Here are seven things that can make older people sleepy all of a sudden.
1. You started taking a new prescription medication.
Many over-the-counter and prescription drugs, like antidepressants, antihistamines, and others, can make you tired.
2. You're getting medical care or getting better after surgery.
Chemotherapy and radiation are two medical treatments that can make you feel tired.
3. It's a sickness
Illnesses like the flu, pneumonia, and UTIs can all make you tired because your body has to work harder to fight off the germs.
4. You're Anxious or Depressed
According to the NIA, emotions that are too strong can sometimes show up as physical symptoms like sudden, extreme fatigue.
5. You Have a Nutrient Deficiency
The Mayo Clinic says that low iron levels, which can happen when a person has iron-deficiency anaemia, can make a person feel tired and weak.
6. Sleep apnea affects you
Sleep apnea can make it hard for a person to breathe while they're sleeping, which can wake them up many times without them realising it.
7. You have a long-term illness
Dr. Cutler says that fatigue is a sign of hormonal problems, heart problems, lung problems, autoimmune disorders, and cancer.
