye level can relieve dizziness from your neck.

If you need a professional to help with your set up, you can consult a certified ergonomics professional.

Reason 5: Glasses

If you also feel headaches and eye strain after working on computer in addition to dizziness, then you may need new glasses.

When people need new glasses, they often develop dizziness, eye strain, fatigue, and even headaches after working on the computer or laptop for an extended period of time. The dizziness tends to get worse as the day goes on, peaking at night.

What to do about Your Glasses

You can get your eyes checked by an optometrist to see if you need new glasses or an updated prescription. Some people use computer glasses, while other patients prefer to use contact lenses.

Reason 6: Clenching Your Jaw while Working or Concentrating

People who clench their jaw while they’re working or concentrating may feel more dizzy at night. TMJ problems including clenching can cause dizziness.

What to Do About Clenching Your Jaw

The first challenge is to become aware that you are clenching your jaw during the day while working or concentrating. If you notice that you are clenching your jaw while you’re working or concentrating, you can purposefully relax and release your jaw.

Some patients even choose to wear a night guard while they are working. You can consult with a TMJ specialist or an orthopedic provider regarding options for clenching your jaw while working.

Stress management can also help.

Reason 7: BPPV

BPPV is the most common inner ear cause of dizziness and vertigo. People with BPPV sometimes feel worse at night in bed. Symptoms with lying down or rolling over in bed can include dizziness, vertigo, nausea, and a feeling of falling or being off balance.

People with BPPV usually feel better as the day goes on and may even feel normal by evening, only to feel dizzy again when they lie down to go to bed at night.

What to Do about BPPV

You can consult with a vestibular physical therapist or vertigo doctor to determine if you have BPPV. BPPV can usually be successfully treated with specific maneuvers by a skilled vestibular health care professional.
